A company that manufacturers deep freezers has developed a new formula of refrigerant, the substance used to cause cooling in re

frigerators and freezers. To determine if freezers using the new formula of refrigerant are more efficient than those using the company's original formula, they conducted an experiment with two identical freezers. The first freezer was cooled using the new formula, and the second freezer was cooled using the original formula. A gallon of water was placed in each freezer, and they measured the time required for the water to turn to ice. Match the terms with the correct descriptions in the context of this scenario.

Answer:

x = 16√3

y = 8√3

Step-by-step explanation:

First, to figure out x, put the side we already know (24) over the cosine of the angle we know (30).

x = 24/cos(30)

<em>(cos(30) is the same as √3/2)</em>

x = 24/√3/2

<em>Step 1: Multiply by 2/√3</em>

x = (24 * 2)/√3

<em>Step 2: Rationalize the denominator by multiplying by √3</em>

x = √3(24 * 2)/√3 * √3

<em>Step 3: √3 squared is 3.</em>

√3(24 * 2)/3

<em>Step 4: Multiply 24 by 2 to get 48.</em>

x = √3(48)/3

<em>Divide √3(48) by 3 to get 16√3</em>

x = 16√3

Before we figure out y, we need to find you what 16√3 squared is.

((16(√3))²

<em>Step 1: Expand the above equation.</em>

16²(√3)²

<em>Step 2: Square 16 to get 256.</em>

256(√3)²

<em>Step 3: √3 squared is 3.</em>

256(3)

<em>Step 4: Multiply 256 by 3 to get 768.</em>

768

Now, subtract 576 (24 squared) from 768 to get 192. Find the square root of that, which is 8√3. (192 = 8² * 3; rewrite as √8²√3, then take the square root of 8²
