Arecording of the current weather conditions last 3/4 minute. if the recording plays repeatedly , how many times would it play in 1 hour?

The recording repeated  plays 80 times in 1 hour

Step-by-step explanation:

A recording last mins

Let x be the number of times it repeats in 1 hour

Using ratio and proportion,

But

This implies that

Hence the recording repeatedly  plays 80 times in 1 hour

im not sure

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
