The school drama club sponsored a guessing game at a fair. they put some blue marbles and some green marbles in a box. people had to guess how many of each were in the box given in two clues. 1. there were 52 marbles total in the box. 2. the ratio of blue marbles to green marbles was 8 : 5

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

hi, i am not sure about this one but i think its d,

hope this !

question is incomplete.

correct answer:

i^31 = -i
