0.123 bar on 3 can you answer the question

Answer»

Let x = 0.12333333.....

100x = 12.333333... ------(1)

1000X = 123.333333... -------(2)

On subtracting equation 1 from 2, we get

990x = 111

=> x = 111/ 990

=> x = 37 / 330

Required FRACTION = 37/330

Contribution of mathematician narendra karmarkar in india

Answer»

Karmarkar's algorithm solves linear PROGRAMMING problems in polynomial time. These problems are represented by "n" variables and "m" constraints. The previous METHOD of solving these problems consisted of problem representation by an "x" sided solid with "y" VERTICES, where the solution was approached by traversing from vertex to vertex. Karmarkar's novel method approaches the solution by cutting through the above solid in its traversal. Consequently, complex optimization problems are solved much faster using the Karmarkar algorithm. A practical example of this efficiency is the solution to a complex problem in communications network optimization where the solution time was reduced from WEEKS to days. His algorithm thus enables faster business and policy decisions. Karmarkar's algorithm has stimulated the development of several interior point methods, some of which are used in current codes for solving linear PROGRAMS.

27.

Vijay invested Rs.50,000 partly at 10% and partly at 15%. His total income after a year was Rs.7000. How much did he invest at the rate of 10%?

Answer»

Let the amount Vijay invested at the rate of 10% = Rs x

then the amount invested at 15% = Rs (50,000 - x)

TIME = 1yr

Income from 10% rate = 10% of x = x/10

Income from 15% rate = 15% of (50,000 - x) = (150,000 - 3x)/20

Acc to ques, [x/10] + [(150,000 - 3x)/20] = 7000

or, 150000 - x = 140000

or, x = 10,000.

Therefore, he has invested Rs 10,000 at 10% and Rs 40,000 at 15%.

Two circles with centre o and radius r and with centre o' and radius r/2 touch each other internally at a point A and AB is a chord of the bigger circle intersecting smaller circle at P . If o , o' and A lie on a straight line , prove that AP = AB .

Answer» CLEARLY o , o' and A lie on a straight line
B , P and A lie on a straight line
in smaller circle,o'A is diameter
angle o'PA=90 ,o'P is perp on AB
for bigger circle,lets drop perp OL on AB
tr AO'P similar tr AOL
therefore,OL is perp on AB & L bisects AB
AP=1/4 AB

Between 150 and 298 how many numers are divisible by 7

Answer»

A = 154

d = 7

L = 294

=> a + (n-1) d = 294

=> 154 + (n-1)(7) = 294

=> (n - 1)(7) = 140

=> n-1 = 20

=> n = 21

Required NUMBER of TERMS = 21

if alpha and beta are two zeros ofpolynomial 2x2 -3x -5 then find the value of alpha + beta ÷ alpha +× beta

Answer»

Heya !!



2X² - 3X - 5




Here,


A = 2 , B = -3 and C = -5



Sum of zeroes = -B/A



ALPHA + BETA = 3/2




And,


PRODUCT of zeroes = C/A



Alpha × Beta = -5/2






Therefore,




Alpha + Beta / Alpha × Beta = 3/2 / -5/2



=> 3/2 × 2/ - 5




=> - 3/5.

Diagramming of sentences.diagramming of sentences.

Answer»

In pedagogy and theoretical syntax, a sentence diagram or parse tree is a PICTORIAL representation of the grammatical STRUCTURE of a sentence. The term "sentence diagram" is used more in pedagogy, where SENTENCES are diagrammed. The term "parse tree" is used in linguistics (especially computational linguistics), where sentences are parsed. The purpose of sentence diagrams and parse TREES is to have a model of the structure of sentences. The model is informative about the RELATIONS between words and the nature of syntactic structure and is thus used as a tool to help predict which sentences are and are not possible.
