Final answer:
To calculate the additional thickness of a nickel compared to a penny, divide the heights of their respective stacks by 12 and subtract the averages, resulting in a 0.435 mm difference. However, this result does not match any of the answer choices provided, suggesting a possible typo or inconsistency in the question.
Step-by-step explanation:
The height of a stack of 12 pennies is 18.24 millimeters, while the height of a stack of 12 nickels is 23.46 millimeters. To find out how much thicker one nickel is than one penny, we need to calculate the average thickness of a single penny and a single nickel and then find the difference.
First, divide the total height of the penny stack by the number of pennies:
- Height of penny stack / Number of pennies = Average thickness of one penny
- 18.24 mm / 12 = 1.52 mm
Now, do the same for the nickels:
- Height of nickel stack / Number of nickels = Average thickness of one nickel
- 23.46 mm / 12 = 1.955 mm
Finally, subtract the average thickness of a penny from that of a nickel to find the additional thickness:
- Average thickness of one nickel - Average thickness of one penny = Additional thickness of a nickel
- 1.955 mm - 1.52 mm = 0.435 mm
If we combine this calculation with the question options, it seems like there might be a typo since none of the listed answers match our result of 0.435 mm. Therefore, based on the presented calculations, the thickness difference would actually be 0.435 mm.
