Dude I asked my teacher she said no.

That is the wrong answer.

1. 360 degrees/60 degrees = 6

The circumference of the circle is 20pi

20pi/6 = 10pi/3

so C

2.360 degrees/60 degrees = 6

The area of the circle is 100pi

100pi/6 = 50pi/3

so A

Melody you forgot a ten in your prime factorization, but it is fine i get it now. Thanks!

According to my understanding surface waves have atoms that move perpendicular to the direction of the wave. They just move up and down.

What do you mean by "Circumference of the sum"

I used the https://ptable.com 

O2=2(15.999)=31.998

N2=2(14.007)=28.014

NO2=14.007+2(15.999)=46.005

Lets solve one by one using unit conversions

O2=1 mol/31.998 g

88g of O2= 88*1 mol/31.998g

88/31.998 moles of O2=2.531408213013313332083 moles of O2

N2=1 mol/28.014

88g of N2=88*1 mol/28.014

88/28.014 moles of N2=3.141286499607339187549 moles of N2

NO2= 1 mol/46.005

12g of NO2=12*1 mol/46.005

12/46.005 moles of NO2=0.2608412129116400391262 moles of NO2

0.2608412129116400391262/5.933535925532292558758=0.04396050115568149888328. To make life simpler, im going to round it to

0.04396.

Fractional form is 

1099/25000

I dont know if this is correct-It doesnt seem like it-but I tried 

f(x)=3x^2+10x-8,g(x)=3x^2-2x

(f/g)(x)=3x^2+10x-8/3x^2-2x

(3x-2)(x+4)/x(3x-2)

the 3x-2 cancel

x+4/x

It is the third answer

f(x)=g(x), so x^2-6x+8=x-2

x^2-7x+10=0

(x-5)(x-2)=0

x=5,2

Thank You!
