Scale factor is the ratio of representation measurement of the figure to the original figures.
The actual dimensions of the kitchen is 12 ft by 14 ft.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
Given information-
Dimensions of the balcony of the apartment is 4 ft by 7 ft or 48 in by 84 in (multiplying it by 12 to convert in inches).
Dimensions of the balcony of the apartment is 0.8 ft by 1.4 in on the scale of drawing.
Dimensions of the kitchen is 2.4 inches by 2.8 inches on the scale of drawing.
The scale factor of the width of the balcony is the ratio of scale dimension of width and the actual dimension of the width . Thus,
[tex]r=\dfrac{0.8}{48} \\r=\dfrac{1}{60}[/tex]
The scale factor of the length of the balcony is the ratio of scale dimension of length and the actual dimension of the length . Thus,
[tex]r=\dfrac{1.4}{84} \\r=\dfrac{1}{60}[/tex]
Thus the scale factor of the length and width of the scale is same which is 1/60.
As the scale is same for the balcony and the kitchen. Thus the scale factor would also be same.
The scale factor of the width of the kitchen is the ratio of scale dimension of width and the actual dimension of the width .
Let the width of the kitchen is x in.Thus
[tex]\dfrac{1}{60}=\dfrac{2.4}{x} \\x=144\rm in[/tex]
Thus the width of the kitchen is 144 in or 12 ft.
The scale factor of the length of the kitchen is the ratio of scale dimension of length and the actual dimension of the length .
Let the length of the kitchen is y in. Thus
[tex]\dfrac{1}{60}=\dfrac{2.8}{y} \\y=168\rm in[/tex]
Thus the length of the kitchen is 168 in or 14 ft.
Hence, the actual dimensions of the kitchen is 12 ft by 14 ft.

REMODELING The Clearys are replacing the flooring in their 15 foot by 18 foot kitchen. The new flooring costs $17.99 per square yard. The formula f(x) = 9x converts square yards to square feet. a. Find the inverse f–1(x). What is the significance of f–1(x) for the Clearys? b. What will the new flooring cost the Clearys?
Answers
The inverse of the function for square feet, gives the area in square yard
from which the cost of the flooring is calculated as $539.7.
Response:
a. The inverse [tex]\underline{f^{-1}(x) = \dfrac{x}{9}}[/tex] can be used by the Clearys to calculate the cost if the flooring.
b. $539.7
What is the inverse of a function and how can it be used?Given:
The dimensions of the flooring = 15 foot by 18 foot
Cost of the new flooring = $17.99/yd.²
The formula that converts square yards to square feet is f(x) ≈ 9·x
a. The inverse function gives the x-values as an output from an input of
the y-value.
The inverse of the function, f⁻¹(x), is the function that converts square
feet to square yards, which is given as follows;
[tex]\underline{f^{-1}(x) = \dfrac{x}{9}}[/tex]The significance of f⁻¹(x) for the Clearys is that it gives the number of
square yards required for the flooring from the square feet, from which
the cost of the flooring can be calculated.
b. The cost of the new flooring is therefore;
[tex]Cost = \$17.99/yd.^2 \times f^{-1}(x) = \$17.99/yd.^2 \times \dfrac{15 \, ft. \times 18 \, ft. }{9} = \mathbf{\$539.7}[/tex]
The new flooring will cost $539.7Learn more about inverse functions here:

A museum exhibit hall is the shape of a regular octagon. The distance between any two parallel walls is 30 feet. What is the perimeter of the exhibit hall, rounded to the nearest foot?
Answers
The perimeter of the hall is the sum of its side lengths.
The perimeter of the museum exhibit hall is 240 feet
How to determine the perimeterFrom the question, we understand that the shape of the museum exhibit hall is a regular octagon
The perimeter of a regular octagon is:
p = 8l
Where l represents the side length of the octagon
So, we have:
p = 8 * 30 feet
Evaluate the product
p = 240 feet
Hence, the perimeter of the exhibit hall is 240 feet

Answers
Answer:
p = 11.75 - 2 = 9.75
Explanation:

Amelia paid $225 to have her television fixed. The repair
shop charged $35 per hour for repairs and $85 for parts.
Write an equation that can be used to find how many
hours, h, it took to repair Amelia's television.
Answers
Answer:
35h + 85 = 225
Step-by-step explanation:
Since the shop charges $35 per hour, multiply h by 35 like this: 35h
$85 is already added on top of that, so add 85 to it like this: 35h + 85
All of this has to equal 225 since Amelia paid $225
35h + 85 = 225
