An egg is dropped from a height of 90 ft. if acceleration due to gravity is _16 ft/s2 and initial velocity is 0 ft/s, approximately how long will it take for the egg to reach the ground?

The answer is B
The acceleration due to gravity or "g" value on earth's surface is : -32 ft/sec² where positive values are upwards. 
V= initial velocity = 0   because it is dropped from 90 ft in height 
H= height = 90 ft 
     h{t} = (½) • g • t²+ (Vyi) • t + Hi actual equation 
     h{t} = (½) • (-32) • t² + (0) • t + 90 
     h{t} =(-16) • t²+90 : which is the equation 
        0= (-16) • t²+ 90 : the height at ground level is zero. 
           t =2.37 sec is the time of flight so the choice: b

Make them both to where they have the denominator of 18that makes 3/2 equal 27/18 and 1/9 equal 2/18so now you have  27/18x+5=2/18subtract 5 from the other sideso now you have 27/18x+2/18-5then subtract 2/18 from 27/18 to get 25/18x=-5then divide 25/18 by -5 and your answer will be  -5/18

Iwould say earthquakes.
