5.

(1+sintheta)(1-sintheta)/(1+costheta)(1-costheta) evaluate if cot theta=7/8

Answer»

ANSWER:

(1-sinthita)(1+sinthita)/(1-costhita)(1+costhita)=1-sin2thita/ 1-cos2thita

=cos2thita/sin2thita ( :1-sin2thita=cos2thita and 1-cos2thita= sin2thita)

=COT2THITA

And cotthita= 7/8

So cot2thita= 49/64

Find two numbers each of three digit such that their gcd is 8 and their LCM is 1768

Answer»

Answer: The two numbers of three digits such that their gcd is 8 and their LCM is 1768 are 104 and 136.

Step-by-step EXPLANATION:

Dividing the LCM by the gcd, we get:

1768/8= 221

Now, FACTORIZE the resulted number, 221 as follow:

221= 13x17

There is only two factors, i.e. 13 and 17.

So,

The first number= 8x13= 104

The second number= 8x17= 136

Answer» Hii !! Let DENOMINATOR of rational number be X. Numerator = ( X - 2 ). Rational number = Numerator/Denominator = X - 2 / X. According to question, X - 2 - 2 / X + 2 = 1/3 X - 4 / X + 2 = 1/3 X + 2 = 3 ( X - 4 ) x+ 2 = 3X - 12 3X - X = 2 + 12 2X = 14 X = 7 Denominator = X = 7 And, Numerator = X - 2 = 5. Therefore, Required Rational number = 5/7.

The total number of ways in which 9 different toys can be distributed among 3

Answer»

Answer: There are 504 ways in which 9 different toys can be DISTRIBUTED among 3.

Step-by-step explanation:

Here, we use the CONCEPT of permutation as follow:

The number of ways= P(9,3)

=> P(9,3)= 9!/(9-3)!

=> 9!/6!

Expanding 9! up to 6!, we GET:

=> 9x8x7x6!/6!

=> 9x8x7

=> 504

47.	The sum of two numbers is 84.The first is 9 morve than 4 times the second
Answer» Answer: Required numbers are 15 and 69. Step-by-step explanation: Let the required two numbers are X and y. GIVEN that the sum of both the numbers is 84. So, x + y =84 ...( i ) According to the question : - First number is 9 more than 4 times of the second number. So, x = 9 + ( 4 times of y ) ⇒ x = 9 + ( 4 x y ) ⇒ x = 9 + 4Y Now, numbers are 9 + 4y and y. Substitute the value of 9 + 4y in ( i ) ⇒ 9 + 4y + y = 84 ⇒ 9 + 5y = 84 ⇒ 5y = 84 - 9 ⇒ 5y = 75 ⇒ y = 75 / 5 ⇒ y = 15 Therefore, Numbers are y = 15 and 9 + 4y ⇒ 9 + 4( 15 ) ⇒ 9 + 60 ⇒ 69.

47.

The sum of two numbers is 84.The first is 9 morve than 4 times the second

Answer»

Answer:

Required numbers are 15 and 69.

Step-by-step explanation:

Let the required two numbers are X and y.

GIVEN that the sum of both the numbers is 84.

So, x + y =84 ...( i )

According to the question : -

First number is 9 more than 4 times of the second number.

So, x = 9 + ( 4 times of y )

⇒ x = 9 + ( 4 x y )

⇒ x = 9 + 4Y

Now, numbers are 9 + 4y and y.

Substitute the value of 9 + 4y in ( i )

⇒ 9 + 4y + y = 84

⇒ 9 + 5y = 84

⇒ 5y = 84 - 9

⇒ 5y = 75

⇒ y = 75 / 5

⇒ y = 15

Therefore,

Numbers are y = 15 and 9 + 4y ⇒ 9 + 4( 15 ) ⇒ 9 + 60 ⇒ 69.
