MOKL and mHKJ are vertical angles, so they’re congruent
so mHKJ is also 80°

An average adult can hear sounds with frequencies between 20 waves per second and 16,000 waves per second. What is the wavelengt

frez [133]

Answer:

The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.

Step-by-step explanation:

In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.

We know that the speed of light in air/ vacuum is $3\times 10^{8}$ .

Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,

we put the values

$3\times 10^{8}$ = 20 × λ

λ = $\frac{3\times 10^{8}}{20}$

λ = 15,000,000 m

Jorrel is wrong. 18 shots made out of the 40 shots attempted is 45%. 18 divided by 40 is 45% while 16 shots of him making it would have been a 40% of the shots out of 40 he took.
