cost of levelling the ground at the rate of rupees 7 per sqm was rupees 32, 340 if 500 rotations of a road roller of length 2.1 m were needed them find the diameter of the roller used

Answer»

Total cost for levelling = 32,340 rs

Rate of levelling = 7 rs / m²

Are LEVELLED = Total cost for levelling / Rate of levelling

= 32340 / 7 = 4620 m²

h = 2.1 m

Area levelled = area covered by ROAD roller in 500 rotations

4620 = 500 x 2πrh

4620 = 500 x 2 x 22/7 x r x 2.1

4620 x 7 / (500 x 22 x 2 x 2.1) = r

r = 7 / (10 x 3)

d = 14 / (10 x 3)

d = 0.47 m (APPROX) : Ans

Answer» One day's work of A, B and C = (1/24 + 1/30 + 1/40) = 1/10. C leaves 4 days before completion of the work, which means only A and B work during the last 4 days. Work done by A and B TOGETHER in the last 4 days = 4 (1/24 + 1/30) = 3/10. Remaining Work = 7/10, which was done by A,B and C in the initial number of days. Number of days REQUIRED for this initial work = 7 days. THUS, the total numbers of days required = 4 + 7 = 11 days.

A, B and C can do a piece of work in 24, 30 and 40 days respectively. They startthe work together but Cleaves 4 days before the completion of the work. In howmany days is the work done?

Answer»

One day's work of A, B and C = (1/24 + 1/30 + 1/40) = 1/10.

C leaves 4 days before completion of the work, which means only A and B work during the last 4 days.

Work done by A and B TOGETHER in the last 4 days = 4 (1/24 + 1/30) = 3/10.

Remaining Work = 7/10, which was done by A,B and C in the initial number of days.

Number of days REQUIRED for this initial work = 7 days.

THUS, the total numbers of days required = 4 + 7 = 11 days.

Answer» Step-by-step explanation: Given: For 1ST 100 FEET: 1st TERM (a) = 2.50 Common difference (d) = 2.50 n = 100 Now: an = a + (n-1) d an = 2.50 + (100-1) 2.5 an = 2.50 + 247.50 an = 250 Now: SUM of 100 feet: Sn = (2.50 + 250) Sn = 50 (252.5) Sn = 375 For the other 120 feet: Take 1st term (a) = 2.75 Common difference (d) = 0.25 n = 120 Now: an = a + (n-1) d an = 2.75 + (120-1) 0.25 an = 2.75 + 29.75 an = 32.5 Now: Sum of 120 feet: Sn = (2.75 + 32.5) Sn = 60 (35.25) Sn = 2115 Now: Total cost of 220 feet deep well: Final answer: 2490

14.

the cost of drilling a tubewell is rupees 2.50 per food for the first Hundred feet and an additional rupees 0.25 for every subsequent food find the cost of the last put and the total cost of 220 feet deep tubewell

Answer»

Step-by-step explanation:

Given:

For 1ST 100 FEET:

1st TERM (a) = 2.50

Common difference (d) = 2.50

n = 100

Now:

an = a + (n-1) d

an = 2.50 + (100-1) 2.5

an = 2.50 + 247.50

an = 250

Now:

SUM of 100 feet:

Sn = (2.50 + 250)

Sn = 50 (252.5)

Sn = 375

For the other 120 feet:

Take 1st term (a) = 2.75

Common difference (d) = 0.25

n = 120

Now:

an = a + (n-1) d

an = 2.75 + (120-1) 0.25

an = 2.75 + 29.75

an = 32.5

Now:

Sum of 120 feet:

Sn = (2.75 + 32.5)

Sn = 60 (35.25)

Sn = 2115

Now:

Total cost of 220 feet deep well:

Final answer: 2490

Draw the graph of the polynomial f(x) = x^2-2x-8

Answer»

QUESTION:-

DRAW the graph of the polynomial f(x) = x^2-2x-8

${\red{\underline{\underline{\bold{Answer:-}}}}}$

Given,

f(x)=x² −2x−8

to find the vertex, we know,

x=−b/ 2A = - (-2)/2×1 =1

to find y COORDINATE, substitute the value of x in equation.

(1)² −2(1)−8=1−2−8=9

The vertex is (1,9)

Now, x intercepts,

x² −2x−8=0

(x−4)(x+2)=0

x=−2,4

The x intercepts are (−2,0),(4,0)

To find the y intercept, substitute x=0 in given equation,

0 ²-2(0)−8=−8

The y intercept is (0,−8)

Thus it is an upward facing PARABOLA, touching x and y axis at (2,−8),(−1,−5),(3,−5)

25.	Q. 1) The perimeter of a semicircle is 72 cm. Find the area of a square drawn on itsdiameter.
Answer» ANSWER: AREA of square = 2098.55 cm sq (Approx) Step By Step Explanation: Given: Perimeter of semicircle = 72 cm To Find: Area of square drawn on its diameter. Now, we know that => Perimeter of semicircle = πr => 72 = 22/7 × r => 72 × 7 = 22r => 22r = 504 => r = 504/22 => r = 22.90 cm. Now, Diameter = 2R => Diameter = 2 × 22.90 => Diameter = 45.81 cm Now, we know that square is drawn on diameter. So its diameter be the SIDE of square. => Area of square = side × side => Area of square = 45.81 × 45.81 => Area of square = 2098.55 cm sq. Hence, Area of square = 2098.55 cm sq. (Approx)

25.

