A.
y = 20(1.15)^x.....parrots
y = 4x + 24.....snakes
B. after 10 yrs
y = 20(1.15^10)
y = 20(4.05)
y = 81 parrots
y = 4(10) + 24
y = 40 + 24
y = 64 snakes
C.
20(1.15)^x = 4x + 24
x = 6.63 years they will be the same
(1/3+1/2)-(5/6-3/4)=
1/3+1/2-5/6+3/4=
4/12+6/12-10/12+9/12=
10/12-1/12=
9/12=
3/4

Answer:b
Step-by-step explanation:
Answer:
The length of XY is either 10 or 2.5.
Step-by-step explanation:
Given information: ZY = 5, XC = 3 and DC = 4.
Case 1: Rectangle ABCD is smaller than ZBXY.
The opposite sides of the rectangle are same.



The length of ABCD is 4 and width of ABCD is 2. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.



Therefore the value of XY is 10.
Case 2: Rectangle ABCD is larger than ZBXY.



The length of ABCD is 4 and width of ABCD is 8. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.



Therefore the value of XY is 2.5.
