The difference between 0.2 and 0.2 repeating is that 0.2 is that rational number and 0.2 repeating is the rational number.
What is defined as the rational and irrational numbers?Irrational numbers are real numbers that can't be depicted as a ratio-like fraction, p/q, where q and p are integers. In other words, irrational numbers are real numbers which are not rational numbers.Rational numbers are written in the form p/q, where p and q are any integer and q 0 respectively.Q represents the set of rational numbers. A rational number is one that can be demonstrated as a fraction with both the numerator and denominator being integers.For the two given values;
0.2 is the rational number as it can written in the fraction form as;
0.2 = 2/10
0.2 = 1/5 which is in the p/q form.
For the value of 0.2... repeating is also the rational number as it can be also written in the form of p/q.
0.2... = 0.2 bar is the correct representation.
Therefore, the number 0.2 and 0.2 repeating are the rational numbers.

If I buy a disc that costs $16.30 but there's a 10% discount how much I'm I going to pay
Answer:
$14.67
Step-by-step explanation:
The value of the discount is,
→ (10/100) × 16.30
→ 0.1 × 16.30
→ $1.630
Then the amount he should pay is,
→ 16.30 - 1.630
→ $14.67
Hence, he must pay $14.67.
Answer:
=14.67
Step-by-step explanation:
0.10×16.30=1.63 or
16.30-1.63=14.67 or[tex]\frac{1467}{100}[/tex]

What is the slope of the line? Coordinate grid ranging from negative five to five on the x and y axes. A line passes through points (negative two, one) and (two, negative one). Responses −12 negative fraction 1 over 2 end fraction 2 2 12 1 half −2
The Slope of the line passing through the points (-2,1) and (2,-1) is -1/2 .
The Slope(m) of the line is defined as the change in y coordinate with respect to change in x coordinate ,
The Slope(m) of line passing through the points A(a,b) and B(c,d) is calculated using the formula
m = (d-b)/(c-a)
In the question
it is given that the line passes through the points (-2,1) and (2,-1) .
name the points as A(-2,1) and B(2,-1) .
the values are a=-2 , b=1 , c=2 , d=-1 .
Substituting the values in the formula of Slope we get
m = (-1-1)/(2-(-2))
= -2/(2 + 2)
= -2/4
= -1/2
Therefore , the slope of the line passing through the points (-2,1) and (2,-1) is -1/2 .

The following are the weights of 10 young dogs, in pounds:
7, 5, 11, 8, 14, 19, 16, 15, 13, 27
what proportion of the measurements lie in the interval?
The proportion which falls within the range is 0.9.
Given that data:
x : 7, 5, 11, 8, 14, 19, 16, 15, 13, 27
Mean = Σx / n
Using calculator :
Mean (m) = 13.5
Standard deviation (s) = 6.433
Proportion that lies in mean ± 2s
Lower = Mean - 2s
13.5 - 2(6.433) = 0. 632
Upper = Mean + 2s
13.5 + 2(6.433) = 26.376
Mean ± 2(sd) = (0.632, 26.276)
The only digit from the data which falls outside the defined range = 27
Proportion within interval = 9 / n
Proportion which falls within range = 9/10 = 0.9

150 Minutes
We need to find the Lcm of 25 and 30
Student 1 and Student 12 start from the same point, at same time and in same direction. So they meet again after lcm of the times taken by them individually.
What is LCM?
Least common multiple
To get the LCM we have to factorize the numbers,
25=5*5
30=2*5*3
LCM of 25 and 30 is 5*2*3*5 is 150
Therefore in 15 minutes they meet each other at the starting point
