ale4655 [162]

Answer:

3/2 miles per hour

Step-by-step explanation:

How do I find miles per hour from 2 fractions? For Example: If I ran for 1/2 miles when It lasted 1/3 of an hour. Would It be 1/6?

Given data

distance= 1/2 miles

time= 1/3 hour

Speed= distance/time

Substitute

Speed= 1/2/1/3

Speed= 1/2*3/1

Speed= 3/2 miles per hour

Help me plz. Haven’t been able to answer this problem. Even my TEACHER is stumped. (Mark brainliest)
vazorg [7]

Answer:

K 48 inches

Step-by-step explanation:

First lets determine how big of table cloth we need

The table is 3 ft in diameter which is 36 inches

That means the radius is d/2 = 36/2 = 18 inches

We need to add 5 inches to the radius to hang over the edge

18+5 = 23

We need to add the hem which is 1 inch

23+1 = 24

The radius is 24 inches

The diameter would be 2r = 2*24 = 48 inches
