Tyler is making a wooden post that is 3.5 feet in length he polices marks one and 1/3 in A part on the post after making 20 marks Tyler says there is between 15 in and 16 in on the post that has not been marked

Tyler is right

Step-by-step explanation:

Given that:

Lenght of wooden plank used = 3.5 feets

Placement of tick marks = 1 1/3 inches apart

Number of tick marks placed = 20

Recall:

1 foot = 12 inches

Hence, length of wooden post in inches :

3.5 * 12 = 42 inches on length

Total length covered by the ticks placed :

1 1/3 inches * Number of ticks placed

1. 333 * 20 = 26.6667 inches

Unmarked length = length of post - length covered by tickmark

Unmarked length = (42 - 26.6666) inches

Unmarked length = 15.3333 inches.

Hence,

Within 15 - 16 inches are yet to be marked.
