Adjacent angles in parallelograms are supplementary angles thus :
It has 4 extinct variables in the equation.
<span>Number of flowers = 6
Number of flowers to choose = 3
We need to solve it using permutations:
6!/3!=1*2*3*4*5*6/1*2*3 = 720/6 = 120
The answer is: there are 120 different arrangements using 3 types of flowers out of 6 types available</span>
I can do the first part, but the second part is confusing...

Find out how many plates Mike can pack in a minute.
60 (an hour) / .75 (3/4) = 45
180 / 45 = 4
Mike can pack 4 plates per minute.
Since Mike only packs 4 ppm, Lucy packs faster, with 5 plates per minute!
