Question

The statement below describes a situation in which opposite quantities combine to make zero: A cup with a hole in it loses 2 ounces of water in the first minute and then loses 2 ounces of water in the second minute.

True

False

Answer 1

False

Explanation:

A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means

Add -2 (loses ⇒ means getting less)

Then the cup loses 2 ounces of water in the second minute. This mathematically means

Add -2 (loses ⇒ means getting less)

In total,

`(-2)+(-2)=-4\\eq 0`

and means loses 4 ounces in two minutes.

Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false
