An insect can fly 4.5 meters in 9 seconds. How fast is that in kilometers per hour?

1000

Step-by-step explanation:

4.5x60=27 meters

meter=27 meters

27 divided 0.027=1000

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
