125^-2/3= 1/125^2/3=1/(cube root(125))^2=1/5^2=1/25
Cross sectional area: half base x height = (6/2)h = 3h , Volume of prism: Cross sectional area x width, this gives: 3h10 = 120, rearrange: 3h = 12, Find h: h = 4cm.
3x(1-3x)
75% of 60: 0.7560 = 45 , 48% of 100: 0.488100 = 48 , His total marks: 45+48 = 93 , Total marks available: 100+60 = 160 , His final percen...
