Answer:

π/4

Step-by-step explanation:

The area of the circle is A = π(2x)^2 = 4πx².

The length of one side of the square is 2(2x), or 4x, so the area of the square is A = 16x².

The ratio of the area of the circle to the area of the square is

              4πx²

ratio = -------------   and this reduces to ratio = π/4.

              16x²

weeeeeb [17]

Answer:

x = number of days

y = number of remaining photos saved to her camera roll.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of pictures saved in the camera roll (2,500) minus the amount of photos that she deletes per day (50) multiplied by the number of days (x) must be equal to the number of photos remaining.

y =2,500- 50x

The variables are x and y.

Where x is the number of days and y is the number of remaining photos.
