The speed of sound is 346 m/s. if a sound wave travels at a frequency of 55 hz, what would its wavelength be

6.29 meters.

Step-by-step explanation:

The formula to find the wavelength is given by :-

, where v is the speed of wave and f is the frequency of wave.

We are given that ,

The speed of sound is 346 m/s.

i..e v=346 m/s

A sound wave travels at a frequency of 55 H.

i..e f=55 Hz

Then, the  wavelength =

Hence, the wavelength would be 6.29 meters.

the correct answer is 5

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
