Answer:
66 gallons
Step-by-step explanation:
Given that initially 160 gallons of a solution containing 12% salt.
So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.
Let x gallons of water get evaporated so that the remaining solution contains 20% salt.
The remaining amount of solution = 160-x gallons.
As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so
19.2 = 20% of (160-x)
gallons
Hence, 66 gallons of water must be evaporated to get a 20% salt solution.
Answer:
1 3/5
Step-by-step explanation:
The drip rate can be written as a proportion, where d is the daily drip volume.
(2/3 gal)/(10 h) = d/(24 h)
Multiplying by 24, we have ...
d = (2/3 gal)·(24/10) = 48/30 gal = 1 3/5 gal
1 3/5 gallons of water drip per day.
Of two angles and the included side of one triangle are congruent to the corresponding to the corresponding parts of another triangle hen the triangles are congruent. I really don't think there is additional information to prove if the triangles are congruent by using ASA.

Answer:
Step-by-step explanation:12
To solve for variable h flip the equation. You get: 12gh=f. After, divide both sides by 12 to get your answer: h=f/12g
