The correct keyword that shows finding the difference between rational numbers is "subtract." So the correct answer is "D) subtract."
I apologize for the confusion. The keyword "compare" in option "B) compare" can also indicate finding the difference between rational numbers, as it implies a comparison between two quantities. Thank you for pointing that out, and I apologize for any misunderstanding caused.
To find the balance in the account, we need to subtract the fee from the initial balance.
Initial balance: -$11
Fee: $25
To calculate the balance, we can use the equation:
Balance = Initial balance - Fee
Balance = -$11 - $25
Balance = -$36
Therefore, the balance in the account is -$36.
To find the water level at the end of summer, we need to add the drop during the summer to the initial water level.
Initial water level: 1 1/2 meters below sea level
Drop during summer: 2 1/3 meters below sea level
To add the drop to the initial water level, we can use the equation:
Water level at the end of summer = Initial water level + Drop during summer
Water level at the end of summer = 1 1/2 - 2 1/3
To perform the subtraction, we need to find a common denominator for 2/3 and 1/2, which is 6.
Water level at the end of summer = (3/2) - (4/6)
= (9/6) - (4/6)
= 5/6
Therefore, the water level at the end of summer is 5/6 meters below sea level.
To find the difference in rainfall between June and July, we need to subtract the amount of rainfall in July from the amount of rainfall in June.
Rainfall in June: 2.3 inches above normal
Rainfall in July: 1.2 inches below normal
To calculate the difference in rainfall, we can use the equation:
Difference in rainfall = Rainfall in June - Rainfall in July
Difference in rainfall = 2.3 - (-1.2)
To subtract the negative value, we can change it to a positive value by adding it.
Difference in rainfall = 2.3 + 1.2
= 3.5
Therefore, the difference in rainfall between June and July is 3.5 inches.
To find how far the submarine traveled, we need to calculate the difference between its depth after 5 hours and its initial depth.
Initial depth: 106.3 feet below sea level
Depth after 5 hours: 481.2 feet below sea level
To calculate the distance traveled, we can use the equation:
Distance traveled = Depth after 5 hours - Initial depth
Distance traveled = 481.2 - 106.3
Distance traveled = 374.9
Therefore, the submarine traveled a distance of 374.9 feet.
The context that describes a difference of rational numbers is "comparing the daily high temperature and low temperature".
The scenario that represents finding the difference in books is "finding the number of books remaining after a sale on books".
To find the temperature on Tuesday, we need to subtract 13 from the temperature on Monday.
Temperature on Monday: -4°C
Change in temperature: 13° colder
To calculate the temperature on Tuesday, we can use the equation:
Temperature on Tuesday = Temperature on Monday - Change in temperature
Temperature on Tuesday = -4°C - 13°C
Temperature on Tuesday = -17°C
Therefore, the temperature on Tuesday is -17°C.
To find the change in height, we need to subtract the initial height of the parasail from the final height.
Initial height: 1/20 of a meter
Final height: 1/50 of a meter
To calculate the change in height, we can use the equation:
Change in height = Final height - Initial height
Change in height = 1/50 - 1/20
To perform the subtraction, we need to find a common denominator for 1/50 and 1/20, which is 100.
Change in height = (2/100) - (5/100)
Change in height = -3/100
Therefore, the change in height is -3/100 of a meter.

What number added to −70 has a sum of zero?(1 point)
To find the number that, when added to -70, gives a sum of zero, we need to determine the additive inverse or the opposite of -70.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
In this case, the additive inverse of -70 is 70.
Therefore, 70 added to -70 gives a sum of zero.
Carson has moved back 3 spaces in a game. What must be the next turn to move back to the original position?(1 point)
To move back to the original position after moving back 3 spaces, Carson needs to move forward by the same amount.
Since Carson moved back 3 spaces, he needs to move forward 3 spaces to return to the original position. Thus, the next turn must be to move forward by 3 spaces.
Morgan has 20 points in a game. What value can be added to 20 points to get a sum of 0?(1 point)
bot?
Apologies for the confusion. To get a sum of 0 by adding a value to 20 points, we need to add the additive inverse or the opposite of 20.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero. In this case, the additive inverse of 20 is -20.
Therefore, -20 can be added to 20 points to get a sum of 0.
Nicolas plays two rounds of golf. In the first round, he scores 3 under par, and he scores 3 over par for the second round. Are these opposite quantities whose sum is 0? Respond 1 if these quantities are opposites. Respond 2 if these quantities are not opposites.
These quantities are not opposites. They represent different deviations from par in golf. One is 3 under par, while the other is 3 over par. Opposites would be a score of 3 under par and a score of 3 under par, or a score of 3 over par and a score of 3 over par. Thus, the correct response is 2.
it was 1
Apologies, you are correct. These quantities are indeed opposites. A score of 3 under par and a score of 3 over par are opposite because they represent deviations in opposite directions from the par score. Therefore, the correct response is 1.
One town is 20 feet above sea level. Another town is 10 feet below sea level. Are these opposite quantities whose sum is 0? Respond 1 if these quantities are opposites. Respond 2 if these quantities are not opposites.(1 point)
These quantities are not opposites. Opposites would be if one town is 20 feet above sea level and the other is 20 feet below sea level, or if one town is 10 feet above sea level and the other is 10 feet below sea level. In this case, one town is above sea level and the other is below sea level, but their magnitudes are not equal. Therefore, the correct response is 2.

To find the change in height, we need to subtract the depth reached in the water from the height of the platform.
Height of the platform: 10 meters
Depth reached in the water: 6 meters
To calculate the change in height, we can use the equation:
Change in height = Height of the platform - Depth reached in the water
Change in height = 10 meters - 6 meters
Change in height = 4 meters
Therefore, the change in height is 4 meters.
