## How many gallons of a 90% antifreeze solution must be mixed with gallons of antifreeze to get a mixture that is antifreeze use the six step method?

400 gallons of 90% antifreeze solution must be mixed with 80 gallons of 30% antifreeze to get a mixture that is 80% antifreeze.

## How many gallons of a 90% antifreeze solution must be mixed with 90 gallons of 20% antifreeze to get a mixture that is 80% antifreeze?

SOLUTION: How many gallons of a 90% antifreeze solution must be mixed with 90 gallons of 15% antifreeze to get a mixture that is 80% antifreeze? Use the six step method. It will be a lot, because the final result is 80%. They add to 540.

**How many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 20% antifreeze to get a mixture that is 60% antifreeze?**

25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water). You will add ‘x’ gallons of 70% antifreeze to make the 60% mixture.

**How many gallons of a 80% antifreeze solution must be mixed with 90 gallons of 20% antifreeze to get a mixture that is 70% antifreeze use the six step method?**

How much of 80% antifreeze do we need to add to make a 70% solution? x = 450 gallons of 80% must be added to make a 70% solution.

### How many gallons of a 80% antifreeze solution must be mixed with 80 gallons of 20% antifreeze to get a mixture that is 70% antifreeze use the six step method?

Question 715759: How many gallons of a 80% antifreeze solution must be mixed with 80 gallons of 25% antifreeze to get a mixture that is 70% antifreeze? X=360 GALLONS OF 80% ANTIFREEZE IS USED.

### How many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 10% antifreeze to get a mixture that is 60% antifreeze?

25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water). You will add ‘x’ gallons of 70% antifreeze to make the 60% mixture. So, at the conclusion, you will have (90+x) gallons 60% ‘pure’ antifreeze.

**How many gallons is an 80 antifreeze solution?**

you would need 550 gallons of 80% antifreeze solution.

**How many gallons of a 80% antifreeze solution must be mixed with gallons of antifreeze to get a mixture that is antifreeze?**

600 gallons of 80% antifreeze solution should be used for the mixture.

#### How many gallons of a 70% antifreeze solution must be mixed with 70 gallons of 10% antifreeze to get a mixture that is 60% antifreeze?

SOLUTION: how many gallons of 70% antifreeze solution must be mixed with 60 gallons of 10% antifreeze to get a mixture that is 60% antifreeze. x=300 gal. of 70% anti freeze is used.

#### How many gallons of a 80% antifreeze solution must be mixed with 70 gallons of 30% antifreeze to get a mixture that is 70% antifreeze use the six step method?

Solving for x, the answer is 240 gallons!

**How many gallons of a 80% antifreeze solution must be mixed with 60 gallons of 30% antifreeze to get a mixture that is 70% antifreeze?**

(3) Since the mixture percentage is 4 times as close to 80 as it is to 30, the amount of the 80% ingredient must be 4 times the amount of the 30% ingredient. That’s it. There are 60 gallons of the 30% antifreeze, so the number of gallons of 80% antifreeze must be 4*60 = 240.

**How many gallons of 80% antifreeze solution must be mixed with 80 gallons of 30% antifreeze to get a mixture that is 70% antifreeze?**

## How many gallons of 80% antifreeze must be?

SOLUTION: How many gallons of a 80% antifreeze must be mixed with 70 gallons of 25% antifreeze to get a mixture of 70% antifreeze You can put this solution on YOUR website! . .

## Is it better to mix antifreeze with water?

A higher antifreeze to water ratio may be beneficial in cold weather because of its lower freezing point ratio, while a lower antifreeze to water mixture will have improved cooling effect in hot weather.

**How to reduce the concentration of coolant in a car?**

If the concentrated coolant volume is too high, substitute water instead of coolant to add to the system to bring it into line. So, instead of adding 3 liters of antifreeze to a concentration of 75/25 antifreeze to water concentration, you would add 3 liters of water to reduce the concentrated coolant amount.

**How to calculate the percent of bleach in a gallon of water?**

So if you want to know how much bleach to add to a gallon of water to make a 10% disinfectant solution, we’re here to help. Keep in mind that if you are wanting a 1%, 2% (etc) percent solution and want to be as precise as possible, you should subtract the amount of solute you will be adding from the solution.
