y = k/x
5 = k/(1) k = 5
y = 5/x
y = 5/15 = 1/3
1/30 + 1/x = 1/12
solve for 'x'
.05 x + .1 (9) = .06 ( 9+x) solve for 'x'
When I draw Venn I come up with 238 must play two sports ....
11 c 4 =330
12 c 4 = 495
Each hour represents 360o /12 = 30 degrees from the 12 (straight up position) 5 hours would be 150 degrees
1/2 = e-k(73.83)
k=.009388422
.1 = e-.009388422 t
t= ~ 245 days

To have no real solutions , the discrimintant of the quadratic equation must be <0
m^2 - 4ac < 0
m^2 - 160 < 0
m^2 < 160
m < 12.64 so 12
Maximum will be when all sides are equal (making it a square)
6 x 6 = 36 in2
