$180 Is 100%

$180 Divided By 100 = 1.8

$1.8 Is 1%

$1.8 x 5 = 9

Sales Tax Was $9

$1.8 x 1.5 = 2.7

Handling Fee Was $2.7

$180 + $9 + $2.7 = 191.7

She Paid $191.7

Solve the equation by completing the square. -9n^2+79+=-18n
poizon [28]
Hello,
-9n²+79=-18n
==>9n²-18n-79=0
==>9(n²-2n+1-1)-79=0
==>9(n-1)²-88=0
==>[3(n-1)-2√22][3(n-1)+2√22]=0
==>3(n-1)=2√22 or 3(n-1)=-2√22
==>n-1=2/3*√22 or n-1=-2/3*√22
==>n=1+2/3*√22 or n=1-2/3*√22

You are remodeling your bedroom. You will paint all 4 walls and the door. There are no windows in the room. The floor is 9' by 1
Aleksandr [31]

Answer:

Part 1) The area of the 4 walls is 368\ ft^2

Part 2) You will have to buy 2 gallons

Part 3) You will have to buy 3 gallons

Part 4) \$75

Part 5) The area of the floor is 126\ ft^2

Part 6) \$850.5

Part 7) \$1,008

Part 8) \$472.5

Step-by-step explanation:

Part 1) What is the area of all 4 walls together?

we know that

The area of all 4 walls together is equal to the perimeter of the floor multiplied by the height of the wall (8 ft)

so

The perimeter of the floor is

P=2(9+14)=46\ ft

The area of the walls is

46(8)=368\ ft^2

Part 2) If a gallon of paint covers 350 sq. ft., How many gallons will you have to buy?

using proportion

\frac{1}{350}\ \frac{gal}{ft^2}=\frac{x}{368}\ \frac{gal}{ft^2}\\\\x=368/350\\\\x=1.05\ gal

Remember that you can't buy a fraction of gallon

so

You will have to buy 2 gallons

Part 3) How many gallons will it take to put on 2 coats of paint?

Now the area will be

368(2)=736\ ft^2

using proportion

\frac{1}{350}\ \frac{gal}{ft^2}=\frac{x}{736}\ \frac{gal}{ft^2}\\\\x=736/350\\\\x=2.10\ gal

Remember that you can't buy a fraction of gallon

so

You will have to buy 3 gallons

Part 4) If the paint costs $25 per gallon, and you are applying 2 coats of paint, how much will you spend on paint?

To find the cost multiply the number of gallons by $25 per gallon

so

3(25)=\$75

Part 5) What is the area of the floor?

The area of the floor (rectangle ) is equal to multiply the length of the floor by the width of the floor

A=(9)(14)=126\ ft^2

Part 6) What is the cost to redo the floor in oak?

To find the cost multiply the area of the floor by $6.75 per square foot

so

126(6.75)=\$850.5

Part 7) What is the cost to redo the floor in maple?

To find the cost multiply the area of the floor by $8.00 per square foot

so

126(8.00)=\$1,008

Part 8) What is the cost to redo the floor in carpet?

To find the cost multiply the area of the floor by $3.75 per square foot

so

126(3.75)=\$472.5
