A builder uses 32 wooden slats to make 4 fence panels. Fatima wants to know how many slats are needed for 1 panel. Gerard wants to know how many slats he will need to make 8 panels. Drag an expression to answer each question.

Answers

Answer 1

1 fence panel required 8 wooden slates and 8 fence panels required 64 wooden slates.

What is ratio?

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Wooden slates required to make 4 fence panels = 32

To find wooden required to make 1 panel, use ratio property,

4 fence panels = 32 wooden slates

1 fence panel = 8 wooden slates

Also, to find wooden required to make 8 panels, use ratio property,

4 fence panels = 32 wooden slates

8 fence panels = 64 wooden slates

1 fence panel required 8 wooden slates and 8 fence panels required 64 wooden slates.

Answer 2

Final answer:

Gerard needs 64 slats to make 8 panels, as it is a proportional relationship.

Explanation:

To find out how many slats are needed for one panel, we simply divide the total number of slats by the number of panels. Since a builder uses 32 slats to make 4 panels, for one panel, Fatima would need:

Number of slats for one panel = Total number of slats \/ Number of panels

Number of slats for one panel = 32 / 4 = 8 slats

For Gerard's question, if 1 panel requires 8 slats, then to make 8 panels he would need:

Number of slats for 8 panels = Slats per panel x Number of panels

Number of slats for 8 panels = 8 x 8 = 64 slats

It's a straightforward example of a proportional relationship in mathematics, where the number of slats scales directly with the number of fence panels.

What is the name of an interior angle of a triangle that shares a side and a vertex with an exterior angle of the triangle?

A) exterior angle
B) adjacent interior angle
C) remote interior angle
D) alternate interior angle

Answers

Answer: B) Adjacent interior angle

As the name implies, the angle is inside the triangle and it is adjacent (ie next to) the exterior angle. Contrast this with a remote interior angle, which is also inside the triangle, but it is not adjacent to the exterior angle in question. Alternate interior angles won't apply here because we don't have a set of parallel lines with a transversal cut.

Answer:

The zeros of a graph form the factors of the function. When we multiply the factors out and add the exponents up in the final function, we have the highest exponent known as the degree.

Step-by-step explanation:

A polynomial graph has several features we look for to determine the equations.

The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity. Degree is the exponent or multiplicity of each zero. Therefore if we know the multiplicity of each zero we can add them together to find or make an educated guess for the degree of the entire polynomial. The shape of the graph tells us what type of polynomial. Odd degrees have a backwards S shape. Even degrees have a W shape. The shape can even tell us the if the equation has a positive or negative leading coefficient. Upside down W or an M shape is negative. While a sideways S shape is negative.

Adam bought A new pair of baseball cleats for $65 the sales tax is 5.5% what is the total cost in dollars that Adam will pay

Answers

(65×5.5%)+65 = 68.575
Final answer:

Adam's cleats cost $65 and the sales tax is 5.5%. The sales tax amount is calculated by multiplying the price by the tax rate. The total cost is the sum of the initial price and the sales tax which is approximately $68.58.

Explanation:

Adam is buying a new pair of baseball cleats for $65 and the sales tax is 5.5%. To find the total cost, we must find out the cost of the sales tax first. The sales tax can be calculated by multiplying the cost of the cleats by the sales tax percentage (in decimal form).

So, $65 * 0.055 = $3.575 is the tax amount. This means the sales tax on the cleats is $3.575.

The total cost Adam needs to pay is the sum of the cost of the cleats and the sales tax. Hence, $65 + $3.575 = $68.575. Therefore, the total cost that Adam will pay is approximately $68.58, because we usually round the money amount to the nearest cent.

We can assume that Rob earning's equation would be y = 15x-6x

We are also given that he earned $75 (My gosh Rob nice work man!)

we would plug in 75 for y >>>for now forget the fact that Rob saves<<<

Divide 75 by 15 which = 5

The correct answer to the question is therefore C. 2 + square root of 3.

If (2 - square root of 3) is a root of a polynomial with integer coefficients, the polynomial must have another root that is the conjugate of (2 - square root of 3), which is (2 + square root of 3). This is due to the Conjugate Root Theorem, which is a result of the fact that the coefficients of the polynomial are real numbers. When you have a non-real root in such a polynomial, its conjugate will also be a root.

