5 ft is ____ % of 37 1 2 ft; 37 1 2 ft is ____ % of 5 ft
hichkok12 [17]

Answer:

The answer is:

5 ft is <u>13.33</u>% of 37 1/2 ft; 37 1/2 ft is <u>750</u>% of 5 ft.

Step-by-step explanation:

Given:

5 ft is ____ % of 37 1 2 ft.

Now, to find the __ :

Let __ be x.

So, 5 ft is x\% of 37 1/2

5=x\% of 37\frac{1}{2}

⇒ 5=\frac{x}{100} \times \frac{75}{2}

⇒ 5=\frac{75x}{200}

Multiplying both sides by 200 we get:

⇒ 1000=75x

Dividing both sides by 75 we get:

⇒ 13.33=x

⇒ x=13.33\%.

Now, 37 1/2 ft is x% of 5 ft.

\frac{75}{2} =x\%\ of\ 5

\frac{75}{2}=\frac{x}{100}\times 5

\frac{75}{2} =\frac{5x}{100}

Multiplying both sides by 100 we get:

\frac{7500}{2} =5x

Dividing both sides by 5 we get:

750=x

x=750\%

Therefore, the answer is 5 ft is <u>13.33</u>% of 37 1/2 ft; 37 1/2 ft is <u>750</u>% of 5 ft.

A rectangle is 6 inches longer than it is wide. The perimeter of the rectangle is 44 inches.Write and solve an equation for the
Nataly_w [17]

Answer:

Length is 14 in

Width is 8 in

Step-by-step explanation:

<u>Given:</u>

  • Length = l
  • Width = w
  • Perimeter = P = 44 in
<h3>Solution</h3>

<u>Equations as per given:</u>

  • l - w = 6
  • P= 2(l+w) = 44 ⇒ l +w = 22

<u>Adding up the two equations:</u>

  • l - w  + l +w = 6 + 22
  • 2l = 28
  • l = 28/2
  • l = 14 in

<u>Then finding the value of w:</u>

  • w = l -6
  • w = 14 - 6
  • w = 8 in

<u>Answer:</u> The length of the rectangle is 14 inches and width is 8 inches

At 8am,Ming Wei started travelling from Town A to Town B.At 8:40am, Ali started travelling from Town B to Town A.Mingwei's speed
Vesnalui [34]
Let's write some equations.

Mingwei's distance from Town A after x hours from 8:00 is 45x.

Ali's distance from Town B after x hours is 30x-20, since he doesn't start walking for 40 minutes.

When Mingwei's distance is twice Ali's, they've met up (since their distance from Town A is twice their distance from Town B).

So, this gives 45x=60x-40, so 15x=40, so x=\frac{40}{15} = \frac{8}{3}, so the time is 10:40.

After \frac83 hours, Mingwei has traveled 45 * 8 / 3 = 120 kilometers while Ali has traveled sixty, so the distance between the towns is 180 kilometers.
