Enter your answer in the box. The actual width of the kitchen is feet.
For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.
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.
The balcony of an apartment is 4 feet wide by 7 feet long. On a scale drawing of the apartment, the balcony is 0. 8 inches wide by 1. 4 inches long.
The actual length of the balcony is 7 feet or 84 in (1 ft = 12in), and on scale the length of the balcony is 1.4 in. Thus, the scale factor is,
[tex]r=\dfrac{1.4}{84}\\r=\dfrac{1}{60}[/tex]
Thus, the scale factor is 1/60.
The length of the kitchen is 2.8 in on map. Let L is the actual length of the kitchen. Therefore,
[tex]r=\dfrac{2.8}{L}\\\dfrac{1}{60}=\dfrac{2.8}{L}\\L=168\rm in\\L=14\rm ft[/tex]
The width of the kitchen is 2.4 in on map. Let W is the actual width of the kitchen. Therefore,
[tex]r=\dfrac{2.4}{W}\\\dfrac{1}{60}=\dfrac{2.4}{W}\\W=144\rm in\\W=12\rm ft[/tex]
Thus, For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.

Solve for y 8x-7y=23 (fill all of the boxes)
Answer:
i think this is the correct answer
Step-by-step explanation:
Simplifying
8x + -7y = 23
Solving
8x + -7y = 23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
8x + -7y + 7y = 23 + 7y
Combine like terms: -7y + 7y = 0
8x + 0 = 23 + 7y
8x = 23 + 7y
Divide each side by '8'.
x = 2.875 + 0.875y
Simplifying
x = 2.875 + 0.875y
Fill in the table using this function rule.

Answer:
D.) Max started at a height of 30 meters and is ascending at 10 meters per hour.
Step-by-step explanation:
This equation y = 10x + 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking
Max started at the height of 30 meters and is ascending at a rate of 10 meters per hour. Then the correct option is A.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The equation is y = 10x + 30.
Where y is Max's elevation in meters and x is the number of hours.
Max has been hiking.
From the equation, we can conclude.

Answer:
5 cups of flour needed to make 60 cookies.
Step-by-step explanation:
24 cookies → 2 cups of flour
1 cookies → (2/24) cups of flour
60 cookies → [(2/24)*60 ] cups of flour
60 cookies → 5 cups of flour needed
Answer:
5 cups
Step-by-step explanation:
If 2 cups makes 24 cookies, then 1 cup makes 12 cookies. Since 12 times five is 60, 1 cup of flour filled five times makes 60 cookies so you will need 5 cups of flour.
