The full circle has arc 360 degrees
so length of arc of 140 degrees will be , by proportion, (60 pi * 140 ) / 360

Answer:

4 pairs of sock and a little bit of left over change.

Step-by-step explanation:

24.95 + 5.95x = 50

-24.95 -24.95

5.95x=25.05

/5.95 /5.95

x = 4.21

We drop the 0.21 because you cant have 0.21 pairs of socks and we get:

x=4

I need help breaking this down

sergeinik [125]

Answer:

see explanation

Step-by-step explanation:

Given

2cosΘ - $\sqrt{2}$ = 0 ( add $\sqrt{2}$ to both sides )

2cosΘ = $\sqrt{2}$ ( divide both sides by 2 )

cosΘ = $\frac{\sqrt{2} }{2}$

Since cosΘ > 0 then Θ is in first and fourth quadrants, hence

Θ = $cos^{-1}$ ( $\frac{\sqrt{2} }{2}$ ) = $\frac{\pi }{4}$

Θ = 2π - $\frac{\pi }{4}$ = $\frac{7\pi }{4}$

solutions are Θ = $\frac{\pi }{4}$ , $\frac{7\pi }{4}$

175-20%= 35 off

175-35=140

140*8% tax= 11.20 tax

140+11.20= 151.20

151.20*18% tip= 27.216
