What is a rational number?A rational number is one that has the form p/q, where p and q are integers and q is greater than zero. Some rational number examples are 1/3, 2/4, 1/5, 9/3, and so on.
The complete question is, Let x = 0.147 and let y = [tex]0.\overline{147}[/tex]. Is x a rational number? Is ya rational number? Which is larger, x or y?
Given the value of x is 0.147. As it can be written in the form of a fraction,
[tex]0.147 = \dfrac{147}{1000}[/tex], we can conclude that x is a rational number.
The value of y = [tex]0.\overline{147}[/tex] can also be written in the form of a fraction,
[tex]0.\overline{147} = \dfrac{147}{999}[/tex], therefore, we can conclude that y is also a rational number.
The value of y will be more as the number is repetitive, and both x and y initial three digits after the decimal are the same.

Answer: Angle 1 is 117.6⁰, the alternate angle to 1 is also 117.6⁰
X is 24.8
The Angle 2X + 12.8 = 62.4⁰, the alternate angle to it is also 62.4⁰
Step-by-step explanation: Angle (2X + 12.8 )forms 1180⁰ with Angle 1
180⁰- 117.6⁰ = 2X + 12.8
62.4⁰ = 2X + 12.8

Margo used 78 square yards of fabric to make 52 dresses last year. She used the same amount of fabric to make each dress. How many square yards of fabric did Margo use to make each dress?
The amount of square yards of fabric that Margo used to make each dress is; 1.5 sq. yds
How to Solve Algebra word Problems?We are told that;
Last year, she used 78 yd² to make 52 dresses
We are told that she used the same amount of square yards for each dress.
Thus, to find the square yards of fabric that Margo used to make each dress, we just divide 52 by 78.
Square yards used for each fabric = 78/52 = 1.5 sq. yds

Melissa has a student dictionary on her desk. Her dictionary contains 99 pages. In this dictionary, more words start with the letter "S" than any other letter, occupying 11 full pages.
If she opens up the dictionary at random, what is the probability that the page contains words starting with "S"?
Answer:
I believe it is 1/9 or 11.1%
Step-by-step explanation:
11/99 /(divided by) 11 = 1/9
1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)
so as a percent, it makes it 11.1% (repeating) or 11 [tex]\frac{1}{9}[/tex]% (which is a more exact solution)
now if you need a ratio, it would be 1:9

Answer:
1/12 + 3/12 = 4/12 (or 1/3)
Step-by-step explanation:
we want to express
1/12 + 1/4 as 1/12 + something / 12
1/12 + 1/4 = 1/12 + something/12
we already have the 1/12 part, so we're left with
1/4 = something / 12
first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3
then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.
3/3 = 1
1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12
thus, our second value is 3/12
we then have 1/12 + 3/12
if we have the same denominators, we can simply add the numerators up
1/12 + 3/12 = (1+3)/12 = 4/12

The regression line is not a good model because the residuals are not randomly distributed.
What is the residual plot?For a residual plot to represent a good model, the points on the residual plot must be randomly distributed across the coordinates.
From a regression, the residual is the difference between the observed values and the predicted values.
Using the graph, we can see that the points that follow a pattern (or curve) regression line is not a good model because the residuals are not randomly distributed.

