The correct answer is B) 1/2 mL.
Adding the amounts that are currently in each beaker, we have:
1/8 + 1/4 + 3(3/8) + 2(3/4) + 1
= 1/8 + 1/4 + 9/8 + 6/4 + 1
Converting all of these to fractions with common denominators, we have:
1/8 + 2/8 + 9/8 + 12/8 + 8/8 = 32/8 = 4 mL of liquid total.
We have 8 beakers to split up 4 mL of liquid; 4/8 = 1/2.
Answer: Multiply
2 * 1 5/6
Convert 1 5/6 into an improper fraction:
2 * 11/5
Multiply:
22/5
Convert to mixed number:
4 2/5
So 22/5 or 4 2/5 of a pan of brownies was left.
Use Pythagoras theorem
(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2
H^2 = B^2 + P^2
