which context describes a difference of rational numbers?(1 point)
A. recording temperature hourly.
B. comparing the daily high temperature and low temperature.
C. finding the average of daily high temperatures.
D. determining the coldest temperature in a month.
B. comparing the daily high temperature and low temperature.
the temp on Monday is -4 degrees C. on Tuesday, it is 13 degrees colder. what is the temp on Tuesday?(1 point)
To find the temperature on Tuesday, we need to subtract 13 degrees from the temperature on Monday.
Given that the temperature on Monday is -4 degrees Celsius, subtracting 13 degrees gives us:
-4 degrees - 13 degrees = -17 degrees Celsius.
Therefore, the temperature on Tuesday is -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)
To find the change in height, we need to subtract the depth reached in the water from the initial height.
Given that Ping dove off a 10-meter platform and reached a depth of 6 meters, the change in height can be calculated as:
10 meters - 6 meters = 4 meters.
Therefore, the change in height is 4 meters.
a pairasnail is 1/20 of a meter above the water. then after 10 mins, the pairasnail is 1/50 of a meter above water. what changed in height?(1 point)
To find the change in height, we need to subtract the initial height from the final height.
The initial height of the pairasnail above water is 1/20 of a meter.
The final height of the pairasnail above water is 1/50 of a meter.
Therefore, the change in height can be calculated as:
1/50 - 1/20
To subtract fractions, we need to find a common denominator. The least common multiple (LCM) of 20 and 50 is 100.
1/50 can be written as 2/100.
1/20 can be written as 5/100.
Therefore, the change in height is:
2/100 - 5/100 = -3/100.
So, the change in height is -3/100 of a meter, meaning the pairasnail moved 3/100 of a meter below the initial height above the water.
