A rational number can always be represented as a fraction.
5.2 = 52/10 
5.5 = 55/10

A number between them would be 54/10 since 54 is between 52 and 55.

An irrational number cannot be represented as a fraction. A good example of an irrational number is the square root of a number.
sqrt(5.2^2) = 5.2  ----> 5.2^2 = 27.04
sqrt(5.5^2) = 5.5  ----> 5.5^2 = 30.25

The square root of a number between 27.04 and 30.25 will be an irrational number between 5.2 and 5.5
sqrt(28) = 5.2915...

How do you prove theorems behind two parallel lines cut by a transversal?
LenaWriter [7]
The way to do it can be explained like this:
Say AB and CD are the two parallel lines cut by a transversal at E and F respectively.
 Then the pairs of alternate interior angles are:
Angle(AEF) and Angle(DFE)
Angle(CFE) and Angle(BEF)
Now lets prove if this is true:
<span>Angle(CFE) +Angle(DFE) = 180
(linear pair)
Also
Angle(CFE) +Angle(AEF) = 180
(Corresponding angles)
</span><span>Equate the above results:
Angle(CFE) +Angle(DFE) = Angle(CFE) +Angle(AEF)
</span><span>Angle(DFE) = Angle(AEF)
</span>Happens the same with
<span>Angle(CFE) = Angle(BEF)
</span>Hope this is very useful for you

20 POINTS !!!!!!

I think the question is asking for the cost (C) when we already know that the sell price (S) is $24
So C+M=S
C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents

FIND AREA OF SHADED SEGMENT. WILL GIVE BRAINLIEST FOR CORRECT ANSWER
Xelga [282]
By geometry,
area \: of \: shaded \: region \:  =  (\: area \: of  \: square \:  -  \: 2 \times (area \: of \: semi - circles)) \div 2
=  ({l}^{2}  - 2 \times \pi  \times {r}^{2} ) \div 2
l = 6 \\ r = l \div 2 = 3
= (36 - \pi \times  {3}^{2} ) \div 2
= 3.86
area of shaded region = 3.9
