4.	How to write closure property
Answer» Answer: The Closure Properties Real numbers are closed under addition, subtraction, and multiplication. That means if a and B are real numbers, then a + b is a unique real NUMBER, and a × b is a unique real number. For EXAMPLE, the set of even natural numbers, [2, 4, 6, 8, . . .], is closed with RESPECT to addition because the sum of any two of them is another even natural number, which is also a member of the set.

11.	Lcm of 8, 12 ,10, 20
Answer» Answer: LCM = 120 Solution by Prime FACTORIZATION List all prime factors for each number. Prime Factorization of 8 is: 2 X 2 x 2 => 23 Prime Factorization of 10 is: 2 x 5 => 21 x 51 Prime Factorization of 12 is: 2 x 2 x 3 => 22 x 31 Prime Factorization of 20 is: 2 x 2 x 5 => 22 x 51 For each prime factor, find where it occurs most often as a factor and write it that many times in a new list. The new superset list is 2, 2, 2, 3, 5 Multiply these factors together to find the LCM. LCM = 2 x 2 x 2 x 3 x 5 = 120 In exponential form: LCM = 23 x 31 x 51 = 120 LCM = 120 Therefore, LCM(8, 10, 12, 20) = 120

11.

Lcm of 8, 12 ,10, 20

Answer»

Answer:

LCM = 120

Solution by Prime FACTORIZATION

List all prime factors for each number.

Prime Factorization of 8 is:

2 X 2 x 2 => 23

Prime Factorization of 10 is:

2 x 5 => 21 x 51

Prime Factorization of 12 is:

2 x 2 x 3 => 22 x 31

Prime Factorization of 20 is:

2 x 2 x 5 => 22 x 51

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 2, 2, 3, 5

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 2 x 3 x 5 = 120

In exponential form:

LCM = 23 x 31 x 51 = 120

LCM = 120

Therefore,

LCM(8, 10, 12, 20) = 120

12.	The sum three consecutive natural numbers is 36.what are the number?
Answer» ANSWER: let's take three consecutive numbers be x, x+ 1 , x+ 2 = x + (x +1 ) + (x+2) = 36 3 x + 3 = 36 3X = 36 - 3 x = 33/3 = 11 so the three consecutive numbers are x = 11 x+ 1 = 11 +1 = 12 x + 2 = 11+2 =13

12.

The sum three consecutive natural numbers is 36.what are the number?

Answer»

ANSWER:

let's take three consecutive numbers be x, x+ 1 , x+ 2

= x + (x +1 ) + (x+2) = 36

3 x + 3 = 36

3X = 36 - 3

x = 33/3 = 11

so the three consecutive numbers are

x = 11

x+ 1 = 11 +1 = 12

x + 2 = 11+2 =13

(10) The sum of the numerator and the denominator of a rational number is 19. If 3 is added to the numerator,the rational number becomes 1/3 .What is the rational number?

Answer»

Answer:

5/13

Step-by-step explanation:

ATQ

Let NUMERATOR be x

denominator be y

Then,

x+y=19....(I)

x+3/y=1/3

3(x+3)=y

3x+9=y

3x-y=-9...(ii)

USING ELIMINATION method

x+y=19

3x-y=-9

4x=10

x=2.5..iii

substitute III in i

2.5+y=19

y=19-2.5=6.5

x/y=2.5/6.5

x/y=5/13

A^3+a^2+a+1 factorise

Answer»

Answer:

(a² + 1)(a - 1)

Step-by-step explanation:

GIVEN EQUATION is a³ - a² + a - 1.

'It can be written as',

⇒ (a³ - a²) + (a - 1).

⇒ (a² - a²) + (a - 1)

'Factor out a²', we get

⇒ a²(a - 1) + (a - 1)

⇒ (a² + 1)(a - 1)

Therefore, FACTORIZATION of a³ - a² + a - 1 = (a² + 1)(a - 1).

Hope it is HELPFUL. THANK you!!!!

Answer» ANSWER : 35° and 145° We know, supplementary angles are the angles whose SUM is 180° So, ACCORDING to QUESTION, 2x-5+7x+5=180 = 7x+5x+0=180 9x =180-0 9x=180 x =180/9 x =20 Now,putting the value of x in 2x-5, First supplement angle = 2(20)-5 =40-5= 35° Now, putting the value of x in 7x+5 2nd supplement angle = 7(20)+5=140-5=*135° Therefore, the* two supplementary angles are 35° and 145° HAVE A NICE DAY!

Tivo supplementary angles are (2x - 5)" and (7x + 5)", find the angles please guys tell me

Answer»

ANSWER : 35° and 145°

We know, supplementary angles are the angles whose SUM is 180°

So, ACCORDING to QUESTION,

2x-5+7x+5=180

= 7x+5x+0=180

9x =180-0

9x=180

x =180/9

x =20

Now,putting the value of x in 2x-5,

First supplement angle = 2(20)-5 =40-5= 35°

Now, putting the value of x in 7x+5

2nd supplement angle = 7(20)+5=140-5=135°

Therefore, the two supplementary angles are 35° and 145°

HAVE A NICE DAY!

SP=1596 gain is 12% find CP

Answer»

ANSWER:

$\bold {According \: to \: Question}$

SP = 1596

GAIN% = 12%

CP= ?

_____________________________________

$CP = \frac {100}{(100+Gain\%)} \times SP$

$= > cp = \frac{100}{(100 + 12)} \times 1596$

$= > cp = \frac{100}{112} \times 1596$

$= > cp = \frac{25}{28} \times 1596$

$= > cp = 25 \times 57$

$= > cp = 1425$

_____________________________________

$\tt {Additional \: Information}$

• IMPORTANT FORMULA:-

Gain = (S.P.) - (C.P.)

Loss = (C.P.) - (S.P.)

$gain\% = \frac{gain \times 100}{cp}$

$loss\% = \frac{loss \times 100}{cp}$

$sp = \frac{100 + gain\%}{100} \times cp$

$sp = \frac{100 - loss\%}{100} \times cp$

$cp = \frac{100}{100 + gain\%} \times sp$

$cp = \frac{100}{100 - loss\%} \times sp$
