Question

1. no calculator: a ham is placed in a freezer. every 5 minutes, the internal temperature changes by $-1\frac{1}{2}$ degrees. what is the change in temperature after 40 minutes? represent the temperature change as an integer.

Explanation:

Step1: Calculate the number of 5 - minute intervals

The total time is 40 minutes. The number of 5 - minute intervals \(n=\frac{40}{5}\)
\(n = 8\)

Step2: Calculate the temperature change

The temperature change per 5 - minute interval is \(-1\frac{1}{2}=-\frac{3}{2}\) degrees.
The total temperature change \(T=n\times(-\frac{3}{2})\)
Substitute \(n = 8\) into the formula: \(T=8\times(-\frac{3}{2})\)
\(T=-12\)

Answer:

\(-12\)
