Step-by-step EXPLANATION:

(1) let's two ANGELS are X and Y

so by condition let take X. is GREATER and Y is smaller

so X = Y + 18--------------(1)

and both are supplementary

so, X+Y=180-----------------(2)

from eq. 1 and 2

Y+Y+18=180

2y = 180-18

2Y=162

Y=81°

X=81+18

=99°

Answer» ${\underline{{\text{Question}}}}$ The simple interest and compound interest on a certain sum of money is Rs 400 and Rs 410 respectively for 2 yrs. find principal and rate of interest? Step-by-step explanation: ${\underline{{\text{Given}}}}$ Simple Interest (I) = Rs 400 Compound Interest (C.I) = Rs 410 Time (t) = 2 yr ${\underline{{\text{To Find:}}}}$ Principal (P) Rate of interest (R) ${\underline{{\text{Solution:}}}}$ LET, the principal be Rs x and the rate of interest be y % per annum. $\text{So, Simple Interest} = \frac{Prt}{100} \\ \\ = \frac{x \times y \times 2}{100} \\ \\ = \frac{2xy}{100} .........(i)$ Again, $\text{Compound Interest}= P \{(1+\dfrac{r}{100})^{t} - 1 \} \\ \\ = x \{(1+\dfrac{y}{100})^{2} - 1 \} \\ \\ = x (1+\dfrac{y}{100} + 1 ) (1 + \frac{y}{100} - 1) \\ \\ \text{[Using} \: \: {a}^{2} - { b}^{2} = (a + b)(a - b)] \\ \\ = x(2 + \frac{y}{100} )( \frac{y}{100} ) \\ \\ = \frac{xy}{100} (2 + \frac{y}{100} ).......(<klux>II</klux>)$ Now, DIVIDING (ii) by (i) I get, $\frac{\frac{xy}{100} (2 + \frac{y}{100} )}{ \frac{2xy}{100} } = \frac{410}{400} \\ \\ \frac{ \cancel\frac{xy}{100} (2 + \frac{y}{100} )}{ \cancel\frac{2xy}{100} } = \frac{41 \cancel0}{40 \cancel0} \\ \\ \frac{(2 + \frac{y}{100} )}{2} = \frac{41}{40} \\ \\ 2 + \frac{y}{100} = 2 \times \frac{41}{40} \\ \\ \frac{y}{100} = \frac{82}{40} - 2 \\ \\ \frac{y}{100} = \frac{2}{40} \\ \\ \frac{y}{ \cancel{100}} = \frac{1}{ \cancel{20}} \\ \\ y = 5\%$ HENCE, the required rate of interest is 5% . So, $\frac{2xy}{100} = 400 \\ \\ \frac{ 2 \times 5 \times x}{100} = 400 \\ \\ \frac{10x}{100} = 400 \\ \\ x = 4000 \times 10 \\ \\ x = 4000$ Hence, the required Principal is Rs 4000. ${\underline{{\text{ Some Important Formula Of Interest }}}}$ $i)I = \dfrac{ P rt}{100}$ Where, I = Simple Interest P = Principal t = time r = rate of interest $ii)C.I = P \{(1+\dfrac{r}{100})^{t} - 1 \}$ Where, C.I = Compound Interest

Answer»

${\underline{{\text{Question}}}}$

The simple interest and compound interest on a certain sum of money is Rs 400 and Rs 410 respectively for 2 yrs. find principal and rate of interest?

Step-by-step explanation:

${\underline{{\text{Given}}}}$

Simple Interest (I) = Rs 400

Compound Interest (C.I) = Rs 410

Time (t) = 2 yr

${\underline{{\text{To Find:}}}}$

Principal (P)

Rate of interest (R)

${\underline{{\text{Solution:}}}}$

LET, the principal be Rs x and the rate of interest be y % per annum.

$\text{So, Simple Interest} = \frac{Prt}{100} \\ \\ = \frac{x \times y \times 2}{100} \\ \\ = \frac{2xy}{100} .........(i)$

Again,

$\text{Compound Interest}= P \{(1+\dfrac{r}{100})^{t} - 1 \} \\ \\ = x \{(1+\dfrac{y}{100})^{2} - 1 \} \\ \\ = x (1+\dfrac{y}{100} + 1 ) (1 + \frac{y}{100} - 1) \\ \\ \text{[Using} \: \: {a}^{2} - { b}^{2} = (a + b)(a - b)] \\ \\ = x(2 + \frac{y}{100} )( \frac{y}{100} ) \\ \\ = \frac{xy}{100} (2 + \frac{y}{100} ).......(<klux>II</klux>)$

Now, DIVIDING (ii) by (i) I get,

$\frac{\frac{xy}{100} (2 + \frac{y}{100} )}{ \frac{2xy}{100} } = \frac{410}{400} \\ \\ \frac{ \cancel\frac{xy}{100} (2 + \frac{y}{100} )}{ \cancel\frac{2xy}{100} } = \frac{41 \cancel0}{40 \cancel0} \\ \\ \frac{(2 + \frac{y}{100} )}{2} = \frac{41}{40} \\ \\ 2 + \frac{y}{100} = 2 \times \frac{41}{40} \\ \\ \frac{y}{100} = \frac{82}{40} - 2 \\ \\ \frac{y}{100} = \frac{2}{40} \\ \\ \frac{y}{ \cancel{100}} = \frac{1}{ \cancel{20}} \\ \\ y = 5\%$

HENCE, the required rate of interest is 5% .

