What is 5/6 divided by 1/7?
skelet666 [1.2K]

Answer:

5\frac{5}{6}

Step-by-step explanation:

To divide fractions, we multiply the first fraction by the <u>reciprocal </u>of the second fraction. (Seven over one)

\frac{5*7}{6*1} =\frac{35}{6}

Now, we convert the fraction into a mixed fraction.

\frac{35}{6}=5\frac{5}{6}

<em>The quotient of 5/6 and 1/7 is 5 5/6</em>

Miguel buys 100 feet of fence to enclose a rectangular area of his backyard so his dog can run freely. What is the maximum area,
sdas [7]
Suppose the length of the triangle is x, if the perimeter of the rectangle is 100 ft, the width of the rectangle will be (50-x) ft.
Area of rectangle will be:
A=length*width
A=x(50-x)
A=50x-x^2
at maximum area, dA/dx=0
thus
dA/dx=50-2x=0
solving for x we get
2x=50
x=25
thus for maximum area length=25 ft
the size of the width will be
50-x=50-25=25 ft
thus the maximum area will be:
25*25=625 sq. feet