Q. 1) The perimeter of a semicircle is 72 cm. Find the area of a square drawn on itsdiameter.

Answer»

ANSWER:

AREA of square = 2098.55 cm sq (Approx)

Step By Step Explanation:

Given:

Perimeter of semicircle = 72 cm

To Find:

Area of square drawn on its diameter.

Now, we know that

=> Perimeter of semicircle = πr

=> 72 = 22/7 × r

=> 72 × 7 = 22r

=> 22r = 504

=> r = 504/22

=> r = 22.90 cm.

Now, Diameter = 2R

=> Diameter = 2 × 22.90

=> Diameter = 45.81 cm

Now, we know that square is drawn on diameter. So its diameter be the SIDE of square.

=> Area of square = side × side

=> Area of square = 45.81 × 45.81

=> Area of square = 2098.55 cm sq.

Hence, Area of square = 2098.55 cm sq. (Approx)

Aditya has built a cubical water tank with lid for his house with each outer edge equal to 1.5m. He gets the outer surface of the tank including the base, covered with square tiles of side 25cm. Find how much he would spend on tiles if the cost of tile is Rs 480 per dozen?

Given:

The edge of the tank = 1.5m = 150cm
COST of 12 tiles = 480

Then:

Surface area of the tank = 5 x 150²

Area of each title = 25²

Therefore:

Number of title required = 5 × 150²/25² = 180

Cost of 1 TILE = 480/12 = 40

The length of a telephone conversation in a booth has been an exponential distribution andfoundon an average to be 5 minutes. Find the probability that a random call made from this boothends less than 4 minutes

Answer»

Given : The length of a telephone conversation in a BOOTH has been an exponential DISTRIBUTION and found on an average to be 5 minutes.

Step-by-step explanation:

Mean = 5 mins

=> λ = 1/5

The cumulative distribution function is given by

= 1 - $e^{- \lambda x }$

λ = 1/5 x = 4 minutes

= 1 - $e^{- \frac{4}{5} }$

= 1 - 0.449

= 0.551

0.551 is the Probability that a random call made from this booth

ends less than 4 minutes

Answer» Given that, Misprints = 300 Pages of book = 500 We need to CALCULATE the value of λ Using formula of λ $\lambda=\dfrac{number\ of\ misprints}{number\ of\ pages}$ Put the value into the formula $\lambda=\dfrac{300}{500}$ $\lambda=0.6$ We need to calculate the probability Using formula of probability $P(x)=\dfrac{e^{-\lambda}\times(\lambda)^{x}}{x!}$ For x=4, Put the value of x $P(4)=\dfrac{e^{-0.6}\times(0.6)^{4}}{4!}$ $P(4)=0.0029$ Hence, The probability is 0.0029.

45.

Suppose 300 misprints are randomly distributed throughout a book of 500 pages, find the probability that a given page contains exactly 4 misprints.

Answer»

Given that,

Misprints = 300

Pages of book = 500

We need to CALCULATE the value of λ

Using formula of λ

$\lambda=\dfrac{number\ of\ misprints}{number\ of\ pages}$

Put the value into the formula

$\lambda=\dfrac{300}{500}$

$\lambda=0.6$

We need to calculate the probability

Using formula of probability

$P(x)=\dfrac{e^{-\lambda}\times(\lambda)^{x}}{x!}$

For x=4,

Put the value of x

$P(4)=\dfrac{e^{-0.6}\times(0.6)^{4}}{4!}$

$P(4)=0.0029$

Hence, The probability is 0.0029.

The difference between two whole numbers is 68. The ratio of the two numbers is 17:13. Find the numbers .

Answer»

QUESTION :- THE DIFFERENCE BETWEEN TWO WHOLE *NUMBERS*** IS 68. THE RATIO OF THE TWO NUMBERS 17 : 13. FIND THE NUMBERS

___________________________________

GIVEN :- •) THE DIFFERENCE IS 68..... •) THE RATIO OF THE TWO NUMBERS IS 17:13

___________________________________

SOLUTION :-

Let the first number be - x

Let the SECOND number be - y

ACCORDING TO THE QUESTION ,

x - y = 68

=> x = 68 + y ____(i)

x : y = 17 : 13

=> x = 17y / 13 ____ (ii)

Therefore PUTTING the value of x from equation (i) to equation (ii) we get ,

68 + y = 17y / 13

=> 13 ( 68 + y) = 17y

=> 884 + 13y = 17y

=> 17y - 13y = 884

=> 4y = 884

=> y = 221

Therefore putting the value of y in eqn (i) we get ,

x = 68 + 221

=> x = 289 ...

Answer :- x = 289 and y = 221
