Answer» $\rule{300}2$ Your Answer: √6412= 80.07 So, the nearest SQUARE ROOT is 81 if we ADD something. Now, we know we have to obtain 81² by adding x in 6412 => 81² = 6412 + x => 6561 = 6412 + x => 6561 - 6412= x => 149 = x So, the number we have to add is 149 and the its square root is 81 Plz Mark it as brainliest. $\rule{300}2$

Your Answer:

√6412= 80.07

So, the nearest SQUARE ROOT is 81 if we ADD something.

Now, we know we have to obtain 81² by adding x in 6412

=> 81² = 6412 + x

=> 6561 = 6412 + x

Equation of the line passing through the points (14,7) (-36,-18),(4020),(2010) is

Answer»

Answer:

Y=0.5X

Step-by-step explanation:

equation of LINE from passing through GIVEN POINTS is.

Y=m×X+c

(14,7). (-36,-18)

m=slope of line

m=y2-y1/x2-x1

m=25/50

m=1/2

Y=0.5×X+c

now put value of any point of line in this equation.

7=0.5×14+c

c=0

732 : 1764 :: 912 : ? select the talented number by given alternative 1) 1444 , 2) 121, 3) 324, 4)1729

Answer»

Step-by-step explanation:

GIVEN 732 : 1764 :: 912 : ? select the talented number by given alternative 1) 1444 , 2) 121, 3) 324, 4)1729 

Given 732 : 1764 :: 912 : ? select the talented number
So we need to find the missing number in the given proportion.
Given 732 : 1764 : : 912 : x
Product of means = product of extremes.
Now 732 / 1764 = 912 / x
So 732 x = 912 x 1764
Or x = 912 x 1764 / 732
Or x = 2197.7

Show that the diagonals of a square are equal and bisect each other at right angles.

Answer»

Answer:

given ABCD is a square

prove AC = BD,OA=OC

Step-by-step explanation:

proof . in triangle BAD and CAD

AD =AD(COMMON)

AB = CO( sides of square )

angle C = angle A (each 90 DEGREE)

by SAS rule

triangle BAD is congruent to triangle

hence, BO=AC (by CPCT)

every square is parallelogram diagonal bisect each other

= OA = OC, OB=OD

in triangle ADB and triangle COB

AB= CB

OB=OB(COMMON)

OA =OC (PROVED ABOVE)

BY SSS RULE

triangle ABC is congruent to triangle COB

angle AOB +angle COB=180 DEGREE

angle AOB+angle AOB=180 DEGREE

twice of angle AOB =180 DEGREE

angle AOB= 180/2=90 DEGREE

THERE FORE, AOB=90 DEGREE

Answer» Given : The monthly deposit AMOUNT = P = Rs 400 The MATURITY value = A = Rs 8560 The rate of interest = R = 8% per annum To Find : The number of installments Solution : Let The number of installments = n ∵ Interest = P × $\dfrac{n \times ( n + 1)}{2}$ × $\dfrac{R \times T}{100}$ Or, = Rs 400 × $\dfrac{n \times ( n + 1)}{2}$ × $\dfrac{8 \times 1}{100 \times 12}$ Or, = 2.67 × $\dfrac{n \times ( n + 1)}{2}$ Again Maturity value = money deposit + Interest Or, A = Rs 400 × n + 2.67 × $\dfrac{n \times ( n + 1)}{2}$ Or, Rs 8560 = Rs 400 n + 2.67 × $\dfrac{n \times ( n + 1)}{2}$ Or, 2.67 × $\dfrac{n \times ( n + 1)}{2}$ = 8560 - 400 n Or, $\dfrac{n \times ( n + 1)}{2}$ = $\dfrac{8560}{2.67}$ - 400 n Or, $\dfrac{n \times ( n + 1)}{2}$ = 3205.9 - 400 n Or, n² + n = 6411.8 - 800 n Or, n² + 801 n - 6411.8 = 0 Solving this quadratic equation i.e n = $\dfrac{-801\pm \sqrt{(801)^{2}-4\times 1\times (-6411.8)}}{2\times 1}$ ∴ n = 7.9 ≈ 8 , - 808.9 Number of installment = n = 8 Hence, The number of installments that have to pay is 8 .

