LAST QUESTION!! Beni's uncle is building a deck for her house that is proportional to the 24- feet by 42- feet deck he built for his house. The scale factor between his deck and her deck is 0.5. Which of the following could be a measurement for Beni's deck?

hero (hero):

Hint: Multiply each dimension by 0.5

OpenStudy (anonymous):

12 & 21 .

hero (hero):

:D Great Job

OpenStudy (anonymous):

my awsner choices are : a)8 b)16 c)18 d)28 ????

hero (hero):

Weird, but okay.

hero (hero):

I'd actually let @campbell_st help with this one.

hero (hero):

I'm definitely convinced a mistake has been made.

OpenStudy (campbell_st):

Uncle Beni 2 : 1 24 : 42 : I'd say you would halve the dimensions of the uncle's deck to get the dimensions of Beni's deck

OpenStudy (anonymous):

12 & 24 .

hero (hero):

We did that already @campbell_st and got 12 x 21

hero (hero):

I'm convinced that they made a mistake in the answer choices. It happens.

OpenStudy (anonymous):

alright . thanks guys

hero (hero):

@amberose10, if I were in your situation, I'd pick a) then complain to the teacher.

hero (hero):

a) is 8 which is 1/3 of 24

hero (hero):

The only thing close enough to pick

OpenStudy (campbell_st):

the answers suggest that the ratio is uncle :beni is 3:1

hero (hero):

@amberose10, are you still here?

hero (hero):

I so envy this last problem. How can they make a mistake on the last problem. I bet a teacher hand-inputted these questions into a computer.

hero (hero):

amber rose must be panicking right now.

OpenStudy (saifoo.khan):

input. @Hero

hero (hero):

I've inputted enough. It's someone else's turn. At least say something relevant to the problem and the answer choices.

OpenStudy (anonymous):

i asked my mom ... i know for a fact its not 18 . bc i picked that & it was incorrect .

hero (hero):

And you didn't pick a)

hero (hero):

Wow, you amaze me. I said pick a) not 18

hero (hero):

I keep telling you that NONE of the answer choices are correct.

OpenStudy (saifoo.khan):

Lol.

hero (hero):

But you just sit there in silence like you don't believe me.

hero (hero):

I basically have everyone from OS looking at this question. If someone actually had an objection, they would have posted it by now.

OpenStudy (anonymous):

I understand . i will tell the teacher .

hero (hero):

You should trust me a little more. It's not like I haven't been helping you.

OpenStudy (anonymous):

i picked 18 before you said pick A . It was a timed test .

hero (hero):

@amberose10 , no one said pick 18. I don't know why you did that.

hero (hero):

Anyway, it doesn't matter because the teacher will recognize that the last one is a mistake. btw, I suspected you were taking a test the whole time.

OpenStudy (anonymous):

yeah sorry !!

hero (hero):

You realize you could be suspended for admitting taking a test on OS?

OpenStudy (anonymous):

No . i mean i took a different test while figuring out the study sheet on here . i took a drivers liscence course test . i never asked those questions
