It's probably the first one: "People responded to Earth Day with letters..."
Since it's more of a detail that supports a fact, it's not as important as the other three.

We have a shape that has an area of 112 inches squared. Convert the units to centimeters squared. (HINT: Perform multiple conver

Andre45 [30]

<h3>Answer: 722.5792 square centimeters</h3>

Work Shown:

$112 \text{ in}^2 = 112 \text{ in}^2 \times \frac{2.54 \text{ cm}}{1 \text{ in}} \times \frac{2.54 \text{ cm}}{1 \text{ in}}\\\\112 \text{ in}^2 = (112 \times 2.54 \times 2.54) \text{ cm}^2\\\\112 \text{ in}^2 = 112 \times (2.54)^2 \text{ cm}^2\\\\112 \text{ in}^2 = 722.5792 \text{ cm}^2\\\\$

Notes:

1 inch = 2.54 cm exactly
The conversion factor $\frac{2.54 \text{ cm}}{1 \text{ in}}$ is used to convert from inches to cm. The inches unit in the denominator cancels with one of the inches unit from the original 112 square inches figure.
We use two identical copies of the same conversion factor to convert from square inches to square centimeters. This is the "multple conversion" your teacher is referring to.
Think of "square inches", aka $\text{in}^2$ , as "inches times inches". Or think of a 1 inch by 1 inch square that has an area of 1 square inch. The same applies for the square centimeter unit as well.

Upperloaf Bakery is baking loaves of cornbread and poppy-seed blueberry cake. The recipe for one loaf of corn bread calls for 2

Answer:

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30

Step-by-step explanation:

Write a system of two inequalities to model loaves of bread and

cake that can be baked.

let

number of cornbread loaves = c

number of poppy-seed blueberry Cake loaves = p

corn bread

cups of flour = 2 1/4 = 2.25

teaspoon of baking soda = 1 1/4 = 1.25

One loaf of poppy-seed blueberry cake

cups of flour = 1 3/4 = 1.75

teaspoons of baking soda = 2 1/8 = 2.125

The bakery has 28 cups of flour and 30 teaspoons of baking soda in stock.

Quantity of flour to use

c(2.25) + p(1.75)

Quantity of baking soda to use

c(1.25) + p(2.125)

The inequality is

c(2.25) + p(1.75) ≤ 28

c(1.25) + p(2.125) ≤ 30

Alternatively,

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30
