c. what would your elevation be if you were standing near the ocean?
2. ocean water freezes at about -2 1/2 c. fresh water freezes at 0c. antifreeze, a liquid use to cool car engines, freezes at -64 c. imagine that the temperature is exactly at the freezing point for ocean water. how many degrees must the temperature drop for the antifreeze to turn to ice?
3. rosa ran 1/3 of the way from her home school. she ran 1/4 mile. how far is it between her home and school?

The answer to your question is below

Step-by-step explanation:

1. Denver, Colorado is called "The Mile High City" because its elevation is 5280 feet above sea level. Someone tells you that the elevation of Death Valley, California is -282 feet.  

a. Is Death Valley located above or below sea level? Explain  Below see level, because we use (-) to indicate that something is being measure below sea level and (+) to indicate that is above sea level.

b. How many feet higher is Denver than Death Valley?  

5280 - (-282) = 5280 + 282 = 5562 ft

c. What would your elevation be if you were standing near the ocean?

Zero feet.

2. Ocean water freezes at about -2 1/2 C. Fresh water freezes at 0C. Antifreeze, a liquid use to cool car engines, freezes at -64 C. Imagine that the temperature is exactly at the freezing point for ocean water. How many degrees must the temperature drop for the antifreeze to turn to ice?

It would be   -64°C -2.5°C = -61.5°C

3. Rosa ran 1/3 of the way from her home school. She ran 1/4 mile. How far is it between her home and school?

The answer is    1/4 mile is 1/3 of the distance from her home to school

                          then,  3(1/4) = 3/4 mile is the distance
