Step-by-step explanation:

14.50 - 4.35 - 5.25= 4.9

Mai has $4.90

Step-by-step explanation:

14.50 - 4.35 = 10.15

10.15 - 5.25 = 4.9

Mai has $4.90

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

f(x) has value 150 at x= 0

and 0 at x= 3

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