The concentration of solution would be the amount of the molecule divided by the volume. In this case, the solution concentration is 36% and the volume is 4 quarts + 1 quarts= 5 quarts. You are asked the concentration before 1 quarts added. The alcohol content should be same for both solutions. The answer should be:

concentration = alcohol content/ volume
alcohol content =concentration * volume
alcohol content1 =alcohol content2
36% * 5 quarts = concentration2 * 4quarts
concentration2= 36% * 5 quarts / 4 quarts= 45%

Drupady [299]

You have not provided the options, but this solution is an equation that will work:

Step-by-step explanation:

      Since the total material is 4 feet long, we can divide 4 feet by 7, the number of equal pieces cut, to see how long each piece is.

If you need to provide a wrap for a rice and meat mixture, you would most likely use cabbage or _______ leaves.
taurus [48]
You would most likely use lettuce leaves, because grapes are little orbs of fruit with no leaves, zuchini are funny shaped veggies, and hibiscus is a type of tree. So, the most logical answer would be lettuce leaves.

Answer:

  See below

Step-by-step explanation:

The solution choices all agree that x = 1±√2. The second equation tells you ...

  y = ±2√(x+2)

so the sign of the √2 term in x is the same as the sign of the √2 term in y. The answer choices circled in red are the ones that meet this requirement.
