Respuesta :
Answer:1.6 of a container of the fluid mustbe drained to make it 60% anti-freeze
Step-by-step explanation:
Answer: 1.6 quarts
Step-by-step explanation:
Given : A radiator contains 8 quarts of fluid, 40% of which is antifreeze.
[40% can be written as 0.40.]
Then, the amount of antifreeze in radiator = [tex]0.40\times8=3.2\text{ quarts}[/tex] (1)
If a radiator contains 8 quarts of fluid with 60% of which is antifreeze.
[60% can be written as 0.60.]
Then, the amount of antifreeze in radiator = [tex]0.60\times8=4.8\text{ quarts}[/tex] (2)
Now subtract (1) from (2) we get,
The amount of fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze :-
[tex]4.8-3.2=1.6\text{ quarts}[/tex]
Hence, the 1.6 quarts of fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze
