I don’t get this :(
muminat
Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)


So first we need to convert the mixed number to an improper fraction


1 4/5 = 9/5


Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers


Your answer is 18/5 I hoped this help



Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21


The last one is the same steps we did for the first one which is 27/20



I hoped this helped you it is a little difficult but you’ll get the hang of it :)

PLEASE HELP WILL MARK BRAINLIEST The frequency f​ (in waves per​ second) and the wavelength w​ (in meters) of a sound traveling
marshall27 [118]

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>
