It's A) to find the slope.
The resulted equation is in slope-intercept form which gives the slope (-A/B).
Step-by-step explanation:
The frequency of a radio wave that has a wavelength of 3000m is 100 kHz
(a) Wavelength = 500 m
We know that,
![f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{500}\\\\f=600\ kHz](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7Bc%7D%7B%5Clambda%7D%5C%5C%5C%5Cf%3D%5Cdfrac%7B3%5Ctimes%2010%5E8%7D%7B500%7D%5C%5C%5C%5Cf%3D600%5C%20kHz)
(b) Frequency, f = 800 kHz
![\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{800\times 10^3}\\\\\lambda=375\ m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bc%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B3%5Ctimes%2010%5E8%7D%7B800%5Ctimes%2010%5E3%7D%5C%5C%5C%5C%5Clambda%3D375%5C%20m)
Hence, this is the required solution.
Answer:
2/5 = 4/10
4/10 = 40%
Explanation:
2/5 is a simplified fraction, and one of the bigger fractions it’s made by 4/10. Do you can use 4/10, but can also use 8/20, 20/50, 40/100, so on. Since we know that any fraction that of ten can be turned into a percentage easily (2/10=20%, 5/10=50%,9/10=%90), then 4/10 is equal to 40%. So 40% of the people in Jeremiah’s class are boys.
