explaining a solution\nin july, the average temperature in one us city was 29°c. by december, the average temperature had fallen by 29°c. explain why the average temperature in december was 0°c.
Answer
Explanation:
Step1: Identify initial temperature
The initial average temperature in July is 29°C.
Step2: Identify temperature - change
The temperature has fallen by 29°C by December.
Step3: Calculate December temperature
We use subtraction. Let (T_{July}=29^{\circ}C) and the change (\Delta T=- 29^{\circ}C). The temperature in December (T_{December}=T_{July}+\Delta T). So (T_{December}=29+( - 29)=0^{\circ}C).
Answer:
The average temperature in December was (0^{\circ}C) because we start with an average temperature of (29^{\circ}C) in July and subtract (29^{\circ}C) (since the temperature has fallen by (29^{\circ}C)), and (29 - 29=0).
