1.	Find the percentage increaseand in the area of a triangleat its each side is doubled
Answer» The area before : area1= $\frac{1}{2} \times <klux>H</klux> \times <klux>B</klux>$ Where h = HEIGHT and b = base. The area after increasing the sides, area2= $\frac{1}{2} (2h)(2b) \\ = 4( \frac{1}{2} \times h \times b)$ So the increase in area in % will be, $\frac{4( area_{1} )- (area_{1}) }{ area_{2} } \times 100 \\ \frac{3area_{1}}{area_{2}} \times 100 \\ \frac{3}{4} \times 100 \\ = 75\%$

the height of parallelogram is one third of it's base . if the area of the parallelogram is 192cm. find the height and base (4 marks)

Answer»

Given :

The height of PARALLELOGRAM is one THIRD of it's base.
AREA of the parallelogram is 192 cm²

To Find :

Base of the parallelogram.
Height of the parallelogram.

Solution :

LET the base of the parallelogram be x cm.

Let the height of the parallelogram be y cm.

Case 1 :

The height of the parallelogram is ⅓ of the base.

Equation :

$\implies$ $\sf{height\:=\:\dfrac{1}{3}\:\times\:base}$

$\implies$ $\sf{y=\dfrac{1}{3}\:\times\:x}$

$\implies$ $\sf{y=\dfrac{x}{3}\:\:\:\:(1)}$

Case 2 :

The area of the parallelogram is 192 cm².

Formula :

$\large{\boxed{\tt{Area_{parallelogram}\:=\:base\:\times\:height}}}$

Equation :

$\implies$ $\sf{192\:=\:\:base\:\times\:height}$

$\implies$ $\sf{192\:=\:x\:\times\:y}$

$\implies$ $\sf{192\:=\:x\:\times\:\dfrac{x}{3}}$ $\bold{\big[From\:equation\:(1)\:y\:=\:\dfrac{x}{3}\big]}$

$\implies$ $\sf{192\:=\:\dfrac{x^2}{3}}$

$\implies$ $\sf{192\:\times\:3\:=\:x^2}$

$\implies$ $\sf{576=x^2}$

$\implies$ $\sf{\sqrt{576}\:=\:x}$

$\implies$ $\sf{24=x}$

Substitute, x = 24 in equation (1),

$\implies$ $\sf{y=\dfrac{x}{3}}$

$\implies$ $\sf{y=\dfrac{24}{3}}$

$\implies$ $\sf{y=8}$

$\large{\boxed{\tt{\purple{Base\:of\:parallelogram\:=\:x\:=\:24\:cm}}}}$

$\large{\boxed{\tt{\purple{Height\:of\:parallelogram\:=\:y\:=\:8\:cm}}}}$

Lines AB and CD pass through the center of the adjacent picture circle. if Know that angle dcb and angle abc

Answer»

Let AB be the chord of the given circle with centre O and a radius of 10 cm.

Then AB =16 cm and OB = 10 cm

From O, DRAW OM perpendicular to AB.

We know that the perpendicular from the centre of a circle to a chord bisects the chord.

∴ BM = (162) cm=8 cm

In the right ΔOMB, we have:

OB2 = OM2 + MB2 (Pythagoras theorem)

⇒ 102 = OM2 + 82

⇒ 100 = OM2 + 64

⇒ OM2 = (100 - 64) = 36

⇒ OM=36−−√ cm=6 cm

Hence, the DISTANCE of the chord from the centre is 6 cm......

2.0123...=x

Multiplying both sides by 10000

20123.23...=10000x

Subtracting x from both sides

20123.23-2.0123=1000x-x

9999x=20121.107

x=20121.107/9999

Find the area of a rhombus whose side is is 5 cm and whose altitude is 4.8 if one of its diagonal is 8 cm long find the length of the other diagonal...?

Answer»

$\huge \underline{ \mathbb{SOLUTION:-}}$

Given:

Side of the rhombus = 5cm
Altitude of the rhombus = 48cm
Length of its ONE diagonal = 8cm

Need to find:

Length of the other diagonal

Step by step explanation:

Area of the rhombus = side×length of the altitude

=> 5×48

=> 24 sq cm

Now,

LET the length of the other diagonal be x

As we KNOW that

Area of rhombus = half the product of its diagonals

Therefore,

$\large \implies{ \frac{1}{2} \times 8 \times x = 24} \\ \large \implies{4x = 24} \\ \large \implies{x = \frac{24}{4} } \\ \large \implies{ \bold{x = <klux>6CM</klux>}}$

Hence, the length of the other diagonal is 6cm.

Answer» $\text{[math]}$ Given, sum of TWO NUMBERS = -12/3 one NUMBER = -1/3 let the other number be X so, x + (-1/3) = -12/3 x - 1/3 = -12/3 x = -12/3 + 1/3 *x = -11/3* so, Other number = -11/3

49.

The sum of two numbers is -1/3 if one of the numbers is -12/3 find other number

Answer»

$\text{[math]}$

Given,

sum of TWO NUMBERS = -12/3

one NUMBER = -1/3

let the other number be X

so,

x + (-1/3) = -12/3

x - 1/3 = -12/3

x = -12/3 + 1/3

x = -11/3

so,

Other number = -11/3
