The cost of a gallon if gas recently doubled. by what percent did it increase?

If a price doubles, then it increases by 100%

Step-by-step explanation:

To find the percent increase, use the percent increase formula below.

(New - Old)/Old * 100 = percent increase

You can choose any number to be the old number and you'll get the same answer. For this purpose, we'll use 65. This would make the new value 130.

(130 - 65)/65 * 100 = Percent Increase

65/65 * 100 = Percent Increase

100% = Percent Increase

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
