Circumference = 2 pi r = 10
r = 10 / 2 pi
75% of the error = 0.75 * pi * (10 / 2pi)^2

The solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)
<h3>How to determine the solution to the
system of equations?</h3>
The system of equations is given as:
x^2y + yx^2 = 20
1/x + 1/y = 5/4
Multiply through the equation 1/x + 1/y = 5/4 by 4xy
So, we have:
4x + 4y = 5xy
So, we have the following system of equations
4x + 4y = 5xy
x^2y + yx^2 = 20
Next, we plot the graph of the system of equations
4x + 4y = 5xy
x^2y + yx^2 = 20
See attachment for the graph of the system
From the attached system, we have the point of intersection to be
(x, y) = (-3.88, 0.66) and (3.04, 1.09)
Hence, the solution to the system of equations is (-3.88, 0.66) and (3.04, 1.09)

Answer: 80
Step-by-step explanation: If he is 20% complete, then 20 x 5 is 100. So if we want to get 100%, then we have the multiply. Now he did 16 questions, so we have to multiply 16 five times. 16 x 5
