Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π as "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational."
What is rational number?If p and q are integers and q is not equal to 0, then the number is in the form of p/q and is said to be rational. Among the rational number examples are 1/3, 2/4, 1/5, 9/3, and so forth. P/Q is the format for rational numbers, where p and q are open-ended integers and q 0. Thus, natural numbers, whole numbers, integers, fractions of integers, and decimals are all examples of rational numbers (terminating decimals and recurring decimals).
What is irrational number?Any real number that cannot be expressed as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number. For instance, the square root of 2 cannot be expressed as an integer or a fraction. A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational. Example: The numbers 2, 3, 5, 11, 21, and (Pi) are all illogical.
Here,
Rational number=1/4, 2/3, √4
Irrational number=√8, √90, π/2, π
As "Any whole number, fraction, or decimal that ends or repeats is a rational number. Any number that cannot be divided into a fraction and thus does not meet the definition of a rational number is considered to be irrational." so Rational number will be 1/4, 2/3, √4 and Irrational number will be √8, √90, π/2, π.

I have no idea how to solve this problem, could someone help me?△ABC∼△XYZ. Find the values of x and b (side lengths).
The symbol ∼ denotes similarity, that is, the triangles ABC and XYZ are similar. When two triangles are similar, they have the same shape but not necessarily the same size and their corresponding angles are the same. In turn, the corresponding sides of two corresponding triangles are in the same ratio. Graphically,
[tex]\frac{a}{a^{\prime}}=\frac{b}{b^{\prime}}=\frac{c}{c^{\prime}}[/tex]So to find x in the small triangle, you have
[tex]\begin{gathered} \frac{15}{10}=\frac{9}{x} \\ \text{ Multiply by x on both sides of the equation} \\ \frac{15}{10}\cdot x=\frac{9}{x}\cdot x \\ \frac{15}{10}x=9 \\ \text{ Multiply by }\frac{10}{15}\text{ on both sides of the equation} \\ \frac{10}{15}\cdot\frac{15}{10}x=9\cdot\frac{10}{15} \\ x=6 \end{gathered}[/tex]Finally, to find b in the large triangle, you have

Answer:
Zavier had 37 books, and Maria had 33 books
Step-by-step explanation:
You take 70 and divide it by 2 (cause you are only dividing the books up to maria and Zaviar); this will give you 35 books to each person EXCEPT Zavier has two more books to his pile, so you subtract two books from Marie and add it to Zaviers!
Evaluate inverse functions The graph of y= h(x) is a line segment joining the points (-7,-5) and (-1,-2) Drag the endpoints of the segment below to graph y=h^-1(x)
When we have an inverse function, the domain and range are switched.
All x-coordinates become y-coordinates and vice-versa.
So, if the point (-7, -5) is a solution of h(x), the point (-5, -7) is a solution of h^-1(x)
If the point (-1, -2) is a solution of h(x), the point (-2, -1) is a solution of h^-1(x).
Therefore, the endpoints of the segment that represents the inverse function are the points (-5, -7) and (-2, -1).

The area of a rectangle is the product of its length and breadth. The maximum area enclosed by the fence is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.
What is a rectangle?A rectangle is a kind of parallelogram that has equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
The dimensions of the given rectangle is (650 - 2x) and x.
Then, the area of the given rectangle is A(x) = x(650 - 2x)
In order to find the maximum area enclosed take the derivative of A(x) and equate it to zero as follows,
(660 - 2x) - 2x = 0
=> 4x = 660
=> x = 660 / 4
=> x = 115
Now, the maximum area is the value of A(x) at x = 115 as below,
= 115 × (650 - 2×115)
= 115 × 320
= 36800
The dimensions for the maximum area are 115 and (650 - 2 × 115) = 320.
Hence, the largest area enclosed is 36800 square meter and the dimensions of the enclosed area are 115 meter and 320 meter. The width is given as 115 meter.

