2 answers:

7 0

Simplify by dividing a common factor (5). 15/24. Check to see if it can be simplified. Repeat (using 3). 5/8. Check to see if it can be simplified. It can't, so the answer is 5/8

If you Divide 5 by 75/120 it equals 15/24 then divide 3 by 15/24 and you get 5/8 which is the answer because you can't simplify no more. (Sorry I was thinking as I was explaining)

Rebecca went swimming yesterday. After a while she had covered one fifth of her intended distance. After swimming six more lengt

alukav5142 [94]

Answer:

Option E.

Step-by-step explanation:

Let the intended length of Rebecca's swimming is = x units

and we assume the length of the pool = l units

Now it is given in the question that " She covers one fifth of her intended distance "

That means distance covered = $\frac{x}{5}$

" After swimming six more lengths of the pool she had covered one quarter of her intended distance"

So $\frac{x}{5}+6(l)=\frac{x}{4}$

$6l=\frac{x}{4}-\frac{x}{5}$

$6l=\frac{x}{20}$

x = 20×(6l)

x = 120l

Therefore, Rebecca has to complete 120 lengths of the pool.

Option E is the answer.

Express each rate as a unit rate. (5points each)

neonofarm [45]

To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.

For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.

Likewise for the other question it would be 270/15.

paul is diving and is 3.5 feet below sea level. he is descending at a rate of 0.5 feet per minute. if paul is now at 12 feet how

andrezito [222]

Answer:

He has been diving for 17 minutes

Step-by-step explanation:

* Lets explain how to solve the problem

- Paul is diving and is 3.5 feet below sea level

- He is descending at a rate of 0.5 feet per minute

- Paul is now at 12 feet

∵ His initial position is at 3.5 feet below the sea

∵ He is descending, that means he is moving down

∵ His final position is at 12

∴ He is descending a distance = 12 - 3.5 = 8.5 feet

∵ He is descending at a rate of 0.5 feet per minute

∵ He is descending 8.5 feet

∵ Time = distance ÷ rate

∴ His time of descending = 8.5 ÷ 0.5 = 17 minutes

* He has been diving for 17 minutes
