Kelly has 15 blue bracelets and 12 green bracelets. What is the ratio of Kelly’s blue bracelets to green bracelets? A) 3 : 4 B) 4 : 5 C) 4 : 3 D) 5 : 4

D) 5 : 4

Step-by-step explanation:

Don’t worry, this isn’t too difficult. First take 15 and 12. Find the first number that they can both be divided by. In this case, both 15 and 12 can be divided by 3. 15 divided by 3 is 5 and 12 divided by 3 is 4.

Remember to order the numbers the right way. Because the blue bracelets are mentioned first, the 5 should come before the 4. Making the answer 5 : 4.

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
