The context that describes a difference of rational numbers is:

comparing the daily high temperature and low temperature.

This involves calculating the difference between the two temperatures, which is a direct application of subtracting rational numbers.

To find the temperature on Tuesday, you need to subtract 13°C from Monday's temperature of -4°C.

The calculation is as follows:

\[ -4°C - 13°C = -4°C - 13°C = -17°C \]

So, 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 difference in height?(1 point)

64 meters

To find the difference in height between the platform and the depth Ping reached in the water, you can subtract the depth from the height of the platform:

The height of the platform is 10 meters, and the depth reached is 6 meters.

The difference in height is:

\[ 10 \text{ meters} - 6 \text{ meters} = 4 \text{ meters} \]

So, the difference in height is 4 meters.

To find the difference in height of the parasail, you need to subtract the initial height from the final height:

  1. Initial height: \( \frac{1}{20} \) kilometers
  2. Final height: \( \frac{1}{50} \) kilometers

First, we need to find a common denominator to subtract these fractions:

The least common multiple of 20 and 50 is 100.

Now, convert each fraction:

  • \( \frac{1}{20} = \frac{5}{100} \)
  • \( \frac{1}{50} = \frac{2}{100} \)

Now subtract the initial height from the final height:

\[ \frac{5}{100} - \frac{2}{100} = \frac{3}{100} \]

Thus, the difference in height is:

\( \frac{3}{100} \) kilometers.
