Let W and L be width and length of the rectangular pen respectively.
Therefore,
Circumference, C = 2W+2L= 130 yd
Area, A = LW = 1050 yd^2=> L = 1050/W
Using the circumference expression and substituting for L;
130 = 2W + 2(1050/W) = 2W+2100/W
130*W = 2W*W + 2100
130W = 2W^2 +2100
2W^2-130W+2100 = 0
Solving for W;
W= [-(-130)+/- Sqrt ((-130)^2-4(2)(2100)]/2*2 = 32.5+/- 2.5
W = 30 or 35 yd
When W = 30, L = 1050/30 = 35
When W = 35, L = 1050/35 = 30
Therefore, W = 30 yd and L = 35 yd.
Answer:
942
Step-by-step explanation:
If 5 is the radius and 12 is the height, and the formula of a cylinder is V=πr^2h, we can substitute.
V=π(5)^2(12)
5^2 is 25, and 25 times 12 is 300.
300π, and that would be approximately 942.

Answer:
0 = 0
Step-by-step explanation:
The input is an identity: it is true for all values.
Answer:
y=9x+0
Step-by-step explanation:
So if you look at the table, <em>y </em>is multiples of 9.
To solve this just put a 1 over the 15. So it would be 12/7 + 15/1 which is 16 5/7.
