21 - 16.75 is 4.25. Do the problem on a calculator and you'll get it.
Fraction of tank drops in every 10 minutes = 1/3 inches.
We need to find the expected change in the tank's water level after 2.25 hours.
Let us convert 2.25 hours in minutes.
1 hours = 60 minutes.
2.25 hours = 2.25 × 60 = 135 minutes.
<em>We need to divide 135 by 10.</em>
We get 13.5.
Now, we need to <em>multiply 1/3 by 13.5</em>, we get.
13.5/3 = 4.5 inches.
<h3>So, tank would drop 4.5 inches after 2.25 hours.</h3>
Yes because if you plug in (-1,2) to each equation you get a true statement.
Answer:
2 2/5
