  6 buckets

Step-by-step explanation:

Look at the ratio:

  1/3 cup kernels : 2 quarts popcorn

  2/3 cup kernels : 4 quarts popcorn : 1 bucket . . . . multiply by 2

  2 cups kernels : 3 buckets . . . . . . . . . . . . . . . . . . . . .multiply by 3

  4 cups kernels : 6 buckets popcorn . . . . . . . . . . . . multiply by 2

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.
