5.	If the C.P. of 25 chairs is equal to the S.P. of 30chairs, find the loss percent
Answer» ANSWER: solution Step-by-step EXPLANATION: The C.P of CHAIR = 25 and S.P of chair= 30 so loss= S.P - C.P = 30-25 =5 so loss PERCENTAGE= loss/C.P × 100 5/25×100 5×100 500

5.

If the C.P. of 25 chairs is equal to the S.P. of 30chairs, find the loss percent

Answer»

ANSWER:

solution

Step-by-step EXPLANATION:

The C.P of CHAIR = 25

and S.P of chair= 30

so loss= S.P - C.P

= 30-25

=5

so loss PERCENTAGE= loss/C.P × 100

5/25×100

5×100

500

Answer» Answer Let the COORDINATES of P be (x,y,Z). The coordinates of points A and B are (4,0,0) and (−4,0,0) respectively. It is given that PA+PB=10 √(x+4)ᒾ+yᒾ+zᒾ+√(x+4)ᒾ+yᒾ+zᒾ = 10 √(x+4)ᒾ+yᒾ+zᒾ = 10-√(x+4)ᒾ+yᒾ+zᒾ On squaring both sides, we OBTAIN (x-4)ᒾ+yᒾ+zᒾ = 100+(x+4)ᒾ+yᒾ+zᒾ-20√(x+4)ᒾ+yᒾ+zᒾ xᒾ-8x+16+yᒾ+zᒾ = 100-20√(x+4)ᒾ+yᒾ+zᒾ+xᒾ+8x+16+yᒾ+zᒾ 20√(x+4)ᒾ+yᒾ+zᒾ = 100+16x 5 = √(x+4)ᒾ+yᒾ+zᒾ = (25+4x) On squaring both sides again, we obtain 25(xᒾ+8x+16+yᒾ+zᒾ) = 625+16xᒾ+200x 25xᒾ+200x+400+25yᒾ+25zᒾ = 625+16xᒾ+200x 9xᒾ+25yᒾ+25zᒾ-225 = 0 Thus the required equation is 9xᒾ+25yᒾ+25zᒾ-225 = 0

Find the equation of the set of points P, the sum of whose distances from A (4, 0, 0) and B (– 4, 0, 0) is equal to 10__________________________Spam will be Report,

Answer»

Answer

Let the COORDINATES of P be (x,y,Z).

The coordinates of points A and B are (4,0,0) and (−4,0,0) respectively.

It is given that PA+PB=10

√(x+4)ᒾ+yᒾ+zᒾ+√(x+4)ᒾ+yᒾ+zᒾ = 10

√(x+4)ᒾ+yᒾ+zᒾ = 10-√(x+4)ᒾ+yᒾ+zᒾ

On squaring both sides, we OBTAIN

(x-4)ᒾ+yᒾ+zᒾ = 100+(x+4)ᒾ+yᒾ+zᒾ-20√(x+4)ᒾ+yᒾ+zᒾ

xᒾ-8x+16+yᒾ+zᒾ = 100-20√(x+4)ᒾ+yᒾ+zᒾ+xᒾ+8x+16+yᒾ+zᒾ

20√(x+4)ᒾ+yᒾ+zᒾ = 100+16x

5 = √(x+4)ᒾ+yᒾ+zᒾ = (25+4x)

On squaring both sides again, we obtain

25(xᒾ+8x+16+yᒾ+zᒾ) = 625+16xᒾ+200x

25xᒾ+200x+400+25yᒾ+25zᒾ = 625+16xᒾ+200x

9xᒾ+25yᒾ+25zᒾ-225 = 0

Thus the required equation is 9xᒾ+25yᒾ+25zᒾ-225 = 0

9.	How to tell wild animals summary (class 10) English
Answer» ${\tt{\red{\underline{\underline{\huge{AnswEr}}}}}}$ The POET is describing the various wild animals. These animals are very dangerous and she has introduced them one by one in a very funny way. First of all she tells us about an Asian lion. She says that if you are visiting the jungles of the east and there you see an animal which has tawny skin and he roars so LOUDLY that you will die out of fear. This means that you have seen an Asian lion. Next in the line is the Bengal tiger that she has explained to be a royal animal that at once attacks and kills a man. She says by adding humour that if this BEAUTIFUL black striped animal kills you and eats you, then you have surely MET a Bengal tiger. After this, she says that if the reader met an animal that has black spotted skin and it at once jumps on him, then it means that the reader has met a leopard. Moreover, she says that if one will cry out in pain, it maybe of no use as the leopard will not stop attacking him. Then she moves on to the bear that she says will hug very tightly. This is the way to recognize a bear as it kills a person by hugging him very tightly. So, she says that the bear will continue to hug us tightly and that is the only way to recognize him. After this, she asks a question to the readers that do they know how to recognize beasts that hunt their prey. Here she explains about hyenas which she thinks have a smiling face and the crocodiles that have tears in their eyes. This can be seen when they are killing their prey. The last one in the list is the Chameleon. She says that it is a lizard - like creature which doesn’t have ears and wings just like a lizard. Only this can HELP you differentiate between a lizard and chameleon. She further says that the chameleon has a quality of changing its color according to the colour of the surface. So, to explain this she says that if the reader looks at the tree and if he can only see the tree, this means that there is a chameleon sitting on it which has already turned its color to brown just like the branch of the tree.

