when a cold front move through, the temperature dropped at an average of 3 degree per hour.using a signed number find the change in temperature after six hours
6(-3) = -18
To find the change in temperature after six hours, we need to multiply the rate of temperature drop by the number of hours. In this case, the rate of temperature drop is 3 degrees per hour, and we want to find the change in temperature after six hours.
Using signed numbers, we need to consider the direction of the change. Since the temperature is dropping, we use negative numbers to represent the decrease in temperature. Therefore, the rate of temperature drop is -3 degrees per hour.
Now, let's calculate the change in temperature after six hours using the formula:
Change in temperature = Rate of temperature drop * Number of hours
Change in temperature = -3 degrees/hour * 6 hours
Change in temperature = -18 degrees
So, after six hours, the temperature dropped by an average of 18 degrees (in the negative direction).
