Answer:
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec
Step-by-step explanation:
Volume V = length l^3
V = x^3
Differentiating both sides;
dV/dt = 3x^2 dv/dt
Given;
x = 10 in
dx/dt = 0.5 in/sec
dV/dt = 3×10^2 × 0.5 = 150 in^3/sec
the volume of the cube is increasing at 150in^3/sec

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5
Step-by-step explanation:
Given: Breanna saves 75% of her earnings to buy new school clothes.
Earnings for Breanna = $ 750
The amount of money she saves to buy clothes = 75% of 750
= 0.75 x 750 [75%= 0.75]
= $ 562.5
Hence, the best estimate for the amount of money she saves to buy clothes = $ 562.5
