An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 hours. If the pool is 1/3 filled and than the inlet pipe and drain pipe are opened how long would it take to fill the pool

Answers

Answer 1

Answer:

Answer:

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs

Solution:

Let x = time it will take to fill the pool

$(1)/(33)$ = work rate of inlet pipe

$(1)/(34)$ = work rate of drain pipe

Using the formulae

Volume of flow=work rate $*$ time

Let us assume complete time of pool to fill = 1

Remaining fraction of pool to be filled = $1-(1)/(3)=(2)/(3)$

$\begin{array}{l}{(1)/(33) x-(1)/(34) x=(2)/(3)} \n\n {(x)/(33)-(x)/(34)=(2)/(3)}\end{array}$

$(34 x-33 x)/(33 * 34)=(2)/(3)$

$34 x-33 x=(2 * 34 * 33)/(3)$

$\begin{array}{l}{x=(2244)/(3)} \n\n {x=(3168)/(3)} \n\n {x=748}\end{array}$

Time it will take to fill the pool = 748 hrs

Happy to Help!

Total cose
3(38)
=114
tax is 8% so 114+114(0.08)
=114+9.12

Edward had 45 water bottles. If he drank 1/9 of water bottles, how many did he drank?

Answers

Answer:

He drank 5 water bottles.

Step-by-step explanation:

We need to find one-ninth (1/9) of the total number of water bottles (45).

Multiply the two numbers together:

$(1)/(9)*45$

$=(45*1)/(9)$ Combine into numerator (top) to multiply

$=(45)/(9)$ Simplify the fraction by dividing top by bottom

$=5$ Answer

Therefore, Edward drank 5 water bottles.
