Complete the patterns of equivalent ratios by filling in the gaps. 64:16
32:8
_ : _
_ : 2
4 : 1

64:16

32:8

16: 4

8:2

4:1

Step-by-step explanation:

Looking at the pattern, we have to multiply the value on the right by 4 to get the value on the left

Also, as we go down, we divide each of either sides by 2 to get the next term

in line

So we fill in the ratio as follows;

64:16

32:8

16: 4

8:2

4:1

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
