True, because energy, frequency, and wavelength are all properties of sound, and sound is an electromagnetic wave. The electromagnetic spectrum encompasses a continuous range of frequencies or wavelengths of electromagnetic radiation, ranging from long wavelength, low energy radio waves to short wavelength, high frequency, high energy gamma rays.
If 30% of his collection is 12 cars, then we can use the fraction
30/12=100/x
x=40
Answer:
y=6/5x+11
Step-by-step explanation:
Perpendicular lines have the opposite sign and reciprocal of the original line. Since the y-intercept is 11 we know that it is 6/5x+11
3*2=6
6-x-2=0
4=x
The answer is 4
