The population of a small town is 39,668 and has been continuously declining at a 1.5% a year what will the population be in 13
anyanavicka [17]

Answer:  31, 932.74

Step-by-step explanation:

The population of the small town              =  39,668

Yearly rate of decline                                 = 1.5%

Therefore, to calculate 1.5% of 39,668       = 1.5  x 39,668

                                                                         ------------------

                                                                                  100

                                                                      =   595.02

So, the population is declining by 595.02 on yearly basis.

To ascertain what will the population would have declined to in the next 13 years,

We multiply ,                                                = 595.02 x 13

                                                                      =7,735.26

Now population in 13 years                         = 39,668 - 7,735.26

                                                                      = 31,932.74

What is hundred-seventy as a fraction.
exis [7]
Hello,

To write 170 as a fraction ,you have to write 170 as the numerator and put it over 1 for the denominator.

After that, you now multiply numerator and denominator by 10.

170 = 170/1 (x 10) = 1700/10

The answer then is:
170 as a fraction<span> equals </span><span>1700/10
</span>
Hope this helps.
