A scuba diver is 30 ft below sea level. Which of the following best describes this situation?
1. |30|
2. |-30|
3. -30
4. ±30

Respuesta :

Answer is #3. -30
Reason
1 and 2 are absolute values so they are 30, the 4th answer is plus or minus, the question says “below sea level” which is a negative number so it is -30.
