The temperature on Monday is −4°C. On Tuesday, it is 13° colder. What is the temperature on Tuesday?(1 point)
Responses
−9°C
negative 9 degrees upper C
17°C
17 degrees upper C
9°C
9 degrees upper C
−17°C
negative 17 degrees upper C
The temperature on Tuesday would be -4°C minus 13°C, which equals -17°C.
So, the correct response is: −17°C (negative 17 degrees Celsius).
Ping dove off a 10 meter platform. He reached a depth of 6 meters in the water. What was the change in height?(1 point)

The change in height can be determined by subtracting the final height from the initial height. In this case, the initial height is 10 meters and the final height (depth in water) is 6 meters.
So, the change in height is: 10 meters - 6 meters = 4 meters.
Therefore, the correct response is: 4 meters.
A parasail is 1/20 of a meter above the water. Then, after 10 minutes, the parasail is 1/50 of a meter above the water. What is the change in height?(1 point)
Responses
The change in height can be determined by subtracting the final height from the initial height. In this case, the initial height is 1/20 of a meter and the final height is 1/50 of a meter.
So, the change in height is: (1/20) - (1/50) = (5/100) - (2/100) = (5-2)/100 = 3/100.
Therefore, the correct response is: 3/100 of a meter.

There are several possible contexts that could describe a difference of rational numbers. Some examples include:
1) In a mathematics problem, finding the difference between two rational numbers: For example, finding the difference between 3/4 and 1/3.
2) In a real-life situation, comparing the differences in measurements: For example, comparing the difference in weight between two objects, where the weights are represented by rational numbers.
3) In a statistical analysis, comparing the differences in data sets: For example, analyzing the difference in test scores between two groups of students, where the scores are represented by rational numbers.
