15 answers
Change in temperature = final temperature - initial temperature
Change in temperature = 22°F - (-13°F)
Change in temperature = 35°F
Next, we can calculate the average change in temperature per hour by dividing the total change in temperature by the number of hours:
Average change in temperature per hour = change in temperature / time interval
Average change in temperature per hour = 35°F / 7 hours
Average change in temperature per hour = 5°F/hour
Therefore, the average change in temperature per hour was 5°F.
Average change in temperature per hour = (final temperature - initial temperature) / time interval
Using the values from the problem, the equation becomes:
Average change in temperature per hour = (22°F - (-13°F)) / 7 hours
Simplifying:
Average change in temperature per hour = 35°F / 7 hours
Then, the final answer is:
Average change in temperature per hour = 5°F/hour
A mountain climber on Mt. Everest is at 29,035 ft above sea level. A stone at the bottom of the Dead Sea is at 1,349 ft below sea level. What is the difference in elevation between the mountain climber and the stone?
Difference in elevation = climber's elevation + stone's elevation
Difference in elevation = 29,035 ft + 1,349 ft
Difference in elevation = 30,384 ft
Therefore, the difference in elevation between the mountain climber on Mt. Everest and the stone at the bottom of the Dead Sea is 30,384 feet.
Difference in elevation = climber's elevation + stone's elevation
Using the values from the problem, the equation becomes:
Difference in elevation = 29,035 ft + (-1,349 ft)
Simplifying:
Difference in elevation = 30,384 ft
Therefore, the difference in elevation between the mountain climber on Mt. Everest and the stone at the bottom of the Dead Sea is 30,384 feet.
A deep-sea diver must descend and ascend in short steps to equalize pressure on his body. If the diver rises toward the surface too fast, he may suffer from a physical condition called “the bends.” Suppose the diver started at 82 feet below the surface and rose in five steps of 15 feet each. Use an integer to describe his new position in relation to the water surface.
After the first step, the diver will be at a depth of:
82 - 15 = 67 feet below the surface
After the second step:
67 - 15 = 52 feet below the surface
After the third step:
52 - 15 = 37 feet below the surface
After the fourth step:
37 - 15 = 22 feet below the surface
After the fifth and final step:
22 - 15 = 7 feet below the surface
Therefore, the diver's new position in relation to the water surface is 7 feet below the surface.
An elevator on the 10th floor goes down 9 floors. Then it goes up 19 floors, down 3, and finally down 12. What floor does it end up on? Write an equation to show how you found your answer.
Net change in floors = down 9 floors + up 19 floors + down 3 floors + down 12 floors
Simplifying:
Net change in floors = -9 + 19 - 3 - 12
Net change in floors = -5
This means that the elevator ended up 5 floors down from its starting position on the 10th floor.
To find the final floor, we can subtract 5 from the starting floor of the elevator:
Final floor = starting floor - net change in floors
Final floor = 10 - (-5)
Final floor = 15
Therefore, the elevator ends up on the 15th floor.
The equation used to find the final floor is:
Final floor = starting floor - (down 9 floors + up 19 floors + down 3 floors + down 12 floors)
Substituting the values from the problem, the equation becomes:
Final floor = 10 - (-9 + 19 - 3 - 12)
Simplifying:
Final floor = 10 - (-5)
Final floor = 15.
The temperature in your town is 31°F. The radio announcer says that the temperature will drop 15 degrees. What will the temperature be? Write an equation to show how you found your answer.
New temperature = initial temperature - temperature drop
New temperature = 31°F - 15°F
New temperature = 16°F
Therefore, the temperature will be 16°F after the drop of 15 degrees.
The equation used to find the new temperature is:
New temperature = initial temperature - temperature drop
Substituting the values from the problem, the equation becomes:
New temperature = 31°F - 15°F
Simplifying:
New temperature = 16°F
New temperature = initial temperature - temperature drop
Using the values from the problem, the equation becomes:
New temperature = 31°F - 15°F
Simplifying:
New temperature = 16°F
Therefore, the equation for finding the new temperature is:
New temperature = 31°F - 15°F
Or simply:
New temperature = 16°F
