Vol=area x Height

length= 3
breadth= X
Height = 2

area must = half of 42 because to get the volume of 42cm cubed, you had to times the area by 2 so

42 devided by 2 is 21 so to find the length you myst do 21 devided by 3 which is 7

so the missing length is 7cm

The population of a town increased by 15% in 2016, and decreased by 5% in 2017. If the population of the town was 60,000 in the

Answer:

The population of the town at the end of 2017 was 65,550.

Step-by-step explanation:

The population of the town was 60,000 in the beginning of 2016.

In 2016, the total population is increased by 15%.

$60,000\times\frac{15}{100}=9000$

Therefore the population is increased by 9000 and the population of the town at the end of 2016 was

$60,000+9000=69,000$

In 2017, the total population is decreased by 5%.

$69,000\times\frac{5}{100}=3450$

Therefore the population is decreased by 3450 and the population of the town at the end of 2017 was

$69,000-3450=65,500$

Therefore the population of the town at the end of 2017 was 65,550.
