Mechanical Advantage = Force by Hammer / Force by Nail = 160/40 = 4
Alright so
Surface area = (width x height) + (length x width) + (length x height) + (length x side)
Answer:
greater than 1
Step-by-step explanation:
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
