The temperature is 8° F. As a cold front moves in, the temperature drops 6° F per hour. What is the temperature at the end of 3 hours?
–26°F
–10°F
5°F
26°F
–26°F
–10°F
5°F
26°F
The temperature drops 6° F per hour, so after 3 hours, the temperature will have dropped 6° F * 3 hours = 18° F.
Starting from 8° F, if we subtract 18° F, we get 8° F - 18° F = -10° F.
Therefore, the temperature at the end of 3 hours is -10°F.
Starting from 8° F, if we subtract 18° F, we get 8° F - 18° F = -10° F.
Therefore, the temperature at the end of 3 hours is -10°F.
Which situation results in a final value of zero?
the overall change in temperature when the temperature goes from to 10°F to –10°F
the total profit made when a person buys an item for $2 and then sells the item for $2
the overall change in altitude of a hot air balloon after rising 21 km from sea level
the total distance a person travels when he bikes 3 miles to school and then 3 miles back home from school
the overall change in temperature when the temperature goes from to 10°F to –10°F
the total profit made when a person buys an item for $2 and then sells the item for $2
the overall change in altitude of a hot air balloon after rising 21 km from sea level
the total distance a person travels when he bikes 3 miles to school and then 3 miles back home from school
The situation that results in a final value of zero is:
the total profit made when a person buys an item for $2 and then sells the item for $2
In this case, the profit is $2 - $2 = $0, resulting in a final value of zero.
the total profit made when a person buys an item for $2 and then sells the item for $2
In this case, the profit is $2 - $2 = $0, resulting in a final value of zero.
