Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
First step is to calculate x return on investment
x return on investment = $600 - $500
x return on investment= $100
Second step is to calculate y return on investment
y return on investment= $900 - $750
y return on investment= $150
Now let determine the ratio of return on investment from company x to that from company y
Using this formula
Ratio of return on investment=x return on investment/y return on investment
Let plug in the formula
Ratio of return on investment=100/150
Ratio of return on investment=2/3
Ratio of return on investment=2:3
Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

I don’t know
Wow,that’s a tough one
Answer:
Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.
Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?
amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms
amount of moles of silver= 2.98×10⁻⁴ moles
Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
