OpenStudy (anonymous):

i think its C

hartnn (hartnn):

yes, C is correct :) good!

OpenStudy (anonymous):

http://prntscr.com/yn1g3

OpenStudy (mertsj):

A

hartnn (hartnn):

yeah...

OpenStudy (anonymous):

cool my answer is right thanks

OpenStudy (anonymous):

http://prntscr.com/yn1yr

hartnn (hartnn):

you tell first, what u got ?

OpenStudy (anonymous):

B

OpenStudy (anonymous):

C is wrong option

hartnn (hartnn):

yes, correct :)

hartnn (hartnn):

B is correct.

OpenStudy (anonymous):

are you sure ? iam right

OpenStudy (mertsj):

Yes. B

hartnn (hartnn):

yes, we are.

hartnn (hartnn):

why do you think, polygons are not similar ??

OpenStudy (anonymous):

sorry it C i think i typed wrong

hartnn (hartnn):

well, actually B is correct, the polygons aren't similar, i was asking you to know how you figured it out...i never said you were wrong...

OpenStudy (anonymous):

no i thought C because they have the same width

OpenStudy (anonymous):

http://prntscr.com/yn3ix

hartnn (hartnn):

what you got for that ^ ?

OpenStudy (anonymous):

i think its A

OpenStudy (anonymous):

because C is wrong

hartnn (hartnn):

nah...."corresponding" sides are proportional, so what are the largest sides of both rectangles ?

hartnn (hartnn):

both largest sides will come in numerator...A is incorrect.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

B

hartnn (hartnn):

yup.

OpenStudy (anonymous):

http://prntscr.com/yn3vn

OpenStudy (anonymous):

for this one i think B

hartnn (hartnn):

why B and why not A ?

hartnn (hartnn):

well, then i think your system is incorrect, because A clearly is correct. you can determine that just by seeing which two angles are equal.

OpenStudy (mertsj):

Absolutely it is A

OpenStudy (anonymous):

ok

OpenStudy (mertsj):

It can't be B because the corresponding parts are given in the wrong order but if you system say that A is incorrect, I would try B. The writer could have made an error.

OpenStudy (mertsj):

*your system

OpenStudy (anonymous):

Find the geometric mean of the pair of numbers. A. 44 B. 49 C. 1872 D. 54

hartnn (hartnn):

you know the formula ?

OpenStudy (mertsj):

What pair of numbers?

hartnn (hartnn):

Geometric mean of a and b is \(\sqrt{ab}\)

hartnn (hartnn):

use this formula and tell us the 2 numbers and answer you get. we'll verify.

OpenStudy (anonymous):

A is the wrong answer for this question http://prntscr.com/yn3vn

OpenStudy (mertsj):

Well as i said earlier...if the system says A (which is the correct answer) is wrong...then try B. The system was programmed by some person who may not be perfect so try B

OpenStudy (anonymous):

ok but about the other question them have not given us the means pair of numbers

hartnn (hartnn):

what have they given you then ?

OpenStudy (anonymous):

Find the geometric mean of the pair of numbers. A. 44 B. 49 C. 1872 D. 54

OpenStudy (mertsj):

You better do a screen shot of the question because something is definitely missing.

hartnn (hartnn):

yeah, where are the 'pair of numbers' ???

OpenStudy (anonymous):

http://prntscr.com/yn77v

OpenStudy (anonymous):

thats the problem no pair of numbers given

OpenStudy (anonymous):

its ok leave this one

OpenStudy (mertsj):

So you may as well just guess some other number because there is no way to know. Is there any way to contact your instructor?

OpenStudy (anonymous):

no i i have been waiting fot 2 weeks for her to check my teacher graded assignment but he is not available

hartnn (hartnn):

ok, do a wild guess...(i would guess 54) or leave it. and move on to next ?

OpenStudy (anonymous):

http://prntscr.com/yn7qv

hartnn (hartnn):

what do you think ? you know those laws ?

OpenStudy (anonymous):

i think it is sin

hartnn (hartnn):

yes, correct, now can you find x ?

OpenStudy (anonymous):

C

OpenStudy (mertsj):

Good job!!

hartnn (hartnn):

C is correct, i hope its not a guess and you actually solved it.

OpenStudy (anonymous):

i have already solved some of them iam solving som through calculator now

hartnn (hartnn):

good, more ?

OpenStudy (anonymous):

http://prntscr.com/yn910

hartnn (hartnn):

20 are too much, you can ask only those questions you have doubt with...

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

http://prntscr.com/yn910

hartnn (hartnn):

comment , what you got, everytime...

hartnn (hartnn):

if you didn't get, you can ask...

OpenStudy (anonymous):

this one iam confused

OpenStudy (mertsj):

In a 30-60-90 triangle, the side opposite the 30 degree angle is 1/2 the hypotenuse.

OpenStudy (mertsj):

y is the side opposite the 30 degree angle and 16sqrt3 is the hypotenuse. So what is y?

OpenStudy (anonymous):

8
