What quantity of a 50% acid solution must be mixed with a 20% solution to produce 600 mL of a 45% solution?
Naddika [18.5K]

Answer:

400 mL

Step-by-step explanation:

0.50x + 0.20(600-x) = 0.40*600

50x + 20*600 - 20x = 40*600

30x = 20*600

x = 20*20

x = 400 mL

Math question please show work for brainliest :)
yKpoI14uk [10]
Hello!
First of all you look at how many X's the line moves by, in this case it is -3

Then you look at how many y's the line moves by, in this case it is -2

Then you add together the number of X's moved and the number of y's moved:
-3x + -2y
( adding a negative number is the same as subtracting that number)
thus the answer is A. -3x-2y

Hope This helps! :)

What is the perpendicular distance from the line y= 2x-3 to the point (8,3)
Liula [17]
Find the perpendicular line then find the intersection then find the point

perpendicular lines have slopes that are perpendicular
the slopes multiply bo -1

y=mx+b
m=slope
y=2x-3
2 is slope

2 times what=-1
what=-1/2


the equation is
y-3=-1/2(x-8) or
y=(-1/2)x+7

find intersection
at (4,5)
distance bwetweeen (8,3) and (4,5)
D=\sqrt{(8-4)^2+(3-5)^2}
D=\sqrt{(4)^2+(-2)^2}
D=\sqrt{16+4}
D=\sqrt{20}
D=2√5
distance= 2√5
