Answer:

width = 126 ft

Step-by-step explanation:

I'm going to assume that I am solving for width.

Area = width x length

84 = 2/3 x width

Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)

84 x 3/2 = width

width = 126 feet

38. Emily is buying some graduation pictures. She pays $25 for the sitting and $15 for each

goldfiish [28.3K]

a. She pays $100 for 5 sheets

b. 25+15x dollars for x sheets

c. 8 sheets

Step-by-step explanation:

Given

Sitting cost = $25

Per sheet picture cost = $15

Let p be the number of sheets of pictures

Then the cost can be written as a function of p

$c(p) = 25+15p$

Now,

a. How much does she pay for 5 sheets of pictures?!

Putting p = 5 in the function

$c(5) = 25 + 15(5)\\= 25+75\\=100$

She will pay $100 for 5 sheets of pictures

b. How much does she pay for "x" sheets?

Putting x in place of p

$c(x) = 25+15x$

c. How many sheets can she buy for $145?

We know the cost now, we have to find p so,

$145 = 25+15p\\145-25 = 25+15p-25\\120 = 15p$

Dividing both sides by 15

$\frac{15p}{15} = \frac{120}{15}\\p = 8$

Hence,

She can buy 8 sheets for $145

A realtor earns a 3.25% commission

dlinn [17]

Since the commission is 3.25%, we simply multiply this fraction in decimal form by x, since it will equal 10566.40:

0.0325*x=10566.40

Divide both sides by 0.0325:

x = 10566.40/0.0325

x = 325120

The house sold for $325,120

Andre has enough to fill 3500 in.3.. he decides to change the length of the step so that he will use all of the cement. What wil

Mrac [35]

Answer:

43.75 inches or 43 and 3/4 inches.

Step-by-step explanation:

Ok, thanks for the complement of information.

So, to find the volume of that step, which is a rectangular prism, we would use the simple formula:

V = length * width * height

In this case, we have the total volume (3,500 cu in), we have the width (10 inches) and we have the height (8 inches). But we need to find out the new length in order for him to use all 3,500 cu in of cement.

So, we transform the formula above into:

length = V / (width * height)

then we plug-in the numbers:

length = 3,500 / (8 x 10) = 3,500 / 80 = 43.75

So, the new length of the step would be 43.75 inches or 43 and 3/4 inches.
