Write the number with appropriate signs: 150 m below sea level.a)-150b...
Answer:
To represent the number 150 m below sea level, we use a negative sign "-". Therefore, the appropriate sign for 150 m below sea level is -150.
Explanation:
Sea level is a reference point used to measure the height or depth of a location. When a location is below sea level, it means that its elevation is negative. In this case, since the location is 150 m below sea level, the number is negative.
The options provided are:
a) -150
b) 150
c) 200
d) None of these
Among these options, the correct answer is option 'A' (-150).
Let's analyze the given options:
a) -150: This option represents a negative number, indicating that the location is below sea level.
b) 150: This option represents a positive number, which means the location is above sea level. It does not accurately represent the given situation.
c) 200: This option represents a positive number, indicating the location is above sea level. It does not accurately represent the given situation.
d) None of these: This option implies that none of the given options accurately represent the number 150 m below sea level.
Therefore, the correct answer is option 'A' (-150), as it is the only option that represents a number below sea level.
