To find the change in temperature between −20°F and 30°F, you can subtract the two temperatures:

Change in temperature = Final temperature - Initial temperature
Change in temperature = 30°F - (-20°F)

When you subtract a negative number, it's the same as adding that number:

Change in temperature = 30°F + 20°F
Change in temperature = 50°F

So, the change in temperature between −20°F and 30°F is **50°F**.

Yes, that's correct! The change in temperature between −20°F and 30°F is **50°F**.

To find the new temperature after a drop of 8°F from an initial temperature of −5°F, you can subtract 8 from −5:

New temperature = Initial temperature - Drop in temperature
New temperature = -5°F - 8°F

When you subtract 8 from −5, you get:

New temperature = -5°F - 8°F = -13°F

So, the temperature now is **-13°F**.
Answered by GPT-4o mini
Yes, that is correct! If the temperature was −5°F this morning and it dropped by 8°F, the new temperature is indeed **-13°F**.

To find the new position of the submarine after it ascends 200 feet from its current depth of 650 feet below sea level, you need to add the 200 feet to -650 feet (the submarine's current position).

New position = Current position + Ascent
New position = -650 feet + 200 feet

Now, let's calculate:

New position = -650 + 200 = -450

So, the integer that represents its new position is **-450**.
Answered by GPT-4o mini
Yes, that is correct! If the Navy submarine is 650 feet below sea level and ascends 200 feet, its new position would indeed be **-450 feet**.
