Answer:

The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Step-by-step explanation:

First step is to find the area of the circle

A = pi * r^2

A = pi * 6^2

A = 36* pi

We are missing 90  degrees of the circle  or 90 out of 360.

That means we keep 360 - 90 = 270  or 270/360

The fraction we are keeping simplifies to 3/4  (divide top and bottom by 90)

Multiply the area by the fraction that we kept.

36 pi * 3/4 = 27 * pi


The exact answer is 27 * pi

or the approximate answer is 27 * 3.14 = 84.78

Chole wants to build a storage container in the shape of a cube to hold 15.625 cubic meters of hay for her horse. Slove the equation 15.625 =s3 find the length of oneside of the container

Answers

Answer:

The length of each side is 2.5 m

Step-by-step explanation:

A cube has a volume of 15.625 m^3 of hay

We want to find the length of one side

V= s^3 where s is the length of one side

15.625 = s^3

Take the cube root of each side

15.625 ^ (1/3) = s^3 ^(1/3)

15.625 ^ (1/3) = s

2.5 = s

The length of each side is 2.5 m

The expression in complete factored form is (3c - 4)(c + 3)

What is a complete factored form expression ?

A complete factored form is a form of expressing a complex polynomial expression as the products of factors of the polynomial. If we equate the complete factored expression with zero, we get the solutions of the polynomial expression.

Solving the given expression in complete factored form -

The expression given is [tex]3c(c + 3) - 4(c + 3)[/tex]

Expanding the given expression  [tex]3c^{2} + 9c - 4c - 12[/tex]

= [tex]3c^{2} + 5c - 12[/tex]

= [tex]3c^{2} + 9c - 4c - 12[/tex]

= [tex]3c(c + 3) - 4(c + 3)[/tex]

= [tex](3c - 4)(c + 3)[/tex]

Thus the expression in complete factored form is (3c - 4)(c + 3)

The slope of the line below is 2. Write a point-slope equation of the line using the coordinates of the labeled point( 3,10)

Answers

Answer:

Point slope form of the line is  [tex]y-10=2(x-3)[/tex]


Step-by-step explanation:

The point-slope form of a line is given as:

[tex]y-y_1=m(x-x_1)[/tex]

Where,

[tex]m[/tex] is the slope, and [tex](x_1,y_1)[/tex] is the x point and y point respectively

The question tells us the slope is 2, hence [tex]m=2[/tex] and the point given is (3,10) which means [tex]x_1=3[/tex] and [tex]y_1=10[/tex]. Substituting these values into the point slope form of a line gives us:

(x, y ) = (5, 4 )

Step-by-step explanation:

given the 2 equations

3x - 2y = 7 → (1)

- 3x + 5y = 5 → (2)

adding the 2 equations term by term will eliminate x

(3x - 3x) + (- 2y + 5y ) = (7 + 5 )

0 + 3y = 12

3y = 12 ( divide both sides by 3 )

y = 4

substitute y = 4 in either of the 2 equations and solve for x

(1 ) : 3x - 8 = 7 ( add 8 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

solution is (5 , 4 )

Given: m∠1 = 140°, find m∠6.
A) 40°
B) 50°
C) 90°
D) 140°

Answers

Answer:

The answer is A

Step-by-step explanation:

When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.

Answer:

40°, A

Step-by-step explanation:

What are we going to do to figure out measure 6?

First of all, we know that measure 5 and measure 6 are equal to 180 degrees.

Second of all, we know that measure 1 and measure five are corresponding angles, which means they are congruent. If measure one is 140 degrees, measure 5 would also be 140 degrees.

So we know that measure 5 and measure 6 are equal to 180 degrees. We can now make an equation...

Let x = measure 6

140° + x = 180°           x = 40°

Gabe needs 30 liters of the 50% solution

Gabe needs 30 liters of the 70% solution

Both answers are 30

==================================

Explanation:

We have two beakers, each of which we don't know how much is inside. Let's call this x and y

x = amount of liquid in the first beaker (water+acid)

y = amount of liquid in the second beaker (water+acid)

We're told that the beakers have a 50% solution and a 70% solution of acid. This means that the first beaker has 0.5*x liters of pure acid, and the second beaker has 0.7*y liters of pure acid. In total, there is 0.5x+0.7y liters of pure acid when we combine the two beakers. This is out of x+y = 60 liters total, which we can solve for y to get y = 60-x. We will use y = 60-x later on when it comes to the substitution step

We can divide the total amount of pure acid (0.5x+0.7y liters) over the total amount of solution (x+y = 60) to get the following

