Answer:
The square root of a prime number is always an irrational number, then the product of the square root of a prime number and a nonzero rational number is equivalent to:
"the product of an irrational number and a rational number different than zero...."
We know that the product of an irrational number and a rational number (different than zero) is ALWAYS an irrational number.
Then "When is the product of the square root of a prime number and a nonzero rational number a rational number?"
Never, the product will always be irrational.

Step-by-step explanation:
To determine this, we need to set up proportions.
x/100 = 75/500.
A quick way to find x, the percentage we're looking for, is to cross multiply our fractions.
100 x 75 and 500 with x.
75 x100 = 7500, and 500 times x is 500x.
7500=500x
Divide by 500 on each side.
15 = x
Your answer is C.)15%.
I hope this helps!
The answer is c, because it is the same line, just higher.
Answer:
Ms. Cortez earns 500 dollars for working 30 hours. It's the last choice.
Step-by-step explanation:
You just have to substitute 30 into the equation in place of x, since x represents hours.
f(30) = 50 + 15(30)
f(30) = 50 + 450
f(30 = 500
