jim's music library on his phone holds 1,900 songs. the songs have an average time of 3.5 minutes long. use scientific notation to find the total number of seconds the playlist will play. express the answer to the exact decimals place
To find the total number of seconds the playlist will play, we multiply the number of songs by the average time of each song in minutes and then convert it to seconds.
1,900 songs * 3.5 minutes/song = 6,650 minutes
To convert minutes to seconds, we multiply by 60:
6,650 minutes * 60 seconds/minute = 399,000 seconds
Expressed in scientific notation with the exact decimal place, the total number of seconds the playlist will play 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 in minutes, and then convert it to seconds.
The number of songs in Jim's music library is 1,900.
The average time of each song is 3.5 minutes.
To convert minutes to seconds, we multiply by 60 since there are 60 seconds in a minute.
So, the total number of seconds the playlist will play is:
1,900 songs * 3.5 minutes/song * 60 seconds/minute
= 1,900 * 3.5 * 60 seconds
= 399,000 seconds
To express this answer in scientific notation to the exact decimal place, we can write it as:
3.99 x 10^5 seconds
To find the total number of seconds the playlist will play, we need to calculate the product of the number of songs and the average time of each song.
First, let's convert the average time of each song from minutes to seconds. There are 60 seconds in one minute, so 3.5 minutes is equal to 3.5 * 60 = 210 seconds.
Next, we can multiply the number of songs by the average time of each song to find the total number of seconds:
Total number of seconds = 1,900 songs * 210 seconds/song
Multiplying these values together, we get:
Total number of seconds = 399,000 seconds
To express this answer in scientific notation, we can write 399,000 as 3.99 * 10^5.
Therefore, the total number of seconds the playlist will play, expressed in scientific notation to the exact decimal place, is 3.99 * 10^5 seconds.
