In a rational the denominator of a number is 9 more than its numerator . If the rational number is added with 5 then the sum is equal to 51/10 . Find the rational number​

Answer»

Answer:

1/9

Step-by-step explanation:

LET the NUMERATOR be x

so denominator=x+9

x/x+9 + 5 = 51/10

=>x/x+9= 51/10 -5

=>x/x+9=51-50/10

=>10x = x+9

=>10x-x=9

=>9x=9

x= 1

hence, numerator= 1

denominator = 10

Answer»

Answer:

72

Step-by-step explanation:

Solve this USING (a+b)^2=a^2+b^2+2ab

Let a be 3X

Let b be 2y

(3x+2y)^2=(3x) ^2+(2y) ^2+2*3x*2y

12^2=9x^2+4y^2+12*6

Find the smallest number by which 1100 must be multiplied so that the productbecomes a perfect square. Also, find the square root of the perfect squareobtained3. By what smallest number must 180 be multiplied so that it becomes a perfectsquare? Also, find the square root of the number so obtained.​

Answer»

ANSWER:

11 sqrt = 110

Step-by-step EXPLANATION:

FIRST the prime factorisation of 1100 is done

then 11 will be left over which we have to MULTIPLY with 1100

then it will be 1100 ×11=12100

now the sqrt of 12100 is 110 (answer)

3.ans = 5 sqrt = 30

again the prime factorisation is done

and 5 will be left over

we have to multiply 180 by 5

180×5=900

the sqrt of 900 is 30(answer)

(a+3b+2c+6d)(a-3b-2c+6d)=(a+3b-2c-6d)(a-3b+2c-6d), prove that a:b::c:d​

Answer»

LHS :-

Here, a=(a+3b+2c+6d)

B=(a-3b-2c+6d)

So, a:b=(a+3b+2c+6d):(a-3b-2c+6d)

RHS :-

Here, C=(a+3b-2c-6d)

d=(a-3b+2c-6d)

So, c:d=(a+3b-2c-6d):(a-3b+2c-6d)

LHS=RHS, so ,a:b::c:d=(a+3b+2c+6d):(a-3b-2c+6d)::(a+3b-2c-6d):(a-3b+2c-6d)

Find the smallest number by which 1100 must be multiplied so that the productbecomes a perfect square. Also, find the square root of the perfect square soobtained.By what smallest number must 180 be multiplied so that it becomes a perfectsquare? Also, find the square root of the number so obtained.​

Answer»

Answer:

1100, 30.

Step-by-step explanation:

1100 = 11 * 5 * 2.

Here, every prime factor appears only once. Hence to make it a PERFECT SQUARE, it must be multiplied by 1100 (11 * 5 * 2) itself. It GIVES the square root as 1100.

180 = 3 * 3 * 2 * 2 * 5.

Here, the only prime factor that doesn't form a PAIR is 5. hence, 180 must be multiplied by 5 to make it a perfect square. The square root thus obtained WOULD be 3 * 2 * 5 = 30.

Prove that area of equilateral triangle is root 3 by 2 into side square

Answer»

Step-by-step explanation:

Step 1: Since all the 3 sides of the triangle are same,

AB = BC = CA = a

Step 2: FIND the altitude of the △ABC.  

Draw a perpendicular from point A to base BC, AD ⊥ BC

By using Pythagoras theorem

In △ ADC

h2 = AC2 - DC2

= a2 - (a2)2 [Because, DC = a2 ]

= a2 - a24

h = 3√a2

Step 3: We know that, Area of a triangle = 12 * Base * HEIGHT

= 12 * a * 3√a2

= 3√4a2

The area of a equilateral triangle = 3√4a2.

A sum of Rs 800 is in denomination of Rs 10 and Rs 20. If the total number of notes are 50.Find the number of notes of each types.

Answer»

ANSWER:

Step-by-step explanation:

Let's call RS. 10 x and Rs. 20 y:

x+y= 50  

If we subtract y from both sides we get:

x= 50-y

It makes sense, right? If I take the Rs. 20 notes out of the total of 50 notes, then I am left with just the Rs. 10 notes. So REMEMBER this value of x, we will use it in the next equation:

10x+20y= 800 Now substitute for x:

10(50-y)+20y= 800

500-10y+20y= 800 Subtract -10y+20y on left and subtract 500 on both sides:

 

 

10y= 300

y= 30 You have 30 notes of 20 Rs. and:

50-30= 20 notes of 10 Rs.

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

Proof:

30(20)= 600

20(10)= 200

Total..: 800 We have the correct answer
