Answer:

$w =\frac{A}{l}$ .

Step-by-step explanation:

The formula for finding the area of a rectangle is A = l.w, where A is the area, l is the length and w is the width of the rectangle.

This formula is used to find area when l and w are known.

Now, if area A and length l are known the width w will be given by the formula $w =\frac{A}{l}$ .

Therefore, width = area by length. (Answer)

statuscvo [17]

Answer: 45

Step-by-step explanation:

In 2016, 1 out of every 5 people under the age of 50 used a cell phone to read e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read e-books.

Therefore, if there were x people under the age of 50 in 2016, then the number that used a cell phone to read e-books would be

1/5 × x = x/5

If there were approximately 225 million people under the age of 50 in 2016, then the number that were likely to have read an e-book on a cell phone is

225/5 = 45 people.

Please help me with these two questions

Hi! It will be a pleasure to help you finding the solution to this problem, so let's solve each part:

<h2>PART 1.</h2><h3>Finding the correct expression.</h3><h3>Correct answer:</h3>

$\boxed{A. \ 1.50h+4}$

From the problem, we know the following data of the problem:

Laval parked at the beach.
Laval paid a fixed price of $4 for a pass.
Laval paid $1.50 for each hour.

Our goal is to find the the expression for the total cost for parking at the beach for h hours. So:

Step 1: Since we have a fixed price, this value will appear in our expression:

$4$

Step 2: Since Laval paid $1.50 for each hour, this can be represented as the following expression:

$1.50h$

Finally, we can write total cost (C) as the sum of these two expressions:

$C=1.50h+4$

Finally, our correct option is A:

$\boxed{1.50h+4}$

<h2>PART 2.</h2><h3>Finding h.</h3><h3>Correct answer:</h3>

5 hours

Here we have to find how many hours Laval spent at the beach knowing that he paid a total amount of $11.50. From the previous part, we know that our expression is:

$C=1.50h+4 \\ \\ For \ C=11.50 \\ \\ 11.50=1.50h+4 \\ \\ Subtracting \ 4 \ from \ both \ sides: \\ \\ 11.50-4=1.50h+4-4 \\ \\ 7.5=1.50h \\ \\ Dividing \ both \ sides \ by \ 1.50 \\ \\ h=\frac{7.5}{1.50}=5$

Finally, he spent 5 hours at the beach
