Cosmo is NOT right i got 9/16

the answers are
1.c
2.c
3.b
4.b
5.c
6.b
7.c
8.b
9.d
10.d
11.c
12.b
13.b
these answers are so ridiculous but i copied them off the test so uh there you go!!
14.b
15.b
16.b

1. correct

2. p/6 = 7/8 ---> p= 42/8 = 5.25
3. correct
4. 521 miles in 14 hrs = 521/14 mph = 37.21 mph
Your answer should have hit you as totally
unreasonable.
5. 33.6 gallons in six months --> 33.6/6 gal/mon
= 5.6 gallons/month
6. .81 euro = 1 dollar
1 eur = 1/.81 dollars
222 euros = 222(1/.81) dollars = $274.07
7. perimeter is 20 cm, increased by a factor of 4
since perimeter is a linear function, the new perimeter
is 4(20) or 80 cm
8. area is proportional to the square of a side
increased by a factor of 3^2 or 9 times as big
---> 9(13) m^2 = 117 m^2
9. can't tell, obviously base on some diagram
10. original width = 30 , new width = 10
factor = 1/3.
How can you possibly have a factor of 3, your choice, if the width decreased ??
11. YEAHHH, YOU GOT ONE RIGHT
12. 30/15 = 2 and 45/15 = 3
so 2 by 3 , which is the first choice
13. YEHHH, ANOTHER ONE RIGHT

4 right out of 13 !!!
--- by just guessing you would have 4 correct.

On your own for the short answer questions

Ok I’m back lol

17)First step you add 10 and six to get 16 then you divide the amount of golf balls you want to add which is 112 x 16 which gives you seven then you multiply the amount of white golf balls by seven which is 10×7 which equals 70 then you multiply the amount of the number of striped golf balls, 6 by seven which equals 42.

18) I have to do is multiply each number in each coordinate by two so V‘(12,6), W’(-4,8), X’(-6,-4), and Y’(6,-10) (these are the coordinates after they’ve already been multiplied by two ;))

19)(I’m not 100%sure about this one)
No the polygons are not similar because when you divide 35 5.2 you get 5.7692 and when you divide 8 by 2.4 you get 3.3333 so they are not similar.

Hope this helps if anyone even scrolls this far to find this answer

Okay so if your ALL the way down here that means you REALLY really want the answers, so here it is. The 100% correct answers as of 11/30/2020 Conexus academy Lesson 8 Unit 5 Unit test: (PS, don't listen to the guy above me, he's wrong!)

Do ya'll not realize (A) that there is a different set of questions for everyone

(B) that Connexus changes the answer or rearranges the answer for each test to prevent people from "cheating"
Personally, I don't care what you do because at the end of the day it doesn't affect me at all and I find the people on here that criticize others for coming onto this website for answers annoying:/ But anyway if you are one of the people who give answers make sure to give the date, and for each question actually write out the answers instead of just saying A, B, C, or D.

Dear person reading this,

The questions are different for everyone and I assure you that have a 99.9 percent chance of getting at least one question wrong so if I was you I would get the BRAINLY app and scan your questions
You’re welcome

@Jaja no he wasnt, no one is right

OOF IS NOT CORRECT. i got 4/16 BECAUSE OF HIM. DO NOT USE HIS ANSWERS
