Answer» ong>Answer: -979 Step-by-step explanation: SN= n/2 (2A+(n-1)d) n=22, a=8, d= -5 Sn= 22/2 (2 (8)+(22-1)(-5)) Sn=11 (16+21 (-5)) Sn=11 (16-105) Sn= 11 (-89) Sn= -979

1.

Find the sum of the first 22 terms of the AP : 8, 3, -2, . . .

Answer»

ong>Answer:

-979

Step-by-step explanation:

SN= n/2 (2A+(n-1)d)

n=22, a=8, d= -5

Sn= 22/2 (2 (8)+(22-1)(-5))

Sn=11 (16+21 (-5))

Sn=11 (16-105)

Sn= 11 (-89)

Sn= -979

26.	If P(1,-2) is a point on the linesegment A( x,y) and B (-2,4) such asthat AP:PB= 2:3 find the coordinatesof A
Answer» e given, $\longrightarrow \sf{A(x, y) = ({x}_{1}, {y}_{1})}$ $\longrightarrow \sf{P(1, -2) = (\alpha, \beta)}$ $\longrightarrow \sf{B(-2, 4) = ({x}_{2}, {y}_{2})}$ $\longrightarrow \sf{AP:PB = m:<klux>N</klux> = 2:3}$ $\sf{\\ \\}$ We know by section formula, when a point $\sf{P(\alpha, \beta)}$ INTERSECTS internally a line segment AB where $\sf{A({x}_{1},{y}_{1})}$ and $\sf{B({x}_{2},{y}_{2})}$ in the ratio m : n, then:- $\quad \quad \longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$ $\quad \quad \longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$ $\sf{\\ \\}$ So, PUTTING the VALUES, For alpha, $\longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$ $\longrightarrow \sf{1 = \dfrac{(2 * -2) + (3 * x)}{2 + 3}}$ $\longrightarrow \sf{1 = \dfrac{ - 4 + 3x}{5}}$ $\longrightarrow \sf{5 = - 4 + 3x}$ $\longrightarrow \sf{9 = 3x}$ $\longrightarrow \underline{\sf{x = 3}}$ $\sf{\\ \\}$ For beta, $\longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$ $\longrightarrow \sf{-2 = \dfrac{(2 * 4) + (3 * y)}{2 + 3}}$ $\longrightarrow \sf{-2 = \dfrac{ 8 + 3y}{5}}$ $\longrightarrow \sf{-10 = 8 + 3y}$ $\longrightarrow \sf{-18 = 3y}$ $\longrightarrow \underline{\sf{y = -6}}$ $\sf{\\ \\}$ Hence the ANSWER is, $\longrightarrow{\underline{\underline{\sf{A = (3,-6)}}}}$

26.

If P(1,-2) is a point on the linesegment A( x,y) and B (-2,4) such asthat AP:PB= 2:3 find the coordinatesof A

Answer»

e given,

$\longrightarrow \sf{A(x, y) = ({x}_{1}, {y}_{1})}$

$\longrightarrow \sf{P(1, -2) = (\alpha, \beta)}$

$\longrightarrow \sf{B(-2, 4) = ({x}_{2}, {y}_{2})}$

$\longrightarrow \sf{AP:PB = m:<klux>N</klux> = 2:3}$

$\sf{\\ \\}$

We know by section formula, when a point $\sf{P(\alpha, \beta)}$ INTERSECTS internally a line segment AB where $\sf{A({x}_{1},{y}_{1})}$ and $\sf{B({x}_{2},{y}_{2})}$ in the ratio m : n, then:-

$\quad \quad \longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$

$\quad \quad \longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$

$\sf{\\ \\}$

So, PUTTING the VALUES,

For alpha,

$\longrightarrow \sf{\alpha = \dfrac{m{x}_{2} + n{x}_{1}}{m + n}}$

$\longrightarrow \sf{1 = \dfrac{(2 * -2) + (3 * x)}{2 + 3}}$

$\longrightarrow \sf{1 = \dfrac{ - 4 + 3x}{5}}$

$\longrightarrow \sf{5 = - 4 + 3x}$

$\longrightarrow \sf{9 = 3x}$

$\longrightarrow \underline{\sf{x = 3}}$

$\sf{\\ \\}$

For beta,

$\longrightarrow \sf{\beta = \dfrac{m{y}_{2} + n{y}_{1}}{m + n}}$

$\longrightarrow \sf{-2 = \dfrac{(2 * 4) + (3 * y)}{2 + 3}}$

$\longrightarrow \sf{-2 = \dfrac{ 8 + 3y}{5}}$

$\longrightarrow \sf{-10 = 8 + 3y}$

$\longrightarrow \sf{-18 = 3y}$

$\longrightarrow \underline{\sf{y = -6}}$

$\sf{\\ \\}$

Hence the ANSWER is,

$\longrightarrow{\underline{\underline{\sf{A = (3,-6)}}}}$

The denominator of a rational number is 1 more than the numerator. If the numerator is reduced by 2 and denominator is increased by 3, the rational no. reduces to ¼. Find the rational number

Answer»