(0.5x+0.7y)/(x+y) = (0.5x+0.7y)/60

We want this to be equal to 0.6 because Gabe wants a 60% solution when everything is said and done, so

(0.5x+0.7y)/60 = 0.60

0.5x+0.7y = 0.60*60 .... multiply both sides by 60

0.5x+0.7y = 36

0.5x+0.7( y ) = 36

0.5x+0.7(60-x) = 36 ........ replace y with 60-x (substitution step)

0.5x+0.7(60)+0.7(-x) = 36 .... distribute

0.5x+42-0.7x = 36

-0.2x+42 = 36

-0.2x = 36-42 .... subtract 42 from both sides

-0.2x = -6

x = -6/(-0.2) .... divide both sides by -0.2

x = 30

He needs 30 liters of the 50% solution

Use this x value to find y

y = 60-x

y = 60-30

y = 30

So he needs 30 liters of the 70% solution


how do i prove am + am = AB

Answers

Statement 1: AM is the midpoint of AB

Reason 1: Given

Statement 2: AM+MB = AB

Reason 2: Segment Addition Postulate

Further explanation: Basically this idea is where you can break up the line segment into smaller pieces, or glue smaller segments to form a larger segment.

=====================================

Statement 3: AM = MB

Reason 3: Definition of midpoint

Further explanation: The midpoint cuts a line segment in half. The two smaller pieces AM and MB are congruent (ie equal in length)

=====================================

Statement 4: AM + AM = AB

Reason 4: Substitution

Further explanation: We replace the MB in statement 2 with AM. This replacement is possible because of the equation AM = MB in statement 3.

A 12-ounce bottle of soda costs $3.60. If the unit price remains the same how much would a 20-ounce bottle of soda cost?

A) $3.00
B) $5.50
C) $6.00
D) $6.50

Answers

For this, simply set up a proportion. If 12 oz. costs $3.60, then this means $3.60 per oz, or [tex]\frac{3.6}{12}[/tex]. Now letś make a proportion for 20 oz. Itś asking for how much it would cost if the unit price was the same, which means that the two should have a similar ratio. Because we don´t know how much it costs yet, this means x dollars for a 20 oz. bottle, or [tex]\frac{x}{20}[/tex]. I´ve already mentioned that they two are proportional, so write [tex]\frac{3.6}{12} = \frac{x}{20}[/tex].

To solve, cross multiply.

⇒[tex]12*x=3.6*20[/tex]

⇒[tex]12x=72[/tex]

Isolate variable x.

⇒[tex]\frac{12x}{12} = \frac{72}{12}[/tex]

⇒ x = 6: $6.00 for 20 ounces of soda.

Checking your work:

3.6/12 = 0.3

6/20 = 0.3

This means that theyŕe proportional, and that your answer is correct. Hope this was helpful.

Five added to twice Jeff’s age is the same as 3 times his age minus 2. How old is Jeff

Answers

Answer:

21

Step-by-step explanation:


To find Jeff's age, we set up an algebraic equation based on the problem given. By isolating the variable and solving the equation, we determine that Jeff is 7 years old.

The problem presented is a basic algebraic equation that can be translated to: 5 + 2 * Jeff's age = 3 * Jeff's age - 2. To solve for Jeff's age, we follow these steps:

First, let's define Jeff's age as the variable x. So we can rewrite the equation as 5 + 2x = 3x - 2.Next, we want to get all the x terms on one side and the constant terms on the other to isolate x. We can do this by subtracting 2x from both sides of the equation, which gives us: 5 = x - 2.Finally, by adding 2 to both sides of the equation, we get Jeff's age, x = 7.

Jeff is 7 years old.

Mr. Willis is building a new dock at his lake house that will be 35 feet long. If the blueprints show the dock as 16 inches long, what scale was used to create the blueprint?

Answers

Answer:

1:26.25

Step-by-step explanation:

Scale = 16 in:35 ft

Convert 35 ft to inches

1 ft = 12 in

35 × 12/1 = 420 in

Scale = 16 in:420 in     Divide each term by 16

Scale =      1:26.25

The scale used to create the blueprint for Mr. Willis's dock is 1:26.25, meaning that each inch on the blueprint represents 26.25 inches of the actual dock.

The actual dock is 35 feet long, and there are 12 inches in a foot, so the dock is 35 feet × 12 inches/foot = 420 inches long. The blueprint shows the dock as 16 inches long. Therefore, we use the scale factor formula:

scale factor = blueprint length / actual length

The scale factor is 16 inches / 420 inches, which simplifies to 1/26.25. Thus, the blueprint is drawn at a scale of 1:26.25, meaning that 1 inch on the blueprint represents 26.25 inches in the actual size.
