There was 145 children that went to the park today and 60% of the children were boys. how many of the children were girls at the park?

First find 60% of 145 =

60% of 45 equals 87.

Now subtract 87 from 145.

145 - 87 = 58

So there were 58 girls.

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
