Music: A band went to a recording studio and recorded 4 songs in 3 h.
How long would it take the band to record 9 songs if they record at the same rate?
5.5 h
6.25 h
3.25 h
6.75 h
please help mmeee
3/4 = .75 = x/9
Multiply both sides by 9.
thank you
so its 6.75??
Yep!
To solve this problem, we can use the concept of ratio and proportion.
First, we need to find the rate at which the band records the songs. We know that in 3 hours, they recorded 4 songs. So, the rate of recording is 4 songs/3 hours.
Next, we can set up a proportion to find out how long it would take to record 9 songs. Let "x" represent the time it takes to record 9 songs.
Proportion: 4 songs / 3 hours = 9 songs / x hours
Now we can cross-multiply and solve for "x":
4x = 3 * 9
4x = 27
x = 27 / 4
x ≈ 6.75 hours
Therefore, the answer is 6.75 hours.
