Answer:The dependency ratio is an age-population ratio of those typically not in the labor force and those typically in the labor force. It is used to measure the pressure on the productive population
Step-by-step explanation:
Price, when purchased online: 1.30($160)
Price, when purchased at superstore: 1.40($160)
Difference in prices: 1.40($160) - 1.30($160) = 0.10($160) = $16
A higher markup brings a higher retail price.
volume = 4/3 x PI x r^3
r = 10/2 =5
V = 4/3 x 3.14 x 5^3 = 523.333
523.3 cubic inches
Ok this is the answer to this question 2(x+1)
