A valley is 94 feet below sea level. what is the absolute value of the elevation difference between the valley and the sea level? write the problem and evaluate.
Problem: Find the absolute value of the elevation difference between a valley that is 94 feet below sea level.
Evaluation: The absolute value of a number is its distance from zero on a number line. In this case, we want to find the distance between the elevation of the valley and sea level, which is the height of zero on our number line. To do this, we need to take the absolute value of -94:
| -94 |= 94
Therefore, the elevation difference between the valley and sea level is 94 feet.
