We can tell it’s not a permutation because it’s picking two people. Order doesn’t matter.
The number of total possible groups of men is 9 C 2 = 9!/((9-2)!(2!)) = 36
The number of total possible groups of women is 11 C 2 = 11!/((11-2)!(2!)) = 55
55 * 36 = 1980 different groups in the committee
180 - 72 = 118
And then the other way around is
72° again, makes the answer 118°.
Parallelogram as well as a quadrilateral with pairs of equal and parallel opposite sides
Sorry, i think you forgot to place the second function. please do so!
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
