Step-by-step explanation:

The height of the ramp is 49.45in

Data;

To solve this problem, we can use trigonometric ratio SOHCAHTOA

Since we have the value of the angle and length of the ramp, this can be illustrated as hypotenuse and angle between the hypotenuse and opposite of the right-angle triangle.

From the information above, we have angle and hypothenuse but we need to solve for the opposite of the right-angle triangle. The sine angle can solve this problem.

[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin 22 = \frac{x}{132} \\x = 132 sin 22\\x = 49.45 in[/tex]

The height of the ramp is 49.45in

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

no it can not be simplified and

Here, We have,

From above, We can conclude that,

a = bk, b = ck, c = dk

a = dk³ , b = dk² , c = dk

By solving RHS :-

[tex]\sf{√(a - b - c)(b-c-d) }[/tex]

[tex]\sf{√(dk³ - dk² - dk) (dk² - dk - d) }[/tex]

We have to prove that √(a - b - c)(b-c-d) = √ab-√bc-√cd

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.

The area of shaded region = area of triangle - area of circle = 33.73 sq. m.

Answer:

  9x + 30 ≤ 22

Step-by-step explanation:

Let x be "a number."

"the sum of a number times 9" is 9x +

"and 30"                                          9x + 30

"is at most 22"                                 9x + 30 ≤ 22

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.
