Jim’s music library on his phone holds 1,900 songs. The songs have an average time of 3.5 minutes. Use scientific notation to find the total number of seconds the playlist will play. Express the answer to the exact decimal place.(1 point) Responses 0.399×10^6 seconds 0.399 times 10 superscript 6 baseline seconds 3.99×10^4 seconds 3.99 times 10 superscript 4 baseline seconds 3.99×10^5 seconds 3.99 times 10 superscript 5 baseline seconds 3.99×10^3 seconds 3.99 times 10 cubed seconds
To find the total number of seconds the playlist will play, we need to multiply the total number of songs by the average time of each song in minutes and then convert the result to seconds.
Total number of songs: 1,900
Average time of each song: 3.5 minutes
Total time in minutes: 1,900 songs * 3.5 minutes = 6,650 minutes
Converting minutes to seconds: 6,650 minutes * 60 seconds = 399,000 seconds
Expressing this in scientific notation: 3.99 x 10^5 seconds
Therefore, the correct answer is 3.99 x 10^5 seconds.
