A box is launched upward from the ground at a speed of 57 feet per second. Calculate the height in feet of the box at 3 seconds.
expeople1 [14]
The vertical height traveled is given by
h = ut +- (1/2)g*t^2
where 
u = 57 ft/s, initial speed
t = tme, s
g = 32 ft/s^2

After 3 seconds,
h = (57 ft/s)*(3 s) - (1/2)*(32 ft/s^2)*(3 s)^2
   = 171 - 144
   = 27 ft

Answer:  27 ft

147.1 is what percent of 155
Harrizon [31]
Solution for what is 147.1% of 155

155/x=100/147.1
(155/x)*x=(100/147.1)*x       - we multiply both sides of the equation by x
155=0.67980965329708*x       - we divide both sides of the equation by (0.67980965329708) to get x
155/0.67980965329708=x 
228.005=x 
x=228.005

now we have: 
147.1% of 155=228.005
