The amount of the final solution is 4 + 1 = 5 quarts.
The amount of alcohol in the final solution is 5 * 0.36 = 1.8 quarts.
The concentration of alcohol in the 4 quarts of alcohol solution that was added is:
Answer:
x1 = 3
Step-by-step explanation:
first set up the proportion (write as fractions):
(y1/x1) = (y2/x2)
then fill in the variables:
4/x1 = 8/6
now cross multiply:
8 • x1 = 6 • 4
simple algebra:
8 • x1 = 24
x1 = 24/8
x1 = 3
Answer:
D
Step-by-step explanation:
<u>The answer is D</u>. 6 is the whole number with no decimal after it so it goes before the decimal. Then we add the numbers after the decimal. 0.2 is the same as 0.20 so we add 0.20 plus 0.09 which gets us 0.29. Lastly, we add this all together and get a total of 6.29. Hope this helps!
