When Alvin woke up in the morning, it was

Question

–
9°F. By the afternoon, the temperature had risen to
–
2°F.
What was the change in temperature from the morning to the afternoon?

Answer 1

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.

Answer 2

Nora loves to play the Bridge Builders video game, where players gain and lose points by building safe and unsafe bridges. In Level 1, Nora earned 16 points because her bridge passed inspection. Then, she lost 25 points because part of her bridge collapsed!
What was Nora's score at the end of Level 1?

Answer 3

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.

Answer 4

The city of Amsterdam, in the Netherlands, is 7 feet below sea level. The city of Berlin, in the neighboring country of Germany, is 112 feet above sea level.
How much higher is Berlin than Amsterdam?

Answer 5

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.

Answer 6

Dean was flying his drone at an elevation of 307 feet. A strong gust of wind then caused it to drop 59 feet.
What is the elevation of the drone now?

Answer 7

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.
