Total ratio = 2 + 3 + 5 = 10
Sum of angles in a quadrilateral is 360
4th angle = 130
360 - 130 = 230
Sum of remaining 3 angles must be equal to 230
1st angle 2/10 * 230 = 46
2nd angle 3/10 * 230 = 69
3rd angle 5/10 * 230 = 115
Adding all angles together 46 + 69 +115 + 130 = 360
Answer:
the earned value of the project is $9,900
Step-by-step explanation:
The computation of the earned value of the project is shown below:
As we know that
CPI = Earned value ÷ Actual cost
1.1 = Earned value ÷ $9,000
So, the earned value is
= 1.1 × $9,000
= $9,900
hence, the earned value of the project is $9,900
We presume you want to find values of x that make this true.
Subtract the right side and factor:
![2x^2-5x=0\\\\x(2x-5)=0\\\\\bf{x=0\qquad\text{or}\qquad x=\dfrac{5}{2}}](https://tex.z-dn.net/?f=2x%5E2-5x%3D0%5C%5C%5C%5Cx%282x-5%29%3D0%5C%5C%5C%5C%5Cbf%7Bx%3D0%5Cqquad%5Ctext%7Bor%7D%5Cqquad%20x%3D%5Cdfrac%7B5%7D%7B2%7D%7D)
Once you have factors whose product is zero, you can find the values of x that make those factors zero. A product can only be zero if one or more contributing factors is zero.
To solve 2x-5=0, you can add 5 then divide by 2:
... 2x -5 = 0
... 2x = 5
... x = 5/2
