Question

4 The size 4 soccer ball Sean's team uses should weigh

Answer 1

Most 2 balls could weigh = 0.74 kilograms, Least 2 balls could weigh = 0.62 kilograms

Step-by-step explanation:

Maximum weight of soccer ball = 0.37 kilogram

Minimum weight of soccer ball = 0.31 kilogram

One bag has two balls

1. To find out the most weight, we need to assume that both balls are of the maximum weight so,

Weight of ball 1 + Weight of ball 2

0.37 + 0.37

= 0.74 kilograms

2. To find out the least weight, we need to assume that both balls are of the minimum weight so,

Weight of ball 1 + Weight of ball 2

0.31 + 0.31

= 0.62 kilograms

The weight of two balls are

$\leq 0.74 kilograms$

$\geq 0.62 kilograms$

Therefore, the most these two balls could weigh together is 0.74 kilograms and the least these two balls could weigh together is 0.62 kilograms.
