<em>It will take 6 minutes to drain the pool.</em>
<h2>
Explanation:</h2>
As the problem states the height of the water in an above ground pool is 3ft. In other word:
- 3 ft is our starting point.
The pool needs to be drained at a Rate of Change of 1/2 inches per minutes. In other words:
- The rate of change is constant, so we'll have a line with slope -1/2.
Therefore, we can write an equation as:

To drain the pool implies that we don't have any water in the pool, in other words this is true if and only if:

So:

So, <em>it will take 6 minutes to drain the pool.</em>

Answer:
5
Step-by-step explanation:
Answer: just figure out 8 1/2 divide by six
Let L be the length of the deck
= 42 feet
Let W be the width of the deck =
28 feet
A = LxW
A = 42 feet x 28 feet
A = 1176 square feet
Remaining area to be painted =
1176 square feet – 350 square feet
<span>Remaining area to be painted = 826 square feet</span>
