How many gallons of a 80 percent solution must mix with 70 gallons of 10 percent solution to get 70 percent solution?
420 gallons. Here's how to find it; If X = Gallons of 80% mix, 0.8*X + 0.1*70 = 0.7*(X+70) Which we can then solve, 0.8X + 7 = 0.7X + 49 0.1X = 42 X = 420

How many gallons of a 80 percent antifreeze solution must be mixed with 70 gallons of 30 percent antifreeze to get a mixture that is 70 percent antifreeze?
if z is the answer then you are going to end with (70 + z) gallons of solutionto find out what z is you use this formula: .8z + (70 x .3) = .7(z + 70)this yields: .8z - .7z = 49 - 21.1z = 28 or z = 280 gallonsnote that decimals are used for the percent values-- 80% = .8 etc
How many gallons of a 80 percent antifreeze solution must be mixed with 70 gallons of 20 percent antifreeze to get a mixture that is 70 percent antifreeze?
70 gallons of 20% solution contains 70*0.2 = 14 gallons of antifreeze. Suppose you need G gallons of the 80% antifreeze solution. This will contain 0.8*G gallons of antifreeze. Total volume of solution = G + 70 gallons Volume of antifreeze required in this solutions to make it a 70% solution is 0.7*(G + 70) = 0.7G + 49 gallons. Volume of antifreeze = 14 + 0.8G gallons So 0.7G + 49 = 14 + 0.8G 0.7G + 35 = 0.8G 35 = 0.1G 350 = G Answer: 350 gallons.
How many gallons of a 50 percent antifreeze solution must be mixed with 70 gallons of 30 percent antifreeze to get a mixture that is 40 percent antifreeze?
70gallons
How many gallons of a 70 percent solution must be mixed with 70 gallons of 10 percent antifreeze to get a mixture that is 60 percent antifreeze?
Say x = total gallons of solution at 60%Say y = gallons of 70% solutionx=70+y gallonsThen .60x = .70y + .1(70)substituting for x gives.60(70) + .60y = .70y + .1(70) or42 + .6y = .7y + 7 or42-7 = .1y gives y = 350 gals and x = 420 gals total solutionThe answer is 350 gallons
