Answer:
92.
Step-by-step explanation:
By proportion the mass of zinc = (345/ 15) * 4
= 92.
Answer:
x intercepts -sqrt(5), + sqrt(5)
y intercept -5
Step-by-step explanation:
y = x^2 -5
to find the x intercept set y=0 and solve for x
0 = x^2-5
add 5 to each side
5 = x^2
take the square root of each side
+- sqrt(5) = sqrt(x^2)
x = +-sqrt(5) there are 2 x intercepts since it is a quadratic
to find the y intercept set x=0 and solve for y
y = 0-5
y = -5
To find a percent, you use this simple formula:
5000/62000 = x/100
In this case, x is going to be your percent of commission.
So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.
Now your equation looks like this:
0.08 = x/100
Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:
8 = x
So, the answer is 8%.
