The formula for the area of a trapezoid is A = 1 2 h ( b 1 + b 2 ) , A= 2 1 ​ h(b 1 ​ +b 2 ​ ), where h h is the height and b 1 b 1 ​ and b 2 b 2 ​ are the two bases. Rewrite the formula to solve for h h in terms of A , A, b 1 b 1 ​ and b 2 . b 2 ​ .

Answers

Answer 1

Answer:

h =  2A / (b1 + b2)

Step-by-step explanation:

A = 1/2h (b1 + b2)

Divide both sides by 1/2 (b1 + b2)

h  =  A / 1/2 (b1 + b2)

h =  2A / (b1 + b2)

Answer 2

Answer:

2A /  (b1+b2)  = h

Step-by-step explanation:

The formula for the area of a trapezoid is

A = 1/2 (b1+b2) *h

We want to solve for h

Multiply each side by 2

2A = 2*1/2  (b1+b2) *h

2A =  (b1+b2) *h

Divide each side by  (b1+b2)

2A /  (b1+b2)  =  (b1+b2) / (b1+b2) *h

2A /  (b1+b2)  = h

Jaden is in charge of building a dance floor for the school dance. He wants to build the largest dance floor that he can while staying within the budget. His plan is to buy wooden planks and lay them side by side on the grass just outside the gym. A plank that 2 inches thick, 4 inches wide, and 8 feet long costs $3.25. How large of a dance floor, in square yards, can he build with $526.50?

Answers

well you can buy 126 planks so it would be 648 inches wide and 1,008 feet long

Jaden can build a dance floor measuring 48 square yards with his budget of $526.50, based on the cost of $3.25 per wooden plank.

To calculate the size of the dance floor Jaden can build with his budget, we first need to determine how many wooden planks he can purchase. Each plank costs $3.25 and he has $526.50 to spend.

Number of planks = Total budget / Cost per plank
= $526.50 / $3.25
= 162 planks

Next, we need to find out the area that each plank covers. Since each plank is 8 feet long and 4 inches (or 1/3 feet) wide, its area in square feet is:

Area per plank = Length * Width
= 8 feet * 1/3 feet
= 8/3 square feet

Now, let's calculate the total area covered by 162 planks:

Total area in square feet = 162 planks * [tex]\frac{8}{3}[/tex] square feet/plank
= 432 square feet

Since 1 square yard is equivalent to 9 square feet, we convert the total area to square yards:

Total area in square yards = Total area in square feet / 9
= 432 square feet / 9
= 48 square yards

Therefore, Jaden can build a dance floor measuring 48 square yards within his budget.

Answers

$3 is for the magazine and $4for the four books and $5 for the amount of money

The total cost for the magazine and 4 paperback books is $23.

What is an Algebraic expression?

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Given that,

The cost of a magazine is $3.

And, the cost of each of 4 paperback books is $5.

Then, the cost of 4 paperback books is 4 × 5 = 20

Thus, the expression for the total cost is given as,

3 + 4 × 5

= 23

Hence, the total cost is given as $23 and the terms in the expression 3 + 4 × 5 represent the cost of magazine and that of 4 books respectively.

rebecca is given two triangles, ABC and DEF. at first glance, she thinks that the triangles are congruent l. how can she use what she knows about rotations and triangle congruence to prove the triangle congruence?

Answers

Answer:

She can use rotation and overlap the two triangles, and if they overlap perfectly/identically, that means they are surely congruent.

Rebecca can prove triangle congruence by applying the rotation property. If she can rotate one triangle to align with the other, maintaining the same shape and size, then the triangles are congruent. Additionally, she can compare corresponding angles and sides to confirm congruence.

Rebecca can use rotations to prove triangle congruence by performing a sequence of rotations, translations, and reflections on one triangle to align it with the other. If she can manipulate one triangle to superimpose it exactly onto the other triangle without changing its shape or size, then they are congruent. She can also use the properties of triangle congruence, such as side-angle-side (SAS), angle-side-angle (ASA), side-side-side (SSS), or angle-angle-side (AAS), to verify their congruence. By demonstrating that the corresponding sides and angles of the two triangles are congruent based on these properties, she can conclusively prove their congruence. This approach ensures that both triangles share identical measurements and configurations, providing geometric evidence for their congruence.

Then once you do that, you should come up with 35.96. Then subtract 50.81 from 35.96,which should give you 14.85. Then just divide 14.85 by 0.99 to figure out the amount of pretzels he bought.It should give you 15.Hope this helps!!!!