So,

$\frac{2xy}{100} = 400 \\ \\ \frac{ 2 \times 5 \times x}{100} = 400 \\ \\ \frac{10x}{100} = 400 \\ \\ x = 4000 \times 10 \\ \\ x = 4000$

Hence, the required Principal is Rs 4000.

${\underline{{\text{ Some Important Formula Of Interest }}}}$

$i)I = \dfrac{ P rt}{100}$

Where, I = Simple Interest

P = Principal

t = time

r = rate of interest

$ii)C.I = P \{(1+\dfrac{r}{100})^{t} - 1 \}$

Where, C.I = Compound Interest

If one root of the quadic polynomial ax²-6x-6 is 4 , then find the value of a . Also find the sum of its zeros

Answer»

$\Large{\underline{\underline{\mathfrak{\bf{Question}}}}}$

If one root of the quadic polynomial ax²-6x-6 is 4 , then find the value of a . Also find the sum of its zeros ?

$\Large{\underline{\underline{\mathfrak{\bf{Solution}}}}}$

$\Large{\underline{\mathfrak{\bf{\red{Given}}}}}$

polynomial , ax² - 6x - 6 = 0
And, 4 is a zeroes of this equation

$\Large{\underline{\mathfrak{\bf{\red{Find}}}}}$

Value of a
Second zeroes of this equation .
Sum of zeroes

$\Large{\underline{\underline{\mathfrak{\bf{Explanation}}}}}$

We know,

If 4 is a zeroes of this equation .

so we can say that, this value of x exits of this equation.

Keep value of x = 4 in this equation,

➠ a.(4)² - 6.(4) - 6 = 0

➠ 16a - 24 - 6 = 0

➠ 16a = 30

➠ a = 30/16

➠ a = 15/8

Now , keep value of a = 15/8 in this equation

➠ (15/8)x² - 6x - 6 = 0

➠ 15x² - 48X - 48 = 0

➠ 5x² - 16x - 16 = 0 (New equation)

➠ 5x² - 20x + 4x - 16 = 0

➠ 5x (x - 4) + 4(x - 4 ) = 0

➠ (5x + 4)(x-4) = 0

➠ (5x + 4) = 0 Or, ( x -4) = 0

➠ 5x = -4 Or, x = 4

➠ x = -4/5 Or, x = 4

$\Large{\underline{\mathfrak{\bf{\red{Thus}}}}}$

Both zeroes of this equation is -4/5 and 4

Now,

➠ Sum of both zeroes = ( -4/5) + (4)

➠ Sum of both zeroes = (-4+20)/5

➠ Sum of both zeroes = 16/5

$\Large{\underline{\mathfrak{\bf{\orange{Verification}}}}}$

We know,

$\small\boxed{\sf{\green{\:Sum\:of\:zeroes\:=\:\dfrac{-(coefficient\:of\:x)}{(coefficient\:of\:x^2)}}}}$

$:\mapsto\sf{\:Sum\:of\:zeroes\:=\:\dfrac{-(-16)}{5}} \\ \\ :\mapsto\sf{\pink{\:Sum\:of\:zeroes\:=\:\dfrac{16}{5}}}$

That's proved

36.	Express -3/5 as a rational number with denominator
Answer» Answer: -3/5 = -12/20 Step-by-step explanation: GIVEN -3/5 EQUIVALENT rational no. with denominator equal to 20. Equivalent rational no. are rational no whose simplest form are equal. For example, -4/8 = -6/12 Denominator of given rational is 5 and denominator of equivalent rational no. is 20 & we know 20 is 4th multiple of 5 .i.e., 20 = 4 × 5 then, By multiplying & dividing the given rational no with 4 ,We get equivalent rational with denominator 20 -3 / 5 x 4/4 = -12 / 20 Therefore, -3/5 = -12 / 20 if you like my answer PLEASE support by giving THANKS

Express -3/5 as a rational number with denominator

Answer»

Answer:

-3/5 = -12/20

Step-by-step explanation:

GIVEN -3/5

EQUIVALENT rational no. with denominator equal to 20.

Equivalent rational no. are rational no whose simplest form are equal.

For example, -4/8 = -6/12

Denominator of given rational is 5 and denominator of equivalent rational no. is 20

& we know 20 is 4th multiple of 5 .i.e., 20 = 4 × 5

then,

By multiplying & dividing the given rational no with 4 ,We get equivalent rational with denominator 20

-3 / 5 x 4/4 = -12 / 20

Therefore, -3/5 = -12 / 20

What should be subtracted from 4 by 9 to get 5 by 72

Answer»

ANSWER: $X = \frac{3}{8}$

Step-by-step explanation:

Let the no. be X which is SUBTRACTED from 4/9

According to question,(we have the equation)

$\frac{4}{9} - X = \frac{5}{72}$

⇒ $\frac{4}{9} - \frac{5}{72} = X$

Now,taking the LCM we can solve the above equation

⇒ $\frac{(8*4)- 5}{72} =X$

⇒ $\frac{32 - 5}{72} = X$

⇒ $\frac{27}{72} = X$

DIVIDE the above equation to GET the exact value of X

⇒ $\frac{3}{8} = 0.375 = X$