Jainil opens recurring deposit amount in the bank of rupees 400 per month how many installment does he have to pay to get a maturity of rupees 8560 if the bank pays the simple interest of 8% per annum

Answer»

Given :

The monthly deposit AMOUNT = P = Rs 400

The MATURITY value = A = Rs 8560

The rate of interest = R = 8% per annum

To Find :

The number of installments

Solution :

Let The number of installments = n

∵ Interest = P × $\dfrac{n \times ( n + 1)}{2}$ × $\dfrac{R \times T}{100}$

Or, = Rs 400 × $\dfrac{n \times ( n + 1)}{2}$ × $\dfrac{8 \times 1}{100 \times 12}$

Or, = 2.67 × $\dfrac{n \times ( n + 1)}{2}$

Again

Maturity value = money deposit + Interest

Or, A = Rs 400 × n + 2.67 × $\dfrac{n \times ( n + 1)}{2}$

Or, Rs 8560 = Rs 400 n + 2.67 × $\dfrac{n \times ( n + 1)}{2}$

Or, 2.67 × $\dfrac{n \times ( n + 1)}{2}$ = 8560 - 400 n

Or, $\dfrac{n \times ( n + 1)}{2}$ = $\dfrac{8560}{2.67}$ - 400 n

Or, $\dfrac{n \times ( n + 1)}{2}$ = 3205.9 - 400 n

Or, n² + n = 6411.8 - 800 n

Or, n² + 801 n - 6411.8 = 0

Solving this quadratic equation

i.e n = $\dfrac{-801\pm \sqrt{(801)^{2}-4\times 1\times (-6411.8)}}{2\times 1}$

∴ n = 7.9 ≈ 8 , - 808.9

Number of installment = n = 8

Hence, The number of installments that have to pay is 8 . Answer

48.	5x + 3y = 9 ……. (i)2x + 3y = 12 ……… (ii)
Answer» ANSWER : x = 3. and y = -2. Given : We have equation, 5x + 3y = 9. 2x -3y = 12. Solution : We have two equation, $\tt5x + 3y = 9. - - - (1)$ $\tt2x - 3y = 12. - - - (2)$ Let's apply Elimination method, on both Equation $\begin{tabular}{ 1-1 } 5x + 3y = 9. & \\ 2x -3y = 12. & \\ \cline{1-1} 7x = 21. & \\ \cline{1-1} \end{tabular}$ $\implies \tt x = \frac{21}{7}$ $\implies \tt x = 3.$ Now, Putting the VALUE of x in equation (2), We get. $\implies \tt 2x - 3y = 12.$ $\implies \tt 2(3)- 3y = 12.$ $\implies \tt 6- 3y = 12.$ $\implies \tt - 3y = 12 - 6$ $\implies \tt y = - \frac{12 - 6}{3}$ $\implies \tt y = - 2.$ $\rule{200}3$ Let's VERIFY : $\implies \tt5x + 3y = 9.$ $\implies \tt 5(3) + 3( - 2) = 9.$ $\implies \tt 15 - 6 = 9.$ $\implies \tt 9 = 9.$ Therefore, the value of x = 3 and y= -2.

48.

5x + 3y = 9 ……. (i)2x + 3y = 12 ……… (ii)

Answer»

ANSWER :

x = 3. and y = -2.

Given :

We have equation,

5x + 3y = 9.
2x -3y = 12.

Solution :

We have two equation,

$\tt5x + 3y = 9. - - - (1)$

$\tt2x - 3y = 12. - - - (2)$

Let's apply Elimination method, on both Equation

$\begin{tabular}{ 1-1 } 5x + 3y = 9. & \\ 2x -3y = 12. & \\ \cline{1-1} 7x = 21. & \\ \cline{1-1} \end{tabular}$

$\implies \tt x = \frac{21}{7}$

$\implies \tt x = 3.$

Now, Putting the VALUE of x in equation (2), We get.

$\implies \tt 2x - 3y = 12.$

$\implies \tt 2(3)- 3y = 12.$

$\implies \tt 6- 3y = 12.$

$\implies \tt - 3y = 12 - 6$

$\implies \tt y = - \frac{12 - 6}{3}$

$\implies \tt y = - 2.$

$\rule{200}3$

Let's VERIFY :

$\implies \tt5x + 3y = 9.$

$\implies \tt 5(3) + 3( - 2) = 9.$

$\implies \tt 15 - 6 = 9.$

$\implies \tt 9 = 9.$

Therefore, the value of x = 3 and y= -2.
