Its way easy
Quote:
1 min = 60 sec 30 sec X 20 = 600 sec 600 sec = 600/60 = 10 min Commercials time in minutes = 10 Commercial time as fraction of hour= 10/60 or 1/6 = 0.1666 Commercial time as percentage = 0.1666 X 100 = 16.67% Commercial time to nearest percent = 17% Hope this helps

Please solve this one, its answer is 64, but when I am doing it, I get 118
if x=1, y=3, z=4 then evaluate x^2+y^2+z^2-3yz^2 |
