Answer:

$2157.85

Step-by-step explanation

All you would do is every year find eight percent of each number then carry it on the next year so on and so forth until year

How you would find 8% of a number is:

Multiply your current number by .08 and what ever that answer is add it onto the first number and that would give you one year

Do number 27 please

Answer:

To find the volume of this figure, we must find the base area(pentagon) and multiply it by the figure's height.

Formula for area of a pentagon:-

A = 1/2 x p x a

Where 'p' represents the perimeter, and 'a' represents the apothem.

First, let's figure out the perimeter of the base pentagon.

One side of this pentagon is 10cm, and there are 5 side lengths of 10cm to this pentagon. So it'll result in (5 x 10) = <u>50cm</u> altogether.

The apothem is given, <u>6.9cm</u>.

So, we plug these into our formula:-

A = 1/2 x p x a

A = 1/2 x 50 x 6.9

A = 50/2 x 6.9

A = 25 x 6.9

A = <u>172.5cm</u>, is the area of the pentagon.

Now we find the height of this figure and multiply it by the base area we've found(pentagon).

Our height is 17cm.

172.5(17)

= <u>2,932.5 cubic centimetres</u>, is our volume.
