contract to start next. They will make £200 extra profit per day in the new contract. They are considering completing the existing contract asap but hiring more painters is difficult and only three more painters are available. Every 6 painters have to have 1 supervisor and each supervisor will cost £80 extra per day.
a) Analyse the extra costs/profitfor the contractor if they decide to complete the project by 15 painters.
In the next project: Two supervisors and twelve painters together will cost £1056 per day, whilst three supervisors and fourteen painters together will cost £1288 per day. Then:
b) Find, by the analytical solution of a set of simultaneous linear equations, the earnings for a supervisor and a painter.
c) Find, by the graphical method for the solution of a set of simultaneous linear equations, the earnings for a supervisor and a painter.
d) Use matrices to solve the same set of simultaneous equationsto find the earnings for a supervisor and a painter.
Thanks

A 0.5130g aspirin tablet which was dissolved in 95% ethanol required 27.98mL of 0.1000M NaOH for neutralization. then an additional 42.78mL of 0.1000M NaOH was added and the solution was heated to hydrolyze the acetylsalicylic acid. After the reaction mixture was cooled, the excess base was back-titrated with 14.29mL of 0.1056M Hcl. How many grams of acetylsalicylic acid are in the tablet? What % w/w of the tablet is acetylsalicylic acid?

and the radius of the sphere is 8m, then
h cubed minus 24h squared plus 205=0
Then find h, the height of the dome, given that its value is between 1m and 6m.
I got the answer to be around 3.14m high, but can anyone be more accurate. Thanks.
