Answer: 72 minutes
Step-by-step explanation:
Pipe A can empty the water in 180 minutes = (180/60) =3 hours
Pipe A does 1/ 3 of the job in 1 hour.
Pipe B can empty the water in 120 minutes = (120/60) = 2 hours.
Pipe B does 1/ 2 of thejob in 1 hour.
Together they will do:
1/ 3 + 1/ 2 = 5/6
Together, both pipes will do 5/ 6 of the job in one hour.
To get the total time to completely drain the water will be:
= 60 ÷ 5/6
= 60 × 6/5
= 12 × 6
= 72 minutes
It takes 72 minutes to empty the pool.

Answer:
let me bang you
Step-by-step explanation:
in and out in and out over and over i shot you with my lotion
I don't know. Let's figure it out and see.
18% of $13.90 means (0.18) x ($13.90) = $2.50
Add the tip to the bill: ($13.90) + ($2.50) = $16.40 .
Sadly, Dominic does not have enough money to leave an 18% tip.
He only has enough money to leave a 7.9% tip.
This doesn't hurt Dominic. He leaves the restaurant happy and well fed.
The only one who suffers for Dominc's inconsiderate failure to think ahead
is the waiter who served him his dinner.
See below for the explanation on how to determine the coordinates.
<h3>How to determine the coordinates?</h3>
The question is incomplete, and the missing parameters cannot be found.
So, I will give a general explanation on how to determine coordinates.
Assume that the start point of the buoy is
(x, y)
And the length of the buoy is k.
Depending on the position of the bouy on the coordinate plane, the endpoint can be any of the following coordinates (x - h, y), (x + h, y), (x, y + h) and (x, y - h)
