What is the approximate percent increase when the population of a town increases from 12,089 to 15,025? round the population amounts to the nearest thousand to find an estimate of the percent increase.
1 the percent increase is 10%.
2 the percent increase is 25%.
3 the percent increase is 33%.
4 the percent increase is 80%.

Percent increase, population, increase, number thousand, rule of three

For this case we must find an estimate of the percentage increase of a population that increased from 12,089 to 15,025. For this we must round the population to the nearest thousand.

So:

12,089 can be rounded to the nearest thousand as 12,000

15,025 can be rounded to the nearest thousand as 15,000

By making a rule of three we have:

12000 --------> 100%

15000 --------> x

Where "x" represents the percentage of the new population.

To know the percentage increase we subtract:

So, The percent increase is 25%.

Option B

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
