Answer:
117
Step-by-step explanation:
For every 3 zinc there would be 19 copper, and for every 19 copper there would be 3 zinc. There are 741 copper, so there would be 741 * 3 / 19 zinc, which turns out to be 117 zinc.

plz tell me if im wrong i hope i helped
As given r = r(max)/2
k= 50
r(max) = 0.5
By substituting the values,
r= 0.5/2 = 0.25
You have to use following equation to get a value of N
r = r(max) ( 1- N/K)
N/k = 1 - r/r(max)
N/K = 1 - 0.5 = 0.5
N= 50 × 0.5 = 25
To solve the equation 54m = 51^2 we first calculate the square of 51. We can rewrite our equation as 54m = 2601. Now we divide by 54 on both sides to get m = 2601/54. 2601 is not divisible by 54, but we can simplify 2601/54 to 289/6 by dividing by 9 on both sides.
