Answer»

Step-by-step explanation:

Given that ,

a is a rational number

and

b is an irrational Number

In most of the cases ,

ab will be irrational SINCE product of a rational and an irrational number is 'generally' irrational.

But ,

if a = 0 [ 0 is a rational Number since 0=0/1]

and

b is an irrational number

than,

ab = 0 [ multiplication of any real number with 0 results in 0 ]

Here,

0 is a rational Number since it can be expected in p/q FORM as 0/1 where 0 and 1 are intergers and 1 is not equal to zero.

8.	Five years ago Anu was thrice as old as Sonu . After 10 year Anu will be twice as old as Sonu. How old are Anu and Sonu?
Answer» Answer:- LET the age of Anu be x YEARS and Sonu be y years. 5 Years Ago, Age of Anu = x - 5 years Age of Sonu = y - 5 years A.T.Q. ( x - 5) = 3(y-5) = x = 3Y - 15 + 5 = x = 3y - 10 _______________(1) Ten Years Later, Age of Anu = x + 10 years Age of Sonu = y + 10 years A.T.Q. ( x + 10) = 2(y + 10) = 3y - 10 + 10 = 2Y + 20 = 3y - 2y = 20 = y = 20 Substituting ( y = 20) in eq(1). = x = 3y - 10 = x = 60 - 10 = x = 50 Hence, Anu's age = x = 50 years Sonu's age = y = 20 years.

Five years ago Anu was thrice as old as Sonu . After 10 year Anu will be twice as old as Sonu. How old are Anu and Sonu?

Answer»

Answer:-

LET the age of Anu be x YEARS and Sonu be y years.

5 Years Ago,

Age of Anu = x - 5 years

Age of Sonu = y - 5 years

A.T.Q.

( x - 5) = 3(y-5)

= x = 3Y - 15 + 5

= x = 3y - 10 _______________(1)

Ten Years Later,

Age of Anu = x + 10 years

Age of Sonu = y + 10 years

A.T.Q.

( x + 10) = 2(y + 10)

= 3y - 10 + 10 = 2Y + 20

= 3y - 2y = 20

= y = 20

Substituting ( y = 20) in eq(1).

= x = 3y - 10

= x = 60 - 10

= x = 50

Hence,

Anu's age = x = 50 years

Sonu's age = y = 20 years.

13.

In the figure, the perimeter of the shaded region is 12π cm. Find the value of x.

Answer»

GIVEN:

The perimeter of the shaded region is 12π CM.

TO FIND:

What is the VALUE of X ?

SOLUTION:

We KNOW that, the perimeter of the shaded region is 12π

We have to find the value of 'x'

We know that, the Circumference of the semicircle is:- $\bf{ \frac{2 \pi r}{2} }$

$\bf{\star \: Circumstance = \pi r \: \star }$

Diameter of larger semicircle = (x + x) cm

$\rm{ Radius = \frac{Diameter}{2} = \frac{2x}{2}}$

$\bf{ \star \: Radius = x \: cm \: \star }$

❛ The radius of larger semicircle is x cm ❜

Diameter of smaller semicircle = x cm

$\rm{ Radius = \frac{Diameter}{2} = \frac{x}{2}}$

$\bf{\star \: Radius = \frac{x}{2} \: cm \: \star }$

❛ The radius of smaller semicircle is x/2 cm ❜

According to question:-

On putting the given values in the formula, we get

$\rm{\mapsto \pi x - \pi \frac{x}{2} + \pi \frac{x}{2} = <klux>12</klux> \pi }$

$\rm{\mapsto \pi x = 12 \pi }$

$\bf{\mapsto \: \star \: x = 12 \: \star }$

∴ Radius = 12 cm

❛ Hence, the value of x is 12 cm ❜

the area of rectangular garden is 77/2msquare .find the length of the garden if its breadth is 49/12m. also find the cost of fencing the garden at rupees 63/5per m.

Answer»

Answer

LET the length of the RECTANGLE be x

Breadth of the rectangle = 49/12 m

Area of the rectangle = 77/2 m^2

[FORMULAE used]

length× breadth= Area

[Solution]

Area of the rectangle = 77/2m^2

length× breadth= 77/2 m^2

x × 49/12m = 77/2 m^2

x= 77/2m^2 ÷ 49/12m

x=77/2m^2×12/49m

x= 66/7 m

Therefore the length of the rectangle= 66/7m

[To Find]

The cost of fencing the rectangular GARDEN = 63/5 per metre square

To find the cost of fencing of the 77/2 m^2

Rs 63/5×77/2

Rs 4851/10

Rs 485.1

Answer»

Answer:

1. If they WORK together, work done in a day will be 9/20.

2. If they work together for 2 DAYS, 1/10th of the work will be left.

Step-by-step EXPLANATION:

Given,

A will complete a work in = 4 days

B will complete a work in = 5 days

Work by A = 1/4

Work by B = 1/5

If they work together, work done will be = (1/4+1/5)

= (5+4)/20

= 9/20

Total work = 1

Previously calculated that if they work together, work done in a day will be 9/20.

Then,

Work Done in 2 days = 9/20+9/20

= 18/20

Work left = (1-18/20)

Conversely, we can SAY that if (x - a) is a factor of p(x), then p(a) is it's one zero.

$\mathtt{\underline{HERE,}}$

Here we can see that the (x - a) term is equal to (x -1)

So we can say that a = 1

We have to PROVE p(a) that is p(1) = 0, to show that (x - 1) is a factor.

We know,

p(x) = 2√2x³ + 5√2x² -7√2

$\underline{\green{\bf{finding\:p(1):-}}}$

p(1) = (2√2 * 1 * 1 * 1) + (5√2 * 1 * 1) - 7√2

$\implies$ p(1)= 2√2 + 5√2 - 7√2

$\implies$ p(1) = 7√2 - 7√2

$\implies$ p(1) = 0

$\sf{\orange{p(1)\:=\:0\:hence\:(x\:-\:1)\:is\:a\:factor\:of\:p(x)}}$

3. Check whether (5,-2), (6, 4) and (7,-2) are the vertices of an isosceles triangle

Answer»

5 -2) (6 4) and (7 -2) are the VERTICES of an isosceles triangle

A ( 5 , -2)

B (6 , 4)

C ( 7 , -2)

Length of each sides

AB = √(6 - 5)² + (4+2)² = √( 1 + 36) = √37 units

BC = √(7 - 6)² + (-2-4)² = √(1 + 36) = √37 units

CA = √(7-5)² + (-2+2)² = √(4+0) = 2 units

AB = BC = √37

Hence verified that these vertices are of an isosceles triangles

A small indoor greenhouse (herbarium) is made entirely of glass panes (includingbase) held together with tape. It is 30 cm long, 25 cm wide and 25 cm high,6) What is the area of the glass?6) How much of tape is needed for all the 12 edges?

Answer»

Answer:

6) Area = 4250 cm²

6) 320 cm of tape is required

Step-by-step explanation:

6) Area of glass NEEDED = TSA of CUBOID

= 2(lb + bh + lh)

= 2(30x25 + 25X25 + 30x25)

= 2(750 + 625 + 750)

= 2(2125)

= 4250 cm²//

6) Tape needed for all 12 edges = 4(l + b + h)

= 4(30 + 25 + 25)
