Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
All Four quadrants. It is basically a ramp that goes up through all four of them.
To make it easier, I am going to simplify it.
4×16-16 ? 4×[24-2×(4+8)]
64-16 ? 4×[24-2×12]
48 ? 4×[24-24]
48 ? 4×[0]
48 ? 4×0
48 ? 0
48>0
The symbol is >, so the answer is A.
The volume of a cylinder with a radius r and a height h:
The volume of a cone with a radius r and a height h:
Therefore
We have 
Substitute:
Answer: The volume of a cone is equal 10.75 in³
Answer:
10.
here,
h=c
b=5
p=12
,we know that,
h²=b²+p²(pythagoras theorum )
c=5²+12²
c=25+144
c=169
hence the value of c is 169.
