The boundaries are, in this question, the corner points.
(0,0) given
(0,6) => 3(0)+5(6) = 30
(5,3) => 5+3 = 8
(8,0) => 8+0 = 8
So all these points satisfy all inequalities.

1st and 2nd.

1st one. Take the very bottom  vertice up to the top so its above the top two, then if you redraw the edge from the top right to the bottom left it becomes planar.
2nd one. Swap the bottom left vertice with the place of the bottom right, and redraw the edge between them so it goes around the other vertices, and it becomes planar.

All but 9 is correct. For question 9 you didn't calculate the interest that would also have to be payed on the $802.39. The answer should be E.

[NamasteLjubo]

Did anyone else get E for question 9 in Business?

How did you get A?

Its a scale factor question.
The area ratio is 15:9 (simplified), multiply that by 180 to get the area of the new cone, that includes the middle and top sections. This gives you 500, then subtract the area of the top cone, which was 180, to give an answer of 320.

Yep... Can't believe I let that slip. 1 Mark dropped then. Damn

[soysauce]

How did you get A?

(I may be wrong here...)
two heights = 6 and 9
9/6 = 1.5 = k
k^2 (because area) = 2.25
2.25x = 180
x = 80
