- Reading a Cartesian Plane
Step-by-step explanation:
When we label a Cartesian Plane, we label counterclockwise starting at the top right corner:
Top Right Corner = 1st Quadrant
Top Left Corner = 2nd Quadrant
Bottom Left Corner = 3rd Quadrant
Bottom Right Corner = 4th Quadrant
We see that point B is in the Bottom Right Corner. Therefore, it is in the 4th Quadrant and our answer would be D.

For this problem, going to assume that the actual flow rate for both pipes is constant for the entire duration of either filling or emptying the pool. The pipe to fill the pool I'll consider to have a value of 1/12 while the drain that empties the pool will have a value of 1/20. With those values, the equation that expresses how many hour it will take to fill the pool while the drain is open becomes:
X(1/12 - 1/20) = 1
Now solve for X
X(5/60 - 3/60) = 1
X(2/60) = 1
X(1/30) = 1
X/30 = 1
X = 30
To check the answer, let's see how much water would have been added over 30 hours.
30/12 = 2.5
So 2 and a half pools worth of water would have been added. Now how much would be removed?
30/20 = 1.5
And 1 and half pools worth would have been removed. So the amount left in the pool is
2.5 - 1.5 = 1
And that's exactly the amount needed.</span>
