Let speed of boat in still water be x km/h and speed of stream be y km/h.

Speed upstream= (x - y) km/h

Speed downstream= (x + y) km/h

On subtracting, we get,

On solving, we get,

Speed of boat in still water = 8 km/h

And, Speed of stream = 3 km/h

Euclid division lemma:-

a=bq+r

First find the HCF of 693 and 567,

693=567(1)+126

567=126(4)+63

126=63(2)+0

HCF of 693 and 567 is 63.

Now find the HCF of 63 and 441,

441=63(7)+0

The HCF of 63 and 441 is 63.

Therefore, the HCF of 441,567 and 693 is 63.

Q: Use Euclid's division lemma to show that the cube of any positive integer is of the form 9m,9m+1 or 9m+8

Let be any positive integer. Then, it is of the form 3or, 3+ 1 or, 3+ 2.

So, we have the following cases :

 

Case I : When = 3q.

then, x3 = (3q)3 = 27q3 = 9 (3q3) = 9m, where = 3q3.

 

Case II : When = 3+ 1

then, x3 = (3+ 1)3

= 27q3 + 27q2 + 9+ 1

= 9 (3q2 + 3+ 1) + 1

= 9+ 1, where (3q2 + 3+ 1)

 

Case III. When = 3+ 2

then, x3 = (3+ 2)3

= 27 q3 + 54q2 + 36+ 8

= 9(3q2 + 6+ 4) + 8

= 9 + 8, where (3q2 + 6+ 4)

Hence, xis either of the form 9 or 9 + 1 or, 9 + 8.

Answer:

Step-by-step explanation:

we have to find the 5 irrational number which are lying between 4 and 5 in radical form

Irrational numbers are those real numbers that cannot be written as a simple fraction. These are non-terminating and non-repeating.

All the above five numbers are non-terminating and non-repeating.

Total pens=1001
Total pencils=910
we need to find maximum no.of students among whom 1001 pens and 910 pencils can be distributed in such a way that each students get same no.of pens and pencils.
Then we need to find HCF of 1001 and 910
Prime factorization of,
1001=7×11×13
910=2×5×7×13
HCF=product of commom prime factor of least power
HCF=7×13=91
Here HCF of 1001 and 910 is 91.

Hence among 91 students 1001 pens and 910 pencils can be distributed such that each student get same no.of pens and pencils.

Let’s assume the two numbers be x and y. And also assume that x is greater than or equal to y. 

So as per the question, we can write the sum of the two numbers as 

x + y = 1000 ……….. (i) 

Again it’s given that, the difference between the squares of the two numbers, thus writing it 

x2 – y2 = 256000

⇒ (x + y) (x – y) = 256000

⇒ 1000(x - y) = 256000 

⇒ x – y = 256000/1000 

⇒ x – y = 256 ………….. (ii) 

By solving (i) and (ii), we can find the two numbers 

On adding the equations (i) and (ii), we get; 

(x + y) + (x - y) = 1000 + 256 

⇒ x + y + x – y =1256 

⇒ 2x = 1256 

⇒ x = 1256/ 2 

⇒ x = 628 

Now, putting the value of x in equation (i), we get 

628 + y =1000 

⇒ y = 1000 – 628 

⇒ y = 372 

Hence, the two required numbers are 628 and 372.

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.
