on a morning walk three person step of together and their steps measure 40cm ,42cm and 45cm. what is the minimum distance each should walk so that each can cover the same distance and complete the steps?

Answer»

Answer:

2520cm

Step-by-step explanation:

given by , 3 PERSON step of together and their steps measure 40cm , 42CM and 45cm.

minimum distance = l.C.M OF their steps meassure.

here,

40 = 2×2×2×5

42=2×3×7

45= 3×3×5

L.C.M = 2×2×2×3×3×5×7= 2520cm

the minimum distance each can cover the same distance and COMPLETE the steps = 2520cm

Define linear independence​

Answer»

Answer:

In the theory of VECTOR spaces, a SET of vectors is said to be linearly dependent if at LEAST one of the vectors in the set can be defined as a linear combination of the others; if no vector in the set can be written in this WAY, then the vectors are said to be linearly independent.

By what smallest number 26244 should be divided to get perfect cube.also find its cube root​

Answer»

root of the quotient.

                   

       26244

        / \

       2  13122

          / \

         2  6561

            / \

           3  2187

              / \

             3  729

                / \

               3  243

                  / \

                 3  81

                    / \

                   3  27

                      / \

                     3   9

                        / \

                       3   3

                     

So   26244 = 2238  

To become a cube, all the prime factors of it must  

be to a power which is a multiple of 3.

Notice that the prime number base 2 in the factorization

is RAISED to the 2nd power (exponent), but exponent 2 is  

NOT a multiple of 3, so we'll have to multiply by the 1st  

power of 2 so that when we add exponents of 2 we will get 23.

Notice also that the prime number base 3 in the factorization

is raised to the 8TH power (exponent), but exponent 8 is  

NOT a multiple of 3, so we'll have to multiply by the 1st  

power of 3 so that when we add exponents of 3 we will get 39.

So we have to multiply by 2131

or 2∙3 or 6 to cause 26244 to become a perfect cube.

So we have to multiply 2238 by 2131

so that it will become 2339 and both prime bases 2 and 3

will be raised to powers (exponents) which are both MULTIPLES of 3.

So then the cube root of 2339 will be gotten

by dividing each exponent by 3, which will give 2133 which

is 2∙27 or 54.

That's the same as saying

The 26244 must be multiplied by 6 gives 157464 which is a  

perfect cube.  It is a perfect cube because 543 = 157464.

And the cube root is 54 because 54∙54∙54 = 157464.

Ahow that any positive integer is of the form 4n, 4n+1 or 4n+3, where n is a integer?​

Answer»

ANSWER:

As PER Euclid's division lemma

if a and b are two positive integers then

a = bq+r

where 0 is LESS than or equal to r and r is less than b

let positive INTEGER be a.

and b= 4

hence a=4q+r

where r is an integer greater than or equal to 0 and less than 4.

hence r can be either 0,1,2 or 3

if r = 1

our equation becomes

a=4q+r

a=4q+1

this will always be an odd integer.

if r=3

a=4q+r

a=4q+3

this will always be an odd integer

therefore, any odd integer is of the form 4q+1 or 4q+3

hence proved

hope it helps

Step-by-step EXPLANATION:

let RAM's share be X

then,. Mohan's share = x-6

Sohan's share = x-9

A/q

x+(x-6)+(x-9) = 33

x+x-6+x-9 = 33

3X-15 =33

3x = 33+15

3x = 48

x = 48/3 = 16

The largest number which divides 70 and 125 and leaves remainder 5 and 8 is​

Answer»

Answer:

Step-by-step explanation:

13

Since, 5 and 8 are the remainders of 70 and 125, respectively. THUS, after subtracting these remainders from the numbers, we have the numbers 65 = (70 – 5), 117 = (125−8), which is DIVISIBLE by the REQUIRED number. Hence, 13 is the largest number which divides 70 and 125, leaving remainders 5 and 8.

