I got 2 but this could be wrong. Hope this helps ;D
Knowing the squareroot of 81 is 9, we can easily know that square root of 83 is close to 9.
9 to the closest tenth is 10.
Hope I helped :)
Step-by-step explanation:
Because vertical angles have equal measure, angle CPB = 90 degrees. By extension, angle CPQ + angle QPB = 90 degrees
So 2x+4x+12=90
6x+12=90
6x=78
x=13
Follow the order of operation (PEMDAS) giving you 31
By buying 2 tickets you doubled the probability of you winning something. So, the probability that one of your tickets will win something is 0.08. Hope this helps :)
