Step-by-step explanation:

$\left(6x+4\right)+10x=180$

The volume of a sphere is 5000 pi m 3 what is the surface area

Nikitich [7]

$V = \frac{4}{3}\pi r^3
\\ 5000\pi = \frac{4}{3} \pi r^3
\\ 5000 = \frac{4}{3} r^3
\\ \frac{3}{4} * 5000 = r^3
\\ 3750 = r^3
\\ r = 15.536
\\ SA = 4 \pi r^2
\\ SA = 4\pi (15.536)^2
\\ SA = 3033.11$

Who wants to help me on question 41. I don't understand what it means when it says "label a net".

Novosadov [1.4K]

A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.

Answer: Delete the point (0, 4)

Step-by-step explanation:

Your line for y = (1/3)x + 4 is correct.

m=1/3 b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.
