52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards
probability of getting 1 heart at first is 1/4
one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51
multiply
1/4 times 12/51=3/51=1/17
72 pints converted into gallons are 9 liquid gallons
Ok
in a 30-60-90 right triangle, if the leg oposite the 30 degree angle is x then the hypontuse is 2x
if the leg oposite the 30 degree angle is 12 inches then the hypontuse is 12*2 or 24 inches
