Lynna [10]

Answer:

$\frac{13}{38}$ or $13:38$ .

Step-by-step explanation:

We have been given that there are 38 cars parked in the parking structure. There are 13 parking spaces that are empty. We are asked to find the ratio of available parking spaces to parked cars.

To find the ratio of available parking spaces to parked cars, we will set an equation as:

$\frac{\text{Available Parking space}}{\text{Parked cars}}=\frac{13}{38}$

Therefore, the ratio of available parking spaces to parked cars is $\frac{13}{38}$ or $13:38$ .

A certain three-digit number equals fifteen times the sum of its digits. if its digits are reversed, the resulting number exceed

lara31 [8.8K]

If the digits are a, b and c, the number n is 100a+10b+c

Here are the equations:

a number equals fifteen times the sum of its digits:

100a+10b+c = 15(a+b+c)

if its digits are reversed, the resulting number exceeds n by 396:

100a+10b+c+396 = 100c+10b+a

the one’s digit is one larger than the sum of the other two:

a+b+1 = c

Solving it gives you a=1, b=3, c=5, the number is 135.

Natalija [7]

Answer:

2 miles per hour

Step-by-step explanation:

1/4 x 4 = 1

1/2 x 4 = 2

1/4 is a quarter of 100, so you have to multiply it by 4 to get 100% or 1.

So 1/2 x 4 is 2, which is the mph.
