Answer: x = 12, y = 12\sqrt{3}

Step-by-step explanation:

A 30-60-90 triangle has sides whose lengths are related. (shown in the diagram attached) The longest side, the hypotenuse (opposite the right angle) represents 2x. The shortest side is x, and the last side is x\sqrt{3}.

We know the longest side = 24 = 2x.

If the shortest side is x, that means that the shortest side = the longest side DIVIDED by 2. Therefore, shortest side = x = 24/2 = 12 .

The last side is y and equals x\sqrt{3} . We now know that x = 12. Hence, y = 12\sqrt{3}.

The smelliness of cheese (denoted by S) can be defined as a function of the number of bacteria in the cheese (denoted by B) and
DedPeter [7]

Answer: OPTION C.

Step-by-step explanation:

Given the following formula:

S=B*A

You know that "S" is the smelliness of cheese, "B" is the number of bacteria in the cheese and "A" is the surface area in square centimeters of the cheese.

For example, suppose that there are 3,000\ bacterias in a surface area of 60 \ cm^2.

Substitute into the formula these values:

 B=3,000\ bacterias\\\\A=60\ cm^2

And then evaluate:

S=(3,000\ bacterias)(60\ cm^2)\\\\S=180,000\ bacterias*cm^2

Therefore, you can conclude that the appropriate measurement unit  for "S" is:

bacterias*cm^2
