A) 42,000m divided by 2 1/3 = 18,000m divide by 1000m to get km = 18km/hr
B) 18,000m divided by 60 to get minutes = 300m divide by 60 to get seconds = 5m/sec.
Conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse. The circle is a special case of the ellipse, previously called the fourth type. Planes that pass through the vertex of the cone will intersect the cone in a point, a line or a pair of intersecting lines, called degenerate conics.
( 4 / 5 )^-2 = ( 5 / 4 )^2 = 25 / 16 ;
Well, 9 is the largest, but 4 is the smallest and 3 is the second odd number.
So it would go yes, no, no or if it's just one question, it would be no.
