6 is equal to 42/7, and 3 and 5/7 is 26/7 so 42-26 = 16/7 which is also 2 and 2/7 ths

60 days / 8 workers = 7.5

60 days - 12 days of work done = 48

48 x 7.5 = 360

Answer: $\theta =\arctan \mu$

Step-by-step explanation:

we know force sin component would oppose the weight of object thus normal reaction will not be W rather it would be

$N=W-Fsin\theta$

therefore force cos component will balance the friction force

F $cos\theta$ = $\left ( \mu N\right )$

F $cos\theta$ = $\left ( \mu \left ( W-Fsin\theta \right )\right )$

F= $\frac{\mu W}{cos\theta +\mu sin\theta}$

F will be smallest when $cos\theta +\mu sin\theta$ will be maximum

and it will be maximum when we differentiate it to get

$\theta =\arctan \mu$
