Carlos has a 1.2 meter long piece of wood .he wants to cut it into 3 equal lengths. how long should each piece be in millimeters

MILLI = 1000th, so one millimeter is 1000th of a meter, namely, in 1 meter, there are 1000 mm.

so in 1.2 meters there are 1.2*1000 = 1200 mm.

to cut them into 3 equal sides is just a plain division, 1200 ÷ 3, gives us 400 mm.

and we can convert that back to meters by 400/1000 = 0.4 meters.

answer:

what is your question that you ask

step-by-step explanation:

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
