Water goes over niagra falls at a rate of 180 million cubic feet every 1/2 hour. how much water goes over the falls in 1 minute?

6 million cubic feet

Step-by-step explanation:

180--> 30min(1/2hour)

Divide by 30 to get 1 minute.

180/30 million cubic feet= 6 million cubic feet

18

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.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
