Answer:
2x^2 - 3x - 1
Step-by-step explanation:
The answer to the problem is B.
Divide 100 by 48 and you should get how many people per percent, then multiply by 100 and boom.
You gave us the speed and the frequency, and you need the wavelength.
You were also nice enough to remind us that (fqy)x(lng) = speed.
So . . . F x W = 343 m/s
Divide each side by F :
W = (343 m/s) / F
W = (343 m/s) / (240 / s)
W = (343/240) m
<em>W = 1.429 meters</em>
