Every year, roughly 25,000,000 kg of hair is cut in the united states. each kilogram of hair contains about 0.0002 kg of zinc, and each kilogram of zinc is worth about 4 dollars. how many dollars worth of zinc is contained in hair cut in the united states every year?

$20,000

25,000,000 x 0.0002 = 5,000

5,000 x $4.00= $20,000

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
