Answer:
150 mL
Step-by-step explanation:
Let x represent the quantity of 75% solution needed. The total amount of alcohol in the 60% mixture will be ...
75%·x + 10%·45 = 60%·(x+45) . . . . . there will be x+45 mL of solution in the end
0.15x = 22.5 . . . . . . . . . . . . . . . . . . . . simplify, subtract .60x+4.5
22.5/0.15 = x = 150 . . . . . . . . . . . . . . mL of 75% solution needed
You will need 150 mL of the 75% solution.
It would be your first answer because since the MN is a positive you have to subtract it to move it to P and you solved for Q
292in^3
3x6x10=180 because I’ve split the shape in half
7x4x4=112
180+112=292
The answer could be D- pq. It's not from the center of the circle.
