Answer:
The area after 9 years will be 1,234 km^2
Step-by-step explanation:
In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.
To answer this question, we shall be using an exponential approximation.
Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.
This can be written as;
A = I(1-r)^t
where A is the new area we are looking for
I is the initial area which is 1700 according to the question
r is the rate of decrease which is 3.5% = 3.5/100 = 0.035
t is time which is 9 years according to the question
We plug these values and have the following;
A = 1700(1-0.035)^9
A = 1700(0.965)^9
A = 1,233.66
This is 1,234 km^2 to the nearest square kilometer
Answer:
11
Step-by-step explanation:
2(l+w)
40= 2(9+x)
40= 18+2x
Subtract 18 from 40
22=2x
Divide 2x by itself and 22
11=x or x=11
When you triple the height of the box, it can hold (900 x 3) = 2,700 pieces.
Then triple its length, and it can hold (2,700 x 3) = 8,100 pieces.
Then triple its width, and it can hold (8,100 x 3) = 24,300 pieces.
When you triple the dimensions of a 3D object, it has 27 times its original volume. (900 x 27) = 24,300 .
