Answer : 3, 360 ways
Total number of people running the race = 16
We have three slot to be filled for first, second and third
Any person can take the first position irrespective of the arrangement
one out of the 16 people can come first
out of the 15 people remaining , one person can also come second remaining 14
out of the 14 people, one person can also come third
The number of ways the gift can be awarded = 16 x 15 x 14
The nummber of ways the prizes can be awarded = 3360 ways
Let "x" be a substitute for "a number"
1/3(x)=x-12 Multiply by 3
x=3x-36 Get n onto the same side of the equation
2x=36 Divide by 2
x=18
That's your answer.
We have the formula of the volume: 480 = area rectangular base x 10 / 3 ;
Then, 480 x 3 = area reactangular base x 10;
Area rectangular base = 480 x 3 / 10;
10 x ( 9 x length ) = 480 x 3;
90 x width = 1440;
length = 1440/90;
length = 16 inches;
C. Side=11cm, side=5 cm, side=6cm
