mark is an auto dealer he sold a car and made a loss of 10% if his loss was $150000 A calculate how much he sold the car for B what was his cost price

A. he sold the the car for 1350000

B. his cost price is 1500000

Step-by-step explanation:

A. 150000---> 10%

x> 90%

cross multiplication: x=150000×90/10=1350000

B. 10%( price) +90%(price)

1350000+150000=1500000

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
