The density of a metal is 12.5g/cm3.find the mass of the metal if the volume is 200cm3 . give your answer in kilograms

2.5kg

Step-by-step explanation:

density= mass/ volume

rearrange:  

mass= density* volume  

12.5*200= 2500g

2500/1000= 2.5

2.5kg

idk i would have to be there to under stand it

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
