Atown has a population of 8000 in groves at 4.5% every year to the nearest year how long will it be until the population will reach 22,500

It takes 10 years approximately for the population to reach 22,500

Step-by-step explanation:

Given:

Initial population  =  8000

Population growth rate  4.5 %

Future population = 22500

To Find:

Time taken to reach a population of  22500

Solution:

The population growth can be identified by using

where

N is  future popluation

is the initial population

t is the time taken

r is the rate of the growth

Here we have to find the time t, rephrasing the formula

Substituting the values we get,

t = 9.97

t=10(approx)

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
