so 2^3 is 8
Answer:
46.86
Step-by-step explanation:
a^2+b^2=c^2
30^2+36^2=c^2
2196=c^2
Square root both sides
46.86=c
Answer:
Check the explanation
Step-by-step explanation:
Since each and every one of the 4 hallways is equally likely then

Now, if he chooses H1 he escapes after 12 minutes then

If he chooses H2 then he wastes 10 minutes and then he is again in the same starting
position so he expects to escape in E(T) minutes, then

Analogously, if he chooses H3 then he wastes 40 minutes and then he is again in the same starting
position so he expects to escape in E(T) minutes, then

Therefore

So we have

Therefore he is expected to escape in 72 minutes
Answer:
K = 10
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin K = 11 / 61
Taking the inverse sin of each side
sin ^-1 ( sin K) = sin ^-1 (11/61)
K =10.38885782
K = 10