Please give brainliest!!!☺


Answer:

15

Step-by-step explanation:

Danny buys 4 pizzas and some pretzels for his baseball team.

The cost of each pizza is $8.99

Total cost of 4 pizza = 4 × 8.99

                                  = $35.96

Let buy p numbers of pretzels whose cost $0.99 each.

Total cost for p pretzels = 0.99p

Total  spend by Danny on pizzas and pretzels = $50.81

                               35.96 + 0.99p = 50.81

                                             0.99p = 50.81 - 35.96

                                             0.99p = 14.85

                                                     p = 15

Hence, Danny bought 15 pretzels for baseball team.

A company makes traffic signs.One of their signs can be modeled by an equilateral triangle with a perimeter of 144 inches. The company makes a similar sign with perimeter that is 1.25 times the one shown. What is the height in inches of the larger sign?

Answers

Answer:

The perimeter of the larger sign : 144*1,25= 180 inches

Side of the triangle= 180/3= 60 inches

square of the height= 60^(2) - 30^(2)= 2700 ( Pythagoras' theorem)

height= square root ( 2700)= 51,96

Step-by-step explanation:


Final answer:

To find the height of the larger sign, determine the scale factor between the two signs and use the formula for the height of an equilateral triangle.

Explanation:

To find the height of the larger sign, we need to determine the scale factor between the two signs. The perimeter of the original sign is 144 inches, and the new sign has a perimeter that is 1.25 times the original. This means the perimeter of the new sign is 144 x 1.25 = 180 inches.

Since the original sign is an equilateral triangle, each side has a length of 144/3 = 48 inches. The larger sign will have sides that are 180/3 = 60 inches in length.

Since the larger sign is also an equilateral triangle, we can use the formula h = (√3/2) x s, where h is the height and s is the length of a side. Therefore, the height of the larger sign is h = (√3/2) x 60 = 51.96 inches (rounded to two decimal places).

Estimate the square root of 4.92+2.18x7.31

Answers

Answer:

4.36

Step-by-step explanation:

The given expression is

[tex]\sqrt{4.98+2.18\times 7.31}[/tex]

We need to estimate the value of given expression.

First approximate each term of the given expression.

First term : [tex]4.92\approx 5[/tex]

Second term : [tex]2.18\approx 2[/tex]

Third term : [tex]7.31\approx 7[/tex]

The value of given expression after approximation is

[tex]\sqrt{5+2\times 7}[/tex]

[tex]\sqrt{5+14}[/tex]

[tex]\sqrt{19}[/tex]

The approximate value of [tex]\sqrt{19}[/tex] is 4.36.

Therefore, the estimated value of given expression is 4.36.

The estimated square root of 4.92 + 2.18 x 7.31 is between 4 and 5.

To estimate the square root of 4.92 + 2.18 x 7.31, we first calculate the value inside the square root:

4.92 + 2.18 x 7.31 = 4.92 + 15.8678 = 20.7878

Next, we estimate the square root of 20.7878:

Since the square root of 16 is 4, and the square root of 25 is 5, we can estimate that the square root of 20.7878 is between 4 and 5.

Therefore, the estimated square root of 4.92 + 2.18 x 7.31 is between 4 and 5.

ou work at the Peacock Blue store 40 hours/week over five days at a rate of $10.25/hour. Deductions are FICA (7.65%), federal withholding (15%), and state withholding (10%). Your expenses are transportation at $5.25/day, lunch at $3.85/day, and black slacks required for work at $19.95. How much is your discretionary income for one week?

Answers

Answer:

$210.69

Step-by-step explanation:

Firstly, just calculate how much money you earn:

40 * 10.25 = $410

Your transportation expenses = 5.25 * 5 = $26.25

Your lunch expenses = 3.85 * 5 = $19.25

Expenses for black slacks = $19.95

FICA = 7.65/100 * 410 (money you earned) = $31.365

Federal withholding = 15/100 * 410 = $61.5

State withholding = 10/100 * 410 = $41

Your discretionary income = 410 - (26.25 + 19.25 + 19.95 + 31.365 + 61.5 + 41) = $210.69

C. y < or = 3x - 4
D. y > or = 3x - 4

Answers

Answer:

D. y > or = 3x - 4

Step-by-step explanation:

Looking at the graph, we know the y intercept, or where the graph crosses the y axis, is -4.