The minute hand of a clock is 8 inches long. How far does the tip of the minute hand move in 30 minutes? How far does it move in 20 minutes?

Answers

Answer:

In 30 minutes:

The minute hand moves a distance of 25.13 inches

In 20 minutes:

The minute hand moves a distance of 16.76 inches

Step-by-step explanation:

When 60 minutes are completed, the minute hand of the relog makes a complete revolution. The distance s that the minute hand travels when making a complete revolution is:

[tex]s = 2\pi r[/tex] Where r is the radius of the circumference, and in this case, the radius of the minute hand.

So:

[tex]s = 16 \pi[/tex]

s = 50.27 inches.

In 30 minutes (which is half of 60) the minute hand covers only half a revolution. Then the distance traveled in 30 minutes is [tex]\frac{1}{2}(s) = 25.13[/tex] inches

In 20 minutes (which is one third of 60) the minute hand only travels a third of a complete revolution. Then the distance traveled in 20 minutes is [tex]\frac{1}{3}(s) = 16.76[/tex] inches

Final answer:

We calculate the distance traveled by the minute hand of a clock by using the arc length formula from geometry. Using the length of the hand as the radius and the angle covered as a fraction of 360 degrees (converted into radians), we can determine the distances for 30 and 20 minutes as 8π inches and 16/3 π inches respectively.

Explanation:

The subject of our question involves the calculation of arc lengths (distances) moved by a clock hand, an aspect of geometry. We'll be treating the minute hand of a clock as a line segment that sweeps out a circular path. The arc length formula will be utilized here, which is given by the equation L = rθ, where L is the arc length, r is the length of the minute hand (as the radius), and θ is the angle covered by the minute hand.

In a span of a whole hour or 60 minutes, the minute hand completes a full 360° circle. So, for 30 minutes, it covers half the circle which equates to 180°. This degree measure needs to be converted to radians because our formula uses radian measure. 180° equals π radians.

With r = 8 inches and θ = π, we substitute these values into our formula to get L = 8π inches for 30 minutes.

The same concept applies for 20 minutes. In this case, the hand covers a third of the circle which is (360/3)=120°, this is (2/3)π in radian. Substituting r = 8 inches and θ = (2/3)π into our formula, we get L = 16/3 π inches for 20 minutes.

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea-level, as a function of time is given by h ( t ) = − 4.9t^2 + 202t + 318 .

Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?

The rocket splashes down after____seconds.

How high above sea-level does the rocket get at its peak?

The rocket peaks at____meters above sea-level

Answers

Answer:

The rocket splashes down after 43 seconds.

The rocket peaks at 2400. meters above sea-level.

Step-by-step explanation: For the time taken before the splash

Step 1

We realise that the rocket will hit the ground when our function [tex]h(t)=0[/tex] , i.e [tex]-4.9t^2+202t+318=0.[/tex]

Step 2

Use the quadratic formula to solve for the time. For the general quadratic equation [tex]at^2+bt+c=0[/tex], the general solution to the equation is

[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a} .[/tex]

In our case, the quadratic equation [tex]h(t)=-4.9t^2+202t+318=0[/tex] has a solution

[tex]t=\frac{-202\pm\sqrt{202^2-4((-4.9)(318))}}{2(-4.9)} \\t=-1.52,t=42.74.[/tex]

Step 3

In this step we pick the value of [tex]t[/tex] that makes physical sense. Since the NASA team launced the rocket at [tex]t=0[/tex], the rocket reaches the bottom when [tex]t=42.74[/tex]. This can be rounded up to [tex]43[/tex] seconds.

For the maximum height of the rocket above sea level

Step 1

The first step is to realist that since the coefficient of the quadratic term is negative, the graph of this function will face downwards. From this we can gather that the maximum value of this function occurs at the vertex.

