A diver is 25 feet below sea level. After he swims up 15 feet toward the surface, what is his elevation? 50 feet below sea level

50 feet above sea level

10 feet above sea level

10 feet below sea level

The diver is 25 feet below sea level. Then he swims 15 up toward the surface. We can do 25 - 15 = 10. His elevation is 10 feet below sea level.

Step-by-step explanation:

I represent "below sea level" as negative numbers, so 25 ft below sea level would be a -25 ft. Since the diver swims up, or increases by 15 ft, I'd add that.

-25 + 15 = - 10

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
