Jack bought a new set of golf clubs for $186.75. the original price was $249. what percent of the original price did he pay?

75% is the percent of which jack payed

Step-by-step explanation:

You can find this out by googling it, or even just using the elimination too. Right away 25% sounded way too low and if you look it up it says that its $68

instead of $186.75. And it can't be any higher than 100% because 186.75 is lower than 249, so that means that 75% is the only reasonable answer

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.
