To find the width, divide the area by the length.

Width = 375 / 25

Width = 15 feet.

Answer:

Width of rectangle is 15 ft !

Step-by-step explanation:

Given :-

• <em>Area</em><em> </em><em>of</em><em> </em><em>recta</em><em>ngle</em><em> </em><em>=</em><em> </em><em>3</em><em>7</em><em>5</em><em> </em><em>ft²</em><em> </em>

<em>•</em><em> </em><em> </em><em>Length</em><em> </em><em>of</em><em> </em><em>recta</em><em>ngle</em><em> </em><em>=</em><em> </em><em>2</em><em>5</em><em> </em><em>ft</em><em> </em>

<em>•</em><em> </em><em>Let</em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>recta</em><em>ngle</em><em> </em><em>be</em><em> </em><em>b</em><em> </em><em>ft</em><em> </em>

<em>Formu</em><em>la</em><em> </em><em>for</em><em> </em><em>area</em><em> </em><em>of</em><em> </em><em>recta</em><em>ngle</em><em> </em>

<em>=</em><em> </em><em>(</em><em> </em><em>lenght</em><em> </em><em>)</em><em> </em><em>(</em><em> </em><em>width</em><em> </em><em>)</em>

<em>Substituting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>,</em>

<em>3</em><em>7</em><em>5</em><em> </em><em>ft²</em><em> </em><em>=</em><em> </em><em>2</em><em>5</em><em>f</em><em>t</em><em> </em><em>(</em><em> </em><em>b</em><em> </em><em>ft</em><em> </em><em>)</em>

<em>\frac{375 {ft}^{2} }{25ft}  = bft</em>

<em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>b</em><em> </em>

<em>So</em><em>,</em><em> </em><em>the</em><em> </em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>recta</em><em>ngle</em><em> </em><em>is</em><em> </em><em>1</em><em>5</em><em> </em><em>ft</em><em> </em>

Trava [24]

Answer:

Eli has to run for 2.25 minutes at this pace to win the bet.

Step-by-step explanation:

At his last track meet, Eli ran the 400-meter dash in 54 seconds.

So, the speed of Eli's run is \frac{400}{54} \times 60 = 444.44 meters per minute.

Now, if Eli is determined to run a whole kilometer with the same speed, then it will take Eli to run 1 kilometer within \frac{1000}{444.44} = 2.25 minutes.

Hence, Eli has to run for 2.25 minutes at this pace to win the bet. (Answer)

Which expression simplifies to 41? Choose all that apply!
Arada [10]

Answer:

None of the expressions is simplified to 41.

Step-by-step explanation:

You have to follow the P.E.M.D.A.S., this is:

P:Parentheses first.

E:Exponent next.

M:Multiplication.

D:Division.

(Multiplication and Division is whichever come first, from left to right)

A: Addition.

S: Subtraction.

(Addition and Subtraction is whichever come first, from left to right).

<u><em>We are going to analyze every option:</em></u>

1. 10+ 2.4 - 1

First we have to solve the multiplication:

10+ 2.4 - 1=10+8-1

Now we have to solve the addition and subtraction from left to right:

10+8-1=18-1=17\neq 41

This is not a correct answer.

2. 10+2.(4-1)

We have to solve the parentheses first:

10+2.(4-1)=10+2.(3)

Now the multiplication and then the addition.

10+2.(3)=10+6=16\neq 41

This is not a correct answer.

3. (10+23).4-1

We have to solve the parentheses first:

(10+23).4-1=(33).4-1

Now the multiplication and then the subtraction:

(33).4-1=132-1=131\neq 41

This is not a correct option.

4. 10+(2^2.4)-1

We have to solve the parentheses first, in the parenthesis first we have to solve: 2^2 and then do the multiplication.

10+(2^2.4)-1=10+(4.4)-1=10+16-1

Now we have to solve the addition and subtraction from left to right:

10+16-1=26-1=25\neq 41

This expression is not a correct option.

Then none of the expressions is simplified to 41.
