Answer:
4.5 g 56.25 g Since the only type of measurement mentioned in this question is weight or mass, I'll assume that the percentage concentration is % m/m (mass/mass). For that type of concentration measurement, simply multiple the percentage by the total mass to get the mass of the desired substance. So 150 g * 3% = 150 g * 0.03 = 4.5g For the amount of 8% solution with the same amount of dry substance, there's 2 ways of calculating the mass of solution. First, use the ratio of percentages, multiplied by the mass of the original solution to get the desired amount of new solution: 3/8 * 150 g = 56.35 g Or calculate it from scratch, like 4.5/X = 8/100 450/X = 8 450 = 8X 56.25 = X In both cases, the result is that you desire 56.25 grams of 8% solution.

Step-by-step explanation:
1 i believe because its the only one that says "more than". The other two say less than.
(x + 2)(x - 5)(x - 8)
Substitute them into each other to get the whole equation)
1 cm = 10 mm
1 x 44 = 10 x 44
44 cm = 440 mm
Joseph's new puppy is 440 mm (cute!).
