To find the change in temperature from the morning to the afternoon, we can subtract the morning temperature from the afternoon temperature.

1. Morning temperature: -9°F
2. Afternoon temperature: -2°F

Change in temperature = Afternoon temperature - Morning temperature
Change in temperature = -2°F - (-9°F)

This simplifies to:

Change in temperature = -2°F + 9°F
Change in temperature = 7°F

So, the change in temperature from the morning to the afternoon was 7°F.

To calculate Nora's score at the end of Level 1, we can start with her initial score and then account for the points she lost.

1. Points earned for passing inspection: +16 points
2. Points lost due to bridge collapse: -25 points

Now, we can calculate her final score:

Final score = Initial score + Points earned - Points lost
Final score = 16 + 16 - 25

This simplifies to:

Final score = 16 - 25
Final score = -9

So, Nora's score at the end of Level 1 was -9 points.

To find out how much higher Berlin is than Amsterdam, we can subtract the elevation of Amsterdam from the elevation of Berlin.

1. Amsterdam's elevation: -7 feet (below sea level)
2. Berlin's elevation: +112 feet (above sea level)

Now, we calculate the difference in elevation:

Difference in elevation = Berlin's elevation - Amsterdam's elevation
Difference in elevation = 112 - (-7)
Difference in elevation = 112 + 7
Difference in elevation = 119 feet

So, Berlin is 119 feet higher than Amsterdam.

To find the new elevation of Dean's drone after it dropped, we subtract the amount it dropped from its original elevation.

1. Original elevation: 307 feet
2. Drop in elevation: 59 feet

New elevation = Original elevation - Drop in elevation
New elevation = 307 feet - 59 feet
New elevation = 248 feet

So, the elevation of the drone now is 248 feet.
