What is the constant of proportionality y=4.75x

The area of a square can be represented by the expression x10 Which monomial represents a side of the square?

$Area\: of \: square=side^2\\x^{10}=side^2\\side=\sqrt{x^{10}}\\side=\sqrt{x^2 \times x^2 \times x^2 \times x^2 \times x^2}\\side=x \times x \times x \times x \times x\\side=x^5$

Answer:

15.7 inches

Step-by-step breakdown:

A slice of a round pie is a sector of a circle.

The perimeter of a slice equals the arc length s plus two times the radius r. P = s + 2r

s = rθ = r(16/360) = r/22.5. Therefore,

16 = (r/22.5) + 2r = (r + 45r)/22.5 = 46r/22.5

16 × 22.5 = 46r

360 = 46r

r = 7.826

D = 2r = 2 × 7.826 = 15.7 inches

Thus, the diameter of the cake should be 15.7 inches.

Verification:

$\begin{array}{rcl}P & = & s + 2r\\& = & \dfrac{r}{22.5} + 2r\\\\16 & = & \dfrac{7.826}{22.5} + 2 \times 7.826\\\\16 & = & 0.35 + 15.65\\16 & = & 16.00\\\end{array}$
