Given:
A solution of 60% fertilizer is to be mixed with a solution of 21% fertilizer to form 234 liters of a 43% solution.
To find:
The quantity of the 60% solution in the mixture.
Solution:
Let x be the quantity of the 60% solution and y be the quantity of the 21% solution.
Quantity of mixture is 234. So,
...(i)
The mixture has 43% fertilizer. So,
Multiply both sides by 100.
...(ii)
Using (i) and (ii), we get
Divide both sides by -39.
Putting this value in (i), we get
Therefore, 132 liters of the 60% solution must be used.
Answer:
Step-by-step explanation:
Width = x
Length = 2x
Area of the ground = 0.125 square mile
length * width = 0.125
2x * x = 0.125
2x² = 0.125
x² =
= 0.0625
Width = 0.25 miles
Length = 2* 0.25 = 0.50 miles
