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
It would be 7 because if you multiple 6 you get 1
You use sine, cosine, or tan
Answer:
80
Step-by-step explanation:
1 centimeter is equal to 20 feet so if you have 4 cm, it's will 4*20
Also the other two answers are too small to be possible
