They are parallel because they have the same slope
To be apart of that state for atleast ten years is one.
So one coat uses 125 chinchillas . So, 10 * 125 will give you how many will give you 1250 chinchillas.. this is the number of chinchillas needed for 10 coats. So for 2 years you would have to multiply it by two so, 1250 * 2 = 2500.
The answer is 0.12 millimeters because if you multiplied the numbers it would give you 0.12 mm hope this is correct
