Answer: 200 gallons
Step-by-step explanation: Change the percentage 20% into a decimal so .20. Then since you are taking away from the 40 gallons divide 40 by .20 to get 200 gallons
Answer:1/4
Step-by-step explanation: divide both numbers by 4
If you take a look at my really poorly drawn diagram, we can see it is a trigonometry problem. The angle, however, is outside the triangle, and we can find the angle inside the triangle next to it by taking it away from 90°:
90°0' - 72°54' = 17°6' ≈ 17.1°.
We can find the other angles becuase one is 90° and the other is:
180°-90°-17°6'=72°54' ≈ 72.9°(which you can see if you know your angle theorems).
We now have diagram 2, nicely simplified so we can see where to go.
Using the Sine Rule, i.e.

We can rearrange to find our length b:

Substituting numbers in:

b=366 feet.
Answer:
Average: 26.223529411764706 (Please round to the place value necessary since it does not say in the question.)
Step-by-step explanation:
We first find the number of items sold: 170
Then we find the total cost: 4458
We then divide 4458 by 170
We end up with the answer 26.223529411764706. (Please round to the place value necessary since it does not say in the question.)
