Answer:
You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 60% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.6x + y)/320 = 0.65 ⇒ 0.6x + y = 208
x + y = 320
Solving the sistem of equations:
x = 280 and y = 40
Therefore, You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.
Multiply with 25
25*5 quarts +25*1 pints +25*6 oz
125 quarts +25 pints +150 oz
Answer:
<h3>Midpoint = (-3 ,-9)</h3>
Step-by-step explanation:
Length = 60 feet
Perimeter = 220 feet
There's four sides to a rectangle if one side is 60 then that means there are two sides that 60 because they are opposite each other.
So side A=60 and side B = 60
Now you have two sides left. Add the two sides you have to get 120
Subtract 120 from 220 = 100
Now divide 100 by 2 to get the remainder side lengths which is 50
So side C=50 and side D=50
Area is base times height so in this case it would be 50 times 60 since those are adjacent sides
And your answer is 3000 feet
