Answer:

5 boys

Step-by-step explanation:

boys to girls in math class = 3/12

3/12 can be reduced to 1/4

In the science class, the ratio is the same but there is a total of 20 girls.

Multiply the fraction 1/4 by 2/2, 3/3, 4/4, 5/5, etc. until you get x/20. Then you have 20 girls. x is the number of boys.

1/4 = 2/8 = 3/12 = 4/16 = 5/20

In science the ratio of 1/4 is the same as 5/20, so there are 5 boys.

I NEED HELP PLEASE! THANKS :)

Answer:

 $y = 2 \: cos \: (\frac{1}{3} x)$ 

option C is the right option.

Explanation:

General expression of a cosine function is:

y=A cos k X

where A is amplitude and 2 pi/k is its period.

In our case,

 $- y = 2 \: cos \: (\frac{1}{3} x) \:$ 

has :

 $amplitude = 2 \\ period = 2\pi \times 3 = 6\pi$ 

hence, the right answer is of option C

hope this helps...

Good luck on your assignment..
