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.
To find the total number of seconds, we need to multiply the number of songs by the average time of each song in minutes.
Number of songs = 1,900
Average time of each song = 3.5 minutes
Total time in minutes = Number of songs x Average time of each song
= 1,900 x 3.5
= 6,650 minutes
To convert this to seconds, we need to multiply the total time in minutes by 60, as there are 60 seconds in a minute.
Total time in seconds = Total time in minutes x 60
= 6,650 x 60
= 399,000 seconds
Using scientific notation, the total number of seconds the playlist will play is 3.99 x 10^5 seconds.
To find the total number of seconds Jim's 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 of each song = 3.5 minutes
To convert minutes to seconds, we multiply by 60 since there are 60 seconds in a minute.
Total number of seconds = 1,900 songs * 3.5 minutes/song * 60 seconds/minute
Calculating this gives:
Total number of seconds = 1,900 * 3.5 * 60
Total number of seconds = 399,000
Expressing the answer in scientific notation:
Total number of seconds = 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.
First, let's convert the average time of each song from minutes to seconds. We know that 1 minute is equal to 60 seconds. So, 3.5 minutes can be written as:
3.5 minutes * 60 seconds/minute = 210 seconds
Now, let's find the total number of seconds by multiplying the number of songs by the average time:
1,900 songs * 210 seconds/song = 399,000 seconds
To express this answer in scientific notation, we move the decimal point to the left until there is only one digit to the left of the decimal point, and then multiply it by a power of 10.
399,000 seconds = 3.99 × 10^5 seconds
So, the total number of seconds the playlist will play is 3.99 × 10^5 seconds.
