Answer:
346 2/3 yards
Step-by-step explanation:
A football field is 100 yards long with each end zone being 10 years long, meaning the total length is 120 yards.
The width is 53 1/3 yards.
The perimeter is all the sides added, and a rectangle's, the shape of the field's, formula is p = 2l + 2w.
So if we plug it in and add it all up:
120 + 120 + 53 1/3 + 53 1/3
Perimeter = 346 2/3
The minimum of this graph is the focus of the parabola. I'm not sure with the maximum though but I think it doesn't have a maximum because the y value of the parabola will extend infinitely upward.
Answer: 112 pieces
Step-by-step explanation:
1. Rewrite 
as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:
2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:
3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:
