Answer» $\bf{\underline{Given}}:-$ The LENGTH and breadth of a rectangular park are in the ratio 8:5. A PATH,1.5 m wide, running all AROUND the outside of the park has an area of 594 m². To find :- The DIMENSIONS of the park Solution :- Let the length of the plot be 8x m and the breadth of the plot be 5x m Area of the park = l × b Area of the park = 8x × 5x Area of the park = 40x² m² Now, Length of the park including the path = (8x + 3) Breadth of the park including the path = (5x + 3) Then, Area of park including the path = (8x + 3)(5x + 3) Area of park including the path = 8x(5x + 3) + 3(5x + 3) Area of the park including the path = 40x² + 24x + 15x + 9 Area of park including the path = 40x² + 39x + 9 Area of the path = Area of park including the path - Area of the park Area of the path = 40x² + 39x + 9 - 40x² Area of the path = 39x + 9 According to the question, ⤇ 39x + 9 = 594 ⤇ 39x = 594 - 9 ⤇ 39x = 585 ⤇ x = 585/39 ⤇ x = 15 Hence, Length = 8x = 8 × 15 = 120 m breadth = 5x = 5 × 15 = 75 m

The length and the breadth of a rectangular park are in the ratio 8:5. A path, 1.5 m wide, running all around the outside of the park has an area of 594 m square. Find the dimensions of the park.

Answer»

$\bf{\underline{Given}}:-$

The LENGTH and breadth of a rectangular park are in the ratio 8:5.

A PATH,1.5 m wide, running all AROUND the outside of the park has an area of 594 m².

To find :-

The DIMENSIONS of the park

Solution :-

Let the length of the plot be 8x m

and the breadth of the plot be 5x m

Area of the park = l × b

Area of the park = 8x × 5x

Area of the park = 40x² m²

Now,

Length of the park including the path = (8x + 3)

Breadth of the park including the path = (5x + 3)

Then,

Area of park including the path = (8x + 3)(5x + 3)

Area of park including the path = 8x(5x + 3) + 3(5x + 3)

Area of the park including the path = 40x² + 24x + 15x + 9

Area of park including the path = 40x² + 39x + 9

Area of the path = Area of park including the path - Area of the park

Area of the path = 40x² + 39x + 9 - 40x²

Area of the path = 39x + 9

According to the question,

⤇ 39x + 9 = 594

⤇ 39x = 594 - 9

⤇ 39x = 585

⤇ x = 585/39

⤇ x = 15

Hence,

Length = 8x = 8 × 15 = 120 m

breadth = 5x = 5 × 15 = 75 m

16762.	7/x-15/y=9 11/x-8/y=-17 by simultaneously
Answer» Answer: Step-by-step explanation: X + y =5 and 2x –3y = 4 By elimination method x + y =5 ... (i) 2x –3y = 4 ... (II) Multiplying equation (i) by (ii), we get 2x + 2y = 10 ... (iii) 2x –3y = 4 ... (ii) Subtracting equation (ii) from equation (iii), we get 5y = 6 y = 6/5 Putting the value in equation (i), we get x = 5 - (6/5) = 19/5 Hence, x = 19/5 and y = 6/5 By substitution methodx + y = 5 ... (i) Subtracting y both side, we get x = 5 - y ... (iv) Putting the value of x in equation (ii) we get 2(5 – y) – 3y = 4 -5y = - 6 y = -6/-5 = 6/5 Putting the value of y in equation (iv) we get x = 5 – 6/5 x = 19/5 Hence, x = 19/5 and y = 6/5 again (ii) 3x + 4y = 10 and 2x – 2y = 2 By elimination method 3x + 4y = 10 .... (i) 2x – 2y = 2 ... (ii) Multiplying equation (ii) by 2, we get 4x – 4y = 4 ... (iii) 3x + 4y = 10 ... (i) Adding equation (i) and (iii), we get 7x + 0 = 14 Dividing both side by 7, we get x = 14/7 = 2 Putting in equation (i), we get 3x + 4y = 10 3(2) + 4y = 10 6 + 4y = 10 4y = 10 – 6 4y = 4 y = 4/4 = 1 Hence, answer is x = 2, y = 1

16762.

