Mackenzie has $70 in a savings account. The interest rate is 5%, compounded annually.
sladkih [1.3K]

Answer:

She will have $73.5 in 1 year

Step-by-step explanation:

She has $70 and the interest rate is 5% so we need to add 5% to the initial value

x = $70 + $70 * 5%

5% = 5/100

x = $70 + $70 * 5/100

x = $70 + $3.5

x = $73.5

She will have $73.5 in 1 year

Find the volume of the following
Nadusha1986 [10]

Given:

A prism with right triangular base.

Base of triangle = 6 ft

Height of triangle = 8 ft

Height of prism = 7

To find:

The volume of the given prism.

Solution:

The volume of prism is:

V=Bh             ...(i)

Where, B is the base area and h is the height of the prism.

In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:

B=\dfrac{1}{2}\times base\times height

B=\dfrac{1}{2}\times 6\times 8

B=\dfrac{48}{2}

B=24

Substituting B=24,\ h=7 in (i), we get

V=24\times 7

V=168

Therefore, the volume of the prism is 168 cubic ft.
