( 17 x 11 x 2 ) + ( 17 x 11 x 5 )
By taking ( 17 x 11 ) common ,
= ( 17 x 11 ) ( 2 + 5 )
= ( 17 x 11 ) ( 7 )
= 17 x 11 x 7.
If any number can be represented in the form of product of prime numbers then that number is composite number.
Hence , ( 17 x 11 x 2 ) + ( 17 x 11 x 5 ) is a composite number.

Prime factors of 378=2*3*3*3*7 Prime factors of 180=2*2*3*3*5 Prime factors of 420=2*2*3*5*7 So, hcf of 378,180,420 is 2*3=6 LCM of 348,180,420 is 2*2*3*3*3*5*7=3780

Gaurav Seth 18 hours ago

A n s w e r

Prime factors of 378 = 2 × 3 × 3 × 3 × 7
Prime factors of 180 = 2 × 2 × 3 × 3 × 5
Prime factors of 420 = 2 × 2 × 3 × 5 × 7
So, HCF of 378, 180 and 420 is 2 × 3 = 6
And LCM of 378, 180 and 420 is 2 × 2 × 3 × 3 × 3 × 5 × 7 = 3780

Given, $P(E) = 0.05$

We know,

$P(not\ E) = 1 - P(E)$

$\therefore P(not\ E) = 1 - 0.05 = 0.95$

Hence, the probability of 'not E' is 0.95

1. Form the pair of linear equations in the following problems, and find their solutions graphically.

(i) 10 students of Class X took part in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz.

(ii) 5 pencils and 7 pens together cost 50, whereas 7 pencils and 5 pens together cost 46. Find the cost of one pencil and that of one pen.

Solution:

(i)Let there are x number of girls and y number of boys. As per the given question, the algebraic expression can be represented as follows.

x +y = 10

x– y = 4

Now, for x+y = 10 or x = 10−y, the solutions are;

For x – y = 4 or x = 4 + y, the solutions are;

The graphical representation is as follows;

Yogita Ingle 1 day, 13 hours ago

We know that the largest 5 digit number is 99999.

So here we can see that 99999 is not a perfect square as it leaves 143 as the remainder while finding it s square root.

So for finding 5 digit perfect square we will have to subtract 143 from 99999

=> 99999-143 = 99856

Hence 99856 is a perfect square whose square root is √99856 = 316.

In figure, a circle touches all the four sides of a quadrilateral ABCD_/ whose sides AB = 6 cm, BC = 7 cm and CD = 4 cm. Find AD.

<hr />

Since, length of two tangents drawn from an external point of circle are equal.
So,    AP = AS
BP = BQ DR = DS
and    RC = CQ
Adding all, we get
(AP + BP) + (DR + RC) = AS + BQ + DS + CQ
⇒ (AP + BP) + (DR + RC)
= (AS + DS) + (BQ + CQ)
⇒    AB + DC = AD + BC
⇒    6 + 4 = AD + 7
⇒    10 = AD + 7
AD = 10 – 7 = 3 cm
Hence, AD = 3 cm.
