Explanation: I'm honestly too lazy to do the math for the rest but the conversions can be done simply by using a ratio like ½ = ⅓ and you cross multiply (you'll probably have one side with a variable, just divide both sides by the number multiplied to the variable if necessary).
Answer:
To equal the height of the Gateway Arch in St. Louis, it would take <u>76810 half dollars.
</u>
Explanation:
If the Gateway Arch in St. Louis is 630 feet high, how many half dollars will it take to equal the height if each half dollar is 2.15mm thick?
First, we convert the ft to cm and the cm to mm.
- 1 ft = 30.48 cm
630 ft = 19202.4 cm
- 19202.4 cm = 192024 mm
Now, if a half dollar is 2.15 mm thick, how many half dollars would it take to equal the height of 192024 mm?
1 half dollar = 2.15 mm
X = 192024 mm
X = 192024 mm / 2.15 mm
X = 76810 half dollars.
