A. in a cookie mix, we find chocolate chip cookies, snickerdoodle cookies, and no-bake
cookies in a ratio of 4: 1: 4. if a bag of the mix contains 20 snickerdoodle cookies, how
many cookies in total are there?

Ratio: 4 chocolate chip : 1 snicker doodle : 4 no-bakes

1 * 20 = 20

4 * 20 = 80

80 chocolate chip : 20 snicker doodle : 80 no-bake

80 + 80 = 160

160 + 20 = 180

There are 180 total cookies.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
