Answer:

Pretty Simple!

Now that you know about ratios and all that, this is pretty tame compared to the last problem.

Now, the problem is talking 2D(2 Dimensions)

The ratio is not going to work because it has only one parameter.

Thus, we need to square it!

(\frac{1}{20})^{2}  =\frac{1}{400}

Thus, we have your correct ratio.

Now, we only need to do the same thing for the triangle problem. Meaning that, we need to compare the ratios, with x as the thing we are looking for.

\frac{1}{400}=\frac{219}{x} \\x=87,600

See? X is practically handed to us.

Hope this helps!

A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/8 cup of brown sugar.
NeTakaya

Answer:

(a) 2 3/8 cups

(b) 3-cup

Step-by-step explanation:

1 1/2 + 3/4 + 1/8

The common denominator is 8

1 4/8 + 6/8 + 1/8 = 1 11/8 = 2 3/8 cups

I choose 3-cup mixing bowl since it fits 2 3/8 cups ingredients.

 . . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative

. . . so in short . . . the answer is . . . <span>NO</span>
