Answer:

88 u²

Step-by-step explanation:

The formula for the area of a trapezoid is:

A = $\frac{1}{2}h(b_{1}+b_{2})$ where h = height and $b_{1}$ =length of one base and $b_{2}$ =length of the other base.

Given the measurements in the diagram:

h = 4 units

$b_{1}$ = 17 units

$b_{2}$ = 17 + 5 + 5 = 27 units

Plug them into the equation: A = $\frac{1}{2}$ (4)(17 + 27) = 88 units²

An employee put $5,000 in a retirement account that offers 9% interest compounded annually. The employee makes no additional dep

sergiy2304 [10]

Answer:

$2,693.12 will the employee have eared at the end of 5 years.

Step-by-step explanation:

The formula of compound interest:

$A=P(1+r)^n$

$I$ = A-P

A= The amount in the account after n years

P= Principal

r= rate of interest annually

n= time in years.

An employee put $5,000 in retirement account that offer 9% interest compounded annually.

Here P=$5,000, r=9%=0.09, n= 5 years

$A=5,000(1+0.09)^5$

=$7,693.12

The interest = A-P

=$(7,693.12-5,000)

=$2,693.12

$2,693.12 will the employee have eared at the end of 5 years.

A gallery owner purchased a very old painting for 3000 dollars. The painting sold for 325 percent increase in price. What is the

GrogVix [38]

Answer:

$12,750

Step-by-step explanation:

The price at purchase = 3000 dollars

Sale = 325 percent increase in purchase price.

325% = 3.25

3.25x3000 = 9750 dollars

So, at 325 percent increase in price, this painting sold for $9750.

The retail price of this painting =

Price at purchase + price during sale

= 3000 + 9750

= $12,750

Therefore the retail price is equal to $12,750

The right rectangular prism is made up of 48 cubes. Each cube has an edge length of inch. What is the volume of this prism?

Gnesinka [82]

Given:

The right rectangular prism is made up of 48 cubes.
Each cube has an edge length of 1/4 inch.

$~$

To Find:

What is the volume of this prism?

$~$

Solution:

$~$

<u>Using formula: </u>

$~$

$\sf \pmb {Volume \: of \: cube = {(side)}^{3} }$

$~$

Substituting values in the formula:

$~$

$\sf \longrightarrow \dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4}$

$\sf \longrightarrow \dfrac{1}{64} \: {inch}^{3}$

$~$

Now,

Volume of 48 such cubes = Volume of 1 cube × 48 cubes

$~$

$\sf \longrightarrow \dfrac{1}{64} \times 48$

$\sf \longrightarrow \dfrac{48}{64}$

$\sf \longrightarrow \dfrac{3}{4} \: {inch}^{3}$

$~$

Hence,

Volume of prism is <u>3/4 inch^3</u>
