Rachel has 75 books.18 of the books are comics books. The rest of books are novels. a. What percentage of the books are novels?
b. What percentage of her books are comics?

Novels: 24% Comics: 76%

Step-by-step explanation:

Divide 18/75= 0.24= 24% to find percent of novels

Subtract 100-24= 76 to get the remaining percent

Or

Subtract 75-18= 57 (to get the number of comics she has)

Divide 57/75= 0.76= 76% to find percent of comics

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
