The study of matter in class 9 typically includes the following topics:
Properties of matter: Students learn about the different physical and chemical properties of matter, such as density, melting point, boiling point, and solubility.
States of matter: Students learn about the three states of matter (solid, liquid, and gas) and how they are different from each other in terms of properties such as shape, volume, and compressibility.
Changes of state: Students learn about how matter can change from one state to another, such as melting, freezing, boiling, and condensation.
Mixtures and solutions: Students learn about the different types of mixtures, such as homogeneous and heterogeneous mixtures, and solutions, such as true solutions, colloidal solutions, and suspensions.
Particles of matter: Students learn about the nature of matter and how matter is made up of tiny particles called atoms and molecules. They also learn about the arrangement of these particles in solids, liquids, and gases.

How to determine the base of the triangleFrom the question, we have the following parameters that can be used in our computation:
Area of the triangle = 80 square millimetres
Height of the triangle = 16 millimetres
Using the above as a guide, we have the following:
The base of the triangle = 2 * Area/Height
Substitute the known values in the above equation, so, we have the following representation
The base of the triangle = 2 * 80/16

in birr 24000is invested at interested rate of 4% compounded you fairly then the amount of money after 10 years in birr?
Answer:
To find the amount of money after 10 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt)
Where:
A = the amount of money after 10 years
P = the initial investment (24000 birr)
r = the interest rate (4%)
n = the number of times the interest is compounded per year
t = the number of years
In this case, since the interest is compounded annually, n = 1.
So,
A = 24000(1 + 0.04)^(1*10)
A = 24000(1.04)^10
A = 24000(1.46) = 24000*1.46 =35,040 birr
So, after 10 years the total amount of money will be 35,040 birr.

There are 5 positions available in the new school. Of the applicant, 12 are men and 8 are women. In how many ways can 3 men and 2 women be chosen if they are equally considered?
There are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting
What is the multiplication principle of countingThe multiplication principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together.
To find the number of ways to choose 3 men from the 12 men, we can use the formula for combination, which is: ⁿCᵣ = n! / (r! (n-r)!).
where n is the total number of men and r is the number of men chosen
so, the number of ways to choose 3 men from the 12 men = ¹²C₃ = 1.
Similarly, we evaluate the number of ways to choose 2 women from the 8 women
as = ⁸C₂ = 14
Now, using the multiplication principle, we can find the total number of ways 3 men and 2 women be chosen if they are equally considered.
220 x 14 = 3080

The number of people etimated to vote in an election wa 7,000. The actual number of people who voted wa 5,600. By what percent did the etimate vary from the actual amount?
75%
1400%
14%
25%
The estimate of the no. of people to vote varies by 25% from the actual no. of voters turned out.
Finding the per cent variation of estimated votes from the actual turnout
The no. of people estimated to vote in the election = 7000
The actual no. of people who voted = 5600
A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
∴ The per cent by which the estimate vary from the actual turnout is given by,
= [{7000 – 5600}/ {5600}]×100
= [1400/5600]×100
= 0.25×100
= 25%
Therefore, the 25% of the estimate vary from the actual amount.

What is the complete factor of x² +5x +6?.
The complete factor of the polynomial x² + 5x +6 is (x + 3)(x + 2).
You can factor it by using the factorization methods such as
Factor by grouping
Factor by grouping and completing the square
Factoring by using difference of squares
Factoring by using sum and difference of cubes
For example, you can factor it by using the difference of squares method:
x² + 5x +6 = (x² + 6x + 9) - (x +3)
We know x² + 6x + 9 = (x + 3)², So
x² + 5x +6 = (x + 3)² - (x + 3)
Taking (x + 3) common
x² + 5x +6 = (x + 3)(x + 3 - 1)
x² + 5x +6 = (x + 3)(x + 2)
So (x + 3)(x + 2) is complete factor.

The following observations are arranged in ascending order.
The median of the
data is 32. Find the value of x.
13, x, 26, 3x+2, 39, 41, 50
Answer:7.5
Step-by-step explanation:
The median is the middle value of a set of observations when they are arranged in ascending order. Since the observations are already arranged in ascending order and there are 7 observations, the median will be the fourth value.
Given that the median is 32, we know that the fourth value is 32. The observations are:
13, x, 26, 32, 39, 41, 50
So x + 3x + 2 = 32
4x + 2 = 32
4x = 30
x = 7.5
The value of x is 7.5.

What are the 3 conditions a square root radical must meet to be in simplified form?.
The three conditions must be satisfied for a square to be in its simplest form, that is, first, No radicands other than 1 have perfect square factors. Secondly, there isn't a fraction in any radicand and finally, the fraction's denominator has no radicals.
A square root can be reduced to a simple form by first factoring it into primes, then finding the radical's index, and finally moving the group of numbers either inside or outside the radical.
The expressions both inside and outside the radical can then be made simpler by adding up all the numbers inside the radical.

Let y represent how many large mugs he purchases.
We are aware that x+y=15 (the total number of mugs he buys)

Is an absolute value function increasing or decreasing?.
The absolute value function is increasing on [0,∞) and decreasing on (−∞,0].
There are a few ways to describe what is meant by the absolute value |x| of a real number x. You may have been taught that |x| is the distance from the real number x to the 0 on the number. So, for example, |5| = 5 and | − 5| = 5, since each is 5 units from 0 on the number line.
Another way to define absolute value is by the equation |x| = √x2. Using this definition, we have
|5| = √(5)² = √25 = 5 and | − 5| = √(−5)² = √25 = 5. The long and short of both of these procedures is that |x| takes negative real numbers and assigns them to their positive counterparts while it leaves positive numbers alone.

The value for 1 mol Na is 23 gm/mol and 1 mol Br_2 is 160 gm/mol, so the volume will be different.
What is mole?
The mole idea is a useful way to indicate how much of a substance there is. Any measurement can be divided into two components: the magnitude in numbers and the units in which the magnitude is expressed.
Even one gram of a pure element is known to have an enormous number of atoms when working with particles at the atomic (or molecular) level. The mole idea is frequently applied in this situation. The unit of measurement that receives the most attention is the "mole," which is a count of a sizable number of particles.
The molar mass for 1 mole of solid sodium (Na) = 23 gm/mol
The molar mass for 1 mole of liquid bromine (Br) = 79.90 gm/mol
The molar mass for 1 mole of liquid bromine (Br_2) = 160 gm/mol