We can find the slope of the line from 2 points (0,-4) and (2,2)

The slope is  given by

m = (y2-y1)/(x2-x1)

   = (2--4)/(2-0)

  = (2+4)/(2-0)

   =6/2

   =3


Using the slope intercept form for the line, y=mx+b

y = 3x+-4

y = 3x-4

The graph is shaded above the line so y is greater than the line, and the line is solid so y is also equal to the line

y ≥3x-4

Mya takes a drive from a springboard at a swimming pool. The board is 3 1/2 feet above the surface of the water. The total length of her dive is 8 3/4 feet. How far below the surface of the water is mya at the end of the dive

Answers

Answer:

dive below = 5 1/4 ft

Step-by-step explanation:

Dive above water + dive below water = total dive

We know the dive above water is 3 1/2 ft

The total length of the dive is  8 3/4 ft

Substitute in what we know

3 1/2 + dive below = 8 3/4

get a common denominator of 4

3 1/2*2/2 +dive below = 8 3/4

3 2/4 +dive below = 8 3/4

Subtract 3 2/4 from each side

3 2/4 - 3 2/4 +dive below = 8 3/4 - 3 2/4

dive below = 5 1/4 ft

Final answer:

To find out how far below the surface of the water Mya is at the end of her dive, subtract the diving board's height from the total dive length. Convert mixed numbers to improper fractions for easy subtraction, and after calculation, you find that Mya is 5 1/4 feet below the water's surface.

Explanation:

To determine how far below the surface of the water Mya is at the end of the dive, we need to subtract the height of the diving board from the total length of the dive. Mya's dive board is 3 1/2 feet above the water, and the total length of her dive is 8 3/4 feet.

First, convert the mixed numbers to improper fractions to make the subtraction easier. For 3 1/2, multiply 3 (the whole number) by 2 (the denominator) and add 1 (the numerator) to get 7/2. For 8 3/4, multiply 8 by 4 and add 3 to get 35/4.

The fractions are now 7/2 and 35/4. Before subtracting, find a common denominator, which is 4 in this case.

Convert 7/2 to 14/4, so we can subtract it from 35/4.

Subtract 14/4 from 35/4 to find the distance below the water's surface: 35/4 - 14/4 = 21/4.

Finally, convert the improper fraction back to a mixed number. The mixed number for 21/4 is 5 1/4, which means Mya is 5 1/4 feet below the surface of the water at the end of her dive.

The price of a Barry bonds baseball card in 2001 was $50. It is now being sold for $30. Find the percent decrease in the cost of the card

Answers

The cost of the cards decreased by 40%

Final answer:

The percent decrease in the cost of the Barry Bonds baseball card is 40%.

Explanation:

To calculate the percent decrease in the cost of the card, we can use the formula:

Percent decrease = ((original value - new value) / original value) * 100

In this case, the original value of the card was $50 and the new value is $30. Plugging in these values into the formula:

Percent decrease = ((50 - 30) / 50) * 100 = (20 / 50) * 100 = 0.4 * 100 = 40%

Therefore, the percent decrease in the cost of the card is 40%.

You are making a poster to support your friend for homecoming. Your original photo is 3 inches by 5 inches. You want the photo on the poster to be 2 1/2 feet by 4 1/6 feet. What is the scale factor of this dilation?

Answers

Answer:

9

Step-by-step explanation:

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.            


First of all we will convert dimensions of poster from feet to inches.

3ft = 3x12 in = 36ft

4 1/2 ft = 4.5x 12in = 54in

Now let us compare sides of our original photo with corresponding sides of poster.

frac{36}{4}  = 9

Now let us compare the second pair of corresponding sides.

\frac{54}{6} =9

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.      


Final answer:

To find the scale factor for enlarging a photo from 3 inches by 5 inches to 2 1/2 feet by 4 1/6 feet, first convert feet to inches and then compare the dimensions of both photos. The scale factor is 10, as both width and height are enlarged by a factor of 10.

Explanation:

You are making a poster and need to determine the scale factor for resizing a photo from 3 inches by 5 inches to 2 1/2 feet by 4 1/6 feet. To find the scale factor, you compare the dimensions of the enlarged photo to the original photo.

First, convert the measurements of the larger photo from feet to inches, since the original photo is in inches (1 foot = 12 inches):
2 1/2 feet = 2.5 * 12 inches = 30 inches
4 1/6 feet = (4 + 1/6) * 12 inches = (4 * 12) + (1/6 * 12) inches = 48 + 2 inches = 50 inches.

Next, calculate the scale factor for each dimension separately and check that they are consistent:
Scale factor for width = 30 inches / 3 inches = 10
Scale factor for height = 50 inches / 5 inches = 10

Since both width and height have the same scale factor of 10, the overall scale factor for the dilation is 10.

