Answer:
33
Step-by-step explanation:
(0.5, 1.3) is the correct answer
Step-by-step explanation:
Given equations are:
![y = 4x-0.8\ \ \ Eqn1\\2x+y-2.3=0\ \ \ Eqn2](https://tex.z-dn.net/?f=y%20%3D%204x-0.8%5C%20%5C%20%5C%20Eqn1%5C%5C2x%2By-2.3%3D0%5C%20%5C%20%5C%20Eqn2)
As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.
We can plot the graph of both equations using any online or desktop graphing tool.
We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)
We can see from the graph that the lines intersect at: (0.517, 1.267)
Rounding off both coordinates of point of intersection to nearest tenth we get
(0.5, 1.3)
Hence,
(0.5, 1.3) is the correct answer

Answer:
The answer is "The second choice".
Step-by-step explanation:
![r=6\\\\h=13 \\\\](https://tex.z-dn.net/?f=r%3D6%5C%5C%5C%5Ch%3D13%20%5C%5C%5C%5C)
Formula:
![A=2\pi rh](https://tex.z-dn.net/?f=A%3D2%5Cpi%20rh)
![=2\times 3.14 \times 6 \times 13\\\\=2\times 3.14 \times 78\\\\=3.14 \times 156\\\\=3.14 \times 156\\\\=489.84 \approx 489.8 ft^2](https://tex.z-dn.net/?f=%3D2%5Ctimes%203.14%20%5Ctimes%206%20%5Ctimes%2013%5C%5C%5C%5C%3D2%5Ctimes%203.14%20%5Ctimes%2078%5C%5C%5C%5C%3D3.14%20%5Ctimes%20156%5C%5C%5C%5C%3D3.14%20%5Ctimes%20156%5C%5C%5C%5C%3D489.84%20%5Capprox%20489.8%20ft%5E2)
