Answer:
150 mL
Step-by-step explanation:
Let x represent the quantity of 75% solution needed. The total amount of alcohol in the 60% mixture will be ...
75%·x + 10%·45 = 60%·(x+45) . . . . . there will be x+45 mL of solution in the end
0.15x = 22.5 . . . . . . . . . . . . . . . . . . . . simplify, subtract .60x+4.5
22.5/0.15 = x = 150 . . . . . . . . . . . . . . mL of 75% solution needed
You will need 150 mL of the 75% solution.
X>-1/3, the graph would be filled everything to the right of -1/3 on the x axis
There will be one solution. To solve that:
1. Get the y alone by switching the places.
6x+y=2 > y=2-6x
-18x+3y=12 > 3y=12-18x > Then divide 3 on each number > y=4-6x
After doing that, you can solve this in graphing or algebra way.
Ima do the algebra way:
SO we have 2 system of equations. Now pick one equestion.
I will pick, y=2-6x. Now Ima replace the Y with the other equation y=4-6x >
4-6x=2-6x.
Now solve. And get > 0 aka Infinite Solution.
<u>Explanation:</u>
Business intelligence dashboard is the data visualization tool which can be seen on a single screen. The information that needs to be presented can be done with the BI dashboard it is a technology driven process. It helps the business to maintain the performance KPI's, metrics and other inputs. It helps to simplify the complex set of information in a business.
The real time data can be viewed and understood by the entire team. The sharing of data is also easy through BI dashboard.
