Find the surface area of the inside of the white study station below

  the selected answer choice is correct

Step-by-step explanation:

If flattened, it would be a rectangle 1 1/2 feet high by (1 1/2 + 2 + 1 1/2) = 5 ft long. The area of that is ...

  (1.5 ft)(5 ft) = 7.5 ft^2

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

11

step-by-step explanation:

32.50-7.50=25

225/25=11