7/x-15/y=9 11/x-8/y=-17 by simultaneously

Answer»

Answer:

Step-by-step explanation:

X + y =5 and 2x –3y = 4

By elimination method

x + y =5 ... (i)

2x –3y = 4 ... (II)

Multiplying equation (i) by (ii), we get

2x + 2y = 10 ... (iii)

2x –3y = 4 ... (ii)

Subtracting equation (ii) from equation (iii), we get

5y = 6

y = 6/5

Putting the value in equation (i), we get

x = 5 - (6/5) = 19/5

Hence, x = 19/5 and y = 6/5

By substitution methodx + y = 5 ... (i)

Subtracting y both side, we get

x = 5 - y ... (iv)

Putting the value of x in equation (ii) we get

2(5 – y) – 3y = 4

-5y = - 6

y = -6/-5 = 6/5

Putting the value of y in equation (iv) we get

x = 5 – 6/5

x = 19/5

Hence, x = 19/5 and y = 6/5 again

(ii) 3x + 4y = 10 and 2x – 2y = 2

By elimination method

3x + 4y = 10 .... (i)

2x – 2y = 2 ... (ii)

Multiplying equation (ii) by 2, we get

4x – 4y = 4 ... (iii)

3x + 4y = 10 ... (i)

Adding equation (i) and (iii), we get

7x + 0 = 14

Dividing both side by 7, we get

x = 14/7 = 2

Putting in equation (i), we get

3x + 4y = 10

3(2) + 4y = 10

6 + 4y = 10

4y = 10 – 6

4y = 4

y = 4/4 = 1

Hence, answer is x = 2, y = 1

Step-by-step explanation:

$\huge\underline\mathfrak{Answer}$

$( { \frac{2}{7} })^{ - <klux>5</klux>} \times ({ \frac{2}{7} })^{m} = ({ \frac{2}{7} })^{6}$

We know that a^m × a^n = a^m+n

So,

$( { \frac{2}{7} })^{ - 5 + m} = ({ \frac{2}{7} })^{6}$

If the bases are EQUAL,equate the POWERS

- 5 + m = 6

m = 6+5

m = 11

A quadratic sequence is a sequence of numbers in which the second difference between any two consecutive terms is constant (definition TAKEN from here). The difference of consecutive terms in your sequence forms an arithmetic progression 2,3,4,5,… with common difference of 1. Since the sequence is a quadratic sequence, the nth term of the sequence is given by a quadratic polynomial: Tn=an2+bn+c As stated by Siddhant in his answer, you could just plug in n as 1,2 and 3 to get three equations in three VARIABLES and get the values of a,b and c. However, we could use a rather generalized formula for getting the EQUATION for nth term of the sequence (you should try deriving this formula): Tn=(d02)n2+(d−3⋅d02)n+(a+d0−d) where a is the first term of the sequence, d=T2−T1 i.e. difference between first two terms of the sequence and d0 is the second difference between any two consecutive terms of the sequence. In your case, a=1, d=2 and d0=1. Plugging in these values in the equation yields Tn=12n2+12n For finding the sum: ∑i=1nTi =∑i=1n(12i2+12i) You can solve this using the already known summations ∑ni=1i2 and ∑ni=

Step-by-step explanation:

The sequence that you are talking about is a quadratic sequence. A quadratic sequence is a sequence of numbers in which the second difference between any two consecutive terms is constant (definition TAKEN from here).

The difference of consecutive terms in your sequence forms an arithmetic progression 2,3,4,5,… with common difference of 1. Since the sequence is a quadratic sequence, the nth term of the sequence is given by a quadratic polynomial:

Tn=an2+bn+c

As stated by Siddhant in his answer, you could just plug in n as 1,2 and 3 to get three equations in three VARIABLES and get the values of a,b and c. However, we could use a rather generalized formula for getting the EQUATION for nth term of the sequence (you should try deriving this formula):

Tn=(d02)n2+(d−3⋅d02)n+(a+d0−d)

where a is the first term of the sequence, d=T2−T1 i.e. difference between first two terms of the sequence and d0 is the second difference between any two consecutive terms of the sequence. In your case, a=1, d=2 and d0=1. Plugging in these values in the equation yields

Tn=12n2+12n

For finding the sum:

∑i=1nTi

=∑i=1n(12i2+12i)

You can solve this using the already known summations ∑ni=1i2 and ∑ni=
