Hey FRIEND...
Here is your answer

27x3 + y3 + z3 - 9xyz
              = (3x)3 + y3 + z3 - 3 × (3x) × y × z  
              = [3x + y + z ][(3x)2 + y2 + Z2 - (3x) × y − y × z  − z(3x)] [Since  (a + b + c )(a2 + y2 + z2 - ab−bc−ca)]
              = [3x + y + z ][9x2 + y2 + z2 - 3xy − yz  − 3zx

I hope it will help you MATE

2x+3x = 180° (linear pair)
5X = 180°
x = 180/5
x = 36°

2x = 2×36 = 72°

2x = y+30° ( Vertically Opposite Angles)
72 = y+30°
72-30 = y
42 = y
y = 42°
Answer is E

Answer:

48

Let us find the FACTORS of 144 and 96. = 48. Therefore, the greatest number which DIVIDES 149 and 101 leaving a REMAINDER of 5 is 48.

I hope It helped you lot so follow me please

Sum of first 53 numbers is GIVEN by 53(53+1)/2=53×54/2=53×27=1431
cube root of 1431 NEAR to 11

Principal =RS 9000
time = 2.4 years
rate of INTREST= 10%
ptr/100
9000×2.4×10/100
=2160 hope U understand my dost

Solution:

_______

AVERAGE age = 10.5

Sum of total age of the 50 students = 50 X 10.5 = 525

After including the teacher

total strength = 51

new average = 10.5 + 0.5 = 11

sum of total age of all 51 = 51 x 11 = 561

the age of teacher = 561 - 525 = 36

So, the age of the teacher is 36 years

Note: I have MADE a correction in the given question by taking NUMERAL 5 as 0.5.

Pollution contributes to the harmful environment that results in adverse effect on living beings. It is one of the major concern areas for the whole world. It is a global issue involving the United Nations, governments, voluntary institutions and the media.

Students need to be made fully aware of the adverse effects of rising pollution. Also, being the future generation, they can play a vital role in controlling pollution if they are familiar with this threat to the survival of mankind.

Here we are providing you some useful articles on pollution under various categories according to varying words limits. You can choose any of them according to your need:

 

Pollution Articles

Article on Pollution 1 (300 words)

Anything added into the environment that results in producing harmful or poisonous effect on living things is called pollution. Pollution is the process that makes nature’s resources such as land, water, air or other parts of the environment unsafe or unsuitable to use. Pollution can be of many types:  soil, air, water, thermal, radioactive, noise, and light. The toxins released are inhaled by each one of us while we breathe.

Pollution and its Causes

Inhaling poisonous air is as hazardous as smoking. It is not only the humans who are affected from this polluted environment but also the animals. Air is filled with highly toxic gases. These dangerous gases in environment are released by the power industries that burn fossil fuels, industries that dispose wastes in the water, farmers using pesticides, high usage of artificial lights and loud sounds, etc. Each of these leads to generation of the life threatening cause – pollution.

Any use of natural resources at a rate higher than the nature’s capacity to restore itself can result in pollution of air, water, and land. Other than HUMAN activities, there are a few periodic natural cycles that also result in release of dangerous stuff. Natural activities other than the human activities like volcanic eruption, dust wildfires, etc also result in creation of pollution.

Globalization is another major cause of pollution. Globalization has become an effective facilitator of environmental degradation.

Conclusion

Every individual owns certain responsibility of maintaining few points such as not throwing garbage all around, growing trees, using public TRANSPORT instead of their own, etc. We must shun excessive consumption and avoid careless and deliberate disposal of post-consumption waste resources which could otherwise be recycled and would led to pollution control.

Pollution cannot be reduced or controlled if a SENSE of responsibility towards our Mother Earth is not felt by all concerned.

Article on Pollution 2 (500 words)

Pollution is a process of making the environment dirty, unhealthy and unsuitable for humans and animals to live. It is caused due to the release of both tangible and intangible contaminants. These can be released naturally or by humans themselves accidentally or deliberately.

More than 200 million people are affected due to toxic pollutants. Due to pollution, there are few countries that have faced defected child birth and increase in mortality rate. Humans are regularly exposed to pollution when they inhale toxic air inside them.

Pollution can be controlled, if not eliminated. Efforts such as promoting green environment, proper disposal of waste, etc are simple steps that lead to GREAT emphasis on maintaining the order of environment.

Preventive measures:

Plant trees/cultivate garden to curb polluted air and release more oxygen.Switch off electricity-based equipments when not in use: lights, fans, machines, etc.Make high use of natural energy than ELECTRIC energy: dry the clothes naturally.Use recyclable products, wherever possible.Avoid plastic bags and use paper bags.Avoid wastage of paper and use both the sides.Restrict usage of hazardous chemicals.

A^2 + a -6 =0

Let son's age today is x

two YEARS ago son's age will be x-2

two years ago father's age will be 5(x-2)

two years later son's age will be x+2

two years later father's age will be 3x+8+2

now, x-2 + 5(x-2) = x+2 + 3x+8+2

x-2 + 5x - 10 = 4x + 12

6x -12 = 4x +12

2x = 24

x = 12

son's present age is 12

fathers present age is 5(x-2) + 2 = 5 (12-2) +2 = 52

15 and 10

15 sq=225

10 sq=100

225-100=125

We KNOW that n (A UNION B)=n (A)
+n (B)-n (A INTERSECT B)
=20+30-10
=50-10
=40
So n (A union B) is 40

Let the hypotenuse be X. Using the pythagorean theorem:

(x/2)^2 + 3 = x^2

x^2+12 = 4X^2

12 = 3x^2

x^2 = 4

x = 2

so the side length is 2, and the perimeter is 6

4x + 5y = 23

xy = 6, => y = 6 / X

Substituting value of y = 6 / x in the first equation we get,

4x + 5 ( 6 / x ) = 23

4x + 30 / x = 23

Taking LCM we get,

4x² + 30 / x = 23

4x² + 30 = 23 x

=> 4x² - 23x + 30 = 0

=> 4x - 15x - 8x + 30 = 0

=> x ( 4x - 15 ) - 2 ( 4x - 15 ) = 0

=> ( 4x - 15 ) ( x - 2 ) = 0

=> x = 15 / 4 ; 2

Taking X = 2 we get y = 6 / 2 = 3

So value of 16x² + 25y² is :

16 ( 2 )² + 25 ( 3 )²

16 * 4 + 25 * 9

A SET which has all NATURAL NUMBERS can be the UNIVERSAL set for these.

This is a QUESTION of permutations.

n = the number of objects and in this CASE we have 5 team members.

They are picked 1 at a time :

Formula :

n! / (n - R)!

5! / (5 - 1)!

5! / 4!

(5 x 4!) / 4!

Let the numbers be a and b

According to question,

a + b = 137 ----------(1)

a - b = 43 -----------(2)

On ADDING EQUATION 1 and 2, we get

2a = 180

=> a = 90

b = 137 - 90 =47

First number = 90

Second number = 47
