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 = (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 = (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 :-
Hence, the 1.6 quarts of fluid should be drained and replaced with pure antifreeze so that the new mixture is 60% antifreeze
Answer:
The options 2,3 and 5 are correct.
Step-by-step explanation:
From the figure it is noticed that the points U,V and W are midpoint of JK,KL and JL respectively.
Midpoints theorem of triangle states that the line connecting the midpoints of two sides is parallel to third side and its length is half of the third side.
The points U and W are midpoint of JK and JL. Using midpoint theorem, we get
The points U and V are midpoint of JK and KL. Using midpoint theorem, we get
The points V and W are midpoint of KL and JL. Using midpoint theorem, we get
Therefore options 2, 3 and 5 are correct.
