A high school track is shaped as a rectangle with a half circle on either side.
Ilia_Sergeevich [38]

Answer:

Option (3)

Step-by-step explanation:

Track is shaped as a rectangle with a semicircle on either side.

Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.

= 2(96) + 2πr

= 192+2\pi (\frac{35}{2})

= 192 + 35π

= 192 + 109.9

= 301.9 m

Since, Jake plans to run four laps.

Therefore, distance covered by Jake = 4 × 301.9

                                                              = 1207.6 m

Option (3) will be the correct option.

il63 [147K]

Simplify 7(x-4)-3x+2x:

4x-26=3x-2-x

Subtract x from 3x:

4x-26=2x-2

Move all terms containing x to the left:

2x-26=-2

Move all terms not containing x to the right:

2x=24

Divide by 2 and simplify:

x=12