Find the reminder when x³+3x²++1 divided by x-1/2​

Answer»

GIVEN

p(X) = x^3 + 3x^2 +1

g(x) = x - 1/2

TO FIND :- REMAINDER when p(x) is divided by g(x)

SOULTION

As the degree of g(x) is 1 instead of long division method we can apply remainder theorem.

Remainder Theorem states that when we insert the zero of g(x) in place of x in p(x) then the result is EQUAL to its remainder.

Now zero of g(x)

x - 1/2 = 0

=> x = 1/2

Hence the zero of g(x) = 1/2

We can put this VALUE in p(x)

p(x) =  {x}^{3}  + 3 {x}^{2}  +1 \\  \\  \\    p( \frac{1}{2} ) =  { (\frac{1}{2}) }^{3}  + 3 {( \frac{1}{2} })^{2}  + 1 \\  \\  \\  =  \frac{1}{8}  +  \frac{3}{4}  + 1 \\  \\  \\  =  \frac{7}{8}  + 1 \\  \\  \ \  =   =  \frac{15}{8}  = 1 \frac{7}{8} (ans)

Hence the remainder when p(x) divided by g(x) is 15/8 (ANS).

Pls solve question number 5 (i)

Answer»

Step-by-step explanation:

first of all we have to find the lcm of 6 and 8 which is 24 . so as we all know that 6x4 EQUALS 24 then 1x4 equals 4 .the the fraction is now 4 by 24 . now 8x3 equals 24 and 3x3 equals 9 . so the fraction is now 9 by 24 . if we plus them it give answer 13 by 24 from which we have to subtract 1 upon 4 . we can change 1 upon 4 by multiplying it by 6 . the answer will be 6 upon 24 . so the answer is 7 upon 24

2sin x+15cos^2 x=7then find tan x​

Answer»

Answer

sin²x+cos²x =1 (identity)

cos²x = 1-sin²x

2sinx +15cos²x =7

put 1-sin²x instead of cos²x

2sinx +15(1-sin²x) =7

-15sin²x +2sinx +8=0 => (form of a quadratic equation)

SINA =t

-15t² +2T +8=0

t= 4/5 and t = -2/3 => (after using quadratic formula)

t = 4/5 is the real solution (the other one makes a negative ANGLE)

sinx= 4/5

sin²x = 16/25 => (after squaring both sides)

remember identity sin²a+cos²a=1 => sin²a = 1-cos²a

1-cos²x =16/25 => cos²x=9/25 => cosx =3/5 ( the other solution -3/5 makes negative angle)

tanx = sinx / cosx = > (4/5) /(3/5) = 4/3

A teacher bought 40 calculators at $8.20 each and a number of other calculator costing $2.95 each. In all he spent $387. How many of the cheap calculators did he buy?

Answer»

Let N be the NUMBER of cheaper CALCULATORS. Then

n*2.95 + 40*8.20 = 387

n*2.95 = 387 - 40*8.20

n = (387 - 40*8.20)/2.95

n = 20

euclid,s division lemma states that for two positive integers a and b there exist unique integers q and r such that a=bq+r what condition r must satisfy.​

Answer»

Answer:

Step-by-step explanation:

a = 3q+r (Given)

b = 3 (Given)

According to the concept of EUCLID’s division Lemma, every integer has a certain divisibility rule. It states that any positive integer say ‘a’ can be divided by any other positive integer say ‘ b’ in such a way that it will LEAVE the remainder ‘r’. It further states that for any two positive integers ‘a’ and ‘b’ there exists two unique WHOLE numbers say ‘Q’ and ‘r’ such that , a = bq + r, where 0 ≤ r < b.

Where, a is the dividend, b is the divisor, q is the quotient and r is the remainder.

As per the question, since the integers are a and 3, thus  

Let the VALUES that 'r’ can take = 0 ≤ r < 3.

Therefore, the possible values 'r’ will be 0,1,2.
