Abridge hand is made up of 13 cards from a deck of 52. find the probability that a hand chosen at random contains at least 1 ten

5,600 x 10^3 = a) 560 b) 5,000,600 c) 5,600,000 d) 56,000

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
