3.45 acres
solution :
3.75+3.75= 7.5
7.5-2.9 = 4.6
4.6×.25= 1.15
4.6-1.15= 3.45
A. because it followes the rule, C and B do not
Answer:
- Part A Option B
- Part B 5.71 l and 4.29 l
Step-by-step explanation:
<h3>Part A</h3>
Let x be the volume of 5% solution
<u>Then the volume of 40% solution is </u>
<u>Amount of acid is 10*0.20 for resultant solution, x*0.05 for 5% solution and (10- x)*0.40 is for 40% solution:</u>
- 10*0.20 = x*0.05 + (10 - x)*0.40
Correct equation is B.
<h3>Part B</h3>
<u>Solving</u>
- 2 = 0.05x + 4 - 0.4x
- 0.35x = 2
- x = 2/0.35
- x = 5.71 l of 5% solution
and
- 10 - x = 10 - 5.71 = 4.29 l of 40% solution
