Answer:
153.1ml
Step-by-step explanation:
We have 12.5ml of acid in the solution.
If we want this to be 3% then we can divide this value by 3 and times by 100 to get the total value.
416.6ml total solution amount
415.6-12.5-250=153.1
Set up a system of equations first
W: number of women
M: number of men
50=w+m
3m-2=w
Solve in by plugging in one equation into the other
50=(3m-2)+m
50=4m-2
52=4m
m=13
So if m=13 plug it bag into one of the two equations at the beginning
50=13+w
W=37 women
Answer:6/25
Step-by-step explanation:
Y varies inversely as x²
Y =k/x²
Y= 6, x = 30
Substitute the value of y and x
6 = k/30²
Make k the subject of the formula
k = 6/900
k =1/150
The equation connecting Y and x is
Y = x²/150
When x = 6
Y= 6²/150
Y= 36/150
Y= 6/25
