You are asked to prepare 234 mL of acetic acid that has concentration of 41%. There is a supply of 45% saline solution available and 32% saline solution available. How
many millilitres of the 45% and how many millilitres of the 32% acetic acid should be
mixed to create the 234 mL of the 41% mixture?
Your

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

step-by-step explanation:

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
