Answer:

74 minutes

Simple Solution:

If you use common sense you can just look at the ratios and find that 14 is 7 twice. You apply the same pattern to 37 and you get 74.

Explanation:

Convert the word problem into proportional relationships (Ratios). You should get (7/14) and (37/?). Divide 37 by 7 (Use a calculator for this). Multiply the quotient by 14 to get a final answer of 74.

Suzanne wants to put a fence around Her Square Garden. If the garden covers an area of 121m2, how many meters of fencing does sh
Delicious77 [7]
So, since it is square, we are going to take the square root of 121 which is 11. And since fencing goes around something, that means we have to find the perimeter. So since all four sides are the same length, we can just multiply 11 by 4 to get 44 meters of fencing

A recipe calls for 112 cups of mayonnaise and 38 cups of pecans. How much mayonnaise should be used if 1 cup of pecans is used?
Sauron [17]

Answer:

3 cups of mayonnaise will be required for 1 cup of pecan.

Step-by-step explanation:

A recipe calls for 112 cups of mayonnaise and 38 cups of pecans.

By using unitary method,

∵ 38 cups of pecans require mayonnaise = 112 cups

∴ 1 cup pecans requires mayonnaise = \frac{112}{38} cups

                                                             = 2.95 cups

                                                             ≈ 3 cups

Therefore, 3 cups of mayonnaise will be required for 1 cup of pecan.