Step 2

In this step we calculate the t coordinate of the of the vertex of this function. For any quadratic equation [tex]h(t)=at^2+bt+c[/tex] , the vertex occurs when ,

[tex]t=-\frac{b}{2a}.[/tex]

For the equation [tex]h(t)=-4.9t^2+202t+318[/tex] , the vertex occurs when ,

[tex]t=-\frac{202}{2(-4.9)}=20.61.[/tex]

Step 3

We substitute the value of [tex]t[/tex] from step 2 above into [tex]h(t)[/tex] to get the maximum value of this function.  This calculation is shown below,

[tex]h(20.61)=-4.9(20.61)^2+202(20.61)+318=2399.84m.[/tex]

This can be rounded up to 2400m.

JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake?

Answers

JJ should leave $1.20 as the tip.

The total of JJ’s meal was $8.

$5.50 + $2.50 = $8.00

To find the tip, you need to know what 15% of $8 is. That is done by multiplying 15% and the total of JJ’s meal. Change the percent to a decimal by moving the decimal point, two places to the left.

0.15 • $8.00 = $1.2, but more known as $1.20.
Final answer:

The total cost of the meal is $8. A 15% tip on this amount is $1.20.

Explanation:

The total cost of the meal is the cost of the cheeseburger ($5.50) plus the cost of the milkshake ($2.50), giving a total of $8. To calculate a 15% tip, we multiply the total cost by 0.15. So, JJ should leave a tip of $8 * 0.15 = $1.20.

Answers

Answer:

Jess's bill amount without tip: B

Jess's tip amount: 0.21B.

Jess's total bill amount: [tex]B+0.21B[/tex]

Step-by-step explanation:

We have been given that Jess has dinner at a restaurant. The dinner bill is B dollars. So the Jess's bill amount without tip will be B dollars.

We are told that she pays a 21% tip. Let us find 21% tip of dinner bill (B).  

[tex]\text{Jess's tip amount}=\frac{21}{100}*B[/tex]

[tex]\text{Jess's tip amoun}=0.21B[/tex]

Therefore, Jess's tip amount will be [tex]0.21B[/tex].  

Let us find total amount of Jess's bill by adding bill amount (0.21B) to the Jess's bill amount without tip (B).

[tex]\text{Total amount of Jess's bill}=B+0.21B[/tex]

Therefore, the total amount of Jess's bill will be [tex]B+0.21B[/tex].



Jess's bill without tip is B, her tip amount is 0.21B, and her total bill including a 21% tip is 1.21B.

When Jess has dinner at a restaurant with a dinner bill of B dollars and decides to pay a 21% tip, you can calculate her expenditures in the following manner:

Jess's bill amount without tip: This is simply the original amount of the bill, which is B dollars.Jess's tip amount: To calculate the tip, you convert the percentage to a decimal by dividing by 100 (21% = 0.21) and then multiply by the bill amount. The expression for the tip amount is 0.21B.Jess's total amount: To find the total amount Jess pays, you add the original bill amount to the tip amount, resulting in the expression B + 0.21B. This simplifies to 1.21B because you combine like terms.

Therefore, the expressions that match their correct meanings for Jess are as follows: Jess's bill amount without tip: B, Jess's tip amount: 0.21B, Jess's total amount: 1.21B.

A postman has to deliver 450 letters . The number of letters delivered in one street is twice the number delivired in other . If he is left with 120 letters , then find the number of letters deliveired in the first street

Answers

Answer:

The number of letters in the one street be 220 .

Step-by-step explanation:

As given

A postman has to deliver 450 letters .

The number of letters delivered in one street is twice the number delivered in other .

Let us assume that the number of letters delivered in second street be x.

Let us assume that the number of letters delivered in first street = 2x

As given

If he is left with 120 letters .

Thus

The number of letter delivered in one and other street  = 450 - 120

                                                                                            = 330

Than the equation becomes

x + 2x = 330

3x = 330

[tex]x = \frac{330}{3}[/tex]

x = 110

The number of letters in the one street = 2 × 110

                                                                  = 220

Therefore the number of letters delivered in first street be 220.


Final answer:

The postman delivered 110 letters to the first street and 220 letters to the second street

Explanation:

This is a problem of simple algebra where you have to solve for unknowns. We know the postman has 450 letters in total, and 120 are left after delivering to two streets. So, the total number of letters he delivered is 450 - 120 = 330 letters.

