2.	2. The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more thantwice its breadth. What are the length and the breadth of the pool?
Answer» Step-by-step explanation: Let the breadth of the swimming POOL be x. ATQ, LENGTH= 2x+2 Breadth= x Perimeter= 2(2x+2+x)=154 =2(3x+2)=154 =3x+2=154/2 =3x=77-2 =x=75/3 Breadth=x=25m THEREFORE, Length= 2x+2 =2(25)+2 =50+2=52m So, Length= 52m and Breadth=25m

2. The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more thantwice its breadth. What are the length and the breadth of the pool?

Answer»

Step-by-step explanation:

Let the breadth of the swimming POOL be x.

ATQ,

LENGTH= 2x+2

Breadth= x

Perimeter= 2(2x+2+x)=154

=2(3x+2)=154

=3x+2=154/2

=3x=77-2

=x=75/3

Breadth=x=25m

THEREFORE, Length= 2x+2

=2(25)+2

=50+2=52m

So, Length= 52m and Breadth=25m

★ Question ★

★ Factorise the following expressions -

1) a^4 - b^4

2) p^4 - 81

3) x^4 - (y+z)^4

4) x^4 - (x-z)^4

★ Solution ★

_________________________

$1) \bf \: Given \: a {}^{4} - b {}^{4} \: = (a {}^{2} ) {}^{2} - (b {}^{2} ) {}^{2}$

$\bf = (a {}^{2} + b {}^{2} )(a {}^{2} - b {}^{2} )$

Formula :-

$\bf(x {}^{2} - {y}^{2} = (x + y)(x - y))$

THEREFORE answer

$\red{ = >} \bf \: ( {a}^{2} + {b}^{2} )(a + b)(a - b)$

_________________________

$\bf \: 2) \: given \: = {p}^{4} - 81$

$= \bf {p}^{4} - {3}^{4}$

$= \bf( {p}^{2} - {3}^{2} )( {p }^{2} + {3}^{2} )$

$\bf= (p - 3)(p + 3)( {p}^{2} - {3}^{2})$

_________________________

$\bf \: 3) Given \: = {x}^{4} - (y + z {}^{4} )$

$\bf = ( {x}^{2} ) {}^{2} - ({(y + z) {}^{2} }) {}^{2}$

$\bf = ( {x}^{2} + (y + z) {}^{2} )( {x}^{2} - (y + z) {}^{2} )$

$\bf = ( {x}^{2} + (y + z) {}^{2} )(x + y + z)(x - y - z)$

$\bf = ( {x}^{2} + {y}^{2} + {z}^{2} + 2yz)(x + y + z)(x - y - z)$

$\bf = 1 \times ( {x}^{2} + {y}^{2} + {z}^{2} ) \times (x + y + z) \times (x - y - z)$

_________________________

$\bf4) Given \: = {x}^{4} - (x - z) {}^{4}$

$\bf = ( {x}^{2} ) {}^{2} - ((x - z) {}^{2}) {}^{2}$

$\bf = ( {x}^{2} + (x - z) {}^{2} )( {x}^{2} - (x - z) {}^{2} ) {}^{2}$

$\bf= ( {x}^{2} + {x}^{2} - 2xz + {z}^{2} )(x + x - z)(x - x - z)$

$\bf = (2 {x}^{2} - 2xz + {z}^{2} )(2x - z)(z)$

_________________________

★ Question ★

A GRANDFATHER is ten tires older than his grandson. He is also 54 yers old then him. Their present age?

★ Solution ★

Let man’s present age to be x and his grandson’s be y

$\bf \: x=10y ...(1)$

$\bf \: x=y+54 ...(2)$

Put equation one in equation 2

$\bf \: 10y=y+54$

$\bf10y-y=54$

$\bf9y=54$

$\bf \: y= \frac{54}{9}$

$\bf \: Y=6$

$\bf \: X=10y$

$\bf \: X=10 \times 6$

$\bf \: X=60$

Man’s present age is 60 YEAR and his grandson's present age is 6 years

_________________________

★ Question ★

Gopi's age is 3 ties his son age. 10 years ago he was five time times his son age. Present age of both?

★ Solution ★

$\bf \: Let \: Gopi's \: son \: age =x$

$\bf \: Gopi's \: age =3x$

Ten years ago, he was 5 times the age of his son.

$\bf \: Therefore, 3x−10=5(x−10)$

$\bf3x−10=5x−50$

$\bf2x=40$

$\bf \: x=20$

Gopi's son is 20 yrs old

Gopi is 3x=3×20=60 yrs old.

26.

Plz answer these word problem and both question

Answer»

Step-by-step explanation:

hello friend

1) Mean = sum of OBSERVATIONS/ no of observations

= 34+72+25+50+36+42+40+68+25+32+48+70+65+58+45/50

add those numbers and divide by 15

2) mode is most repeated value so mode is 25 which is repeated twice

3) median is mid value arrange the given observations in ascending or descending ORDER

25,25,32,34,36,40,42,45,48,50,58,65,68,70,72

so median is 45 which is mid term.

2)given

3(2x-1)+7x-8

by simplification we get 6x-3+7x-8

so 13X -11 is simplified expression

now substitute x = 2 in 13x- 11

we get 13(2)-11 = 26-11 =15

PLEASE calculate the mean.

hope it helps you

50.	The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
Answer» Given: ✰ The difference of a number and 6 is the same as 5 TIMES the SUM of the number and 2. To find: ✠ The number. Solution: Let's understand the concept FIRST! First we will assume the number as x, then we know that the difference of a number and 6 which means 6 substracted from the number i.e, x - 6 is equal to the 5 times the sum of the number and 2 that means we will add 2 to the number ( x + 2 ) and then 5 times the given term i.e, 5 multiplied by the given term 5( x + 2 ) . So, they both are equal. Thus, forming an requisite equation and doing the required calculations, we will find out the value of x i.e, the required number. Let's find out...! *According* to question, ➤ x - 6 = 5( x + 2) ➤ x - 6 = 5x + 10 ➤ 5x - x = - 6 - 10 ➤ 4x = - 16 ➤ x = -16/4 ➤ x = - 4 ∴ The required number = - 4 _______________________________

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?

Answer»

Given:

✰ The difference of a number and 6 is the same as 5 TIMES the SUM of the number and 2.

To find:

✠ The number.

Solution:

Let's understand the concept FIRST! First we will assume the number as x, then we know that the difference of a number and 6 which means 6 substracted from the number i.e, x - 6 is equal to the 5 times the sum of the number and 2 that means we will add 2 to the number ( x + 2 ) and then 5 times the given term i.e, 5 multiplied by the given term 5( x + 2 ) . So, they both are equal. Thus, forming an requisite equation and doing the required calculations, we will find out the value of x i.e, the required number.

Let's find out...!

According to question,

➤ x - 6 = 5( x + 2)

➤ x - 6 = 5x + 10

➤ 5x - x = - 6 - 10

➤ 4x = - 16

➤ x = -16/4

➤ x = - 4

∴ The required number = - 4
