The best statement about the number 13 is Kaden is incorrect because 13 can be written as a fraction.
What is an Irrational number?An irrational number is a real number that cannot be expressed as a ratio of two integers. In other words, it is a number that cannot be written as a fraction in which the numerator and denominator are both integers, and the denominator is not zero.
Examples of irrational numbers include the square roots of non-perfect squares such as √2, √3, and √5, and numbers like π and e.
Irrational numbers are important in mathematics, as they provide examples of numbers that cannot be expressed exactly, and they can be used to prove certain mathematical theorems.
Given data ,,
Let the number be represented as A
Now , the value of A is
A = 13
And , An irrational number is a number that cannot be expressed as a fraction of two integers.
However, 13 is a rational number because it can be expressed as a fraction, specifically as 13/1
So , Kaden is incorrect because 13 can be written as a fraction.
Hence , the number 13 is not irrational

The area of the triangle below is 1/8 square inches . What is the length of the base ? Express your answer as a fraction in simplest form.
Answer:
1/4
Step-by-step explanation:
(1/8)/(1/2)=(1/8)×2
so, (1/8)×2=2/8, but, wencan simplify it to 1/4.
The length of the base of the right-angle triangle will be 1 / 2 inches.
What is the area of the right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
The area of the triangle below is 1/8 square inches. And the length of the perpendicular will be 1/2 inches.
Then the length of the base will be
A = 1/2 x B x H
1/8 = 1/2 x B x 1/2
1/8 = 1/4 x B
B = 1/2
The length of the base of the right-angle triangle will be 1/2 inches.

Answer:
m=75
percentage= 32
part= 24
whole= 75
Step-by-step explanation:
To get m, you divide 18 by .24(since it's the decimal form of 24%) and you get 75.
The part/whole part I'm not exactly sure about but since it's 24% of 75, I'm guessing the part is 24 and the whole is 75 and that's the entire thing we are working with here.
To get the percentage, we use the 24/75 fraction. We have to get the demonator to 100 but since 75 can't be multiplied by anything to get to 100, we have to simplfy the fraction so the demonator can go into 100. I divided the fraction by 3 since that would get the fraction to 8/25. 25 can go into 100 if we multiply by 4 so that's what you do. The ending fraction would be 32/100 after multiplying the numerator and demonator by 4(8/24). So the percentage would be 32% or 32/100.

Can more than one triangle be drawn with one side length of 4 centimetres and 2 centimetres and an included angle of 50°? Explain.
Answer: No .
Step-by-step explanation:
If we make two triangles with lengths of 4 centimeters and 2 centimeters and an included angle of 50°, then by SAS congruence postulate both triangle will be congruent.
According to the definition of congruence , if two shapes are congruent then they have equal size and shape.
i.e. they look exactly same.
It means only one triangle is possible with the given measurement .
SAS congruence rule : It says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then we can say that these two triangles are congruent.

The hardware store sells red buckets, which hold 4 liters of water, and green buckets, which hold 3 liters. Roxanne bought 7 buckets. Her buckets will hold 24 liters in total. How many of each type of bucket did Roxanne buy?
Answer:
3 red buckets and 4 green buckets
Step-by-step explanation:
You make two equations, one that shows the number of buckets and one that shows the number of liters. We'll make x = the red buckets and y = the green buckets.
x + y = 7 --> This is our first equation, it shows us that x number of red buckets + y number of green buckets equal 7 total (since Roxanne bought 7 buckets).
4x + 3y = 24 --> This is our second equation, it shows us that 4 liters of x number of red buckets + 3 liters of y number of green buckets equals 24 liters total (since her buckets will hold 24 liters in total)
Now that you have identified the two equations, you can solve for variable in equation one, then plug the new equation into equation 2:
x + y = 7 --> y = 7 - x <-- PLUG THIS into the y value of 4x + 3y = 24
4x + 3(7 - x) = 24 <-- SOLVE --> x = 3 <-- NOW WE KNOW THAT THERE ARE 3 RED BUCKETS
plug 3 in for x in the first equation --> 3 + y = 7 --> y = 4
So now we know that there are 3 red buckets, and 4 green buckets.

What is 4x +2 = 9x + 5
This is a challenge whoever gets it right gets brainly why not
What is 4x +2 = 9x + 5
____________________Solution :-Given Information :- 4x + 2 = 9x + 5To Find :-The value of x Calculation :-⇒ 4x + 2 = 9x + 5
Now, subtract 2 from both Left Hand Side and Right Hand Side to eliminate + 2 in Left Hand Side,
⇒ 4x + 2 - 2 = 9x + 5 - 2
⇒ 4x = 9x + 3
Now, subtract 9x from both Left Hand Side and Right Hand Side to eliminate 9x in Right Hand Side,
⇒ 4x - 9x = 9x - 9x + 3
⇒ - 5x = 3
Now, Transpose - 5 to Right Hand Side,
⇒ x = [tex] \sf \frac{ 3}{ - 5} [/tex]
∴ x = [tex] \sf \frac{ 3}{ - 5} [/tex]
____________________Final Answer :-Value of 'x' is [tex] \sf \frac{ 3}{ - 5} [/tex].

PLEASE ANSWER QUICK THIS IS TIMED AND I WILL GIVE BRAINLIEST I PROMISE! The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is studying the change in the amount of money in two accounts, A and B, over time.

Part B: The table below shows the amount g(r), in dollars, of money in account B after r years:
r (number of years) 1 2 3 4

Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer.
Answer:
This was timed and posted awile ago but I don't have the answer either way.
Step-by-step explanation:
Answer:
A) The price of product A is increasing by 3% per year.
(B) The product A recorded a greater percentage change in price over the previous year.
Step-by-step explanation:
(A)
The function representing the price, in dollars, of product A after x years is:
FA(x)=0.69*(1.03)x
The function FA(x)can be written as:
FA(x)=0.69*1+(0.03)x
The function FA(x) is similar to the exponential growth function, y=a(1+r)x .
Here r is the growth rate.
Thus, it can be said that the price of product A is increasing by 3% per year.
(B)
Consider the data of product B for the year 3 and 4.
The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.
Compute the percent price change from year 3 to 4 as follows:
10406.04-10303.01/10303.01*100
which is 0.999%
~1%
The price of product B is increasing by 1% per year.
Thus, the product A recorded a greater percentage change in price over the previous year.
