๐Answer to Question #1๏ธโฃ๐
โ ๏ธA triangle has angles in the ratio 2:3:5. What are the measures of the angles?
๐To solve this question, we can set up an equation using the given ratio.
And, we know that the sum of the three angles of a triangle is 180ยฐ.
If we name the angles by the symbols: a, b and c. Then,
a + b + c = 180ยฐ
Given that
a/b=2/3 and b/c=3/5, we get
a= 2/3b and b= 3/5c, so,
a=2/3(3/5c)=2/5c.
Now, both a and b are expressed interms of c. So,
In the equation
a + b + c = 180ยฐ
Replace a and b to get,
2/5c + 3/5c + c = 180ยฐ
Which is one equation in one variable.
multiply both sides by 5 to get rid of the denominator :
2c + 3c + 5c = 5ร180
10c =900
c = 90
Then, b= 3/5c
=> b = 3/5(90)
= 3ร(90/5) = 3ร18 = 54,
and
a = 2/3b = 2/3(54)= 36.
โ Check: 36 + 54 + 90 = 180.
๐OR๐
Let x be the common multiplier for the ratio.
The measures of the angles can be represented as 2x, 3x, and 5x.
Since the sum of the angles in a triangle is 180 degrees, we can set up the equation:
2x + 3x + 5x = 180
Simplifying the equation:
10x = 180
Dividing both sides by 10:
x = 18
Now we can find the measures of the angles:
2x = 2 ร 18 = 36 degrees
3x = 3 ร 18 = 54 degrees
5x = 5 ร 18 = 90 degrees
Therefore, the measures of the angles in the triangle are 36 degrees, 54 degrees, and 90 degrees.

Question 2:
To solve this question, we can use the formula for distance, which is speed multiplied by time.
Given:
Speed = 60 miles per hour
Time = 3.5 hours
Using the formula, we can calculate the distance traveled:
Distance = Speed * Time
Distance = 60 miles/hour * 3.5 hours
Distance = 210 miles
Therefore, the car will travel a distance of 210 miles in 3.5 hours.
Question 3:
To solve this equation, we need to isolate the variable x.
Given equation:
3x + 7 = 22
Subtracting 7 from both sides of the equation:
3x + 7 - 7 = 22 - 7
3x = 15
Dividing both sides of the equation by 3:
3x/3 = 15/3
x = 5
Therefore, the solution to the equation is x = 5.
Question 4:
To find the perimeter of a rectangle, we need to add up all four sides.
Given:
Length = 12 meters
Width = 8 meters
The formula for the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
Plugging in the given values:
Perimeter = 2 * (12 meters + 8 meters)
Perimeter = 2 * (20 meters)
Perimeter = 40 meters
Therefore, the perimeter of the garden is 40 meters.
Question 5:
To find the area of a circle, we need to use the formula:
Area = ฯ * radius^2
Given:
Radius = 5 cm
Plugging in the given value and using the approximation ฯ โ 3.14:
Area = 3.14 * (5 cm)^2
Area = 3.14 * (25 cm^2)
Area = 78.5 cm^2
Therefore, the area of the circle is 78.5 square centimeters.
To solve this question, we can use the formula for distance, which is speed multiplied by time.
Given:
Speed = 60 miles per hour
Time = 3.5 hours
Using the formula, we can calculate the distance traveled:
Distance = Speed * Time
Distance = 60 miles/hour * 3.5 hours
Distance = 210 miles
Therefore, the car will travel a distance of 210 miles in 3.5 hours.
Question 3:
To solve this equation, we need to isolate the variable x.
Given equation:
3x + 7 = 22
Subtracting 7 from both sides of the equation:
3x + 7 - 7 = 22 - 7
3x = 15
Dividing both sides of the equation by 3:
3x/3 = 15/3
x = 5
Therefore, the solution to the equation is x = 5.
Question 4:
To find the perimeter of a rectangle, we need to add up all four sides.
Given:
Length = 12 meters
Width = 8 meters
The formula for the perimeter of a rectangle is:
Perimeter = 2 * (Length + Width)
Plugging in the given values:
Perimeter = 2 * (12 meters + 8 meters)
Perimeter = 2 * (20 meters)
Perimeter = 40 meters
Therefore, the perimeter of the garden is 40 meters.
Question 5:
To find the area of a circle, we need to use the formula:
Area = ฯ * radius^2
Given:
Radius = 5 cm
Plugging in the given value and using the approximation ฯ โ 3.14:
Area = 3.14 * (5 cm)^2
Area = 3.14 * (25 cm^2)
Area = 78.5 cm^2
Therefore, the area of the circle is 78.5 square centimeters.

