How many quartz of pure antifreeze must be added to 6 quartz of a 10 percent antifreezesolution to obtain a 20 percent antifreeze solution?
4.2 quarts
How many ml of 15 percent solution are needed to make 1 gal of 2.5 percent solution?
(X gal)(0.15) = (1 gal)(0.025)0.15X = 0.025X = 0.17 gallons (4 quarts/1 gal.)(1 liter/1.06 quarts)(1000 ml/1 liter)= 642 milliliters============
How many quarts of 6 percent butterfat milk and 1 percent butterfat milk should be mixed to yield 75 quarts of 4 percent butterfat milk?
If 'X' is the number of quarts of 6 percent butterfat milk and 'Y' is the number of quarts of the 1 percent butterfat milk then: x + y = 75 quarts and (6x + 1y)/75 = 4 (because we want 4 percent per quart) then solving for the system of equations leads to: x = 45 quarts (the 6 percent) and y = 30 quarts (the 1 percent)
What is 20 percent of 12 quarts?
20% of 12 quarts= 20% * 12= 0.2 * 12= 2.4 quarts or 76.8 ounces (US measure)
How many quarts of water must be added to 4 quarts of an 80 percent mixture to obtain a 50 percent mixture?
To find out how many quarts of water must be added, we first calculate the amount of pure substance in the 80 percent mixture. In 4 quarts of an 80 percent mixture, there are 3.2 quarts of the substance (0.8 x 4). Let ( x ) be the amount of water added. The total volume after adding water will be ( 4 + x ) quarts, and we want this to equal a 50 percent concentration, which gives the equation ( 3.2 = 0.5(4 + x) ). Solving for ( x ) gives ( 3.2 = 2 + 0.5x ), resulting in ( 0.5x = 1.2 ), or ( x = 2.4 ). Therefore, 2.4 quarts of water must be added.
A car's radiator has a capacity of 15 quarts and it currently contains 12 quarts of a 30 percent antifreeze solution. How many quarts of pure antifreeze must be added to strengthen the solution 40 per?
The original solution has 3.6 quarts of antifreeze in it. The equation then becomes (3.6 + x)/(12 + x) = 0.40, where x is the amount of antifreeze added. X is then equal to 2.

How many quarts of pure antifreeze must be added to 4 quarts of a 20 antifreeze solution to obtain a 40 antifreeze and solution?
You need 1 1/3 quarts of pure antifreeze.
How many quarts of pure antifreeze must be added to 5 quarts of 20 percent antifreeze to make a 30 percent antifreeze solution?
In the original solution, you have 5 quarts total, 20% antifreeze. So 20% * 5 = 1. You have 4 qt water and 1 qt antifreeze. You will add an amount A, to this mixture. When you add, the new total volume (in quarts) is 5 + A, and the percentage is:(1 + A)/(5 + A) x 100%. So when you start out at A = zero, you have 1/5 x 100% = 20%.So set up the equation (1 + A)/(5 + A) * 100 = 30, and solve for A.Multiply both sides by (5+A) and isolate the term A. Note that since you are adding, the value of A will never be negative (so you don't have to worry about the denominator (5+A) being zero.Answer = 5/7 (quarts) = 0.714285714285155 quarts.
How much pure 100 percentage antifreeze should be added to five quarts of 20 percentage solution to raise its concentration to 25 percentage antifreeze solution?
I'd go buy a bottle of pre-mixed antifreeze, and just fill it up with that. Less hassle, works great.
