a weather forecaster predicts that the temperature will drop 3 degrees each hour for the next 9 hours. If the temperature is 7 degrees farenheit before the temperature starts falling, what is the temperature after the drop?
Given : Temperature before drop is 7 degrees farenheit and the tempetature drops by 3 degrees.
Therefore, tempetature after the drop is (7 degrees farenheit - 3 degrees farenheit) = 4 degrees farenheit.
Note: Predicted drop is 3 degrees each hour.
Neg 20
To find the final temperature after the drop, we need to subtract 3 degrees for each of the 9 hours.
Since the temperature is initially 7 degrees Fahrenheit, we can calculate the temperature after 9 hours by subtracting (3 * 9) from 7.
The formula to calculate the final temperature is: Final Temperature = Initial Temperature - (Rate of change * Time)
In this case, the initial temperature is 7 degrees Fahrenheit, the rate of change is 3 degrees per hour, and the time is 9 hours.
Using the formula, we can solve the equation:
Final Temperature = 7 - (3 * 9)
Final Temperature = 7 - 27
Final Temperature = -20
Therefore, after the temperature drops 3 degrees per hour for the next 9 hours, the final temperature will be -20 degrees Fahrenheit.
3 * 9 = 27
7 - 27 = -_____
