dimulka [17.4K]

Answer:

429 beats

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

Set up a direct proportion using equivalent fractions:

x234=462/252

   ←beats/←seconds

x=234×462/252

x=429 beats

murzikaleks [220]

Answer:

The required value for the blank is 21.8696

Step-by-step explanation:

Consider the provided information,

4,275.50= 391/2 of ____

Replace blank with x.

4,275.50 = 391/2 of x

Use sign of multiplication for "of".

4,275.50 = \frac{391}{2} \times x

Solve the above expression for x.

x=\frac{4,275.50\times 2}{391}

x=21.8696

Thus, the required value for the blank is 21.8696
