the temperature in Alaska dropped by -5.7 degrees every hour for 3.5 hours.if the temperature started at 23 degrees f,what temperature was it at the end of the 3.5 hours?
To find the temperature at the end of 3.5 hours, we need to calculate the change in temperature over that period of time.
The temperature dropped by -5.7 degrees every hour, and the total time period is 3.5 hours.
To calculate the total change in temperature, we multiply the rate of change (-5.7) by the number of hours (3.5):
-5.7 degrees/hour * 3.5 hours = -19.95 degrees
Since the temperature started at 23 degrees Fahrenheit, we need to subtract the change from the initial temperature:
23 degrees - 19.95 degrees = 3.05 degrees
Therefore, at the end of the 3.5 hours, the temperature in Alaska was approximately 3.05 degrees Fahrenheit.
To find the temperature at the end of the 3.5 hours, we need to calculate the change in temperature first.
The temperature in Alaska dropped by -5.7 degrees every hour for 3.5 hours. So, the total change in temperature would be (-5.7 degrees/hour) * (3.5 hours).
Let's calculate that:
Change in temperature = (-5.7 degrees/hour) * (3.5 hours)
Change in temperature = -19.95 degrees
Now, to find the temperature at the end of the 3.5 hours, we need to subtract the change in temperature from the starting temperature.
End temperature = Starting temperature - Change in temperature
Given:
Starting temperature = 23 degrees Fahrenheit
Change in temperature = -19.95 degrees Fahrenheit
Substituting the values:
End temperature = 23 degrees Fahrenheit - (-19.95 degrees Fahrenheit)
End temperature = 23 degrees Fahrenheit + 19.95 degrees Fahrenheit
End temperature = 42.95 degrees Fahrenheit
Therefore, at the end of the 3.5 hours, the temperature in Alaska would be approximately 42.95 degrees Fahrenheit.
how do you drop by -5.7°
Maybe you mean either
it dropped by 5.7°
or, it changed by -5.7°
In that case, after 3.5 hours, the change is clearly -5.7 * 3.5°
So, add that to the starting 23°, and what do you get?
