Answer:
1.75 feet
Step-by-step explanation:
48 ÷ 2 = 14
14 ÷ 2 = 7
7 ÷ 2 = 3.5
3.5 ÷ 2 = 1.75
Answer:
70.83% entrants will have distances between 150 and 160.
Step-by-step explanation:
This question is incomplete without an attachment; here is the attachment enclosed with the answer.
From the graph attached,
Number of entrants having distances between 150 and 160 feet = 8 + 9 = 17
Number of entrants between 140 and 200 feet = 8 + 9 + 4 + 2 + 1 = 24
Percent of entrants having distance between 150 and 160 feet = 
= 
= 70.83%
Therefore, 70.83% entrants will have distances between 150 and 160.
Solution is in the picture
Good luck :)
The perimeter is 4/3x(3), or 12/3x.
The area is (2x+2)^2
Therefore, we must solve the equation
4x^2+4x+1= 0
This eventually factors to x = -0.5.
