Answer:
t= 12.9 years
Step-by-step explanation:
Value after t years = initial value ( 1 - r )^t
Where,
Value after t years= $5000
Initial value = $22,400
r= depreciation rate = 11%
t= length of time (years)
Value after t years = initial value ( 1 - r )^t
5000 = 22,400 ( 1 - 0.11)^t
5000 = 22,400(0.89)^t
Divide both sides by 22,400
(0.89)^t = 5000 / 22,400
(0.89)^t = 0.2232
Take the log of both sides
t log 0.89 = log 0.2232
t= log 0.2232 / log 0.89
= -0.6513 / -0.0506
= 12.87
t= 12.9 years

Answer:
<h2>The area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.</h2>
Step-by-step explanation:
Assuming that the parallelogram is a rectangle, its perimeter would be defined as
Where
is the width and
is the length.
But,
, so

Which means the sum of its dimensions is 40 meters.
Easily, its dimenions can be 10 meters and 30 meters.
So, its area would be

Therefore, the area of the parallelogram is 300 square meters. Its height (length) is 30 meters and its width is 10 meters.
30 onions in each row because 600/20 is 30.
