Answer:

10 quarts orange juice.

Step-by-step explanation:

Marissa bought $2(1)/(2)$ gallons of orange juice to make punch.

We have to calculate how many quarts of orange juice Marissa should buy.

Since 1 gallon = 4 quarts of liquid

So 2.5 gallons = 2.5×4 = 10 quarts of juice

Therefore Marissa will require 10 quarts of orange juice to buy.

PLEASE HELP with these math questions (Please don't answer if you don't know all of them)

sqrt (53) = 10 * sqrt (0.53)

0.53 = 64/121
sqrt (0.53) = sqrt (64)/ sqrt (121) = 8/11 = 0.7273
Therefore sqrt (53) = 10 * 0.7273 = 7.27

sqrt (108) = 10 * sqrt (1.08)
sqrt (1.08) = sqrt (676/625) = 26/25 = 1.04
Therefore sqrt (108) = 10 * 1.04 = 10.4

sqrt (128) = 10 * sqrt (1.28)
sqrt (1.28) = sqrt (289/225) = 17/15 = 1.133
Therefore sqrt (108) = 10 * 1.133 = 11.33

Evaluate a÷b a=6.4 and b =0.08

Answers

For this problem, you simply have to plug in a and b into your equation. By this I mean that you have to replace a and b in the first equation with what they tell you. Since a=6.4 and b=0.08, you just have to change the first equation to 6.4÷0.08. You can then solve it out and you will end up getting an answer of 80.
