Answer:
A/B = 0.125
Step-by-step explanation:
Givens
r for Sphere A = 4
r for Sphere B = 8
Solution
Volume A = 4/3 pi r^3
r = 4
Volume A = 4/3 pi 4^3
Volume A = 4/3 pi 64
Note: there is no point in expanding the result. 4/3 and pi are going to cancel out when you set up the volume formula
Volume B = 4/3 pi * r^3
r = 8
Volume B = 4/3 pi * 8^3
Volume B = 4/3 pi * 512
Ratio A to B = 4/3 pi * 64 / 4/3 * pi * 512 Cancel 4/3 pi
Ratio A to B = 64/512
Ratio A to B = 1/8
Ratio A to B = 0.125
P-4 = -9 + p
Because there is the same quantity of the letter p on each side of the equal sign there is no solution to this problem.
Answer: no solution
The wording "earns 8% interest each year" does not make it clear whether the savings account interest is compounded. (It usually is in real life, but not always in math problems.) The graphical solution shows both simple interest and interest compounded annually.
Simple interest: the balances will both be $2941.18 after 5.88 years.
Compound interest: the balances will both be $3111.06 after 5.74 years.
