About 400 zebras live at the game reserve.

The proportion would be 
30/150 = 80/x

This is because 30 zebras are tagged out of 150 in one area.  We know that they tagged 80 total zebras out of x total zebras.

To solve this, cross multiply:
x*30 = 150*80
30x = 12000

Divide both sides by 30:
30x/30 = 12000/30
x = 400

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.
Vaselesa [24]

<u>Answer:</u> The wavelength for X-rays with the given frequency is 1\times 10^{-10}m

<u>Step-by-step explanation:</u>

To calculate the wavelength of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light  

c = speed of light = 3\times 10^8m/s

\nu = frequency of light = 3\times 10^{18}s^{-1}

Putting the values in above equation, we get:

\lambda=\frac{3\times 10^8m/s}{3\times 10^{19}s^{-1}}=1\times 10^{-10}m

Hence, the wavelength for X-rays with the given frequency is 1\times 10^{-10}m
