The amount of salt is in the 350 g of feta cheese, when there is 35% of salt is in cheese, is 122.5 grams.
<h3>What is percentage of a number?</h3>
Percentage of a number is the part of the whole number which is expressed in the fraction of hundredth. It is represented with "%" symbol.
35% of salt is in feta cheese. The percentage of salt is in that 350 g cheese has to be found out.
Let suppose there is x grams of slat in feta cheese of 350 g. Thus, the amount of salt (35% of 350) is,
Thus, the amount of salt is in the 350 g of feta cheese, when there is 35% of salt is in cheese, is 122.5 grams.

Answer:
25%
Step-by-step explanation:
Answer:
[-3, ∞)
Step-by-step explanation:
There are many ways to find the range but I will use the method I find the easiest.
First, find the derivative of the function.
f(x) = x² - 10x + 22
f'(x) = 2x - 10
Once you find the derivative, set the derivative equal to 0.
2x - 10 = 0
Solve for x.
2x = 10
x = 5
Great, you have the x value but we need the y value. To find it, plug the x value of 5 back into the original equation.
f(x) = x² - 10x + 22
f(5) = 5² - 10(5) + 22
= 25 - 50 +22
= -3
Since the function is that of a parabola, the value of x is the vertex and the y values continue going up to ∞.
This means the range is : [-3, ∞)
Another easy way is just graphing the function and then looking at the range. (I attached a graph of the function below).
Hope this helped!
I'm gonna say C )
We have to multiply the number outside the parenthesis by the numbers inside.
