To find the total number of seconds the playlist will play, we need to multiply the number of songs by the duration of each song in seconds.
Number of songs: 1,900
Duration of each song: 3.5 minutes = 3.5 * 60 seconds = 210 seconds
Total number of seconds = Number of songs * Duration of each song = 1,900 * 210 = 399,000 seconds
In scientific notation, 399,000 can be expressed as 3.99 × 10^5 seconds.
Therefore, the 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 per song.
The total number of songs is 1,900 and the average time per song is 3.5 minutes.
First, convert the average time per song from minutes to seconds:
3.5 minutes x 60 seconds/minute = 210 seconds
Now, multiply the total number of songs by the average time per song:
1,900 songs x 210 seconds/song = 399,000 seconds
Expressing this answer in scientific notation, we have:
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 of each song.
There are 1,900 songs in Jim's music library, and each song has an average time of 3.5 minutes.
First, let's convert the average time from minutes to seconds. Since there are 60 seconds in a minute, we can multiply 3.5 minutes by 60 to get the average time in seconds:
3.5 minutes × 60 seconds/minute = 210 seconds
Now, we can multiply the number of songs by the average time to find the total number of seconds the playlist will play:
1,900 songs × 210 seconds = 399,000 seconds
Expressed in scientific notation, 399,000 seconds can be written as 3.99 × 10^5 seconds.
So, the correct answer is:
3.99 × 10^5 seconds
