If Stacy Tanner, Capital has instead decreased $30,000 after the closing entries were posted, and the withdrawals remained the same, what would have been the amount of net income or net loss?

$60,000 ( 50% loss)

Step-by-step explanation:

If Stacy Tanner had a capital decrease of $30,000 and still having $30,000 after closing entries, this explains that $60,000 would have remained after closing entries.

If $60,000 would have remained, it means that, as calculated below:

If 100% where to be generated as capital = $60,000

then % loss, that is, $30,000 = 100 X 30,000/60,000 = 50%

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

it's is b
