Answer:7 5/12
Step-by-step explanation:
12 2/3 times 4 on both sides is become 8/12
3 1/4 times 3 on both sides is 3/12
12 8/12 minus 3 3/12 equals to 7 5/12
I don't think it's a proportional relationship because it doesn't go the origin...im not sure,Let me know
Answer:
10 ft x 10 ft
Area = 100 ft^2
Step-by-step explanation:
Let 'S' be the length of the southern boundary fence and 'W' the length of the eastern and western sides of the fence.
The total area is given by:

The cost function is given by:

Replacing that relationship into the Area function and finding its derivate, we can find the value of 'S' for which the area is maximized when the derivate equals zero:

If S=10 then W =20 -10 = 10
Therefore, the largest area enclosed by the fence is:

Answer:
perimeter=40.9ft
Step-by-step explanation:
The length at the top is 10ft,the length at the bottom is 10+4ft=14ft and the other lengths are8.9ft and 8ft
perimeter=10+14+8+8.9=40.9ft
