Answer:

3*c - 8

Step-by-step explanation:

She baked 3 batches with c cookies each, that's c + c + c cookies (the "c" represents a number, we don't know the exact amount, is the variable of our equation). But then she ate 8, so we need to subtract that amount from the one we had before, that's c +c + c - 8.

We can rewrite that as 3*c - 8

Two different sizes of square metal duct are joined by a piece that is a frustum of a pyramid. Find the lateral surface area, if
Allisa [31]

Answer:

288 in²

Step-by-step explanation:

The formula used to solve this question is :

Lateral Surface Area = s( P1 + P2)

Where s = slant height = 2 inches

P1 and P2 = Perimeter of the bases

Perimeter of base 1 = 4 × length of the end of the small square

4 × 17 inches = 68 inches

Perimeter of base 2 = 4 × length of the end of the large square

4 × 19 inches = 76 inches

Lateral Surface Area = 2 × (68 + 76)

= 2 × 144

= 288 in²

Angelina_Jolie [31]

Using proportions, it is found that $55.7 billion was donated to educational organizations.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:

A = 0.15 x 371 = $55.7 billion.

Hence $55.7 billion was donated to educational organizations.
