there are 40 students in a class girls make up 60% of the class 25% of the girls wear glasses how many girls in the class wear glasses?​

8 girls wear glasses

Step-by-step explanation:

40*60/100=24

25/100*24=8

6

Step-by-step explanation:

60/100 * 40 = 24

so 24 students are girls

25% of 24 is

either 24/4=6 or

24x25/100 = 6

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
