A population increases 3% each year. If the city is now 5 million, what will the population be in 5 years?
Step2247 [10]
5 million x 3% = 150,000
1 Year = 5,150,000

5.15 million x 3% = 154,500
2 Years = 5,304,500

5,304,500 x 3% = 159,135
3 Years = 5,463,635

5,463,635 x 3% = 163,909.05
4 Years = 5,627,544.05

5,627,544.05 x 3% = 168,826.322
5 Years = 5,796,370.37

After 5 years, the population will be 5,796,370.37

Chris is 11 5/6 years old. Marian is 1 1/3 years younger than Chris and Jane is 1 1/4 years younger than Marian. How old is Jane
jarptica [38.1K]

Answer:

Step-by-step explanation:

chris is 11 5/6 years old

marian is 1 1/3 years younger...

(11 - 1) = 10 : (5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2)...so marian is 10 1/2

jane is 1 1/4 years younger then marian...

10 1/2 - 1 1/4...

(10 - 1) = 9 : (1/2 - 1/4 = 2/4 - 1/4 = 1/4)....so Jane is 9 1/4 years <==

The softball in the mitt is 5.2 inches in diameter. What is its volume?
lesya692 [45]

Answer: 72.9 in^3

Step-by-step explanation:

The softball is a sphere, and we know that the volume of a sphere is:

V = (4/3)*pi*r^3

where pi = 3.14 and r is the radius.

We also know that the radius is half the diameter, and the diameter is 5.2 in

r = 5.2in/2 = 2.6in

Then the volume is:

V = (4/3)*pi*(2.6in)^3 = 72.9 in^3
