Well lets look at this
First figure out: How many milliliters are in a liter: 1000
Ok now you need half a liter so how would you figure out how many milliliters that is?
Divide by 2: 1000 ÷ 2 = 500
So 500 milliliters are needed for half a liter
28.38 / 3.3 = 8.75
She makes $8.75 per hour
Answer:
depends on where you get it.
$4.79
Step-by-step explanation:
Answer:
x1 = √(509) /100 + 3/10
x2 = -√(509) /100 + 3/10
Step-by-step explanation:
We do completing the square as follows:
1. Put all terms with variable on one side and the constants on the other side.
5x^2 - 3x = 25
2. Factor out the coefficient of the x^2 term.
5(x^2 - 3x/5) = 25
3. Inside the parentheses, we add a number that would complete the square and also add this to the other side of the equation. In this case we add 9/100 and on the other side we add 9/20.
5(x^2 - 3x/5 + 9/100) = 25 + 9/20
4. We simplify as follows:
5(x^2 - 3x/5 + 9/100) = 25 + 9/20
5(x - 3/10)^2 = 509/20
(x - 3/10)^2 = 509/100
x1 = √(509) /100 + 3/10
x2 = -√(509) /100 + 3/10
