Answer:

Susan worked 22 hours and 30 minutes.

Step-by-step explanation:

You can solve this using either a proportion or just simple calculator inputs! I used the inputs :

191.25/8.50 = 22.5

but, if you wanted to use a proportion :

8.50/1 = 191.25/x

8.50x = 191.25(1)

8.50x/8.50 = 191.25/8.50

x = 22.5

and the .5 means half of an hour, which is 30 minutes, so, Susan worked for 22 hours and 30 minutes that week :)

For the data in the table, write an equation for the direct variation.

melisa1 [442]

The equation of direct variation is,

$\begin{gathered} y=kx \\ k=\frac{y}{x} \end{gathered}$

Substitute the values of y and x.

$\begin{gathered} k=\frac{5.4}{4} \\ k=1.35 \end{gathered}$

So, the obtained equation will be y=1.35(x).

Let's check with the values of x.

1) If x=4

$\begin{gathered} y=1.35x \\ y=1.35(4) \\ y=5.4 \end{gathered}$

2) If x=2

$\begin{gathered} y=1.35x \\ y=1.35(2) \\ y=2.7 \end{gathered}$

3) If x=-2

0.035x+0.045x=427.50
0.08x=427.50
x=427.50/0.08
x=5343.75

x+x+1500=5343.75
2x=5343.75-1500
2x=3843.75
x=1921.88 first
1921.88+1500=3421.88 second

What is the area of a regular pentagon with a side of 7.2 and an apothem of 7

timofeeve [1]

The area of a regular polygon is given by the formula which is expressed as:

area = (½)(apothem)(perimeter)

We calculate as follows:

area = (½)(7)(7.2 x 5)
area = 126 square units

Hope this answers the question.

Ramon earns $1,735 each month and pays $53.10 on electricity. To the nearest tenth of a percent, what perfect of ramons earnings

Alenkinab [10]

Answer:

$\boxed{3.1 \, \%}$

Step-by-step explanation:

The formula for calculating percentage is

$\text{Percentage} = \dfrac{\text{Part}}{\text{Whole}} \times 100 \, \%$

The "part" is the electricity payment.

The "whole" is Ramon's earnings.

$\begin{array}{rcl}\text{\% of earnings} & = & \dfrac{53.10}{1735} \times 100 \, \% \\\\& = & \mathbf{3.1 \, \%}\\\end{array}\\\boxed{\mathbf{3.1 \, \%}} \text{ of Ramon's earnings are on electricity}$
