In a quadrilateral ABCD, AB || DC and AD || BC. Find the perimeter of triangle COD if the diagonals of the quadrilateral interse
aalyn [17]
Draw a diagram as shown below.

The diagonals are equal in length. Because AB || DC and AD || BC, the quadrilateral is a square.

Because the diagonals bisect each other at O, therefore
DO = BO = 10.
Likewise,
AO = CO = 10

Because AB = 13, therefore DC = 13.
The perimeter of ΔCOD is CO + CD + DO = 10 + 13 + 10 = 33 in

Answer: 33 in

One-fifth of the sum of the numerator and the denominator of a particular fraction is8. If the numerator is subtracted from 22,
Alex_Xolod [135]

Answer:

The original fraction is 13/27

Step-by-step explanation:

Let the fraction be x/y. This means that the numerator is x and the denominator is y.

One-fifth of the sum of the numerator and the denominator of a particular fraction is 8. This means that

1/5 (x+y) = 8

Cross multiplying with 5,

x+y = 5×8 = 40 - - - - - - - -1

If the numerator is subtracted from 22, the original fraction becomes 1/3. This means that

(22-x)/y = 1/3

Cross multiplying with y and 3,

3(22-x) = y×1

66-3x = y - - - - - -2

Substituting y = 66-3x into equation 1, it becomes

x + 66 - 3x = 40

x -3x = 40-66

-2x = -26

x = 26/2 = 13

y = 40 - x = 40 - 13

= 27

The original fraction is 13/27

3) There are 35 people living in poverty and 42 people not living in poverty
REY [17]

Answer:

John is not correct

Step-by-step explanation:

<em>(Unless you meant 5:6)</em>

Make the base question into \frac{35}{42}

simplify as much as possible. I found the Greatest Common Denominator (GCF) of<em> 35</em> and <em>42</em>, which was<em> 7</em>

divide <em>35</em> and <em>42</em> by the GCF<em> (7)</em>, and you should get 5:6 as your answer.
