The most common railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet tall. What is the volume, in cubic feet, of common railroad boxcars?

the answer should be a. snail

no

explanation:

you can be freinds, and people but not follow people.

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
