So you start by subtracting 3 from 35, which is 32. 32/8 = 4. So three years ago, Tim's son was 4 and Tim was 32. The percentage is about 13%
Answer: - x - 120
Explanation: You want to find the opposite of (120-x) not just x, so you just put the negative symbol next to both the variables.
Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s
4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m
5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m
6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m
9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m
