Which proportion represents the problem below?
17% of a number is 43. What is this number?
A. 17/43=n/100
B. n/17 = 43/100
C. n/43= 17/100
D. 43/n= 17/100

D

Step-by-step explanation:

17% : 43

100% : n

43/n = 17/100

correct option is D, 43/n = 17/100

Step-by-step explanation:

Let the missing number be n

17% of n = 43

= 17/100 n = 43 =17/100n = 43/1

Cross multiply to get: 17n = 43 x 100, which is the same as 43/n = 17/100

Check the options stated a) 17/43 = n/100, if we cross multiply, it gives 43n = 17 x 100 ...wrong

b) n/17 = 43/100 gives 100n =43 ×17

c) n/43 = 17/100 gives 100n = 43 x 17

d) 43/n = 17/100 gives 17n = 43 x 100

I hope this is clear. Please mark as brainliest answer.

i think it is x = 1.2

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
