Answer to Question #160847 in Algebra for joseph rowland

Question

If your front lawn is 16.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1050 new snowflakes every minute, how much snow, in kilograms, accumulates on your lawn per hour? Assume an average snowflake has a mass of 1.80 mg.

Answer 1

$$Area=16ft\times 20ft=320ft^2$$

The number of accumulated snowflakes per hour

$$1050\times320\times60=20160000$$

How much snow, in kilograms, accumulates on your lawn per hour

$$20160000\times 1.80\times10^{-6}kg=36.288\ kg$$
