To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of each song.
Number of songs: 1,900
Average time per song: 3.5 minutes
So, the total time for all songs in minutes would be:
1,900 songs * 3.5 minutes/song = 6,650 minutes
To convert minutes to seconds, we multiply by 60 (since there are 60 seconds in a minute):
6,650 minutes * 60 seconds/minute = 399,000 seconds
Expressing this in scientific notation to the exact decimal place, we get:
3.99 x 10^5 seconds
So the correct answer is "3.99 x 10^5 seconds".
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time per song.
The number of songs is 1,900.
The average time per song is 3.5 minutes, which is equivalent to 3.5 * 60 = 210 seconds.
To find the total number of seconds, we multiply these values: 1,900 * 210 = 399,000.
Rewriting this in scientific notation, we have 3.99 × 10^5 seconds.
Therefore, the correct answer is: 3.99 × 10^5 seconds.
To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of each song.
Given that Jim’s music library holds 1,900 songs and each song has an average time of 3.5 minutes, we can calculate the total time in minutes by multiplying these two values:
1,900 songs * 3.5 minutes/song = 6,650 minutes
However, the question asks for the answer in scientific notation, which means we need to convert the minutes to seconds. Since there are 60 seconds in a minute, we can convert minutes to seconds by multiplying by 60:
6,650 minutes * 60 seconds/minute = 399,000 seconds
Now, we can express this answer in scientific notation:
399,000 seconds = 3.99 × 10^5 seconds
So, the correct response is:
3.99 × 10^5 seconds.
