Shripati sold a land for Rs. 2,50,000 to Mr. Sadashiv through a broker. Broker received 2% brokerage from both. Find the total brokerage received by the broker.

Answer» BROKER received BROKERAGE from Shripati = 2% of 250000
= 2 × 250000/100
= 2 × 2500 = 5000 Rs.

again Broker received brokerage from SADASHIV = 2% of 250000
= 2 × 250000/100
= 2 × 2500 = 5000 Rs.

hence, total brokerage received by the broker = 5000 + 5000 = 10,000 Rs.

Centuries scored and number of cricketers in the world are given below.Find the mean, median and mode of the given data.No. of centuries 5 10 15 20 25No. of cricketers 56 23 39 13 8

Answer»

Answer:

Mean = 11

Mode = 5

Median = 10

Step-by-step explanation:

No. of centuries    No. of CRICKETERS         Cumulative

5                           56                                 56

10                          23                                 79

15                          39                                 118

20                         13                                  131

25                          8                                  139

Mean = ( 5 * 56 + 10*23  + 15*39 + 20*12  + 25*8)/139

= (280 + 230 + 585 + 240 + 200)/139

= 1535/139

≈ 11

Mode= 5   ( 56 players MAX)

Median = 10

Answer» P ( x, y)

O ( 0, 0)

OP = SQRT [ (x1 - x2)^2 + (y1 - y2)^2]

OP = sqrt [ (x - 0)^2 + (y - 0)^2]

OP = sqrt [ x^2 + y^2]

What will be the sum of odd number 1 to 49

Answer»

A = 1

d = 2

L = 49

=> a + (N-1)d = 49

=> 1 + (n-1) (2) = 49

=> (n-1) (2) = 48

=> n - 1 = 24

=> n = 25

Required sum = n/2 [ a + L]

= 25 / 2 [ 1 + 49]

= 25 × 50 / 2

= 25 × 25

= 625

The sum of three consecutive multiples of 7 is 777. find these numbers

Answer»
\mathbf{solution} \\  \\  \\

LET numbers are 7x, 7( x + 1 ) and 7( x + 2 )



Given, their sum = 777


7x + 7( x + 1 ) + 7( x + 2 ) = 777


x + x + 1 + x + 2 = 111


3( x + 1 ) = 111


x + 1 = 37


x = 36






Number are

7x = 7(36) = 252
7( x + 1 ) = 7(37) = 259
7( x + 2 ) = 7(38) = 266

Proof of Heron's Formula Step by step No spamming or lazy answers plz

Answer»

yeah SURE for your HELP


_________________________________________________________________________________________________________________________________________________


Glad to answer this !


Derivation of Heron's Formula


Area of triangle ABC

A=1 /2bh → equation (1)

From triangle ADB

x2+h2=c2

x2=c2–h2

x=c2−h2−−−−−−√


From triangle CDB

(b–x)2+h2=a2

(b–x)2=a2–h2

b2–2bx+x2=a2–h2


Substitute the values of x and x2

b2–2bc2−h2−−−−−−√+(c2–h2)=a2–h2

b2+c2–a2=2bc2−h2−−−−−−√



Square both sides

(b2+c2–a2)2=4B2(c2−h2)

(b2+c2–a2)24b2=c2−h2

h2=c2−(b2+c2–a2)24b2

h2=4b2c2−(b2+c2–a2)24b2

h2=(2BC)2−(b2+c2–a2)24b2

h2=[2bc+(b2+c2–a2)][2bc−(b2+c2–a2)]4b2

h2=[2bc+b2+c2–a2][2bc−b2−c2+a2]4b2

h2=[(b2+2bc+c2)–a2][a2−(b2−2bc+c2)]4b2

h2=[(b+c)2–a2]⋅[a2−(b−c)2]4b2

h2=[(b+c)+a][(b+c)−a]⋅[a+(b−c)][a−(b−c)]4b2



h2=(b+c+a)(b+c−a)(a+b−c)(a−b+c)4b2

h2=(a+b+c)(b+c−a)(a+c−b)(a+b−c)4b2

h2=(a+b+c)(a+b+c−2a)(a+b+c−2b)(a+b+c−2c)4b2

h2=P(P−2a)(P−2b)(P−2c)4b2 note: P = perimeter

h=P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

Substitute h to equation (1)

A=12bP(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

A=14P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√

A=116P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P−2a2)(P−2b2)(P−2c2)−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P2−a)(P2−b)(P2−c)−−−−−−−−−−−−−−−−−−−−−−−−−−√



h2=(b+c+a)(b+c−a)(a+b−c)(a−b+c)4b2

h2=(a+b+c)(b+c−a)(a+c−b)(a+b−c)4b2

h2=(a+b+c)(a+b+c−2a)(a+b+c−2b)(a+b+c−2c)4b2

h2=P(P−2a)(P−2b)(P−2c)4b2 note: P = perimeter

h=P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

Substitute h to equation (1)

A=12bP(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

A=14P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√

A=116P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P−2a2)(P−2b2)(P−2c2)−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P2−a)(P2−b)(P2−c)−−−−−−−−−−−−−−−−−−−−−−−−−−√


Hence proved


Recall that P/2 = s. Thus,

A = \sqrt{s(s - a)(s - b)(s - c)}

Ab and ba are 2 two-digit numbers such that ab + ba = cac. what is a+b+c ? (assume c is not 0 )

Answer»

So,


ab + ba = cac


This situation can be written numerically as,


10a + b + 10 b + a = 100c + 10a + c


11a + 11b = 10a + 101c


a + 11b = 101c


Now, a and b are digits,

HENCE they are 1 digit numbers

So,


The value of c MUST be definetly 1 ,

Reason :


Let US take a and b as 2 digit numbers,


10 + 110 = 120


Now,


120 = 101 c


So,

c can be only 1 because c= 2 will make a and b 2 digit numbers


So,


a + 11b = 101


So,

The only combination which satisfies this is

(2, 9)


So,

a= 2 , b= 9 ,c =1

So,

a + b +c = 2 + 9 + 1 = 12


So,

The NUMBER is 12

Number of villages with respect to their population as per India census 2011 are given below. Find the average population in each village.Find the average population in each village.Population (in thousands) 12 5 30 20 15 8Villages 20 15 32 35 36 7

Answer» HI,

To calculate average POPULATION of each village


first LET us count total NUMBER of VILLAGES:

Total number of villages
= 20 + 15 + 32 +35 +  36 + 7 \\  = 35 + 67 + 43 \\  = 145 \\
total population :

= 12000 + 5000 + 30000 + 15000 + 20000 + 8000 \\  = 17000 + 45000 + 28000 \\  = 90000
Average population of each village = 90000/145

= 620.69
so, Average population of each village is 620.69.