Let’s say the number of letters delivered in one street is x. Therefore, the number of letters delivered in the other street would be 2x because it's twice the number delivered in the first street.

Since the postman delivered all 330 letters in two streets, the equation becomes x + 2x = 330. Simplifying this we get 3x = 330. Then, solve for x by dividing both sides by 3, so x = 330 / 3 = 110.

Therefore, the number of letters delivered in the first street is x = 110, and in the second street it's 2x = 2*110 = 220.

Let x = 2. Evaluate the expression. x  +  4/3x

Answers

When x = 2, the expression evaluates to -442/3.

To evaluate the expression when x = 2, we substitute 2 for x in the expression:

x + 4/(3x) - 150

Now, we plug in the value of x:

2 + 4/(3 * 2) - 150

First, we simplify the denominator:

2 + 4/6 - 150

Now, simplify the fraction:

2 + 2/3 - 150

Next, we need to find a common denominator, which in this case is 3:

(3 * 2)/3 + 2/3 - 150

Now, add the fractions with the common denominator:

(6/3) + (2/3) - 150

Combine the fractions:

(6 + 2)/3 - 150

Now, perform the addition in the numerator:

8/3 - 150

To subtract a fraction from a whole number, we need a common denominator. In this case, it's 3:

(8/3) - (150 * 3/3)

Now, subtract:

8/3 - 450/3

Subtract the numerators:

(8 - 450)/3

Now, perform the subtraction in the numerator:

-442/3

So, when x = 2, the value of the expression x + 4/(3x) - 150 is -442/3.

Answer:

(A)

[tex]C_n=3+2n[/tex]

(B)

[tex]C_1_0=23[/tex]

Step-by-step explanation:

(A)

we are given

[tex]C_n_+_1=C_n+2[/tex]

[tex]C_1=5[/tex]

Firstly, we will find few terms

[tex]C_2=C_1+2[/tex]

[tex]C_2=5+2[/tex]

[tex]C_2=7[/tex]

[tex]C_3=C_2+2[/tex]

[tex]C_3=7+2[/tex]

[tex]C_3=9[/tex]

[tex]C_4=C_3+2[/tex]

[tex]C_4=9+2[/tex]

[tex]C_4=11[/tex]

so, we will get terms as

5, 7 , 9 , 11

we can see that this is arithematic sequence

First term =5

common difference =d=7-5=2

now, we can use nth term formula

[tex]C_n=C_1+(n-1)d[/tex]

now, we can plug values

[tex]C_n=5+2(n-1)[/tex]

[tex]C_n=5+2n-2[/tex]

[tex]C_n=3+2n[/tex]

(B)

we can plug n=10

[tex]C_1_0=3+2\times 10[/tex]

[tex]C_1_0=23[/tex]

A father is 60 yrs old son is half his age .How old was the boy when his father was four times his age

Answers

let f be the fathers age and let s be the sons age

f = 60 s = 30
when f = 45
s = 15 which is only a third if his fathers age

when f = 40
s = 10 which is a quarter of his fathers age

therefore when his father was 4 times his age, the son was 10
Let F be the father's age, let S be the son's age
when: F = 60,
S = F/2 = 60/2 = 30

this means S = F-30

this means:
F/4 = F -30
F = 4F - 120
-3F = -120
F = 40

If the boy was 4 times less his father's age,
at this instance:
S = 40/4 = 10

therefore the son was 10 years old, the father was 40

Read the passage from chapter 17 of The Prince. Among the wonderful deeds of Hannibal this one is enumerated: that having led an enormous army, composed of many various races of men, to fight in foreign lands, no dissensions arose either among them or against the prince, whether in his bad or in his good fortune. This arose from nothing else than his inhuman cruelty, which, with his boundless valour, made him revered and terrible in the sight of his soldiers, but without that cruelty, his other virtues were not sufficient to produce this effect. How does the authors diction affect the tone in this passage? Words like inhuman, cruelty, and terrible support a tone of fear. Words like wonderful, boundless, valour, revered, and virtues support a tone of admiration. Words like sufficient, enumerated, virtues, and dissensions support a critical tone.
