Geometry, circles and radius
25 points

Below in bold.

Step-by-step explanation:

Part A.

There are  18 sectors in the circle  so each arc  goes through  360/18 = 20 degrees.

The passenger passes through 4 arcs so that is 80 degrees.

The distance travelled from M to J =  (80/360) * the circumference.

The circumference = 2πr = 2 * 200 * π

= 400π feet.

So the distance = (80 * 400π) / 360

= 279.25 feet.

Part B.

The distance for 2 revolutions = 2 * 2 * π  * 200

= 800 π

= 2513 feet.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
