Bill, a health food enthusiast, is mixing concoctions in his basement. He's invented a new drink that needs to be 40% carrot juice and 60% other stuff. He has been to the store and has found some concentrated carrot juice (60% carrot juice). His neighbor Clara, who decided one day that she doesn't like carrot juice that much anymore, has contributed 80 quarts of 12% carrot juice. How many quarts of the concentrated carrot juice does he need to add to the 80 quarts of weak juice to produce his perfect drink with 40% carrot juice

112

Step-by-step explanation:

We have to:

x is the number of quarts of 60% juice required.

We also know that pure carrot juice in 60% juice (0.6 * x) added to the amount of pure carrot juice in 12% juice 9.6 (0.12 * 80) has to be equal to the amount of carrot juice pure in the final mixture (0.4 * (80 + x)).

Therefore numerically it is the following:

0.6 * x + 9.6 = 0.4 * (80 + x)

Solving for x, we are left with:

0.6 * x + 9.6 = 32 + 0.4 * x

0.6 * x-0.4 * x = 32-9.6

0.2 * x = 22.4

x = 22.4 / 0.2

x = 112

That is, 112 quarts of 60% juice are required.

answer: your gay

step-by-step explanation:

you dont know math

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
