If the cost to purchase and install carpet is $4 per square foot, how much will it cost to put carpet in the family room and hal
andrey2020 [161]

The first step is to section the given daigram. It would be shown in the diagram below

Looking at the diagram,

Area of family room = 5.5 * 24 = 132 square feet

Area of hallway = 15.5 * 4 = 62 square feet

Total area to be covered with carpet is

132 + 62 = 194 square feet

Since the cost per square foot is $4, then the cost of putting carpet in the family room and hallway is

194 * 4 = $776* 4 = $776

riadik2000 [5.3K]

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

1. Multiply the entire first equation by -3.

-3(3c+5t=52)

2. Simplify the equation from above:

-9c-15t=-156

3. Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

4. You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

5. Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

6. Simplify the equation above:

3c+43.75=52

7. Subtract 43.75 from both sides of the equation:

3c=8.25

8. Divide both sides by 3 to get your c value:

c=2.75

The large rectangle below represents one whole. What percent is represented by the shaded area? (URGENT)
nikitadnepr [17]

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}

Convert into a decimal:

\frac{2}{5}= 0.4

Multiply the decimal by 100 to get the percent:

0.4*100=40

So, forty percent of the rectangle is shaded.

Hope this helps.
