Answer: The wavelength of red light is 2 times longer than the wavelength of violet light.
Step-by-step explanation:
Let be "x" the number of times the wavelength of red ligth is longer than the wavelength of violet light.
Knowing that the wavelength (measured in meters) of red light is about
and the wavelength (measured in meters) of violet light is
, you have to:
Divide the wavelength of red light (measured in meters) by the wavelength of violet light (measured in meters).
Then:
![x=\frac{wavelength\ of\ red\ light}{wavelength\ of\ violet\ light}\\\\x=\frac{8*10^{-7}}{4*10^{-7}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bwavelength%5C%20of%5C%20red%5C%20light%7D%7Bwavelength%5C%20of%5C%20violet%5C%20light%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B8%2A10%5E%7B-7%7D%7D%7B4%2A10%5E%7B-7%7D%7D)
Remember the Quotiend of powers property:
![\frac{b^m}{b^n}=b^{(m-n)}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%5Em%7D%7Bb%5En%7D%3Db%5E%7B%28m-n%29%7D)
Then:
The wavelength of red light is 2 times longer than the wavelength of violet light.
Answer:
Not enough information, Im sorry.
Step-by-step explanation:
Originally without the 10% extra, both have 100%. since the question stated that the first salesperson have 10% more, the percentage of his paycheck will be a total of 110%. on the other hand, the second salesperson will have only 100%. the question then stated that when both oaychecks are added together, it will give a total of $1075.
110% + 100% represents $1075
210% represents $1075
so now you need to find what is 1 %
1% represents $(1075/210)
the first salesperson have 110%, so you
(1075/210) × 110% = $563. 0952381
round off to the nearest cent so it will become $563.10
the first salesperson paycheck is $563.10
the second salesperson paycheck 100%. so you....
(1075/210) × 100% = $511.9047619
=$511.90
therefore the second salesperson paycheck is $511.90.
If your only solving for the perimeter, then the answer is 18yd.
