Answer:
3/5 of a serving. Or 6/10. Since he doesn't have a whole serving.
Sn=n/2 (2a1 +(n-1)d)
[s5= 5/2 (2a1 +(5-1)d) = 5a1+10d]
s6=3(2a1+5d) = 6a1+15d
s4=2(2a1+3d) = 4a1+6d
6a1+15d -(4a1+6d) = 5 -----(1)
s7=7/2(2a1+6d) =7a1+21d
6a1+15d + 7a1+21d = 21 -----(2)
(1) 2a1+9d=5 -----(3)
(2) 13a1+36d=21 ----(4)
(3)*4 ; 8a1+36d=20 ----(5)
(4)-(5) 5a1 = 1
so a1 = 1/5
(3) 2a1+9d=5
2(1/5)+9d = 5
9d = 5-2/5 =23/5
d = 23/45
so [s5= 5/2 (2a1 +(5-1)d) = 5a1+10d = 5(1/5) + 10(23/45) = 1 + 5.11 = 6.11 ]
i'm not sure about the answer but the process is correct
Answer:
The chicken coops needs to be atleast 25 feet in width.
Step-by-step explanation:
The chicken coop is in a shape of a rectangle.
Area of rectangle is given by length * width
Since, length is given as 12 ft and area is given as minimum 300 ft, the width can be found by substituting these values into the area formula:

The chicken coops needs to be atleast 25 feet in width.
