4.	Find the no. by wich (-6)power-1 should be multiplied so that the product becomes 9 power -1
Answer» It is pretty EASY to solve it if you've a little basics of Indices and some of its law. So, ACCORDING to the question we're asked to find a number which when mutiplied by (-6)power-1 gives product as 9 power -1. Let us assume that number to be A. So, (-6)power-1 x A = 9 power -1 or, -(1/6) x A = 1/9 [ Anything to the power -1 is the inverse of the number. ] after simplifying we are KEEPING A in LHS to evaluate its value which is our PRIME objective and transferring EVERYTHING else in RHS. or, A = -(6/9) = -(2/3) (Ans) Therefore on multiplying -(2/3) with (-6)power-1 we can get 9 power -1 as product.

Find the no. by wich (-6)power-1 should be multiplied so that the product becomes 9 power -1

Answer»

It is pretty EASY to solve it if you've a little basics of Indices and some of its law.

So, ACCORDING to the question we're asked to find a number which when mutiplied by (-6)power-1 gives product as 9 power -1.

Let us assume that number to be A.

So, (-6)power-1 x A = 9 power -1

or, -(1/6) x A = 1/9 [ Anything to the power -1 is the inverse of the number. ]

after simplifying we are KEEPING A in LHS to evaluate its value which is our PRIME objective and transferring EVERYTHING else in RHS.

or, A = -(6/9) = -(2/3) (Ans)

Therefore on multiplying -(2/3) with (-6)power-1 we can get 9 power -1 as product.

a labourer is engaged for 15 days on the condition that he will receive Rs 80 for each day he will he works and he will be fined Rs 10 for each day he is absent if he receives rupees 570 in all for how many days did he remain absent

Answer»

LET the no. of days he remained ABSENT be x

no. of days present=15-x

total no. of days=15 days

money recieved EVERY day when present = rs 80

loss when ONE day absent = rs 10

ATQ

80(15-x)-10x=570

1200-80x-10x=570

1200-570=90x

90x=630

x=7

33.

Find the hcf of 576

Answer»

The factors of 576 are

576 = 2*288

= 2*2*144

= 2*2*2*72

= 2*2*2*2*36

= 2*2*2*2*2*18

= 2*2*2*2*2*2*9

= 2*2*2*2*2*2*3*3

HCF is ALWAYS of any 2 NUMBERS .

So it's not possible that the HCF of 576 alone.

44.	Guess the cube root of 12167
Answer» HEYA MATE, HERE IS UR ANSWER. Thanks for asking this question Cube ROOT of 12167 We shall SEPARATE 12167 in to groups. The groups are 12 and 167 167 ends with 7 and we know that if 7 is at the units place of any perfect cube number then its cube root will have 3 at its units place only. THEREFORE, the DIGIT at the units place of the required cube root is taken as 3. Now considering the other group 12. 2³ = 8 and 3³ = 27 And also 8 < 12 < 27 2 is smaller than 3, therefore 2 will be taken as the digit at tens place of the required cube root. Thus, 12167 = 23 I HOPE IT HELPS U.

46.	If 4 tan theta-3=0 then find : (1)cosec theta (2)cos theta + sec theta
Answer» theta is written as A, Given, 4 tanA - 3 = 0 4 tanA = 3 tanA = 3/4 Now, tanA = 3/4 height / base = 3 / 4 Let height = 3x and base = 4x By Pythagoras THEOREM, ( 3x )^2 + ( 4x )^2 = hypotenuse^2 25x^2 = hypotenuse^2 5X = hypotenuse HENCE, ( i ) : cosecA = hypotenuse / height = 5x / 3x = 5 / 3 ( ii ) : cosA + SECA => base / hypotenuse + hypotenuse / base => 4x / 5x + 5x / 4x => 4 / 5 + 5 / 4 => ( 16 + 25 )/20 => 41/20

46.

If 4 tan theta-3=0 then find : (1)cosec theta (2)cos theta + sec theta

Answer»

theta is written as A,

Given, 4 tanA - 3 = 0

4 tanA = 3

tanA = 3/4

Now,

tanA = 3/4

height / base = 3 / 4

Let height = 3x and base = 4x

By Pythagoras THEOREM,

( 3x )^2 + ( 4x )^2 = hypotenuse^2

25x^2 = hypotenuse^2

5X = hypotenuse

HENCE,

( i ) : cosecA = hypotenuse / height

= 5x / 3x

= 5 / 3

( ii ) :

cosA + SECA

=> base / hypotenuse + hypotenuse / base

=> 4x / 5x + 5x / 4x

=> 4 / 5 + 5 / 4

=> ( 16 + 25 )/20

=> 41/20

Answer» The number is 10x+y And x=3y (EQUATION 1) A.q. (10y+x)+(10x+y)=88 11x+11y=88 11(x+y)=88 x+y=88/11 x+y=8 Frim equation 1 x=3y So, 3y+y=8 4y=8 y=8/4 y=2 And x=3y =3(2) =6 Hence the number is 62.
