ANSWER:

If we SUBTRACT 0 from 5 then it will be 5 only and EVEN if we ADD 0 to 5 it will be five only so the answer is 5

Answer:

Perimeter of a square shaped floor is = 80m

→ 4a=80

→ a=20m

Thus,

Length (a) = 20 m

Breadth (a) = 20 m

Height (h)= 9.5 m

COST :

Area of FOUR walls and top

2(L+b)h+a²   or   2(a+a)h+a²

→ 2(20+20)9.5+20²

→ 2(40)9.5+400

→ 80 x 9.5 +400

→ 760+400

→ 1160m²

Cost of PAINTING 1 m² = Rs. 14

Therefore,

Cost of painting 1160m² = Rs. {1160×14} = Rs. 16240

VOLUME :

Volume of room = l x b x h     or     a x a x h

= 20 x 20 x 9.5

= 380m³

Hence,

Cost of Painting = Rs. 16240

Volume of room = 380m³

Answer:

Step-by-step explanation:

i) 252 = 2 x 2 x 3 x 3 x 7

Here, prime factor 7 has no pair. Therefore 252 MUST be DIVIDED by 7 to MAKE it a perfect square.

\therefore252\div7=36∴252÷7=36

And \sqrt{36}=2\times3=6  

36

​  

=2×3=6(ii) 2925 = 3 x 3 x 5 x 5 x 13

Here, prime factor 13 has no pair. Therefore 2925 must be divided by 13 to make it a perfect square.

\therefore2925\div13=225∴2925÷13=225

And \sqrt{225}=3\times5=15  

225

​  

=3×5=15

(iii) 396 = 2 x 2 x 3 x 3 x 11

Here, prime factor 11 has no pair. Therefore 396 must be divided by 11 to make it a perfect square.

\therefore396\div11=36∴396÷11=36

And \sqrt{36}=2\times3=6  

36

​  

=2×3=6

) 2645 = 5 x 23 x 23

Here, prime factor 5 has no pair. Therefore 2645 must be divided by 5 to make it a perfect square.

\therefore2645\div5=529∴2645÷5=529

And \sqrt{529}=23  

529

​  

=23

v) 2800 = 2 x 2 x 2 x 2 x 5 x 5 x 7

Here, prime factor 7 has no pair. Therefore 2800 must be divided by 7 to make it a perfect square.

\therefore2800\div7=400∴2800÷7=400

And \sqrt{400}=2\times2\times5=20  

400

​  

=2×2×5=20

vi) 1620 = 2 x 2 x 3 x 3 x 3 x 3 x 5

Here, prime factor 5 has no pair. Therefore 1620 must be divided by 5 to make it a perfect square.

\therefore1620\div5=324∴1620÷5=324

And \sqrt{324}=2\times3\times3=18  

324

Answer:

1.5 hours

Step-by-step explanation:

TIME taken by each pipe to FILL TANK separately:

A = 8

B = 16

C = 12

D = 16

work done in 1 hr :

by A = 1/8

by B = 1/16

by C = 1/12

by D = 1/16

work done in 1 hr when all pipes are opened :

1/8 + 1/16 + 1/12 + 1/16

= 1/3

time taken for tank to be full when all pipes are open:

3 hrs

time taken to fill HALF of the tank : 3/2 = 1.5 hrs

so the answer is 1pm

Answer:

a = -6.5

b = -26

Step-by-step explanation:

9x²+bx+16              X-2 is factor so x = 2

9(2)² + b(2) + 16 = 0

9(4) + 2B + 16 = 0

36 + 16 + 2b = 0

52 + 2b = 0

2b = - 52

b = -52/2

b = - 26

b = 4a

-26 = 4a

-26/4\\ = a

a = - 6.5

Take another point E in BC , such that AE is perpendicular to BC.

