5.	The ratio of yhe lenght of a rectangular field to its width is 5:2 . Find its lenght if the width is 40 metres.
Answer» Given:- ratio of rectangular FIELD = 5:2 and, WIDTH = 40 METRES *Find* :- length of rectangular field=? Solution, Let the ratio of length = 5x and ratio of breadth = 2X A/q ratio of breadth = 2x => 2x = 40 => x = 40/2 => x = 20 So, length of rectangular field is = 5x = 5×20 = 100 Hence, Its length is 100 metres.

5.

The ratio of yhe lenght of a rectangular field to its width is 5:2 . Find its lenght if the width is 40 metres.

Answer»

Given:-

ratio of rectangular FIELD = 5:2

and,

WIDTH = 40 METRES

Find :-

length of rectangular field=?

Solution,

Let the ratio of length = 5x

and ratio of breadth = 2X

A/q

ratio of breadth = 2x

=> 2x = 40

=> x = 40/2

=> x = 20

So,

length of rectangular field is = 5x

= 5×20

= 100

Hence,

Its length is 100 metres.

26.	Find the sum of series 4+12+20+28+ +100terms
Answer» Given , FIRST term (a) = 4 Common difference (d) = 8 Last term (an) = 100 We know that , the NTH term of an AP is given by $\boxed{ \sf{ a_{<klux>N</klux>} = a + (n - 1)d }}$ THUS , $\implies \tt 100 = 4 + (n - 1)8$ $\implies \tt 96 = (n - 1)8$ $\implies \tt 12 = n - 1$ $\implies \tt n = 13$ Now , the sum of first n terms of an AP is given by $\boxed { \sf{ S_{n} = \frac{n}{2}(a + a_{n}) }}$ Thus , $\implies \tt sum = \frac{13}{2} (4 + 100)$ $\implies \tt sum =13 \times 52$ $\implies \tt sum =<klux>676</klux>$ ★ The sum of given series is 676

Find the sum of series 4+12+20+28+ +100terms

Answer»

Given ,

FIRST term (a) = 4

Common difference (d) = 8

Last term (an) = 100

We know that , the NTH term of an AP is given by

$\boxed{ \sf{ a_{<klux>N</klux>} = a + (n - 1)d }}$

THUS ,

$\implies \tt 100 = 4 + (n - 1)8$

$\implies \tt 96 = (n - 1)8$

$\implies \tt 12 = n - 1$

$\implies \tt n = 13$

Now , the sum of first n terms of an AP is given by

$\boxed { \sf{ S_{n} = \frac{n}{2}(a + a_{n}) }}$

Thus ,

$\implies \tt sum = \frac{13}{2} (4 + 100)$

$\implies \tt sum =13 \times 52$

$\implies \tt sum =<klux>676</klux>$

★ The sum of given series is 676

40.

Site of a triangle are in the ratio of 12 to 17 is 225

Answer»

Step-by-step explanation:

12:17 =225

let RATIO be 12X, 17x

12x+17x=225

29x=225

X =225/29

X = 7.75

12*7.75=93
17*7.75=131.75

41.

the angle of elevation of the top of a tower from certain point is 30°.if the observer moves 20m towards the tower, the angle of elevation of the top increases 60°. find the height of the tower.

Answer»

✭ REFER to the ATTACHMENT for DIAGRAM

In Δ ABD ,

$\implies \tt \tan(30) = \frac{h}{x}$

$\implies \tt \frac{1}{ \sqrt{3} } = \frac{h}{x}$

$\implies \tt x = \sqrt{3} h$

Now , in Δ ACD

$\implies \tt \tan(60) = \frac{h}{x - 20}$

$\implies \tt \sqrt{3} = \frac{h}{x - 20}$

$\implies \tt \sqrt{3} = \frac{h}{( \sqrt{3}h - 20) }$

$\implies \tt 3h - 20 \sqrt{3} = h$

$\implies \tt 2h = 20 \sqrt{3}$

$\implies \tt h = 10 \sqrt{3} \: m$

✭ The height of tower is 10√3 meter

If (y + 1/y) = 8 then, (y² +1/y²) is

Answer»

$\huge\red {\bf {\underline {Solution:-}}}$

${\tt {y + \frac{1}{y} = 8}}$

$⇒{\tt { {(y + \frac{1}{y}) }^{2} = {8}^{2}}}$

$⇒{\tt { {y}^{2} + 2 \times y \times \frac{1}{y} + \frac{1}{ {y}^{2} } = 64}}$

$⇒ {\tt {{y}^{2} + 2 + \frac{1}{ {y}^{2} } = 64}}$

$⇒{\tt { {y}^{2} + \frac{1}{ {y}^{2} } = 64 - 2}}$

$⇒{\tt { {y}^{2} + \frac{1}{ {y}^{2} } = 62}}$
