Answer:
The 40 ounce jar is cheaper
Step-by-step explanation:
how i did this was divide 6.00 by 30 to get 0.2 cents per ounce then 7.20 divided by 40 to get 0.18 cents per ounce so the 40 ounce jar would be cheaper, hope this helps.
2 lines are skew if they are neither parallel, nor intersecting.
If 2 lines are parallel or intersecting, they form a plane, so they are coplanar. So "skew" is the opposite or complement of "coplanar".
i) a and b: are both on M so coplanar, not skew
ii) b is in M, c is in N and they have no common point, so skew. (if they had a common point that would be a point in the line d of intersections of planes M and N, but they dont meet at such a point)
iii) b and e: are both on M so coplanar, not skew
iv) e and c : skew, same argument as ii.
v) a and e : are both on M so coplanar, not skew
vi) a and c: a is in M, c is in N. If they met, they would met at a point on line d, the only set of points common to planes M and N, but they dont. so skew
