Answer:
Percentage loss of the number of trees is
.
Step-by-step explanation:
Given: After a storm,
trees out of
were left standing.
To find: What is the percentage loss of the number of trees?
Solution:
We have,
Total number of trees 
Number of trees left standing 
Therefore, loss of trees
We now that

.
Answer:
9+6i
Step-by-step explanation:
3+6=9
5+1=6
C=pi(d)
So d=7ft
Then pi(7ft)=21.98
The question requires that the four lines that intersect form a parallelogram but not an specific parallelogram, so you are not restricted by a diagram.
You can use these equations for the four lines:
1) y = 0 (it is the x-axis)
2) y = 4 (it is a line parallel to the x-axis, whose y-intercept is 4.
3) y = x (it is an inclined line that intersects both y = 0 and y = 4 lines.
4) y = x + 7 (it is a line parallel to y = x, that also intersect the both y = 0 and y = 4 lines.
