Answer:
0.43ᵣ = 0.1 + 0.33ᵣ = 1/10 + 1/3 = 3/30 + 10/30 = 13/30
The expression 0.43333... is equivalent to the fraction number 13/30. And it is proved below.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
x = 0.43333......
Multiply the equation by 10 on both sides, then we have
10x = 10 × 0.43333......
10x = 4.33333...... ...1
Multiply the equation by 100 on both sides, then we have
100x = 100 × 0.43333......
100x = 43.33333...... ...2
Subtract equation 1 from equation 2, then we have
100x - 10x = 43.3333.... - 4.3333.....
90x = 39
x = 39 / 90
x = 13 / 30
The expression 0.43333... is equivalent to the fraction number 13/30. And it is proved below.

O 32 ft
Answer:
[tex]16\sqrt{2}[/tex]
Step-by-step explanation:
The given triangle shown is a 45-45-90. We can use this picture attached to figure out BC.
n in this case is 16ft
Based on the picture, we can get BC's length, which is n[tex]\sqrt{2}[/tex]
BC = [tex]16\sqrt{2}[/tex]

Which statement explains how you could use coordinate geometry to prove that quadrilateral ABCD is a rectangle
Answer:
prove that opposite sides are congruent and parallel
Step-by-step explanation:
i took the testtttttt
The statement which explains is Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals, the correct option is D.
We are given that;
The quadrilateral ABCD
Now,
A rectangle is a quadrilateral with four right angles, which means that the slopes of consecutive sides are negative inverses of each other.
For example, if the slope of AB is m, then the slope of BC is -1/m.
Also, a rectangle has opposite sides that are equal in length,
which means that the distance between A and B is the same as the distance between C and D, and the distance between B and C is the same as the distance between A and D.
Therefore, by quadrilateral the answer will be prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals.

The coordinates of point T are (0,5). The midpoint of ST is (2,-2). Find the coordinates of point S.
The other endpoint is
(Type an ordered pair.)
Answer:
[tex]S = (4,-9)[/tex]
Step-by-step explanation:
Given
[tex]T = (0,5)[/tex]
[tex]Midpoint = (2,-2)[/tex]
Required
Find S
Midpoint is calculated as:
[tex]Midpoint = 0.5(x_1 + x_2,y_1+y_2)[/tex]
So, we have:
[tex](2,-2)= 0.5(0+ x_2,5+y_2)[/tex]
Where x2 and y2 are the coordinates of S
Multiply through by 2
[tex]2 * (2,-2)= 2 * 0.5(0+ x_2,5+y_2)[/tex]
[tex](4,-4)= (0+ x_2,5+y_2)[/tex]
[tex](4,-4)= (x_2,5+y_2)[/tex]
By comparison:
[tex]x_2 = 4[/tex]
[tex]5 + y_2 = -4[/tex]
[tex]y_2 = -4-5[/tex]
[tex]y_2 = -9[/tex]
So:
[tex]S = (4,-9)[/tex]

Suppose we want to choose 5 objects, without replacement, from 9 distinct objects. (a) How many ways can this be done, if the order of the choices is not taken into consideration? (b) How many ways can this be done, if the order of the choices is taken into consideration?
The number of ways if the order of the choices is not taken into consideration and taken into consideration will be 126 and 15,120, respectively.
What are permutation and combination?A permutation is an act of correctly arranging things or pieces. Combinations are a method of taking stuff or pieces from an assortment of items or sets in which the order of the items is irrelevant.
Suppose we want to choose 5 objects, without replacement, from 9 distinct objects.
Then the number of ways that this can be done, if the order of the choices is not taken into consideration will be given as,
⁹C₅ = 9! / [(9 - 5)! x 5!]
⁹C₅ = (9 x 8 x 7 x 6 x 5!) / (4 x 3 x 2 x 1 x 5!)
⁹C₅ = 126
Then the number of ways this can be done, if the order of the choices is taken into consideration will be given as,
⁹P₅ = 9! / [(9 - 5)!
⁹P₅ = (9 x 8 x 7 x 6 x 5 x 4!) / 4!
⁹P₅ = 15,120
The number of ways if the order of the choices is not taken into consideration and taken into consideration will be 126 and 15,120, respectively.

Mark me brainiest if it had helped youat a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of levi jeans with an original price of x?
Given:
Discount = 40%
Sales tax = 7%
To find:
The total cost of levi jeans with an original price of x.
Solution:
Let x be the original price of the jeans. Then the price after 40% discount is
[tex]Price=x-40\%\text{ of }x[/tex]
[tex]Price=x-\dfrac{40}{100}x[/tex]
[tex]Price=x-0.4x[/tex]
[tex]Price=0.6x[/tex]
The price after 7% of sales tax.
[tex]Price=0.6x+7\%\text{ of }0.6x[/tex]
[tex]Price=0.6x+\dfrac{7}{100}\times 0.6x[/tex]
[tex]Price=0.6x+0.042x[/tex]
[tex]Price=0.642x[/tex]
Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.
