Answer: the mass of a neutron is approximately 2,000 times the mass of an electron
Step-by-step explanation:
- the easiest way to solve this (in my opinion) is to simply divide the mass of a neutron by the mass of an electron
- ![2 x10^{-24} / (9 x10^{-28} )](https://tex.z-dn.net/?f=2%20x10%5E%7B-24%7D%20%2F%20%289%20x10%5E%7B-28%7D%20%29)
= ![(2/9) x10^{-24--28}](https://tex.z-dn.net/?f=%282%2F9%29%20x10%5E%7B-24--28%7D)
= ![(2/9)x10^{-24+28}](https://tex.z-dn.net/?f=%282%2F9%29x10%5E%7B-24%2B28%7D)
≈ ![0.2222x10^{28-24}](https://tex.z-dn.net/?f=0.2222x10%5E%7B28-24%7D)
≈ ![0.2222x10^{4}](https://tex.z-dn.net/?f=0.2222x10%5E%7B4%7D)
≈ which is approximately 2222
- so 2222 is approximately 2000 times
- therefore, the mass of a neutron is approximately 2,000 times the mass of an electron
hope this helps :)
Answer:
Hello! :) I hope I’m correct!!
Step-by-step explanation:
I think the answer should be 395.20
Price= 380.00
Sales tax= 4% (15.20)
The total price will be 395.20
If SP = Rs 380 and sales tax is 4% then the amount of sales tax is 395.20
Therefore the answer will be 395.20
Hope this helps!

Sample Response:
<em>The linear equations have the same slope, so the rate of change for each is the same. As long as the rate of change is the same, the lines will stay the same distance apart and not intersect.</em>

Answer:
10
Step-by-step explanation:
A bakery makes 40 different flavors of muffins.
25% of the flavors have chocolate as one of the ingredients.
Convert 25% to fraction:
![25\%=\dfrac{25}{100}=\dfrac{1}{4}](https://tex.z-dn.net/?f=25%5C%25%3D%5Cdfrac%7B25%7D%7B100%7D%3D%5Cdfrac%7B1%7D%7B4%7D)
So, there are
![40\cdot \dfrac{1}{4}=10](https://tex.z-dn.net/?f=40%5Ccdot%20%5Cdfrac%7B1%7D%7B4%7D%3D10)
muffins which have chocolate as one of the ingredients.
In attached tape diagram:
green - with chocolate
blue - without chocolate