Since it's a perpendicular LINE in an equilateral ∆ AE divides the∆ into TWO equal RIGHT angle ∆s ABE and ∆ AEC

and hence, BE= EC

BC= BE+BE= 2BE

BE= 1/2 BC

And BE= BD+ED

1/2BC=1/3BC+ED

ED= BC/2 - BC/3= BC/6

Also, we KNOW that AB=BC=CA (sides of equilateral ∆)

let x represent all these sides,

In ∆ ABE

x²= BE²+EA²

EA²= x²-BE²

Now in ∆ ADE

AD²=ED²+AE²

AD²= (x/6)²+(x²-(x/2)²

AD²=x²/36+(x²-x²/4)

AD²= x²/36+[(4x²-x²)/4]

AD²= x²/36+3x²/4

AD²= (x²+27x²)/36

36AD²= 28x²

36AD²= 28AB²

9AD²=7AB²

now MULTIPLYING both with 3

27AD²=21AB²

hope this will HELP you

Answer:

For the two positive INTEGER, "a" and "b", we have

H.C.F. (a,b) x L.C.M. (a,b) = a x b   ...( i )

Here,

(a) 16, 24

LCM (16, 24) = 48

HCF (16, 24) = 8

put the values in eq. ( i )

48 x 8 = 16 x 24

384 = 384

(b) 30, 45

LCM (30, 45) = 90

HCF (30, 45) = 15

put the values in eq. ( i )

90 x 15 = 30 x 45

1350 = 1350

Hence, both question are proved.

Answer:

Firstly FACTORISE the given polynomial and then put each factor equal to zero to FIND required zeroes and then for verification show that

Sum of zeroes = - COEFFICIENT of x/coefficient of x²

Product of zeroes = constant TERM/coefficient of x²

SOLUTION:

Let p(x) = 4√3x² +5x -2√3

4√3x² +8x -3x -2√3

[By splitting the middle term]

4x (√3x +2) - √3(√3x +2)

(4x-√3) (√3x +2)

To find ZEROS, put p(x)= 0

(4x-√3)= 0 or  (√3x +2)= 0

4x = √3    or √3x = -2

x= √3/4   or x = -2/√3

Hence, zeroes of the polynomial are √3/4 and -2/√3.

Verification:

Sum of zeroes = (√3/4) +(-2/√3)

- coefficient of x/coefficient of x² =√3/4 -2/√3

- 5/4√3 = (√3×√3)-(2×4)/4√3

-5/4√3 =(3-8)/4√3

- 5/4√3 =-5/4√3

Product of zeroes = (√3/4) (-2/√3)= -½

constant term/coefficient of x² = -½

-2√3/ 4√3 = -½

-½ = -½

So, the relationship between the zeroes and its coefficients is verified.

as above same LOGIC for

(i)

2

1

LET us assume

2

1

is rational.

So we can write this number as

2

1

=

b

a

---- (1)

Here, a and b are TWO co-prime numbers and b is not EQUAL to zero.

Simplify the equation (1) MULTIPLY by

2

both sides, we get

1=

b

a

2

Now, divide by b, we get

b=a

2

or

a

b

=

2

Here, a and b are integers so,

a

b

is a rational number,

so

2

should be a rational number.

But

2

is a irrational number, so it is contradictory.

Therefore,

2

1

is irrational number.

(ii) 7

5

Let us assume 7

5

is rational.

So, we can write this number as

7

5

=

b

a

---- (1)

Here, a and b are two co-prime numbers and b is not equal to zero.

Simplify the equation (1) divide by 7 both sides, we get

5

=

7b

a

Here, a and b are integers, so

7b

a

is a rational

number, so

5

should be a rational number.

But

5

is a irrational number, so it is contradictory.

Therefore, 7

5

is irrational number.

(iii) 6+

2

Let us assume 6+

2

is rational.

So we can write this number as

6+

2

=

b

a

---- (1)

Here, a and b are two co-prime number and b is not equal to zero.

Simplify the equation (1) subtract 6 on both sides, we get

2

=

b

a

−6

2

=

b

a−6b

Here, a and b are integers so,

b

a−6b

is a rational

number, so

2

should be a rational number.

But

2

is a irrational number, so it is contradictory.

Therefore, 6+

2

is irrational number

6 (SIX) is the ANSWER

Step-by-step EXPLANATION:

he have 6 MANGOES

Step-by-step explanation:

6 pipes FILL tank in 2 HRS

1 PIPE fill tank in 6×2 hrs

12 pipe fill tank in 6×2/12 hrs

= 1 hour

time taken for 12 pipes to fill 10 tanks = 10 × 1= 10 hrs

Ans- 3 HOURS
First hour- 1/4 of the bucket is filled
Second hour- 1/4+1/2 bucket is filled = 3/4 bucket is filled
Third hour 1/4 is LEFT which is filled by P1.
