Leyla is redecorating her living room. The room is in the shape of a right rectangular prism. The dimensions of the room are 15 feet in length by 10 feet in width by 8 feet in height.
She plans to cover the floor with hardwood. The cost of the hardwood is $3 per square foot. She plans to cover the walls and the ceiling with paint. Each container of paint costs $30 and can cover 275 ft².
What is the total cost of the hardwood flooring and paint needed for this room?
Drag and drop the responses to correctly complete these sentences.
Answers
Answer:
Total floor: 150 sq ft = $450
Wall and Ceiling: 550 sq ft = $60
Total cost $510
Step-by-step explanation:
Floor: 15 sq ft * 10 sq ft (L * W) = 150 sq ft
150 sq ft * $3 = $450
Walls: 2(H * L) = 2(8*15) = 240 sq ft
2(H * W) = 2(8*10) = 160
Total walls sq ft = 400 sq ft
Ceiling is same as floor = 150 sq ft
Total sq ft painted = 550 sq ft
550 sq ft / 275 sq ft (covered per paint) = 2 paints = $60
$450 floor + $60 paint = $ 510
Answer:
$510
Step-by-step explanation:
The floor of the room measures 15 ft in length and 10 ft in width.
The area of the floor is length × width = 15 ft × 10 ft = 150 ft².
The hardwood costs $3/ft².
The cost of the hardwood is: $3/ft² × 150 ft² = $450
The area of the walls is the lateral surface area of the rectangular prism.
The lateral surface area of the rectangular prism is the perimeter of the base times the height.
perimeter of the base = 15 ft + 15 ft + 10 ft + 10 ft = 50 ft
height = 8 ft
lateral area = total area of the walls = perimeter × height = 50 ft × 8 ft = 400 ft²
The paint costs $30/(275 ft²).
She needs to paint 400 ft².
400 ft² / 275 ft² = 1.45
She needs 1.45 containers of paint, but she must buy full containers of paint, so she must buy 2 containers since 1 container is not enough.
Cost of paint: 2 × $30 = 60
Total cost of hardwood and paint = $450 + $60 = $510

You look up some information.
• One gallon of water covers about 13.8 square feet.
• Near the mall, an average city block is about 300 feet by 300 feet.

Since the area 400 gallons will cover, 5520 square feet is less than the area of half a city block which is 45000 square feet, the Newscasters claim is wrong.
What is the area of the city block?The area of the city block is calculated from the product of the dimensions provided:
The city block is in form of a square, hence it's area = side × side
Dimension of city block = 300 feet by 300 feet.
Area of city block = 90000 square feet
Half of area of city block = 45000 square feet
1 gallon covers 13.8 square feet
400 gallons will cover = 400 × 13.8 = 5520 square feet
The area 400 gallons of coffee will cover is less than 45000 square feet.
Therefore, the news caster's claim is wrong.

How much would you have after 4 years if you invested $1250 with a quarterly compounding interest rate of 5%?
Answers
Using compound interest, it is found that you would have $1524.86.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem, we have that the values of the parameters are given by: P = 1250, r = 0.05, n = 4, t = 4. Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A(4) = 1250\left(1 + \frac{0.05}{4}\right)^{4 \times 4} = 1524.86[/tex]

Jasmine is trying to replace the flooring in her rectangular bedroom. When she measured the width and length of the floor, she found that the length is 5 ft. longer than the width. If the perimeter of the room is 50 ft., how much flooring will she need to replace the existing flooring in her room?
Answers
By finding the area of the rectangle, we will see that she will need 150 ft^2 of flooring.
How to get the area of the rectangle?
For a rectangle of length L and width W, the area is:
A = L*W
And the perimeter is:
P = 2*(L + W).
In this case, we know that the length is 5ft longer than the width, so we can write:
L = W + 5ft
We also know that the perimeter is 50ft, so we can write:
P = 50ft = 2*(W + 5ft + W)
50ft = 4*W + 10ft
40ft/4 = W = 10ft
So the width is 10 ft, and then the length will be:
L = 10ft + 5ft = 15ft
So the area of the rectangle is:
A = 10ft*15ft = 150 ft^2
She will need 150 ft^2 of flooring.

Step-by-step explanation:
The first option is not because the numerator and denominator are flipped.
The second option is not because this one is positive while the one given is negative.
The third option is equivalent.
The fourth option is equivalent.
The fifth option is equivalent because - 48 / 17 = -2 [tex]\frac{14}{17}[/tex] when turned into a mixed number.
Answer:
[tex]\frac{48}{-17}, \frac{-48}{17}, -2\frac{14}{17}[/tex] (the last 3 options)
Step-by-step explanation:
As long as the negative is in either the numerator or the denominator (if it is in both then it is positive because the negatives cancel out), the entire fraction will be negative, so both [tex]\frac{48}{-17}[/tex] and [tex]\frac{-48}{17}[/tex] work as answers. The last option is just a simplified version of the fraction.
