The central angle of each sector is 360°/8 = 45°, so the central angle between a vertex and the apothem is half that, 22.5°. The length of half a side will be
s/2 = (2 ft)*tan(22.5°) ≈ 0.828427 ft
The area of each of the 8 sectors will be this multiplied by the apothem (2 ft), so is 1.6568 ft². The total area of the 8 sectors is then
8*1.6568 ft² ≈ 13.25 ft²

A bike store sells scooters at a 54% markup. If the store bought each scooter for $29.25, what is the resale price to the neares

7nadin3 [17]

The purchasing price of the store = $29.25.

They want to resale it at 54% markup of the purchasing price.

54% of 29.25 = 0.54 × 29.25.

On multiplying 0.54 and 29.25, we get 15.795.

Resale price = The purchasing price + Markup

= 29.25 + 15.795.

On adding 29.25 and 15.795, we get 45.045.

We can round it to 45 to the nearest dollar.

<h3>Therefore, the resale price to the nearest dollar is $45.</h3>

Answer:

(y+1)/5

Step-by-step explanation:

you meant f^-1(x) ?

let y= 5x-1

Make x subject of formula

y+1=5x

x=(y+1)/5

f^-1(x)=(x+1)/5 replace y by x
