5901.	Ratinalise the denominator3/4-√7
Answer» ANSWER: There are multiple ways to go about doing this. The first method that I thought of is to start by looking at the fraction like so: 3–√−2(2+3–√)−7–√ From this, it makes SENSE to try multiplying the NUMERATOR and the denominator by (2+3–√)+7–√ , giving 3–√−2(2+3–√)−7–√×(2+3–√)+7–√(2+3–√)+7–√=23–√+3+21−−√−4−23–√−27–√(2+3–√)2−7=−1−27–√+21−−√43–√.

Ratinalise the denominator3/4-√7

Answer»

There are multiple ways to go about doing this. The first method that I thought of is to start by looking at the fraction like so:

3–√−2(2+3–√)−7–√

From this, it makes SENSE to try multiplying the NUMERATOR and the denominator by (2+3–√)+7–√ , giving

3–√−2(2+3–√)−7–√×(2+3–√)+7–√(2+3–√)+7–√=23–√+3+21−−√−4−23–√−27–√(2+3–√)2−7=−1−27–√+21−−√43–√.

5904.	Answer this fast i will mark you as brainliest
Answer» Step-by-step explanation: we all know that SUM of interior angles of QUADRILATERAL is 360 degrees. now the given EQUATION is: 4X,(5x+20),(6x+8),(7x+2). so what we gave to do is equal the given equation with 360. we get, 4x+5x+20+6x+8+7x+2=360 22 X+30=360 22 X=360-30 =330 X=330/22 (X=15) so, 4x= 4x15 =60 5x+20=75+20=95 6x+8=90+8=98 7x+2=105+2=107. so,add these angles 60+95+98+107=360 so,the required angles for quadrilateral are 60,95,98,107.

Answer this fast i will mark you as brainliest

Answer»

Step-by-step explanation:

we all know that SUM of interior angles of QUADRILATERAL is 360 degrees.

now the given EQUATION is:

4X,(5x+20),(6x+8),(7x+2).

so what we gave to do is equal the given equation with 360.

we get, 4x+5x+20+6x+8+7x+2=360

22 X+30=360

22 X=360-30

=330

X=330/22

(X=15)

so, 4x= 4x15 =60

5x+20=75+20=95

6x+8=90+8=98

7x+2=105+2=107.

so,add these angles 60+95+98+107=360

so,the required angles for quadrilateral are 60,95,98,107.

The difference in the interests on the amounts in the third and in the second year is Rs 12,100. What amount has Mayank deposited?1) Rs 1.10 lakhs 2) Rs 99,000 3) Rs 1 lakh 4) Rs 90,000 5) Rs. 10 lakhs
Answer» Rs 1 lakh Step by step Interest for TWO years will be 10 + 10 + 10 x 10 / 100 = 21% So interest for 3 years will be 21 + 10 + 21 x 10/100 = 33.1$ So 33.1-21 = 12.1% of a = 12,100 0.121 x a = 12,100 A = 12,100 / 0.121 A = Rs 1,00,000 Mayank has deposited Rs one lakh

1) 44. Mayank has deposited a certain amount in the bank to earn compound inte the rate of 10% per annum. The difference in the interests on the amounts in the third and in the second year is Rs 12,100. What amount has Mayank deposited?1) Rs 1.10 lakhs 2) Rs 99,000 3) Rs 1 lakh 4) Rs 90,000 5) Rs. 10 lakhs

Answer»

Rs 1 lakh

Step by step

Interest for TWO years will be 10 + 10 + 10 x 10 / 100 = 21%

So interest for 3 years will be 21 + 10 + 21 x 10/100 = 33.1$

So 33.1-21 = 12.1% of a = 12,100

0.121 x a = 12,100

A = 12,100 / 0.121

A = Rs 1,00,000

Mayank has deposited Rs one lakh

ANSWER:

Denominator = 2^3 × 5^4

Explanation: The denominator can be WRITTEN in form of 2^n × 5^m by prime factorisation.

N.B.:-

min(n, m) is the number of decimal places after which it will terminate.

For example, in 251/5000, 5000 = 2^3 × 5^4. So, min(3, 4) = 3. So, after three decimal places, it will terminate.

In CASE when denominator is not in form of 2^a × 5^b, the number is not terminating.

6find the value of (a+B) & (aß) forthe following equn. x2 - 112 +33 = 0

Answer»

ANSWER:

$a +b =-111\\ \\\alpha \beta =33$

Step-by-step EXPLANATION:

For the QUADRATIC equation of the form -

$ax^{2} +bx+c=0$

Compare with the equation with $x^{2} -112x+33=0$ , we get -

$a=1$ , $b=-112$ and $c=33$ .

Then the value of -

$a+b=-112+1$

$=-111$

Let the ROOTS be $\alpha$ and $\beta$ .

PRODUCT of roots $=\frac{c}{a}$

$=\frac{33}{1}$

$\alpha \beta =33$

Find the equation of the straight line passing through the point (-2, 1) and perpendicular to the line 3x+5y+2=0.

Answer»

EXPLANATION.

Equation of STRAIGHT lines.

Passing through POINT = (-2,1).

Perpendicular to the line : 3X + 5y + 2 = 0.

As we know that,

SLOPE of the perpendicular line = b/a.

Slope of the line : 3x + 5y + 2 = 0 is 5/3.

⇒ Slope = m = 5/3.

Equation of straight line.

⇒ (y - y₁) = m(x - x₁).

Put the values in the equation, we get.

⇒ (y - 1) = 5/3(x - (-2)).

⇒ (y - 1) = 5/3(x + 2).

⇒ 3(y - 1) = 5(x + 2).

⇒ 3y - 3 = 5X + 10.

⇒ 5x + 10 - 3y + 3 = 0.

⇒ 5x - 3y + 13 = 0.

MORE INFORMATION.

Slope of line.

(1) = m = tanθ, where θ is the acute angle made by a line with the positive direction of x axis in anticlockwise.

(2) = The slope of a line joining two points (x₁, y₁) and (x₂, y₂) is given by,

m = (y₂ - y₁)/(x₂ - x₁).

1 / 8 + 5root 2 rationalise the denominator

Answer»

Aim:-

To rationalise the DENOMINATOR of $\frac{1}{8+5\sqrt{2} }$

Procedure of solving:-

In ORDER to rationalise the denominator, we NEED to MULTIPLY the GIVEN fraction by $\frac{8-5\sqrt{2} }{8-5\sqrt{2}}$ .
After rationalising the denominator, we can find the value of the result.

Solution:-

On rationalising $\frac{1}{8+5\sqrt{2} }$ ,

$\frac{1}{8+5\sqrt{2} }\times\frac{8-5\sqrt{2} }{8-5\sqrt{2}}$

$=\frac{1(8-5\sqrt{2}) }{(8+5\sqrt{2})(8-5\sqrt{2} ) }$

⇒ $\frac{8-5\sqrt{2} }{(8)^2-(5\sqrt{2})^2 }$ $($ ∵ $(a+b)(a-b)=a^2-b^2)$

⇒ $\frac{8-5\sqrt{2} }{64-50 }$

⇒ $\frac{8-5\sqrt{2} }{14 }$

Conclusion:-

∴ $\boxed{\frac{1}{8+5\sqrt{2} }=\frac{8-5\sqrt{2} }{14}}$
