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

A company has 29900 employees in one country. If this represent 18.3% of the company’s employees, how many employees does it hav
mario62 [17]

Answer:

About 163 388 employees

Step-by-step explanation:

Let total number of employees in the company be represented by x. Thus:

18.3\% \: of \: x = 29900

18.3\% \:x \:  = 29900

\frac{18.3}{100}x = 29900

0.183x = 29900

Divide through by 0.183

\frac{0.183x}{0.183}  =  \frac{29900}{0.183}

x = 163387.9

x = 163388 \: to \: nearest \: whole \: number

The total number of employees in one country is about 163388
