Miss garcia is ordering pizza for students in the homework club. a large two-topping pizza is 20% off the regular price of $15. miss garcia wants to know the sale price. what percent of the regular price is the sale price.

Sale price is $12 which is 80% of the regular price.

Step-by-step explanation:

A large two-topping Pizza is 20% off the regular price of $15.

Therefore, the sale price is dollars. (Answer)

Now, let us assume that x% of regular price i.e. $15 is the sale price i.e. $12.

So,

⇒

⇒ x = 80%  (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.
