y=8x can be used to find the total amount earned by Claudia.
Step-by-step explanation:
let,
x be the number of hours and y be the amount earned.
She earned $72 for 9 hours;
9x=72
Dividing both sides by 9;
Therefore she earns 8 dollars per hour.
As the amount is same, therefore,
Amount earned = Amount per hour * No. of hours
y=8x can be used to find the total amount earned by Claudia.

Answer: 38
Step-by-step explanation:
Answer:
Correct answer: C. 936π ft³
Step-by-step explanation:
The formula for the volume of a sphere is:
V = 4/3 r³ π
Let the radius of the first sphere be r₁ = 3 ft and the second r₂ = 9 ft
Increasing the volume of the sphere is equals to the difference of V₂ and V₁
ΔV = V₂ - V₁ = 4/3 r₂³ π - 4/3 r₁³ π = 4/3 π ( r₂³ - r₁³ ) = 4/3 π ( 9³ - 3³ )
ΔV = 4/3 π ( 729 - 27 ) = 4/3 π · 702 = 4 · 234 · π = 936 π ft³
ΔV = 936 π ft³
