Well if you know what the area of the rectangle is and the width then you would have to divide area of the rectangle by the width.
24,396 / 38 = 642
The length is 642 centimeters.
Hope this helps!
= 120/100 x 320
= 12 x 32
= 384
Answer:
On the way up, 1.8 seconds and on the way down 4.1 seconds.
Step-by-step explanation:
Use the motion under gravity equation s = ut + 0.5gt^2 where u = initial velocity, s = the height, t = time and g = acceleration due to gravity ( 32 fts-2).
So 120 = 95t + 0.5(-32)t^2
-16t^2 + 95t - 120 = 0
Solving this using the quadratic formula:
t = [-95 +/- √(95^2 - 4 * -16*-120)] / -32
t = 1.823, 4.1148.
The first value refers to the upward journey and the second to the downward journey.
