If you have a calculator or better if its a graphing calculator itll be easy, but if u dont then you just divide them by each other and you get a decial

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 13.33% of 37 1/2 ft; 37 1/2 ft is 750% 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 13.33% of 37 1/2 ft; 37 1/2 ft is 750% 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:

Given:

Length = l
Width = w
Perimeter = P = 44 in

<h3>Solution</h3>

Equations as per given:

l - w = 6
P= 2(l+w) = 44 ⇒ l +w = 22

Adding up the two equations:

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

Then finding the value of w:

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

Answer: 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.
