Leni [432]
<h3>Answer: 985</h3>

=============================================

Work Shown:

A = amount after t hours

P = initial amount = 100

r = growth rate in decimal form = 0.10

t = number of hours = 24

--------

A = P*(1+r)^t

A = 100(1+0.10)^24

A = 100*(1.10)^24

A = 100*9.84973267580762

A = 984.973267580762

A = 985

A rectangular
igor_vitrenko [27]
A = length x width

15,000 = (w + 30) x w
15,000 = w^{2} + 30w
0 = w^{2} + 30w - 15,000

Use quadratic formula to find that  w= -15 + or - 5\sqrt{609}. Because distance cannot be negative, the width is -15 + 5\sqrt{609}meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
