Read Solution (Total 1)

18
(1*2*3*4*5*6*7*8*9*10*11*12*13*14*15)/34
to find out reminder we can write above problem as shown below
((1*2*9)/34)*((3*15)/34)*((4*14)/34)*((5*13)/34)*((6*12)/34)*((7*11)/34)*((8*10)/34)
=((18*11)/34)*((31*4)/34)*((12*9)/34)*(22/34)
=((28*6)/34)*((22*22)/34)
=(32*8)/34

find number of ways a batman can score a double century using 4's and 6's? My Dad has a miniature Pyramid of Egypt. It is 5 inches in height. Dad was invited to display it at an exhibition. Dad felt it was too small and decided to build a scaled-up model of the Pyramid out of material whose density is (1 / 9) times the density of the material used for the miniature. He did a "back-of-the-envelope" calculation to check whether the model would be big enough.

If the mass (or weight) of the miniature and the scaled-up model are to be the same, how many inches in height will be the scaled-up Pyramid? Give your answer to two places of decimal.
