Answer:

son = 4

mom=36

m = 9s

m + 4 = 5(s+4)

m + 4 = 5s + 20

9s + 4 = 5s + 20

4s = 16

s = 4

m = 36

<h2>19.</h2><h3>Given</h3>
  • window width and height are in proportion to building width and height
  • window width and height are 11 in and 18 in, respectively
  • building height is 108 ft
<h3>Find</h3>
  • building width
<h3>Solution</h3>

The proportional relation can be written as

... (building width)/(building height) = (window width)/(window height)

Multiplying by (building height) gives

... (building width) = (building heigh) × (window width)/(window height)

... (building width) = 108 ft × (11 in)/(18 in)

... building width = 66 ft

<h2>21.</h2><h3>Given</h3>
  • map distance = 6.75 in
  • map scale = 1.5 in : 5 mi
<h3>Find</h3>
  • actual distance
<h3>Solution</h3>

The distances are in proportion, so

... (map distance) : (actual distance) = 1.5 in : 5 mi

Multiplying by (5 mi)/(1.5 in)×(actual distance), we have

... (5 mi)/(1.5 in)×(6.75 in) = (actual distance) = 22.5 mi

Can someone help and explain it to me pls?
Elza [17]

Answer:

Option C, 0 ≤ x ≤ 12

Step-by-step explanation:

the domain of a function is the set of inputs accepted by the function so all possible x values.

Since x-axis is time, time can never be negative

so the lowest x value is 0

the heights x values is the x intercept which is 12

hence option C

Question 32 of 40<br> The ratio<br> opposite<br> hypotenuse<br> describes which function?
Helen [10]

The ratio \frac{Opposite}{Hypotenuse } describes the Sine function . The correct option is C. Sine

<h3>Trigonometry </h3>

From the question, we are to determine the function that the ratio of <em>opposite </em>to <em>hypotenuse </em>describes

By SOH CAH TOA

We have that

Sine = \frac{Opposite}{Hypotenuse }

Cosine = \frac{Adjacent}{Hypotenuse }

and

Tangent = \frac{Opposite}{Adjacent}

Hence, the ratio \frac{Opposite}{Hypotenuse } describes the Sine function . The correct option is C. Sine

What is the value of x
Nesterboy [21]

Answer:

x = 2

Step-by-step explanation:

First simplify the equation.

  1. \frac{7}{9}x -\frac{4}{9} =\frac{1}{4} +\frac{5}{12}
  2. \frac{3}{9}x= \frac{3}{12} +\frac{5}{12}
  3. \frac{3}{9}x=\frac{8}{12}
  4. \frac{1}{3}x=\frac{2}{3}

Now multiply both sides by 3.

x = 2

I hope it helps you. Please choose my answer as the BRAINLIEST.
