Answer:
After 15 years, the area will be of 775.3 km²
Step-by-step explanation:
The equation for the area of the forest after t years has the following format.

In which A(0) is the initial area and r is the yearly decrease rate.
A certain forest covers an area of 2600 km2.
This means that 
Suppose that each year this area decreases by 7.75%.
This means that 
So


What will the area be like after 15 years?
This is 


After 15 years, the area will be of 775.3 km²
Answer:
4.8m
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.
Answer:
p = -3
Step-by-step explanation:
Apply algebra to the equation by subtracting 4 from each side, that way it will cancel out at least the 4 next to p. It should now look like this: p = -3
Because we can't make anymore moves and the expression clearly states what p is, we're done!
