Quote:Gialmere

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.

Correct!

A film about the life of Shakuntala Devi (aka The Human Computer) was scheduled for theater release this year but got covid canceled. It will instead start streaming on Amazon this Friday.

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)) )

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."Quote:GialmereQuote:gordonm888Very tricky wording. I would have first given the same answer as Joeman.

Correct!

Ambiguity in a contract benefits the party that did not draft it. I learned that watching The Big Bang Theory! ;)

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?

Quote:GialmereThe rectangle above is divided into 9 perfect squares.

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
