You work 8.5(5) hours a week = 42.5 hour and take 12$/hour so 

42.5(12)=510$ so your check is 510$ per week!

Hope this helps!

Full circle perimeter is 2πρ so here is 2πPO => 2π5 = 10π but we have 3/4 of full curcle so 10π(3/4)=15/2π 

15/2π is the perimeter of circular disk we want and PO + OQ so Finally perimeter of the shaded region is:

15/2π + 5 + 5 = 15/2π + 10 or if π= ~3.14 we have ~ 33.5619449019234493 

Hope this helps!

Happy Birthday Hectictar But post it like off-topic

So we take this first (x-1)/3<5/7 and after this 5/7<(x+4)/5

(x-1)/3 < 5/7                                                5/7<(x+4)/5

7(x-1) < 3(5)                                                5(5) < 7(x+4)

7x - 7 < 15                                                  25 < 7x + 28

7x < 22                                                       -3 < 7x

x<22/7                                                        -3/7 < x 

or x< 3.1...                                                 or x > -0.4...

We find  -0.4 < χ < 3.1 

so the answer : integer values ​​satisfy is 0,1,2,3

Hope this helps!

I believe in you!

12+n is different and find the reason why... :p

Justified if because i do it!

I think you mean 2/3a and not 2/(3a)

2/3a = 1/6 + 2/6 

4/6 a = 3/6 

a = 3/6(6/4)

so a= 3/4 

Why this is a trick question? If you want p.m. me !
