Suppose 6 pints of a 28% alcohol solution is mixed with 4 pints of a 90% alcohol solution. What is the concentration of alcohol
in the new 10-pint mixture?
The concentration of alcohol in the new 10-pint mixture is 3%.
1 answer:
Answer:
52.8%
Step-by-step explanation:
The amount of alcohol is:
0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints
So the concentration is:
5.28 pints / 10 pints × 100% = 52.8%.

Answer:
y = -1
Step-by-step explanation:
A horizontal line is of the form
y =
The y coordinate of the point (-2,-1) is -1
The equation is y = -1
since it's rhombus, then
6x-11=25-4x
10x=36
x=3.6
each side = 25-4(3.6)
= 25 - 14.4
= 10.6
