Answer:
A. you need 2 1/2 ounces
B. you need 73,9 milliliters
Step-by-step explanation:
A
We have the ratio 1/2 ounces per gallon
And the mop bucket holds 5 gallons
Then we need to multiply 1/2*5
we got 2 1/2 ounces of desifectant per 5 gallons
B
1 ounces equal 29,57 milliliters
if we have 2 1/2 ounces then we multiply 2,5 *29,57
the answer is 73,9 milliliters
(x+1) (x+3)
the zeroes of the function are negative 1 and negative 3
Answer:
8x2-30x+27 has one root (9/4) the square of the other (3/2)
Step-by-step explanation:
8x2+30x+27 = (2*x+3)*(4*x+9) => solution = {-3/2, -4/9}
One is not the square of the other because squares are positive.
8x2-30x+27 = (2*x-3)*(4*x-9) =>
solution = {3/2, 4/9} since (4/9 = (3/2)^2, therefore the preceding question is correct.
The answer for number one is -3.938.
