(4/9)/16 = 4/(9*16) = 4/(4*4*9) = 1/(4*9) = 1/36

Circular pen means you are going to use Area = Pi(r^2).
So 78.5 = pi(r^2). Divide by pi on both sides to get r^2 = 78.5/pi. Take the square root of that to get r or radius = approximately 4.99. If you need an exact answer then use

for the next part because you are not done yet.
Plug whatever R you use into the circumference formula of Circumference = 2(pi)(r).
If you use 4.99, you do 2(pi)(4.99) which is approximately 31.35. If you use the exact answer, you do 2(pi)(

) which gives you approximately 31.41.
Either way you'll need about 31 meters of chicken wire but the 31.40796 or ~31.41 is closer to the exact answer.
The difference between the maximum value of g(x) and the minimum value of f(x) is 5.
Given function is:
......(1)
<h3>What is the general form of a quadratic equation?</h3>
The general form of a quadratic equation is
with
.
As we know the minimum value of a quadratic function is
when a>0
For f(x) a>0 so minimum value of f(x) =
=7
From the graph, the maximum value of g(x) =12
So, the difference between the maximum value of g(x) and the minimum value of f(x) =12-7 =5
Hence, the difference between the maximum value of g(x) and the minimum value of f(x) is 5.

Answer: 
Step-by-step explanation:
Given
The ratio of mixture of sand and cement is 5:3
If the total volume of mixture is 
Suppose there is 5x and 3x cubic centimeter of sand and cement respectively i.e.

Sand 
So, there is
of sand in the mixture
5X-20=4X+7
5X-4x=20+7
X=27°
