A band's first song is 4 minutes, 12 seconds long and has 462 beats.

The band wants to have a second song that is 3 minutes, 54 seconds long with the same beats per minute as the first song.

There would be total beats in the second song

18

Step-by-step explanation:54 divided by 3

There would be  429  total beats in the second song. (i hope this helps)

Step-by-step explanation:

The number of beats is proportional to the time of the song.  Convert the time to seconds to avoid recurring decimals.

4  minutes  12  seconds =  4×60+12=  252  seconds

3  minutes  54  seconds =  4×60−6=234  seconds

X/234  =462/252  

X= 234 x 462

         252

X= 429

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
