Answer:
A is 146 and how much is 1 unit for B
Step-by-step explanation:
The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
Answer:
230 million
Step-by-step explanation:
I took the application
So.. first off.. let's keep in mind that if 30% of acid is there in a solution, say the solution is some amount of liquid and 30% of that total liquid only is the acid, so if the amount of the liquid is say "x", then 30% of that is just (30/100) * x, or 0.3x.
now, we'll do the same for the 55% and the 45%, use the decimal format to get how much quantity in the substance is of acid.
now, whatever "x" and "y" are, we know that
x + 60 = y, and we also know that
0.3x + 33 = 0.45y.
Answer:
x > 16
