Answer» Required run-rate is 8.375 Correct answer: OPTION d = 8.375 Step-by-step explanation : Run rate in first 10 overs is 4.5 Then total RUNS in first 10 overs is (10 * 4.5) = 45 In a game of 50 overs, to reach the target of 380 runs, i.e., the remaining (380 - 45) = 335 runs to obtain in (50 - 10) = 40 overs The required run-rate will be = 335/40 = 8.375 Thus option d = 8.375 is correct.

Answer»

Required run-rate is 8.375

Correct answer: OPTION d = 8.375

Step-by-step explanation :

Run rate in first 10 overs is 4.5

Then total RUNS in first 10 overs is (10 * 4.5) = 45

In a game of 50 overs, to reach the target of 380 runs, i.e., the remaining (380 - 45) = 335 runs to obtain in (50 - 10) = 40 overs

The required run-rate will be

= 335/40 = 8.375

Thus option d = 8.375 is correct.

a cottage industry produces a certain number of patteries in a day . it was found that the cost of production of each article ₹5 more than twice the number of patteries produced in a day . if the cost of production on that day was ₹168, find the number of potteries produced.

Answer»

Answer:

no. of potteries is 8

Step-by-step EXPLANATION:

no. of potteries be x

cost of total PRODUCTION of a day = rs 168

cost of each potteries = rs 2x + 5

A/Q

(no. of article)(cost of each) = total cost

(x)(2x + 5) = 168

2x^2 + 5X = 168

2x^2 + 5x - 168 = 0

2x^2 + 21X - 16x - `168 = 0

x( 2x + 21) - 8 (2x + 21) = 0

(x -8)(2x + 21) = 0

now, x - 8 = 0 and 2x + 21 = 0

x = 8 and x = -21/2

since no. of potteries can not be -ve

therefore x = 8 and no. of potteries is 8

Answer» Answer: In elementary geometry, a polygon (/ˈpɒlɪɡɒn/) is a plane figure that is described by a finite NUMBER of straight line segments connected to form a closed polygonal chain or polygonal CIRCUIT. The solid plane region, the bounding circuit, or the two together, may be called a polygon. The segments of a polygonal circuit are called its EDGES or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners. The INTERIOR of a solid polygon is sometimes called its body. An N-gon is a polygon with n sides; for example, a triangle is a 3-gon.

Answer» Answer: Step-by-step EXPLANATION: c = π r L, where r = radius of the base of the cone and L = slanting length of the cone => c = π r * √(r^2 + H^2) => c^2 = (π r)^2 * (r^2 + h^2) ... (1) VOLUME of the cone, V = (1/3) π r^2 h => r^2 = (3V) / (π h) Plugging this value of r^2 in (1), c^2 = (π)^2 * (3V) / (π h) * [(3V) / (π h) + h^2] => c^2 = (9V^2) / h^2 + 3πVh => c^2h^2 = 9V^2 + 3πVh^3 => 3πvh^3 - c^2h^2 + 9v^2 = 0.

19521.

C2=3πvh3+9v2/h2

Answer»

Answer:

Step-by-step EXPLANATION:

c = π r L, where r = radius of the base of the cone and L = slanting length of the cone

=> c = π r * √(r^2 + H^2)

=> c^2 = (π r)^2 * (r^2 + h^2) ... (1)

VOLUME of the cone,

V = (1/3) π r^2 h

=> r^2 = (3V) / (π h)

Plugging this value of r^2 in (1),

c^2 = (π)^2 * (3V) / (π h) * [(3V) / (π h) + h^2]

=> c^2 = (9V^2) / h^2 + 3πVh

=> c^2h^2 = 9V^2 + 3πVh^3

=> 3πvh^3 - c^2h^2 + 9v^2 = 0.

let l Be a line and PB are point not on l through P draw a line parallel to Al now joint P2 any point on elss choose any other. Are on am through our draw a line parallel to PQ let this meet l at as what shape do the two sets of parallel line and closed

Answer»

Answer:

In △ABC AB=AC

⇒∠B=∠C (Angles OPPOSITE to equal sides are equal)

Now using angle SUM property

∠A+∠B+∠C=180

∘

⇒80

∘

+∠C+∠C=180

∘

⇒2∠C=180

∘

−80

∘

⇒∠C=

2

100

∘

=50

∘

now ∠C+∠x=180

∘

(Angles made on straight LINE (AC) are SUPPLEMENTARY)

⇒50

∘

+∠x=180

∘

⇒∠x=180

∘

−50

∘

=130
