Answer:
-3 degrees F
Step-by-step explanation:
We are given that the previous night the temperature fell from 0 degree Fahrenheit to
[tex]-13 \frac{1}{5}[/tex]
Hence change in termperature is
[tex]-13 \frac{1}{5} =\frac{-66}{5}[/tex]
Time taken for this change is given as
[tex]4 \frac{2}{5}=\frac{22}{5}[/tex]}
Average rate of change per hour = temperature change /no of hours
The temperature drop per hour can be represented by
=-13 1/5 Divide 4 2/5
=[tex]\frac{-66}{5}[/tex] divided by [tex]\frac{22}{5}[/tex]
=-3 degree Fahrenheit
Answer:
The temperature drop per hour can be represented as [tex]3^{\circ}~F[/tex] or the temperature change per hour can be represented as [tex]-3^{\circ}~F[/tex]
Step-by-step explanation:
We are given the following information in the question:
Change in temperature:
[tex]\text{From }0 ~F \text{ to } -13\displaystyle\frac{1}{5}~F[/tex]
This fall in temperature too place in [tex]4\displaystyle\frac{2}{5} \text{ hours}[/tex]
Temperature drop per hour =
[tex]\displaystyle\frac{y_2-y_1}{\text{Time taken}}\\\\=\frac{-13\frac{1}{5}-0}{4\frac{2}{5}} = \frac{-13\frac{1}{5}}{4\frac{2}{5}}\\\\= \frac{\frac{-66}{5}}{\frac{22}{5}} = \frac{-66}{5}\times \frac{5}{22}\\\\=\frac{-66}{22} = -3^{\circ}~F[/tex]
The temperature change per hour can be represented as [tex]-3^{\circ}~F[/tex]
