<h3>Answer: Choice D) 2.3 * 10^1</h3>

======================================

Work Shown:

(a * 10^b) \div (c * 10^d) = \frac{a}{c}*10^{b-d}\\\\(5.75 * 10^{4}) \div (2.5 * 10^{3}) = \frac{5.75}{2.5}*10^{4-3}\\\\(5.75 * 10^{4}) \div (2.5 * 10^{3}) = 2.3*10^{1}\\\\

Side note,

2.3 *10^1 = 23

A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the e
Alona [7]

In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.

The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.

Then the point has a linear speed of

(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
