Becasue different trees have different adaptations and serve as food for animals that live in that ceratin place.
X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
Answer:
probability is 50 percent
Step-by-step explanation:
total area= 30000
area of secknd ring=15000
therefore 15000/30000 times 100
equals 50 percent
the answer is 60
Step-by-step explanation:
the answer is 60 because you just divide30/,5
Here it is given that the triangles ABP and DCR are similars, therefore we use the ratio rule which states that
corresponding sides of similar triangles are in same proprtion .

that gives
7/10 = BP/11
7*11=10BP
BP=7.7
Again using the ratio rule

7/10 = AP/6
42 = 10AP
AP = 4.2
Perimeter= AB+BP+AP = 7+7.7+4.2 = 18.9
Correct option is A.
