Parker bought a student discount card for the movies. The card cost $7 and and allows him to buy movie tickets for $5.50. After one month, Parker has spent $89.50 total. How many tickets has he bought since getting the discount card?

OpenStudy (sleepyjess):

89.50 (amount spent on tickets)/5.50 (amount per ticket) = number of tickets

do you know how to do this one too Four rectangles are shown in the diagram. For which dilation is the ratio of the side lengths 1:2?

OpenStudy (sleepyjess):

What do you think the answer is?

OpenStudy (anonymous):

im not sure how to do it

OpenStudy (sleepyjess):

it is asking which rectangle has 1 unit up or across for every 2 on another rectangle so really you are just looking for which rectangle has sides that are double another rectangles

OpenStudy (sleepyjess):

so pick 2 rectangles and we will figure out the dilation ratio

OpenStudy (anonymous):

d c and ba

OpenStudy (sleepyjess):

ok so the side length of D is 2 and the side length of C is 4 is that a 1:2 ratio?

OpenStudy (anonymous):

yea

OpenStudy (sleepyjess):

what ratio is B:A?

OpenStudy (anonymous):

op sorry i mean 6:8

OpenStudy (sleepyjess):

correct and that simplifies to 3:4 if you want to you can do the ratios of the others just for practice but the correct answer is D:C which we had already figured out

OpenStudy (anonymous):

alright thank you. i have some other questions to and i just wanna make sure i got them right cause it counts as a grade. can you check them and see if their right?

OpenStudy (sleepyjess):

yep

OpenStudy (anonymous):

for this one ik this is the answer but when i did the quadratic formula i kept getting -.34 and 1.34 but those are not the answer choices

OpenStudy (sleepyjess):

not sure about this one

OpenStudy (anonymous):

how about this one

OpenStudy (sleepyjess):

sorry i havent done this stuff in a while

OpenStudy (anonymous):

its ok...just the ones you might know how to do

OpenStudy (sleepyjess):

are you familiar with the distance formula?

OpenStudy (anonymous):

yes

OpenStudy (sleepyjess):

ok use 0, 4 as your first point and 2, -6 as your second and tell me what you get

OpenStudy (anonymous):

square root 104

OpenStudy (sleepyjess):

what does that simplify to?

OpenStudy (anonymous):

2 root 26

OpenStudy (sleepyjess):

yes

OpenStudy (anonymous):

oh so you just picked two random points?

OpenStudy (sleepyjess):

no i picked the points at the ends of the hypotenuse

OpenStudy (anonymous):

oh ok..thank you sooo much you've been a big help

OpenStudy (sleepyjess):

no problem!
