The <em><u>correct answer</u></em> is:
D) The amount a person pays for gas compared with the number of gallons purchased
Explanation:
A constant rate of change means that for every x, y increases the same amount.
In the situation "The amount a person pays for gas compared with the number of gallons purchased
," the independent quantity, or x-value, is the number of gallons, and the dependent quantity, or y-value, is the amount paid. Since gas has a set price per gallon, for every gallon purchased, the total amount paid goes up the same amount. This means it has a constant rate of change.
To answer set up a proportion.
You are trying to find how many books are in the entire book given 80% of the pages which is 180. Thus you put 80 over 100 and 180 over X(total number of pages). Then you cross multiply to solve for x.
it's a right triangle so you use Pythagoras' theorem.
√28²-14²=
√784 - 196 =
√588
24.24 units (rounded 24.25)
your answer is 24.25 units
5n+11=46
5n=35 (subtract 11 from both sides)
n=7 (divide both sides by 5)
