The temperature on Monday is −4°C. On Tuesday, it is 13° colder. What is the temperature on Tuesday?
To find the temperature on Tuesday, we need to subtract 13° from the temperature on Monday.
Temperature on Monday: -4°C
Temperature on Tuesday: -4°C - 13°C = -17°C
Therefore, the temperature on Tuesday is -17°C.
Ping dove off a 10 meter platform. He reached a depth of 6 meters in the water. What was the change in height?
To find the change in height, we need to subtract the initial height from the final depth.
Initial height: 10 meters
Final depth: 6 meters
Change in height: Initial height - Final depth
Change in height: 10 meters - 6 meters = 4 meters
Therefore, the change in height 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?
To find the change in height, we need to subtract the initial height from the final height.
Initial height: 1/20 of a meter
Final height: 1/50 of a meter
Change in height: Final height - Initial height
Change in height: (1/50) - (1/20)
To subtract fractions, we need a common denominator. So we find the least common denominator (LCD), which is 100 in this case.
(1/50) - (1/20) = (2/100) - (5/100) = -3/100
Therefore, the change in height is -3/100 of a meter.
