Suppose 12% of students chose to study spanish their freshman year, and that meant that there were 15 such students. how many students chose not to take spanish their freshman year?

  110

Step-by-step explanation:

If 12% studied Spanish, then 88% did not. The ratio of those who did not to those who did is ...

  88 : 12 = 22 : 3

Then the number of students who did not study Spanish is ...

   (22/3)×15 = 110 . . . . did not study Spanish

hope it you

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

what is the answer?
