Answer» $\huge\bold\pink{Answer :-}$ __________ Prefer the above attachment! (: ______ There’s a pattern between the two equations: the numerators in the first two terms are products of the numerators in the first equation and the number 3. The problem is that the NUMERATOR of the term on the opposite side of the equation is not multiplied by 3. If it were, it would LOOK like this: 6/y + 9/x = 21/xy Because all THREE terms are not of the same proportion there are no solutions to this system of equations. They each describe their terms differently so they cannot SHARE any terms (which is what happens in a system of equations). THUS, these equations are *not* of the same system! _________

Divide the following by the long division method of x² -- x + 1 by x + 1

Divide 3X3 – 5x2 + 10x – 3 by 3x + 1

Looking only at the leading terms, I divide 3x3 by 3x to get X2. This is what I put on top:

I multiply this x2 by the 3x + 1 to get 3x3 + 1x2, which I put underneath:

3x^3 + 3x put down underneath the dividend

Then I change the signs, ADD down, and remember to carry down the "+10x – 3" from the original dividend, giving me a new bottom line of –6x2 + 10x – 3:

(3x^3 – 5x^2 + 10x – 3) – (3x^3 + 1x^2) = –6x^2 + 10x – 3

Dividing the new leading term, –6x2, by the divisor's leading term, 3x, I get –2x, so I put this on top:

(–6x^2) ÷ (3x) = –2x, which GOES on top

Then I multiply –2x by 3x + 1 to get –6x2 – 2x, which I put underneath. I change signs, add down, and remember to carry down the "–3 from the dividend:

(–6x^2 + 10x –3) – (–6x^2 – 2x) = 12x – 3, which is my new last line

Answer» Step-by-step EXPLANATION: We KNOW that, $\cot(30) = \sqrt{3}$ $\sin(60) = \frac{ \sqrt{3} }{2}$ $\cos(45) = \frac{1}{2}$ The QUESTION, $\frac{4}{ \cot(30) \times \cot(30) } + \frac{1}{ \sin(60) \times \sin(60) } - ( \cos(45) \times \cos(45) )$ $= \frac{4}{ { \sqrt{3} }^{2} } + \frac{1}{ { (\frac{ \sqrt{3} }{2} )}^{2} } - { \frac{1}{2} }^{2}$ $= \frac{4}{3} + \frac{4}{3} - \frac{1}{4}$ $= \frac{29}{12}$

7. Evaluate: (4 / Cot² 30°) + (1 / sin² 60° ) - cos² 45°

Answer»

Step-by-step EXPLANATION:

We KNOW that,

$\cot(30) = \sqrt{3}$

$\sin(60) = \frac{ \sqrt{3} }{2}$

$\cos(45) = \frac{1}{2}$

The QUESTION,

$\frac{4}{ \cot(30) \times \cot(30) } + \frac{1}{ \sin(60) \times \sin(60) } - ( \cos(45) \times \cos(45) )$

$= \frac{4}{ { \sqrt{3} }^{2} } + \frac{1}{ { (\frac{ \sqrt{3} }{2} )}^{2} } - { \frac{1}{2} }^{2}$

$= \frac{4}{3} + \frac{4}{3} - \frac{1}{4}$

$= \frac{29}{12}$

A well of diameter 3 m is dug 21 m deep. The earth taken out of it is spread evenly all around it to a width of 4 m to form an embankment, find the height of embankment.

Answer»

Answer:

Answer:

0.5235 m.

Step-by-step explanation:

Diameter of well = 3 m

Radius of well = Diameter/2 = 3/2 =1.5 m

Depth of well = 21 m

Well is in the shape of cylinder

Volume of well = \pi r^{2} hπr

2

h

= 3.14 \times 1.5 ^{2} \times 21=3.14×1.5

2

×21

= 148.365 m^3=148.365m

3

Radius of embankment = Radius of well + width

= 1.5 + 8

= 9.5 m

Since , Embankment is in the shape of cylinder .

So, volume of embankment = \pi r^{2} hπr

2

h

= 3.14 \times 9.5^{2} \times h=3.14×9.5

2

×h

= 283.385h=283.385h

Since the earth is taken out from the well is USED to make embankment .

So, volume will be equal.

\Rightarrow 148.365 =283.385h⇒148.365=283.385h

\Rightarrow \FRAC{148.365}{283.385}=h⇒

283.385

148.365

=h

\Rightarrow 0.5235=h⇒0.5235=h

Hence the height of the embankment is 0.5235 m.

