Janiya found that her playlist will play for 3.8 x 10^2 seconds, 6.3 x 10^5 minutes, 1.05 x 10^4 hours, or 4.39814 x 10^2 days. Which answer uses the most appropriate units??
The answer that uses the most appropriate units would be 4.39814 x 10^2 days. Days are a larger unit of time compared to seconds, minutes, or hours, so it is more suitable for describing a playlist that lasts for a long period of time.
To determine which answer uses the most appropriate units, we need to compare the options given - seconds, minutes, hours, and days.
Let's start by converting all the given values to the same unit:
3.8 x 10^2 seconds = 380 seconds
6.3 x 10^5 minutes = 630,000 minutes
1.05 x 10^4 hours = 10,500 hours
4.39814 x 10^2 days = 439.814 days
Now, we can see that the option with the most appropriate units is 630,000 minutes.
To determine which answer uses the most appropriate units, we need to compare the given options and choose the one that represents the most reasonable timeframe for a playlist.
The options given are:
1. 3.8 x 10^2 seconds
2. 6.3 x 10^5 minutes
3. 1.05 x 10^4 hours
4. 4.39814 x 10^2 days
Let's convert each option into a single unit to compare them more easily.
1. 3.8 x 10^2 seconds = 380 seconds
2. 6.3 x 10^5 minutes = 630,000 minutes
3. 1.05 x 10^4 hours = 10,500 hours
4. 4.39814 x 10^2 days ≈ 439.814 days (rounded to three decimal places)
Now, it is clear that the most appropriate unit for the duration of a playlist is days, as it is a longer timeframe compared to seconds, minutes, and hours.
Therefore, the answer that uses the most appropriate units is 4.39814 x 10^2 days.
