Julie is doing an experiment. she is studying a cell that triples every hour. she started the experiment with 24 cells. how many cells are there at the end of 4 hours?

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

6 cars because if you have 8 and subtract 2 youll have 6 left over