Answer» Answer: There are 5 distinct LETTERS (B,A,R,C & K) in the word BARRACK with A &R being REPEATED twice. To form 4-lettered words, there will be 4 situations viz. (i) all 4 different (ii) 2 are different and other 2 are A's (iii) 2 are different and other 2 are R's (iv) 2 are A's and other 2 are R's. Case (i): The first letter out of 5 can be chosen in 5 ways. The second letter can be chosen out of REMAINING 4 in 4 ways. Again, the third letter can be chosen out of remaining 3 in 3 ways and lastly the FOURTH letter can be chosen out of remaining 2 in 2 ways. Hence, total arrangements of 4 lettered words with no repetition is 5432 = 120. Case (ii): Here, 2 letters are different and other 2 letters are both A . But, 2 letters can be chosen out of 4 ( B,R,C & K) in C(4,2)=6 ways. Again, this 4-lettered word with 2 A 's can be arranged in 4!/2!=12 ways. So, total arrangement is 612 =72. Case (iii) : Similarly, when 2 letters are different and 2 letters are both R , the total arrangement is also 72. Case (iv) : Here, 2 letters are both R and remaining 2 letters are both A and hence, the total arrangement is 4!/(2!∗2!)=6. So, the total number of 4 lettered words is 120+72+72+6 = 270

Answer:

There are 5 distinct LETTERS (B,A,R,C & K) in the word BARRACK with A &R being REPEATED twice. To form 4-lettered words, there will be 4 situations viz. (i) all 4 different (ii) 2 are different and other 2 are A's (iii) 2 are different and other 2 are R's (iv) 2 are A's and other 2 are R's.

Case (i): The first letter out of 5 can be chosen in 5 ways. The second letter can be chosen out of REMAINING 4 in 4 ways. Again, the third letter can be chosen out of remaining 3 in 3 ways and lastly the FOURTH letter can be chosen out of remaining 2 in 2 ways. Hence, total arrangements of 4 lettered words with no repetition is 5*4*3*2 = 120.

Case (ii): Here, 2 letters are different and other 2 letters are both A . But, 2 letters can be chosen out of 4 ( B,R,C & K) in C(4,2)=6 ways. Again, this 4-lettered word with 2 A 's can be arranged in 4!/2!=12 ways. So, total arrangement is 6*12 =72.

Case (iii) : Similarly, when 2 letters are different and 2 letters are both R , the total arrangement is also 72.

Case (iv) : Here, 2 letters are both R and remaining 2 letters are both A and hence, the total arrangement is 4!/(2!∗2!)=6.

So, the total number of 4 lettered words is 120+72+72+6 = 270

. Find the original number if the sum of digit and the number obtained by interchanging thdigits are as follows: (ii) 7, 27 more than the original number

Answer»

ANSWER:

25

Given :

Sum of the digits = 7
NUMBER obtained by interchanging the digit = 27 more than original number .

To find:

Original number

Solution :

Let the digit at ones place be x and at tens place be y .

Then , the original number BECOMES 10y + x .

A/Q ,

y + x = 7

y = 7-x .

Number FORMED after interchanging the digits = 10x + y .

A/Q ,

New number = 27 + original number

10x + y = 27 + 10y + x

10x + 7 - x = 27 + 10 (7-x) + x

9x +7 = 27 + 70 - 10x + x

9x +10x - x = 27 + 70 -7

18X = 90

x = 90/18

$\implies$ x = 5

$\implies$ y = 7-5 = 2

So , the original number is 10×2 + 5

= 20+5

= 25

New number = 52

$\boxed{ \therefore \sf \: original \: number = 25} \\ \\ \tt \: and \\ \\ \boxed{ \therefore \sf \: new \: number = 52}$

Verification :

New number- original number

= 52 - 25

= 27

Hence verified

12195.

3 equal cubes are placed adjacently in a row . find the ratio of the total surface area of the resulting cuboid to that of the sum of the surface area of 3 cubes .

Answer»

Let each SIDE of CUBE = a cm

SURFACE area of cube = 6a² cm²

sum of the 3 cubes = 6a² ⁼ 18a² cm²

length of resulting cuboid = 3a cm

breadth of resulting cuboid = a cm

height of resulting cuboid = a cm

total surface area = 2 ( lb + bh + hl )

2 ( 3a*a + a*a + a *3a )
2 ( 3a² + a + 3a² )
2 ( 7a² )
14a² cm²

ratio = t.s.a of resulting cuboid / area of cube

ratio = 18a²/ 14a²

ratio = 7/9

ratio = 7:9

3. What sum will earn an interest of 480 in 2 1/2years at the rate of 3% per annum simpleinterest

Answer»

Hello!

Here is the answer for your question!

Question:- What SUM will EARN an interest of 480 in 2 1/2 years at the rate of 3% per annum simple interest

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

Answer:-

LET the principal amount be P

P = Principal amount
r = Rate = 3%
I = intrest = 480
t = Time = 2 1/2 = 2.5 years

Formula for simple intrest:-

I = P × r × t (p = principal , r = rate, t = time, I = intrest)

substituting values ;

480 = P × 3/100 × 2.5 (3% = 3/100)

480 = P × 0.075

P = 480 ÷ 0.075

P = 6400

A sum of 6400₹ will earn an intrest of 480₹ in 2 1/2 years at an intrest rate of 3% per annum

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

Hope this helped you with your doubt :)
