\bold{\boxed{ Sn =  \frac{n}{2} (2a + (n - 1)d}}

=  > sp =  \frac{p}{2} (2a + (p - 1)d

=  > sq =  \frac{q}{2} (2a + (q - 1)d

\bold{\red{sp = sq}}

=  >  \frac{p}{2} (2a + (p - 1)d =  \frac{q}{2} (2a + (q - 1)d

=  > p(2a + (p - 1)d =  \frac{2 \times q}{2} (2a + (q - 1)d

=  >  p(2a + (p - 1)d) = q(2a + (q - 1)d)

=  > 2ap + pd(p - 1) = 2aq + qd(q - 1)

=  > 2ap - 2aq = qd(q - 1) - pd(p - 1)

=  > 2a(p - q) = d[(q - 1)q - (p - 1)p]

=  > 2a(p - q) = d( {q}^{2}  - q - ( {p}^{2}  - p)

=  > 2a(p - q) = d( {q}^{2}  - q -  {p}^{2}  + p)

=  > 2a(p - q) = d( {q}^{2}  -  {p}^{2}  + p - q)

=  > 2a(p - q) = -  d( -  {q}^{2}  +  {p}^{2}  - p + q)

=  > 2a(p - q) =  - d( {p}^{2}  -  {q}^{2}  - (p - q))

=  > 2a(p - q) =  - d[(p - q)(p + q) - (p - q)]

=  > 2a(p - q) =  - d[(p - q)(p + q) - (p - q) \times 1]

Taking (p-q) common from R.H.S

\bold{=  > (p - q)[2a + d(p + q - 1)d] = 0}

=  > p - q = 0

\bold{ =  > p = 0}

2a + d(p + q - 1) = 0

Now applying sum formula:

\bold{ =  > sn =  \frac{n}{2} [2a + (n - 1)d]}

\bold{ =  > s(p + q) =  \frac{p + q}{2} [2a + (p + q - 1)d]}

\bold{=  >  \frac{p + q}{2}  \times 0}

= 0

THEREFORE,the sum of the first (p + q) terms is 0.

Two places are 5 cm apart in a map with the scale1:500000. Find the actual ground distance between the places

Answer»

Answer:

a) Imagine we have MEASURED a distance as 3 cm on this map, and we want to find out how far this is in real life.

To work out the distance in real life, we need to multiply this length by 50000.

This gives 3 cm × 50000 = 150000 cm which is 1500 m or 1.5 km.

Alternatively, we could have just REMEMBERED that each 1 cm on the map is 0.5 km in real life.

Hence, 3 cm on the map must be 3 × 0.5 km = 1.5 km in real life.

(b) Now imagine we want to walk 4.5 km in real life, and we need to find out how far this is on the map.

To work out the distance on the map, we need to divide this length by 50000.

4.5 km = 4500 m = 450000 cm. Dividing 450000 cm by 50000 gives a distance on the map of 9 cm.

Alternatively, we could have just remembered that each 0.5 km in real life is 1 cm on the map.

If we divide 4.5 km by 0.5 km we get 9, so the distance on the map must be 9 cm.

The great Nature has intended us to earn our BREAD in the sweat of our brow. Every one, therefore, who idles away a single MINUTE becomes to that EXTENT a burden upon his neighbours, and to do so is to commit a breach of the very first lesson of AHIMSA. Ahimsa is nothing if not a well-balance, exquisite CONSIDERATION for one's neighbour, and an idle man is wanting in that elementary consideration. (YI, 11-4-1929, p. 144-15)

Find the cost of levelling a playground 51m long and 40m wide at rupees 35 per square metre. Also, find the cost of fencing it at rupees 50 per metre

Answer»

Answer:

Area of playground = (51×40) m² = 2040 m²

COST of levelling per m² = Rs.35

TOTAL cost of levelling = Rs.(35×2040) = Rs.71400

Perimeter of playground = 2(51+40) = 2(91) m = 182 m

Cost of fencing per metre = Rs.50

Total cost of fencing = Rs.(50×182) = Rs.9100

Ratio between the lateral area and base area of a cuboid will be[{( )}]Best answer will instantly marked as brainliest☺☺​

Answer»

The ratio between the LATERAL surface AREA and base area of cuboid is 4 : 1

Explanation:-

Let 'a' be the side length of a cube

Lateral surface area is 4a^{2}a

2

And base area = a^{2}a

2

To FIND the ratio between the lateral surface area and base area

\FRAC{lateral surface area}{lateral surface area}=\frac{4a^{2}}{a^{2}}

lateralsurfacearea

lateralsurfacearea

= 4

a

\frac{lateral surface area}{lateral surface area}=\frac{4}{1}

Therefore,ratio between the lateral surface area and base area of cuboid is 4 : 1

What is the total cost of tiling the yard atthe rate of Rs. 50 per square feet.​

Answer»

Step-by-step explanation:

so let edges be

6x ,5x,5x

now perimeter is = 64 feet

= 6x+5x+5x = 64

= 16x = 64

x= 4

so

6x= 24 ,5x= 20, 5x= 20

now AREA can be FOUND by heron's formula

which SAYS

s = perimeter/2 = 64/2 = 32 feet

and area

_/[ 32×(32-24)×(32-20)×(32-20)]

_/[32×8×12×12]

12_/(256)

12×16 = 192 per square feet

rate of tilling

192×50 = 9600 rs answer

Sum of first n terms of two different a.p.s are in ratio(3n+13)(7n-13) find the ratio 5th terms.​

Answer»

GIVEN :-

  • Sum of n terms of two different APs are in the ratio 3n + 13 : 7n - 13

To Find :-

  • Ratio of 5th terms.

Solution :-

Given us the sum of n terms of two different APs as,

⇒ S₁ / S₂ = (5n + 13) / (7N - 13)

Let the FIRST term and the COMMON difference of the two APs be a, a₂ and d, d₂ respectively.

Also, We know

⇒ Sum of n terms of an AP = n / 2 { 2a + (n - 1)d }

So,

⇒ [ n/2 { 2a + (n - 1)d } ] / [ n/2 { 2a₂ + (n - 1)d₂ ] = (5n + 13) / (7n - 13)

⇒ { 2a + (n - 1)d } / { 2a₂ + (n - 1)d₂ } = (5n + 13) / (7n - 13)

So, Here we have to substitute a value of n for which the EQUATION becomes the ratio of the 5th elements of the APs.

n = 8

⇒ { 2a + (9 - 1)d } / { 2a₂ + (9 - 1)d₂ } = (5×9 + 13) / (7×9 - 13)

⇒ a + 4d / a₂ + 4d₂ = 58 / 50

⇒ a₄ / a’₄ = 29 / 25

Hence,

The ratio of their fifth terms will be 29 : 25.