[tex]4\left(5x-2\right)=2\left(9x+3\right)[/tex]
Answer:
Solution of equation ( x ) = 7Step-by-step explanation:
In this question we have given with an equation that is 4 ( 5x - 2 ) = 2 ( 9x + 3 ). And we are asked to solve this equation that means we have to find the value of x.
Solution : -
[tex] \quad \longrightarrow \: 4 ( 5x - 2 ) = 2 ( 9x + 3 )[/tex]
Step 1 : Removing parenthesis :
[tex] \quad \longrightarrow \:20x - 8 = 18x + 6[/tex]
Step 2 : Adding 8 from both sides :
[tex] \quad \longrightarrow \:20x - \cancel{ 8 }+ \cancel{8} = 18x + 6 + 8[/tex]
On further calculations we get :
[tex] \quad \longrightarrow \:20x = 18x + 14[/tex]
Step 3 : Subtracting 18 from both sides :
[tex] \quad \longrightarrow \:20x - 18x = \cancel{18x }+ 14 - \cancel{18}[/tex]
On further calculations we get :
[tex] \quad \longrightarrow \:2x = 14[/tex]
Step 4 : Dividing with 2 on both sides :
[tex] \quad \longrightarrow \: \frac{ \cancel{ 2}x}{ \cancel{2}} = \cancel{\frac{14}{2} }[/tex]
On further calculations we get :
[tex] \quad \longrightarrow \: \blue{\boxed{ \frak{x = 7}}}[/tex]
Therefore, solution of this equation is 7 or we can say that value of this equation is 7 .Verifying : -
We are verifying our answer by substituting value of x in given equation. So ,
4 ( 5x - 2 ) = 2 ( 9x + 3 )4 [ 5 ( 7 ) - 2 ] = 2 [ 9 ( 7 ) + 3 ]4 ( 35 - 2 ) = 2 ( 63 + 3 )4 ( 33 ) = 2 ( 66 )132 = 132L.H.S = R.H.SHence, Verified.Therefore, our value for x is correct .

In the above question, we have to solve the equation and find the value of x. So,
[tex] \\ {\longrightarrow \pmb{\sf {\qquad 4(5x-2)=2(9x+3) }}} \\ \\ [/tex]
Using distributive property we get :
[tex] \\ {\longrightarrow \pmb{\sf {\qquad 20x-8=18x+6 }}} \\ \\ [/tex]
Adding (-18x) to both sides we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad 20x-8 + ( - 18x)= \cancel{18x}+6 + \cancel{( - 18x) }}}} \\ \\ [/tex]
[tex] {\longrightarrow \pmb{\sf {\qquad 2x-8=6 }}} \\ \\ [/tex]
Now Adding 8 to both sides we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad 2x-8 + 8=6 + 8 }}} \\ \\ [/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad 2x=14 }}} \\ \\ [/tex]
Dividing both sides by 2 we get :

Question 3
What do the range and interquartile range tell you about Arnold and Jackson's training times?
Select each correct answer.
Arnold's training times are more consistent than Jackson's.
Arnold and Jackson's training times have the same spread.
Jackson's training times are just as consistent as Arnold's.
Jackson's training times have the most spread.
Range for Arnold: 18; IQR: 12
Range for Jackson: 20; IQR: 13
Jackson's had the greatest spread.
Arnold's middle 50% had the least spread
What is the Range and Interquartile Range of a Data Set?Range = Maximum value - minimum value
Interquartile range (IQR) = Q3 - Q1
Range and IQR are both measures of variability. The larger the value, the more spread the data values in a data set are.
Range for Arnold's training times = 102 - 84 = 18
Range for Jackson's training times = 103 - 83 = 20
Therefore, Jackson's training times had the greatest spread.
Interquartile range for Arnold's training times = Q3 - Q1 = 99 - 87 = 12
Interquartile range for Jackson's training times = Q3 - Q1 = 100 - 87 = 13
Thus, Arnold's middle 50% of his training times had the least spread.
The range and interquartile range tells us that, Arnold's training times are more consistent than Jackson's.

(4) NO
(5) YES
Step-by-step explanation:
According to the triangle sum theorem, the three interior angles of any triangle add up to 180 degrees. So, if we add up the three angles given, to be a triangle, they have to add up to 180 degrees.
38 + 42 + 110 = 190
So, ( (1) 38, 42, 110 ) is not a triangle becuase it adds up to more than 180 degrees (1).
20 + 40 + 120 = 180
So, ( (2) 38, 42, 110 ) is a triangle because it adds up to 180 degrees (2).
For the lengths for a triangle, the length of one side of a triangle must be greater than the difference and less than the sum of the lengths of the other two sides. This is saying:
A-B < C
A+B > C
So to find if they can be, simply plug in the values.