The school play started at 2:10pm and ended at 3:22pm. How long did the play last?

Answers

2:10=>3:10, was 1 hour
3:10=> 3:22, were 12 minutes

the play last 1 hour 12 minutes (or 60+12= 72 minutes).

Answer:

The play lasted 1 hour and 12 minutes.

Step-by-step explanation:

Start: 2:10 pm. End: 3:22 pm.

3 hours - 2 hours = 1 hour

Start: 2:10 pm. End: 3:22 pm.

22 minutes - 10 minutes = 12 minutes

The play lasted 1 hour and 12 minutes.

which fact would help Estelle prove that the measure of angle KNQ is equal to the measure of MNS

Answers

Final answer:

To demonstrate that the measure of angle KNQ is equal to the measure of angle MNS, one should use geometric principles to show congruency or similarity between the angles, which could involve establishing congruent triangles or proportional relationships.

Explanation:

To prove that the measure of angle KNQ is equal to the measure of angle MNS, one would need to establish a relationship between the two angles based on geometric principles or congruent triangles. This could involve demonstrating that the angles are corresponding angles of similar triangles, alternate interior angles of a transversal crossing parallel lines, or possibly vertical angles resulting from intersecting lines. Given the information provided, it seems that if one could show that triangles KNQ and MNS are congruent, then by the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) theorem, it would follow that the angles in question are equal.

Applying trigonometry in proving congruency or similarity might be necessary, especially if an equivalence can be drawn from given proportional relationships or if one can establish that angles are congruent through right triangles and the definition of trigonometric ratios.

Brenda deposits $500 in a savings account that pays a simple interest rate of 2.5% per year. How much internet will Brenda earn after 18 months

Answers

Final answer:

Brenda will earn $18.75 in simple interest after 18 months on her $500 deposit at a 2.5% annual simple interest rate.

Explanation:

To calculate the simple interest Brenda will earn after 18 months on a $500 deposit at a simple interest rate of 2.5% per year, we can use the simple interest formula:
I = P * r * t, where:

I represents the interest earned,

P is the principal amount (the initial amount of money),

r is the annual interest rate (in decimal form), and

t is the time in years.

First, convert the interest rate from a percentage to a decimal by dividing by 100:

2.5% = 2.5 / 100 = 0.025

Next, since the time is given in months, convert it to years:

18 months = 18 / 12 = 1.5 years

Now, plug the values into the formula:

I = $500 * 0.025 * 1.5

I = $18.75

Therefore, Brenda will earn $18.75 in simple interest after 18 months.

Of the various sleep disorders, the most widespread is insomniadifficulty in falling or staying asleep. Insomnia may be due to a particular situation, such as the breakup of a relationship, concern about a test score, or the loss of a job. Often, however, insomnia has no obvious cause. Some people are simply unable to fall asleep easily, or they go right to sleep but then wake up frequently. Insomnia afflicts about a quarter of the population of the United States. Interestingly, many who think they have insomnia are mistaken. Observers find that patients who enter sleep laboratories for treatment may sleep much more than they think they do. For example, researchers report that some people who claim to be up all night actually fall asleep in thirty minutes and stay asleep all night. Furthermore, some people can accurately recall sounds they heard while asleep. As a result, they believe that they were awake during the night. In many cases, just becoming aware of how long they really do sleepand understanding that the older they become, the less sleep they needis enough to cure peoples perception that they have a sleep disorder. In fact, some researchers believe the twenty-first century will lead to drugs that act by changing peoples perceptions of how much they have slept, rather than making them sleep more. Other sleep problems are less common than insomnia and perceived insomnia, although they are still widespread. For instance, some 20 million people suffer from sleep apnea, a condition in which a person has difficulty breathing and sleeping simultaneously. The result is disturbed, fitful sleep, as the person is constantly reawakened when the lack of oxygen becomes great enough to trigger a waking response. In some cases, people with sleep apnea wake as many as 500 times during the course of a night, although they may not even be aware that they have wakened. Not surprisingly, such disturbed sleep results in complaints of fatigue the next day. Sleep apnea may also account for sudden infant death syndrome, a mysterious killer of seemingly normal infants who die while sleeping. Narcolepsy is an uncontrollable need to sleep for short periods throughout the day. People with narcolepsy go directly from wakefulness to sleep. No matter what the activityholding a heated conversation, exercising, even drivingthe narcoleptic will suddenly slip into sleep. The causes of narcolepsy are not known, although it appears to run in some families. 1. Which sentence best states the main idea of the passage? a.
