The sound off siren company tests every fifth siren for sound quality and every eighth siren for mechanical quality. the daily output is 350 sirens. what percentage is tested for mechanical quality? what percent is tested for both types of quality at the same time?

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

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man
