<u>Answer:</u>
So all the possible solutions are:
<u />
<u>Solution Steps:</u>
<em>First you need to solve the real inequality to understand how to find the rest of the possible equations. </em>
<u>Add 78 to both sides:</u>
- <u />
Cancels Out
<em>So now we know the real answer, but it ask for all possible answers. </em>
(Means anything larger than 300 when you plug it into x - 78 > 300.)
<u>Numbers that are greater than 378:</u>
1.) (False)
2.) (True)
3.) (False)
4.) (False)
5.) (True)
6.) (True)
7.) (False)
8.) (True)
______________________________
The required time is mathematically given as
t-150 minutes.
This is further explained below.
<h3>What is the time?</h3>We know that the volume of the prism is given by.
Volume
Base Area
Base Area
Now,
Given that there is a twenty percent drop in the level of the pond during the first thirty minutes.
Because of this, the volume increases.
Now, the rate of emptying the tank is,
In conclusion, We also know that,
$$
Therefore, Colin must wait for the pond to drain for a total of 150 minutes.
