A swimming pool can be filled in 18 hours if water enters through a pipe alone, or in 25 hours if water enters through a hose a

pychu [463]

I am not sure, but this is what I got:
<span>Pipe ALONE = 18 hours

Pipe ALONE in 1 hour = 1/18 of the pool

Hose ALONE in 1 hour = 1/25 of the pool

TOGETHER in 1 HOUR = 1/18 +1/25 = 43/450

TOGETHER they will fill the pool in 450/43 hours

So 5/6 of the pool will take 5/6 X 450/43 = 2250/ 258 = 8.7209302 hours OR

8 hours AND 43.26 minutes ANSWER

Hope this helps!

A mug is 1/8 full. The mug contains 1/6 of a cup of water. Find the capacity of the mug. Write the answer as a fration or mixed

Andre45 [30]

Answer:

The capacity of the mug = $1\frac{1}{3}$ cups

Step-by-step explanation:

Given - A mug is 1/8 full. The mug contains 1/6 of a cup of water.

To find - Find the capacity of the mug. Write the answer as a fraction or mixed number

Proof -

Let the capacity of water = x

Given that,

A mug is $\frac{1}{8}$ full of water

⇒Total cups of water in the mug = $\frac{1}{8} x$

Now,

Given that, The mug contains $\frac{1}{6}$ of a cup of water.

∴ we get

$\frac{1}{8} x$ = $\frac{1}{6}$

⇒x = $\frac{1}{6}$ × 8

= $\frac{8}{6}$

= $\frac{4}{3}$ = $1\frac{1}{3}$

⇒x = $1\frac{1}{3}$

∴ we get

The capacity of the mug = $1\frac{1}{3}$ cups

ikadub [295]

Answer:

George made the first mistake by multiplying by 7 instead of 8

Step-by-step explanation:

The total cars needed to have a mean of 24:

24 x 8 = 192

Total cars sold during the seven months:

18 + 22 + 26 + 12 + 25 + 20 + 19 = 142

Subtract the total cars sold from the total cars needed:

192 - 142 = 50

George needs to sell 50 cars in the eight month in order to have an average of 24 cars sold per month.
