Frodo ran 2 3/5 miles in 7/12 of an hour. How many miles can Frodo run in one full hour?

Answers

To find how many miles he ran, we need to convert 7/12 of an hour to a full hour. To get a full hour, we must multiply 7/12 by 12/7. Knowing this, we need to multiply 2 3/5 miles by 12/7.

2 3/5 * 12/7

This would be

156/35 miles or 4 16/35 miles

b. Bailey and Carlos
c. Carlos and Abigail
d. They are all equivalent.​

Answers

Answer:

The first expression and the third expression

Step-by-step explanation:

This is because if you simplify the first expression, you have to multiply

-(4h-3s+1)

And you have to make the  +/- symbols opposite from the negative symbol on the left  when you multiply

so you get..

-4h+3s-1, which is also the third one

So the first one and the third one are the same expressions

The correct answer is C
Carols and Abigail

Find the measure of angle AOB

Answers

Answer:

101°

Step-by-step explanation:

20 + 25 = 45

3+2 = 5

5x + 45 = 180

Subtract 45 from 45 and 180 (both sides)

5x = 135

Divide 5x and 135 (both sides) by 5, to finally get..

x=27

3 x 27 + 20 = 101

2 x 27 + 25 = 79

Angle B.O.C = 79

Angle A.O.B = 101
