A cookie recipe states for every 3 cups of flour, 1 1/2
teaspoons of vanilla are needed. How many
teaspoons are needed for 5 cups of flour?

This would mean 1/2 tsp is needed for each cup of flour, meaning the amount needed for 5 cups of flour is 2 1/2 tsp.

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
