Answer:
18432 km/h
Step-by-step explanation:
It is given that a sound wave travels through iron at a rate of 5120 m/s.
We know that
1 km = 1000 m
1 hour = 60 minutes
1 minutes = 60 second
Using these conversions we get
1 m = 0.001 km
1 hour = 3600 second


Therefore, the sound wave travels through iron at a rate of 18432 km/h.
Answer:
Step-by-step explanation:
Well 6 to the second power is when you multiply 6 x 6 = 36
And ab= -320
180 - 70 = 110
110 - 35 = 75
The third angle is 75
