Answer:
<em><u>option d is the right answer</u></em>
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>
Answer:
5.7 hours
Step-by-step explanation:
average speed = distance / time
rewriting gives
time = distance / average speed.
distance = 320 km
average speed = 56 km/hour
so
time = 320 / 56 = 5.7 hours
If you would like to solve the inequation G/4 - 8 <= - 10, you can calculate this using the following steps:
G/4 - 8 <= - 10
G/4 <= - 10 + 8
G/4 <= - 2 /*4
G <= - 2 * 4
G <= - 8
The correct result would be G <= - 8.
