For an apartment, the scale factor of the map is 1/60 and the kitchen's actual width of the is 12 ft wide.

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.

Answer:

The answer is 0.33 <3

Step-by-step explanation:

i put this here so its easier to see that answer then the steps :)! Try gauth math, its a great app! Just take a picture of a question and a expert will give you the right answer, and explanation.

Have a blessed week! :)

Step-by-step explanation:

Firstly take the unknown angle be x

now x + 138° = 180° {: linear pair}

x = 180-138

x = 42

now , angle 1+ angle x + 18 = 180 { because of angle sum property }

=> angle 1 +42 +18 = 180

=> angle 1 +60 = 180

=> angle 1 = 180-60

=> angle 1 = 120

ANSWER IS C The transformation below that caused AB to transform into A'B' is a reflection across the y-axis

How to translate a coordinate point to another

Given the following coordinates

A = (6, 2)

B = (2, 6)

A' = (-6, 2)

B' = (-2, 6)

According to the reflection rule, the reflection over y axis is given as:

Note that the x-coordinate was negated as seen from the translation A to A' and B to '.

Hence the transformation below that caused AB to transform into A'B' is a reflection across the y-axis

Answer:

0.05

Step-by-step explanation:

If dividing 9 by 0.45, basically .45/9, then you would get 0.05. :) You would need to use division, and move the places 2 over since there is a decimal.

The requried, 0.45 divided 9 gives the quotient of 0.05.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
To divide 0.45 by 9, we can write it as a fraction and simplify it:

0.45 ÷ 9 = 0.45/9

We can simplify the fraction by dividing both the numerator and denominator by 9:

0.45/9 = (0.45 ÷ 9)/(9 ÷ 9)
         = 0.05/1 = 0.05

Therefore, 0.45 divided by 9 is equal to 0.05.

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.

Step-by-step explanation:

First factor our the (4-x):  (8*4)(8*x)

Isolate the x:

32 -2 = 8x + 7x

Simplify both sides:

30 = 15x

Divide both sides by 15

Three friends decide to share the cost to rent an apartment equally. The apartments that they are considering cost at least 1 200 per month. Write and solve an inequality to represent each person's share of the rental cost​

Lets highlight some key words.

There are three friends and they equally have to share an unknown amount of number to earn up to the 1200 per month,

X=Amount needed to pay the rent fee.

Since there are 3 friends and they have to split we have to multiply,

3x, "At least" is less than or equal to so .

3x [tex]\leq[/tex]

Additionally theres 1200 per month so the friends need to share there rent and 1200 is the total it should be put as

3x [tex]\leq[/tex] $1200

To add up to the rent, and to solve the inequality

we have to do the opposite of multiplication, and divide.

1200/3 = 400, x [tex]\leq[/tex] 400

Step-by-step explanation:

Your calculator, spreadsheet, or any number of apps or web sites can compute a matrix product for you. The requirement for the product to exist is that the number of columns in the left matrix match the number of rows in the right matrix.

The product term at location (row, column) = (j, k) in the product is the dot-product of row j in the left matrix with column k in the right matrix. For example, in this matrix product, term (1,2) in the product is the dot-product ...
