Can someone me here is my question i also attached the circle graph

people leaving a movie theater were asked to name their favorite type of movie. the circle graph shows the percent of people surveyed who preferred each type of movie.

of the people surveyed, 27 said that science fiction is their favorite type.

how many people were surveyed in all?

enter your answer in the box.

The answer is 150 people

Step-by-step explanation:

First, if you take the 27 and the 18%, the both go into 3. If you reduce, you will get 3:2. then you can multiply them by 5 to get 15 people for 10%. Multiply them by ten to get 100% and you will get 150 people because 15 times 10 = 150.

                                                 Hope this helps!

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.
