Question

1. the record high temperature on january 15 is 41.5°f. the record low temperature on that day is -16.8°f. what is the difference in the record temperatures?

Explanation:

Step1: Recall the formula for temperature difference

To find the difference between the high temperature (\(H\)) and low temperature (\(L\)), we use the formula \( \text{Difference}=H - L \). Here, \(H = 41.5^\circ\text{F}\) and \(L=- 16.8^\circ\text{F}\).

Step2: Substitute the values into the formula

Substituting the values, we get \( \text{Difference}=41.5-(-16.8) \). When subtracting a negative number, it is equivalent to adding the positive of that number, so \(41.5 - (-16.8)=41.5 + 16.8\).

Step3: Perform the addition

Adding \(41.5\) and \(16.8\), we have \(41.5+16.8 = 58.3\).

Answer:

The difference in the record temperatures is \(58.3^\circ\text{F}\).
