Question

on a friday morning, the temperature was 67F the temperature dropped 6f and then rose 10f how much does the temperature need to rise or fall to return to the initial temperature of 67F
A. fall 4F
B. rise 6F
C. fall 10F
D. rise 4F

Answer 1

Let's break down the temperature changes step by step:

1. Initial temperature: 67°F
2. Temperature drops by 6°F:
\( 67°F - 6°F = 61°F \)
3. Temperature rises by 10°F:
\( 61°F + 10°F = 71°F \)

Now, to determine how much the temperature needs to change to return to the initial temperature of 67°F:

Current temperature: 71°F
To return to 67°F:
\( 71°F - 67°F = 4°F \)

Since the current temperature of 71°F is higher than 67°F, the temperature needs to fall by 4°F.

So the answer is:
**A. fall 4F**
