HELP PLEASE ANSWER FULL QUESTION

Answer:

22 pi ft

Step-by-step explanation:

We can use the area to find the radius

A = pi r^2

121 pi = pi r^2

Divide each side by pi

121 = r^2

Take the square root

sqrt(121) = sqrt(r^2)

11= r

Now we need to find the circumference

C = 2*pi*r

C = 2* pi *11

C = 22 pi ft

Answer:

1. Use area to find radius.

  A =  π r^2

  121 π = π r^2

2. Divide each side by π.

   121 = r^2

3. Take in the square root .

    [tex]\sqrt{121} = \sqrt{r^{2} }[/tex]

   11 = r

4. Find the circumference .

   C = 2 × π × r

   C = 2 × π × 11

    C = 22 π ft

Answer:

37

Step-by-step explanation:

let’s say peter’s number is x

(x-12)(-7) = -175

-7x + 84 = -175

-7x = -259

x = 259/7

x = 37

Answer:

The number is 37.

Step-by-step explanation:

-175 ÷ -7 = 25

25 + 12 = 37

You have to work backwards from -175 by doing the reverse of what peter did to get the original number.

Answer:

54%

Step-by-step explanation:

We know Chick-fil-A served 50 sodas in all, 27 of which were regular. The fractional form of this is 27/50. Now, we can convert this to a fraction with a denominator with 100, then a percentage. 27/50 is equal to 54/100.

54/100 is 54%

Answer:

is 54.the max is 100 percent.the percentage of regular sodas is 54 percent.you do this by timing 50 and 27 by 2 to get 100 and 54.

Answer:

use division

Step-by-step explanation:

this question is pretty simple, all you need to do is the opposite of multiplication, which is........division.

so divide 28 by 8 = 3.5

so it prints 3.5 (3 and a half) pages per minute.

Answer:

167 adult tickets were sold

35 children tickets were sold

Step-by-step explanation:

Let the number of adult tickets be x

Let the number of children tickets be y

Total number of each ticket sold;

x + y = 202 equation 1

Total cost of the tickets

10x + 6y = 1708 equation 2

Let

x= 202 - y equation 3

Substitute 3 into 2

10(202 - y) + y = 1708

2020 - 10y + y = 1708

-9y = 1708 - 2020

-9y = -312

y= 35

Substitute y =35 into 1

x + 35 =202

x= 202 - 35

x= 167

Therefore;

167 adult tickets were sold

35 children tickets were sold

Answer:

B. Graph 2 represents a proportional relationship, but graph 1 does not.

Step-by-step explanation:

All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.

Examples (all found in Graph 2):

15/3 = 5

10/2 = 5

5/1 = 5

Answer:

The value of c is 1/2

Step-by-step explanation:

We have to find the value of c that completes the square  [tex]x^2-x+c[/tex]

So, completing square is of form: [tex]a^2-2ab+b^2=(a-b)^2[/tex]

In the question given the value c can be found by breaking the middle term. we are given -x while the general formula is 2ab for middle term so, our c = 1/2 i.e 2(x)(1/2) we get x so, solving:

[tex]x^2-x+c\\=x^2-2(x)(\frac{1}{2})+(\frac{1}{2})^2-(\frac{1}{2})^2\\=(x-\frac{1}{2})^2-(\frac{1}{2})^2[/tex]

The value of c is 1/2

Answer: 4 quarts.

Step-by-step explanation:

Given data:

Amount of dry ingredients = 5 quarts.

Amount of water in the mixture = 2 quarts.

Solution:

Let’s a represent the amount of dry ingredients.

Let b represent the amount of water

For first Batch

a/b = 5/2.

b = 2/5a ....... equation 1

For second Batch

a= 10

substitute a into equation 1 to solve for b

b = 2/5(10)

b = 4.

The ratio for batch b = 10/4.

Zahara needs to add 4 quarts of water to the mixture.

Answer:4 quarts!

all u have to do is find two point and count down and to the side basically find the distance of those two points to find the slope.

Answer:

3/5

Step-by-step explanation:

From what I can see two points of the line are (0,1) and (5,4) so you can just count and do rise/run which is y/x or the formula which is like y^2-y^1/x^2-x^1 they both get the same answer which is 3/5

If you plug the numbers into the formula it gives you 4-1/5-0 which is 3/5

Step-by-step explanation:

80$ is original price so 100%

markup by 35% make price 135%

crossmultiplication

ans=108

Based on the cost of the camera and the percentage markup, the selling price of the camera is $108.

The camera's selling price is 35% more than its cost price. That 35% is:

= 80 x 35%

= $28

The selling price of the camera is therefore:

= Cost of camera + Increase

= 80 + 28

= $108

In conclusion, the camera is being sold for $108.

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

[tex]f(x)=\frac{1}{3} -\frac{1}{21} x[/tex]

Switching the positions of the x and f(x) values...

[tex]x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\[/tex]

Note: That f(x)^-1 is the proper notation for inverse functions.

[tex]x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7[/tex]

There you go!
