The amount of gold coating in millimeters needed for the ring is the difference between the total coating and the coating that has already been applied. From the given above, that would be,
                                    0.03 mm - 0.021 mm = 0.009 mm
Thus, the answer to this question is letter B.

kotegsom [21]

Answer:

18

Step-by-step explanation:

6 2 1    How many ways does this produce and are they legitimate?

  • 6 2 1
  • 6 1 2
  • 2 6 1
  • 2 1 6
  • 1 2 6
  • 1 6 2  

So any combination that you come up with, will produce 6 variations within those three choices. They are legitimate.

Lets see what you get with at most 5 estates to one person

5 3 1    Which will also give 6 variations. There are no other ways to make 5

4 3 2   Which will give 6 variations

I don't think there are any more possible choices.

  • 621
  • 531
  • 432

Are the only 3 ways the estates can be split given the rules. Each choice leads to 6 other choices. The total is 18
