Step-by-step explanation:
a whole circle is 360°.
if you take away 40°, how many are left ?
that is absolutely the same as the question, when I have 15 apples and 6 are eaten, how many are left ?
well, 15-6 = 9 apples are left.
and so, 360-40 = 320° are left.
Answer:
You'll need 2.8 gallons of the 80% solution.
Step-by-step explanation:
Let the volume of 30% alcohol =x gallons
Then the volume of 80% alcohol =(14-x) gallons
Since we want to obtain a 40% alcohol solution, we have:
0.3x+0.8(14-x)=0.4(14)
0.3x+11.2-0.8x=5.6
0.8x-0.3x=11.2-5.6
0.5x=5.6
x=11.2
Therefore, the volume of 80% alcohol
=14-11.2
=2.8 gallons
You'll need 2.8 gallons of the 80% solution.
