Respuesta :
45 times
1 hour = 60 minutes
60 multiplied by 3/4 = 180/4 = 45
1 hour = 60 minutes
60 multiplied by 3/4 = 180/4 = 45
Answer:
The recording repeated plays 80 times in 1 hour
Step-by-step explanation:
A recording last [tex]\frac{3}{4}[/tex] mins
Let x be the number of times it repeats in 1 hour
Using ratio and proportion,
[tex]1\:time=\frac{3}{4} mins\\ x\:times=1\: hour[/tex]
But [tex]1\:hr=60\:mins[/tex]
This implies that
[tex]1\:time=\frac{3}{4} mins\\ x\:times=60\: mins[/tex]
[tex]\frac{3}{4}x=60[/tex]
[tex]x=\frac{4\times60}{3}[/tex]
[tex]x=80\:times[/tex]
Hence the recording repeatedly plays 80 times in 1 hour