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.
Answer:
perimeter is 7.5 units
Step-by-step explanation:
the sides of the regular polygon are the same length , then
5x - 6 = 3)x - 1)
5x - 6 = 3x - 3 ( subtract 3x from both sides )
2x - 6 = - 3 ( add 6 to both sides )
2x = 3 ( divide both sides by 2 )
x = 3 ÷ 2 = 1.5
then length of one side is
5x - 6 = 5(1.5) - 6 = 7.5 - 6 = 1.5 units
then perimeter = 5 × 1.5 = 7.5 units

We can find the percentage of increase in the number of Magikarps that Jose captured in the lake by taking the initial number of them and subtracting it from the number that he had by the end of the day, like this:
16 - 8 = 8
Now, we just have to divide 8 by 16 and then multiply by 100, like this:

Richard says that the rule (x,y)--> (0.2x,y) describes a horizontal stretch because only the x-coordinates are affected by the real. Is Richard correct? Why or why not?
Although it is true that only the x-axis is affected, that is, on the horizontal, when multiplying by a number less than 1, there would not be a stretch but a narrowing.
That is, the horizontal part would be smaller, which contradicts what Richard says.

You flip a coin and then spin this spinner. a) Determine whether these events are Independent or Dependent. Write I on D b) Find the probability that the coin lands tails-up and the spinner Yands on a I Write as a reduced fraction (numerator/denominator). 1
SOLUTION
Dependent events influence the probability of other events or their probability of occurring is affected by other events. Independent events do not affect one another and do not increase or decrease the probability of another event happening.
PART A
Since the flip of a coin would not affect the spin of the spinner, therefore these events are independent events.
The answer is 'I'
PART B
To find the probability that the coin lands tails-up and the spinner lands on 1, we would need to find the probability of getting a tail, then we find the probability of getting a 1
Therefore,
[tex]\text{Probaility}=\frac{no\text{ of favourable outcomes}}{\text{Total possible outcomes}}[/tex]When we flip a coin, the favourable outcome for a tail is 1 since a tail can only occur once in one flip. The total possible outcomes are 2, since we can have either a tail or head occurring in one flip.
Then,
[tex]Pr(\text{Tail)}=\frac{1}{2}[/tex]When we spin the spinner, the favourable outcome for one is 1, since we have only one slot for one on the spinner. The total possible outcome is 4 since we have 4 different number
slots on the spinner.
Then,
[tex]Pr(1)=\frac{1}{4}[/tex]To get the probability of getting a tail, then we find the probability of getting a 1 we multiply the probability of getting a one on the spinner and a tail on the flip.

What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
A toy rocket is shot upward up high from a take-off platform 3 feet over the ground with an underlying speed of 48 feet each second. The level h, in feet, of the rocket over the ground at t seconds after send-off is given by the capability h(t) = - 16t² + 48t + 3.
Differentiate the function and put it equal to zero.
h'(t) = 0
-32t + 48 = 0
32t = 48
t = 1.5 seconds
Then the maximum height is given as,
h(1.5) = - 16(1.5)² + 48(1.5) + 3
h(1.5) = 39 feet
The rocket reaches its maximum height at 1.5 seconds after launch will be 39 feet.

What is solving an equation?
Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution.
Consider, the given equation[tex]\frac{2}{3}x - 1=9-\frac{1}{6}x[/tex]
Add 1 on both sides,
[tex]\frac{2}{3}x -1+1 = 9-\frac{1}{6}x+1\\ \frac{2}{3}x=10-\frac{1}{6}x[/tex]
Add 1/6(x) to both sides,
[tex]\frac{2}{3}x + \frac{1}{6}x = 10 - \frac{1}{6}x+\frac{1}{6}x\\ \frac{5}{6}x = 10[/tex]

Given:
The graph shows the prices of the current year for the number of bushels.
And the table shows the prices of the previous year.
Part A: We will find the rate of change of bushels of corn in the current year.
As the graph shows a line, so, the rate of change will be the slope of the line
We will find the slope using two points.
As shown the line passes through the points (0,0) and (3,24)
So, the slope will be as follows:
[tex]slope=\frac{24-0}{3-0}=\frac{24}{3}=8[/tex]So, the rate of change = $8 per Bushel.
Part B: How many dollars more in the price of a bushel of corn in the current year than the previous year.
From the table: the price of the previous year = 21/3 = $7
And form the graph, the price of the current year = $8
So, the differnce = 8 - 7 = $1
So, the answer will be:
$1 more is the price of the current year than the price of the previous year.
