By the larger circle, they mean the red area plus the white area. We now must calculate the area of both.

Small circle area (white area)= PI * 4.02^2 = 50.77 square inches

TOTAL Circle Area (red and white) = PI * 8.01 *8.01 = 201.56

(Red area)= PI * 8.01^2 -50.77

(Red area)= 201.56 -50.77 = 150.79

A point chosen in the TOTAL 201.5648988136 square inch area has the probability of being in the read area=

red area / TOTAL area = 150.79 / 201.56

probability = .748 = 74.8% of the time.

A. x = 2, y =6<br> B. x = 2, y =3<br> C. x =-2, y =3<br> D. x = -3, y =2
AlekseyPX

Answer:

The correct answer is A) x = 2 and y = 6

Step-by-step explanation:

In order to find the answer, we need to set the hypotenuses equal to each other. Then we can solve for y to get the equation.

y - 1 = x + 3

y = x + 4

Now we can do the same with the leg lengths.

y - 3 = 2x - 1

y = 2x + 2

Now that we have two equations, we can set them equal to each other to get the x value.

x + 4 = 2x + 2

4 = x + 2

2 = x

Now that we have x, we can plug it into any equation to get the y value.

y = x + 4

y = 2 + 4

y = 6

1. A-Tunes requires a membership fee of $12 a month and $1 for each download.
matrenka [14]
<h3>Answer:</h3>

After 16 downloads the charges will equal each other.

<h3>Step-by-step explanation:</h3>

First set up an equation

x = Downloads

12 + 1x = 5 + 1.5x

Solve

12 + 1x = 5 + 1.5x <- Rewrite your equation

-5          -5            <- Subtract 5 from both sides

 8 + 1x = 1.5x       <- Simplify

      -1x    -1x         <- Subtract 1 from both sides

        8 = 0.5x      <- Simplify

        8 = 1/2x       <- Convert 0.5 to a fraction to make the next step easier

       16 = x            <- Multiply both sides by 2 to divide by

                                 a fraction
