Answer:

416 yd^2

Step-by-step explanation:

The formula for the surface area of a triangular prism is

$A=2\sqrt{\frac{a+b+c}{2}(\frac{a+b+c}{2}-a)(\frac{a+b+c}{2}-b)(\frac{a+b+c}{2}-c)}+(a+b+c)h$

where h is the height (10), and a, b and c are the base sides (10, 10, 12).

A rectangular prism is 3 meters long, 4 meters wide, and has a total surface area of 94 square meters. What is its height?

inysia [295]

SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7
5=H

Felipe borrowed $8000 at a rate of 16.5%, compounded monthly. Assuming he makes no payments, how much will he owe after 7 years?

Gelneren [198K]

Answer:

$25,193.17

Explanation:

Given:

• Principal Felipe borrowed, P=$8000

• Annual Interest Rate, r=16.5%=0.165

• Compounding Period, k=12 (Monthly)

• Time, t=7 years

We want to determine how much he will owe after 7 years.

In order to carry out this calculation, use the compound interest formula below:

$A(t)=P\mleft(1+\frac{r}{k}\mright)^{tk}$

Substitute the values defined above:

$A(t)=8000\mleft(1+\frac{0.165}{12}\mright)^{12\times7}$

Finally, simplify and round to the nearest cent.

$\begin{gathered} A(t)=8000(1+0.01375)^{84} \\ =8000(1.01375)^{84} \\ =\$25,193.17 \end{gathered}$

After 7 years, Felipe will owe $25,193.17.
