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.
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.
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.
