Answer:

I'm not quite sure how to interpret the above equation so I solved it two ways and you can pick which way you meant.

Step-by-step explanation:

2 \times  \frac{1}{2}  - 1 \times  \frac{3}{8}  \\  \frac{2}{2}  -  \frac{3}{8}  =  \frac{(8 \times2) - (2 \times 3)}{2 \times 8}  \\  \frac{16 - 6}{16}  =  \frac{10}{6}  =  \frac{5}{3} = 1\frac{2}{3}

2 \frac{1}{2}  - 1 \frac{3}{8}  \\  \frac{5}{2}  -  \frac{11}{8}  =  \frac{(8 \times 5) - (2 \times 11)}{2 \times 8}  \\  \frac{40 - 22}{16}  =  \frac{18}{16}  =  \frac{9}{8} = 1\frac{1}{8}

A rectangular field has dimension of 91 feet by 60 and 1/3 feet what is the area of the field
Oliga [24]

Answer:

Area = 91*\frac{181}{3}=5490\frac{1}{3} square feet

Step-by-step explanation:

The area of a rectangle is given by the formula:

A = length * width

Where length is 91 feet and width is 60\frac{1}{3}  feet

Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:

a\frac{b}{c}=\frac{(a*c)+b}{c}

Hence,

60\frac{1}{3}=\frac{181}{3}

So, the area is:

Area = 91*\frac{181}{3}=5490\frac{1}{3} square feet

You are to run a conduit diagonally across a parking lot that is 200 ft long and 60 ft wide. How much conduit will you need to c
torisob [31]

Answer:209ft

Step-by-step explanation:

We let y be the unknown value, which is length of conduit.

200^2 + 60^2=y^2

40000 + 3600=y^2

43600=y^2

Square both side

y= sqrt(43600)

y= 208.8061 ft

y=209 ft
