A rectangular patio has a length of 12 1/2 feet and an area of 108 1/8 square feet what is the width of the patio
Ivenika [448]

Length of the rectangular patio = 12\frac{1}{2}=\frac{25}{2}

Let the width of the patio be = x

Area of the patio is given as = 108\frac{1}{8}=\frac{865}{8}

As the area of a rectangle is = length*width, so

\frac{865}{8}=(\frac{25}{2})x

\frac{865}{8}*\frac{2}{25}=x

x= \frac{1730}{200} = \frac{173}{20}

x = 8\frac{13}{20}

Hence, width of the patio is 8\frac{13}{20} feet.

<h2>Answer:</h2>

<h3>1)    \frac{1}{2}</h3><h3>3)   \frac{1}{6}</h3><h3>5)   \frac{2}{3}</h3><h3 /><h2>Step-by-Step Explanation:</h2><h3 />

1.<em> </em>Find the probability of rolling less than a four.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Outcomes lower than four</u> = 1, 2, 3

Then to answer it you need the probability in the form of a fraction.

\frac{3}{6} simplifies into \frac{1}{2}

2. Find the probability of rolling an even prime number.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Prime Numbers Through 1-6</u> = 2, 3, 5

<u>Even Prime numbers Through 1-6</u> = 2

So the probability in the form of a fraction.

<h3>\frac{1}{6}</h3><h3 />

3. Find the probability of rolling factors of 20.

<u>Probability Outcomes</u> = 1, 2, 3, 4, 5, 6

<u>Factors of 20 Through 1-6</u> = 1, 2, 4, 5

So probabilty in the form of a fraction.

\frac{4}{6} simplifies into \frac{2}{3}

What is the area of this trapezoid?
DanielleElmas [232]
Rectangle A= L*W
Triangle A= L*W*1/2

A= L*W
A=8*14
A=112

A= L*W*1/2
A= 8*3*1/2
A= 24*1/2
A= 12

A= L*W*1/2
A= 8*6*1/2
A= 48*1/2
A= 24

112+12+24= 148
