The question is asking for 1/3 of Molly’s length, which is 20 inches. The word of in this context indicates multiplication, which means you should multiply 20 by 1/3.
1/3 x 20 = 6.666666 (repeating) or 6.7 (rounded)
Therefore, Molly is 6.7 inches tall.
Answer:
Wednesday
Step-by-step explanation:
it is the lowest number
We begin with 100 mL of the 2% saline solution, and will add x mL of the 0.5% saline solution. The total volume of the mixture will be (100 + x) mL. The total mass of salt will be:
(100)(2%) + (x)(0.5%) = 2 + 0.005x
This would have to be 0.79% of the total volume:
(100+x)(0.79%) = 0.79 + 0.0079x
Equating:
x = 417.24 mL
