So it would be 5/12 which comes out to 0.41 so 41%
I think it’s 90% cuz it’s 45/50 therefore 90/100
Answer:
Brian Peters worked for total of 45 hours.
Step-by-step explanation:
Let the total number of hours worked be 'x'.
Now Given:
Hours spent on other projects = 18 hours.
Also Given:
60% of a week's time working on drawings for a new apartment building.
Hours spent on new apartment building = ![60\%\times x = \frac{60}{100}x=0.6x](https://tex.z-dn.net/?f=60%5C%25%5Ctimes%20x%20%3D%20%5Cfrac%7B60%7D%7B100%7Dx%3D0.6x)
We need to find the total hours worked.
Solution:
Now we can say that;
total number of hours worked is equal to sum of Hours spent on new apartment building and Hours spent on other projects.
framing in equation form we get;
![x=0.6x+18](https://tex.z-dn.net/?f=x%3D0.6x%2B18)
Combining like terms we get;
![x-0.6x=18\\\\x(1-0.6)=18\\\\0.4x=18](https://tex.z-dn.net/?f=x-0.6x%3D18%5C%5C%5C%5Cx%281-0.6%29%3D18%5C%5C%5C%5C0.4x%3D18)
Now Dividing both side by 0.4 we get;
![\frac{0.4x}{0.4}=\frac{18}{0.4}\\\\x=45\ hrs](https://tex.z-dn.net/?f=%5Cfrac%7B0.4x%7D%7B0.4%7D%3D%5Cfrac%7B18%7D%7B0.4%7D%5C%5C%5C%5Cx%3D45%5C%20hrs)
Hence Brian Peters worked for total of 45 hours.
R(x)= -x2+3x is x=0
s(x)= 2x+1 is x= -1 over 2
(-1-2) (0)