Step-by-step explanation:

Acc to identity -

X3 + y3 + c3 - 3XYZ = ( x+y+Z )(x2 + y2 + z2 - xy - yz - zx )

here x + y + z = 0

therefore, X3 + y 3 + z3 - 3 xyz = 0 * ( x2 + y2 + z2 - xy - yz - zx )

17.

If 15 tan theta =8 find the values of cos theta and cosec theta

Answer»

Solution :

Here, we'll use some TRIGONOMETRIC formulas.

15tanθ = 8

=> tanθ = 8/15

----------------------------

As we KNOW that :

tanθ = P/B

Here, P refers to 8 and B refers to 15

Put k in the ratio

P = 8k
B = 15k

H² = P² + B² [ PYTHAGORAS theorem ]

Put the values -

⠀⠀⠀⠀=> H² = (8k)² + (15k)²

⠀⠀⠀⠀=> H² = 64k² + 225k²

⠀⠀⠀⠀=> H² = 289k²

⠀⠀⠀⠀=> H = √289k²

⠀⠀⠀⠀=> H = 17k units

Now,

cosθ = B/H = 15k/17k = 15/17
cosecθ = H/P = 17k/8k = 17/8

----------------------------

More to know :

sinθ = P/H
cosθ = B/H
tanθ = P/B
cosecθ = H/P
secθ = H/B
cotθ = B/P

Where :

P denotes Perpendicular
B denotes BASE
H denotes Hypotenuse

Find the derivative of y =secxtanx

Answer»

GIVEN :–

• A Function y = SEC(x)TAN(x)

TO FIND :–

• Value of dy/dx = ?

SOLUTION :–

• We KNOW that –

$\\ \bf \implies \dfrac{d(u.v)}{dx} =u \dfrac{dv}{dx} + v\dfrac{du}{dx}\\$

• So that –

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x)\dfrac{d( \tan x)}{dx} + \tan(x)\dfrac{d( \sec x)}{dx}\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x)\sec^{2} (x)+ \tan(x) \{ \sec(x) .\tan(x) \}\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x)\sec^{2} (x)+ \tan(x)\sec(x) .\tan(x)\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x)\sec^{2} (x)+ \tan^{2} (x)\sec(x)\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x) \{1 + \tan^{2} (x) \}+ \tan^{2} (x)\sec(x)\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x) + \tan^{2} (x)\sec(x)+ \tan^{2} (x)\sec(x)\\$

$\\ \bf \implies \dfrac{dy}{dx} = \sec(x) + 2\tan^{2} (x)\sec(x)\\$

Answer»

Required ANSWER :

Question : -

• ( x² + 10x + 25 ) by (x+5)

Solution : -

We have to divide ( x² + 10x + 25 ) with (x+5) term using long division method

GIVEN,

• Dividend = (x² + 10x + 25)

• Divisor = (x+5)

• Quotient = ?

$\dfrac{ (x² + 10x + 25) }{(x+5)} \: = \: x \: + \: 5$

After dividing (x² + 10x + 25) with (x+5) remainder will be 0 and answer will be x+5

Now we have to verify :

So as to verify multiply the divisor with quotient.

(x+5) (x+5)

x(x+5) + 5(x+5)

x² + 5x + 5x + 25

x² + 10x + 25

HENCE, verified

A thief started running from point X at a speed of 20 km/hr, after running for 30 minutes, when he watched the police at the distance of 400 m coming from opposite direction at the speed of 30 km/hr, he turned and started running at 25 km/hr in the same direction as of police. After how much distance from point X police will catch the thief?

Answer»

GIVEN : A thief started running from point X at a speed of 20 KM/hr,

after running for 30 minutes, when he watched the police at the distance of 400 m coming from opposite direction at the speed of 30 km/hr,

he turned and started running at 25 km/hr in the same direction as of police.

To Find : After how much distance from point X police will catch the thief?

Solution:

From point X at a speed of 20 km/hr, for 30 minutes

Distance from X = 20 * (30/60) = 10 km

thief turned and started running at 25 km/hr

police man at speed of 30 km/hr

Relative speed = 5 km/hr

relative distance = 400 m = 0.4 km

time = 0.4/5 hr = 0.4 * 12 = 4.8 minutes

Distance covered in 4.8 minutes = 25 * 4.8/60 = 2 km

Hence Distance form point X = 10 - 2 = 8 km

distance from point X police will catch the thief = 8 km

4/x+3y=14 and 3/x-4y=23

Answer»

Step-by-step EXPLANATION:

Let 1/x be a. So, the equations will become,

4a+3Y = 14 -----(1)

3a-4y = 23 -----(2)

Multiplying (1) by 4 and (2) by 3 and adding them,

16a+12y + 9a-12y = 56 + 69

=> 25A = 125

=> a = 5

=> x = 1/5

From (1),

4 * 5 + 3y = 14

=> 20 + 3y = 14

=> 3y = -6

=> y = 2

So, the answer is x = 1/5 and y = 2.
