Question

The size 4 soccer ball Sean's team uses should weigh no more than 0.37 kilogram, and no less than 0.31 kilogram. A soccer bag has two balls in it.

Will three soccer balls weigh more than 1 kilogram? Explain.

Answer 1

Three soccer balls could weigh more than 1 kilogram if each weighs the maximum of 0.37 kg, totaling 1.11 kg, but if they weigh the minimum of 0.31 kg, the total would be 0.93 kg and thus less than 1 kg.

Step-by-step explanation:

To determine if three soccer balls will weigh more than 1 kilogram, we must consider the weight range of a size 4 soccer ball. The weight of each ball is no more than 0.37 kilograms and no less than 0.31 kilograms. If we take the maximum weight possible for each ball, three balls would weigh 3 x 0.37 kg = 1.11 kg. Even considering the minimum weight, three balls would weigh 3 x 0.31 kg = 0.93 kg.

Therefore, it is possible that three soccer balls could weigh slightly more than 1 kilogram if each ball weighs the maximum of 0.37 kg. However, if each ball weighs at or near the minimum of 0.31 kg, then the total weight of three soccer balls would be less than 1 kilogram.