SOLUTION :-

Let,

NUMERATOR = x

Denominator = y

According to the first condition,

$\longrightarrow\sf y= x+1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ........................(1)$

According to the second condition,

$\longrightarrow\sf \dfrac{x-<klux>2</klux>}{y+3}=\dfrac{1}{<klux>4</klux>} \\\\\longrightarrow\sf 4(x-2)=y+3 \\\\\longrightarrow 4x-8 = y+3 \\\\\longrightarrow 4x-y = 3+8 \\\\\longrightarrow 4x-y = 11 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ........................(2)$

Substitute y = x + 1 in equation (2),

$\longrightarrow\sf 4x-(x+1)=11\\\\\longrightarrow 4x-x-1= 11 \\\\\longrightarrow 3x= 12 \\\\\longrightarrow \bf x = 4$

Numerator = 4

Denominator = 4 + 1 = 5

$\bf FRACTION = \dfrac{4}{5}$

Construction:- E be the point on CD. Let, AE is perpendicular to CD. Hence we can write it as => AB = ED = 15CM ...... ( 1 ) => BD = AE = 12cm ...... ( 2 ) { According to construction } Δ AEC is a right angle triangle. To find length of CE => CE = CD - ED => CE = 24m - 15m { from ( 1 )} => CE = 9m ...... ( 3 ) Now we use Pythagoras theorem to distance between tops of poles AB & CD { means distance AC } { from ( 2 ) & ( 3 )} => (AC)² = (AE)² + (CE)² => (AC)² = ( 12 )² + ( 9 )² => (AC)² = 144 + 81 => (AC)² = 225 => AC = √225 => AC = 15m Hence distance between the tops of poles is 15m .

{ ACCORDING to question}

Let, AB & CD be the two pole's of heights 15m and 24m respectively and they stand on a plane ground.

=> AB = 15m & CD = 24m

Let, assume that AB & CD Both are perpendicular to ground. mean's they are parallel to each other.

Construction:- E be the point on CD.

Let, AE is perpendicular to CD.

Hence we can write it as

=> AB = ED = 15CM ...... ( 1 )

=> BD = AE = 12cm ...... ( 2 )

{ According to construction }

Δ AEC is a right angle triangle.

To find length of CE

=> CE = CD - ED

=> CE = 24m - 15m { from ( 1 )}

=> CE = 9m ...... ( 3 )

Now we use Pythagoras theorem to distance between tops of poles AB & CD

{ means distance AC }

{ from ( 2 ) & ( 3 )}

=> (AC)² = (AE)² + (CE)²

=> (AC)² = ( 12 )² + ( 9 )²

=> (AC)² = 144 + 81

=> (AC)² = 225

=> AC = √225

=> AC = 15m

Hence distance between the

tops of poles is 15m .

Answer» Given: Anita’s total monthly expenses are equal to 2/3 of her monthly salary. She spends 1/4 of her total monthly expenses on house rent To find: What FRACTION of her monthly salary does Anita spend on house rent? Solution: Let's assume, "x" → represents Anita's monthly salary. So, Total monthly expenses of Anita is = $\frac{2}{3}^r^d \:of\:monthly\:salary = \frac{2}{3} \times x$ .... (i) It is also given that she spends $\frac{1}{4} ^t ^h$ of Anita's total monthly expenses on house rent, therefore, The fraction of Anita's monthly salary spent on house rent is, = $\frac{1}{4} \:\times\:[total\:monthly\:expenses]$ substituting from (i) = $\frac{1}{4} \:\times\:[\frac{2}{3} \times x]$ = $\frac{1}{2} \:\times\:\frac{1}{3} \times x$ = $\bold{\frac{1}{6} \times x}$ Thus, Anita spends $\underline{\bold{\frac{1}{6} ^t^h}}$ of her monthly salary on house rent. ------------------------------------------------------------------------------------ Also View: MR khanna spent 83% of his salary and saved 1870 rupees.

Anita’s total monthly expenses are equal to 2/3 of her monthly salary. She spends 1/4 of her total monthly expenses on house rent. What fraction of her monthly salary does Anita spend on house rent?

Answer» Given:

Anita’s total monthly expenses are equal to 2/3 of her monthly salary. She spends 1/4 of her total monthly expenses on house rent

To find:

What FRACTION of her monthly salary does Anita spend on house rent?

Solution:

Let's assume,

"x" → represents Anita's monthly salary.

So,

Total monthly expenses of Anita is = $\frac{2}{3}^r^d \:of\:monthly\:salary = \frac{2}{3} \times x$ .... (i)

It is also given that she spends $\frac{1}{4} ^t ^h$ of Anita's total monthly expenses on house rent, therefore,

The fraction of Anita's monthly salary spent on house rent is,

= $\frac{1}{4} \:\times\:[total\:monthly\:expenses]$

substituting from (i)

= $\frac{1}{4} \:\times\:[\frac{2}{3} \times x]$

= $\frac{1}{2} \:\times\:\frac{1}{3} \times x$

= $\bold{\frac{1}{6} \times x}$

Thus, Anita spends $\underline{\bold{\frac{1}{6} ^t^h}}$ of her monthly salary on house rent.
