On a number line, the surface of a river is marked at \(-220\) feet and the top of a building is marked at \(+19\) feet, where \(0\) represents sea level. What do \(-220\) and \(+19\) represent?

A. 220 feet below sea level and 19 feet above sea level
B. 220 feet above sea level and 19 feet below sea level
C. 220 feet below sea level and 19 feet above 220
D. 220 feet above sea level and 19 feet below 220

Answer :

On a number line, −220 represents 220 feet below sea level, and +19 represents 19 feet above sea level. The correct answer is option (A).

In the context of a number line where 0 represents sea level, the mark at −220 feet indicates a point that is 220 feet below sea level. This could be the depth of a river from the surface to the riverbed, for example. On the other hand, the mark at +19 feet indicates that the top of a building is 19 feet above sea level. So, the meanings of the given numbers are that −220 represents 220 feet below sea level and +19 represents 19 feet above sea level.

Thus, the correct answer to the student's question is option A) 220 feet below sea level and 19 feet above sea level

Answer:

A

Step-by-step explanation:

its A bc it said -220 witch is negative so that means ill be below sea level and +14 is a positive number so that will be above sea level.

Hope that helps!
