2 answers:
Answer:
17 links
Step-by-step explanation:
<em>1. </em>13 Links and 17 links are rusted. Since we need to find out the number of links that are not rusted, we need to add 13+17.
<em>a.</em><em> 13 + 17 = 30</em>
2. Now since we added the number of lines rusted, we now should subtract the ones rusted and the one not rusted to get the answer.
a. 47-30 = 17

Answer:
Part A)
Each diagonal is about 9.43 feet.
Part B)
In total, Wally needs about 736.02 feet of wood.
Step-by-step explanation:
Part A)
Since each vertical board has a width of 8 inches, for one section with 12 vertical boards, the total width will be 8(12) = 96 inches.
96 inches is the same as 96/12 = 8 feet.
We are also given that the horizontal pieces will be 5 feet apart.
To find the diagonal, we can use the Pythagorean Theorem. The 8 is the base and 5 is the height. Therefore:
Compute:
Taking the square root, we acquire:
So, each diagonal is about 9.43 feet.
Part B)
For each section, we have two horizontal pieces (each 8 feet) and one diagonal piece (each √89 feet).
Therefore, for one section, we will need a total of:
Then for 30 sections, we will need:
Approximate:
Wally will need about 736.02 feet of wood in total.
