Question

1. if a submarine is 150 meters below sea level, what is the absolute value of its depth?

Explanation:

Step1: Define depth as negative value

The submarine's depth is $-150$ meters (since it is below sea level, we use a negative sign to represent this position relative to sea level).

Step2: Calculate absolute value

The absolute value of a number is its non-negative equivalent. For $x=-150$, the absolute value is $|-150| = 150$.

Answer:

150 meters
