3
3/5 x 3 = 9/5
9/5 = 1 4/5
Number 5 is c, number 6 is 'a'
first step is to subtract 21 from both sides
2m+21-21=3-21
2m=-18
2m/2 and -18/2
m=-9
So the final answer is m=-9 (negative nine equals m)
J=1
explaination:
2 is greater than or equal to 3
4 - j(1)= 3
V=1024 pi m^3 and v=250 pi m^3
the similarity ratio of the smaller to larger similar cones is
k= V/v=1024 pi m^3/250 pi m^3= 4.096
the great cone is 4.096 times of the small cone (in volume)
