Answer:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
Step-by-step explanation:
We know that the temperature of the freezer is never greater than -2°C. Yesterday the temperature was -10°C but it increased at a steady rate of 1.5°C per hour. We calculate how long in hours and minutes did the temperature increase inside the freezer.
We conclude that the difference in temperature is 8°C.
We get:
We conclude that it took 5 hours and 20 minutes for the freezer to reach that temperature.
The percent of the continental states primarily in the Eastern time zone isless than the percent of all states that are in the Mountain or Central time zone.
Step-by-step explanation:
Step 1:
In order to determine the percentages of the given zones first, we need to determine the total number of states that are being taken into count.
The total number of zones
There are 51 states in total.
Step 2:
The number of states in the eastern time zone is 21.
The percent of states in the eastern time zone
There are 7 states in the Mountain time zone and there are 16 states in the central time zone.
So the percent of states in the mountain time zone or the central time zone
So the percent of the continental states primarily in the Eastern time zone is less than the percent of all states that are in the Mountain or Central time zone.
