Fifty minutes ago if it was four times as many minutes past three o'clock, how many minutes is it to six o'clock?



Very tricky wording. I would have first given the same answer as Joeman.

26 minutes to 6:00 or 5:34

50 minutes ago it was 4:44, which is 104 minutes past 3:00. 104 minutes is 4*26.

A drunk takes a step south with probability p (where 0<p<0.5) and otherwise takes a step north. What is the probability he ever returns to the point he started?

I am not entirely sure why, but I get 2p

The value is 2 times the sum of (p (1-p) + the sum over all positive integers n of ( (p (1-p))^(n+1) x (Combin(2n, n) - Combin(2n, n-1)) )

Correct!

The way the question is written, I still stand by my answer. To get her answer, the question would have been better written as: "How many minutes is it to six o'clock? Fifty minutes ago if it was four times as many minutes past three o'clock."

The rectangle above is divided into 9 perfect squares.

The smallest square (colored black) has a side length of 4cm.

What is the area of the rectangle?

What is the area of the rectangle?



Label the eight squares as follows:
A - upper left
B - upper right
C - left edge, below A
D - touching A, B, C
E - below D
F - bottom left
G - bottom center
H - bottom right

G = E + 4
F = G + 4 = E + 8
C = F + 4 = E + 12
C + 4 = D + E -> E + 16 = D + E -> D = 16

A = C + D = E + 12 + 16 = E + 28

B = A + D = E + 44

B + D = E + H -> E + 44 + 16 = E + H -> H = 60

H = E + G = 2E + 4 -> E = 28

The eight squares A, B, C, D, E, F, G, H have side lengths 56, 72, 40, 16, 28, 36, 32, and 60, respectively

The width of the rectangle = A + B = 128
Check: it is also F + G + H = 128
The height of the rectangle = A + C + F = 132
Check: it is also B + H = 132
The area = 128 x 132 = 16,896
