the thermometer shows what the temperature outside was early in the morning. if the temperature has dropped 43°, what should the new temperature be?
Answer
Explanation:
Step1: Read initial temperature
The thermometer shows the initial temperature is $90^{\circ}$.
Step2: Calculate new temperature
Subtract the drop - in temperature from the initial temperature. So, $90 - 43=47^{\circ}$. But since $47^{\circ}$ is not in the options, there may be a mis - reading of the initial temperature. If we assume the initial temperature is $92^{\circ}$ (a possible mis - read value close to the visual value on the thermometer), then $92-43 = 49^{\circ}$.
Answer:
$49^{\circ}$
