Question

ben has a jar weighing 236g. when he puts his collection of 36 identical marbles inside the jar, the combined weight of the jar and the marbles is 1.281kg. what is the weight of each marble? give your answer as a decimal.

Answer 1

29.03g

Explanation:

The total mass of the jar and marbles combined is 1.281kg, or 1281g. Subtract the mass of the jar from this to find the total mass of the marbles (1281g - 236g = 1045g). Then, divide this number by 36 to find the mass of each marble (1045g / 36 = 29.03g).
