Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
Let n = 30
We are actually looking for a_30.
a_30 = 4(30) + 1
a_30 = 120 + 1
a_30 = 121
Answer:
Answer is 1/13
Step-by-step explanation:
Here we are not intimated about the first (01) twelve (12) cards that are shown, the probability that the thirteenth (13) card dealt is a King, if this is the same as the probability that the (01) first card shown, or in fact any particular card dealt is a King, then it equals:
=4/52
=1/13 ANS
5x + 7
5x represents the weight of the 5 striped fish.
7 represents the fish that weighs 7 pounds.
Let n be one side of the square wood block. Then:
n²=872
n=√872=approx. 30" per side