๐Types Of Substances
๐The whole universe is made up of one or the other kind of matter. These matters are nothing but something that has mass and occupies space.
๐Although everything around us is a matter, this matter has a broad classification as the things around us are not all the same. The matter is classified into:
๐Pure substances
๐Mixtures
Pure Substances
๐The term is a very common one related to our daily lives.
๐The matter that is made up of only one kind of particle or one kind of atom/molecule is defined as a pure substance. Also, the term itself explains the same where pure means only one kind.
๐The common exams of pure substances are gold, silver, iron, etc.
PURE SUBSTANCES
๐The pure substances are subdivided into two types on the basis of chemical compositions:
๐Elements
๐Elements is a subdivision of the pure substance which is made of a single kind of atom and can not be further broken down into a much simpler substance.
๐These elements are such that on applying either physical or chemical processes, none can break it into a more simple substance as in the case of a gold piece which if broken into pieces still remains the same gold piece.
๐The elements are further classify in to:
๐Metals: Metals are elements which easily lose electrons. For example: aluminium, iron etc. They are lustrous, good conductors, malleable, ductile and sonorous.
๐Non- Metals: Non metals are elements which easily gain electrons to become stable. For example, oxygen, chlorine. These non metals are non-lustrous, easily breakable, have low density etc.
๐Metalloids : the elements which possess the properties of both metals as well as non metals are called metalloids. For example, silicon, boron etc. they are basically called amphoteric in nature.
๐Noble gases: noble gases are those elements which do not react and have completely filled the outermost shell. For example: neon, argon etc.
๐Compounds
A compound is a type of pure substance which is formed chemically by the combination of two or more substances but in a fixed proportion.
Compounds are also further divided into:
๐Organic : organic substances are those substances which are formed by combination of carbon-hydrogen bonds.
๐Non-Organic: non organic compounds are the one which do not have the carbon-hydrogen bonding.
๐Mixtures are the type of matter which form by mixing more than one kind of atom, particle, or substance. Types of mixtures
๐Homogeneous: Homogeneous mixtures are the mixtures in which the different substances are mixed together but uniformly.
๐Heterogeneous: heterogeneous mixtures are those mixtures in which the different substances are mixed but the composition is not uniform throughout.

๐The whole universe is made up of one or the other kind of matter. These matters are nothing but something that has mass and occupies space.
๐Although everything around us is a matter, this matter has a broad classification as the things around us are not all the same. The matter is classified into:
๐Pure substances
๐Mixtures
Pure Substances
๐The term is a very common one related to our daily lives.
๐The matter that is made up of only one kind of particle or one kind of atom/molecule is defined as a pure substance. Also, the term itself explains the same where pure means only one kind.
๐The common exams of pure substances are gold, silver, iron, etc.
PURE SUBSTANCES
๐The pure substances are subdivided into two types on the basis of chemical compositions:
๐Elements
๐Elements is a subdivision of the pure substance which is made of a single kind of atom and can not be further broken down into a much simpler substance.
๐These elements are such that on applying either physical or chemical processes, none can break it into a more simple substance as in the case of a gold piece which if broken into pieces still remains the same gold piece.
๐The elements are further classify in to:
๐Metals: Metals are elements which easily lose electrons. For example: aluminium, iron etc. They are lustrous, good conductors, malleable, ductile and sonorous.
๐Non- Metals: Non metals are elements which easily gain electrons to become stable. For example, oxygen, chlorine. These non metals are non-lustrous, easily breakable, have low density etc.
๐Metalloids : the elements which possess the properties of both metals as well as non metals are called metalloids. For example, silicon, boron etc. they are basically called amphoteric in nature.
๐Noble gases: noble gases are those elements which do not react and have completely filled the outermost shell. For example: neon, argon etc.
