To solve this problem, let us first assign variables. Let
us say that:
x = volume of 67% herbicide solution
y = volume of 46% herbicide solution
The total volume should be 42 liters therefore:
x + y = 42
x = 42 – y --> 1
The component mass balance on the pure herbicide would
be:
0.67 x + 0.46 y = 0.55 (42) --> 2
Substituting equation 1 to 2:
0.67 (42 – y) + 0.46 y = 23.1
28.14 – 0.67 y + 0.46 y = 23.1
- 0.21 y = - 5.04
y = 24 L
Calculating for x using equation 1:
x = 42 – 24
x = 18 L
Therefore we only need 18 L of the 67% herbicide
solution.
Answer:
A. 18 L
I believe the answer is (2, 2)
You would want to divide 216 by 18 and by doing that you would get 12.
Answer:
y = (3/2)x - 12
Step-by-step explanation:
Recall that the general equation for a linear function may be written in slope-intercept form:
y = mx + b
where m = slope and b = y-intercept
In this case, it is given that slope = m = 3/2 and y-intercept = b = -12
substituting these values into the general equation:
y = (3/2)x + (-12)
or
y = (3/2)x - 12
Answer:
○ C. 
Step-by-step explanation:
Wherever the graph intersects the x-axis is considered your zero [x-intercept], therefore you have your answer:
![\displaystyle [0, 0], [2, 0], and\: [4, 0]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B0%2C%200%5D%2C%20%5B2%2C%200%5D%2C%20and%5C%3A%20%5B4%2C%200%5D)
