a,b,c together can do a piece of work in 10 days . a takes twice as long as b and c together . b takes as long as a and c together . how much time can c alone take to complete the work​

Answer»

Answer:

according to 1ST condition

a+b+c=10

according to 2nd condition

Step-by-step EXPLANATION:

  • b+c=a

now from point 1 and 2, we get

a+b+c=10

since,b+c =a

therefore we PUT VALUE of b+c as a

thus

a+a=10

2a=10

a=10÷2

thus a=5

now we substitute the value of a=5

a+b+c=10

5+b+c=10

b+c=10-5

b+c=5

according to 3rd condition b take same time as c

therefore dividing the value of b+c by 2

thus 5÷2 = 2.5

therefore c take 2.5 days ALONE

Answer:

1

Step-by-step EXPLANATION:

hello

tan(1665)

tan(9π+45)

tan(8π+π+45)

tan[ 8π+(π+45) ]

for any even multiple of π

tan remain unchanged

so it is tan(π+45)

and in THIRD quadrant tan is positive

so is EQUAL to tan45 which is equal to 1

1/(1 + loga bc) + (1 + logb ca) + (1 + logc ab)(1) 0(2) 1(3) abc(4) 1/abc​

Answer»

ANSWER:

Option 2 is CORRECT.

Step-by-step explanation:

To find VALUE of expression:  \frac{1}{1+log_a\:bc}+\frac{1}{1+log_b\:ca}+\frac{1}{1+log_c\:ab}

We use the following result,

log_c\:x=\frac{log\:x}{log\:c}\:and\:log\,xy=\log\,x+log\,y

Consider,

\frac{1}{1+log_a\:bc}+\frac{1}{1+log_b\:ca}+\frac{1}{1+log_c\:ab}

\implies\frac{1}{1+\frac{log\,bc}{log\,a}}+\frac{1}{1+\frac{log\,ca}{log\,b}}+\frac{1}{1+\frac{log\,ab}{log\,c}}

\implies\frac{log\,a}{log\,a+log\,bc}+\frac{log\,b}{log\,b+log\,ca}+\frac{log\,c}{log\,c+log\,ab}

\implies\frac{log\,a}{log\,a+log\,b+log\,c}+\frac{log\,b}{log\,b+log\,c+log\,a}+\frac{log\,c}{log\,c+log\,a+log\,b}

\implies\frac{log\,a+log\,b+log\,c}{log\,b+log\,c+log\,a}

\implies1

Therefore, Option 2 is correct.

Prove by pmi 1³+2³+3³+...n³=n³(n+1)³/4​

Answer»

Answer:

for n = 1

LHS = 1³ = 1

RHS = [ 1² (1 + 1)² ] / 4 = 4/4 = 1

which is TRUE

SUPPOSE that n = k is true

then

1³ + 2³ + 3³ + ... + k³ = [ k² (k + 1)² ] /4

now suppose that n = k + 1 is true

LHS

= 1³ + 2³ + 3³ + ... + k³ + (k + 1)³

=[ k² (k + 1)² ] /4 + (k + 1)³

= [ k² (k + 1)² + 4(k + 1)³ ] /4

= [ k² (k + 1)² + 4(k + 1)³ ] /4

= [ k⁴ + 2k³ + k² + 4k³ + 12k² + 12k + 4 ] /4

= [ k⁴ + 6k³ + 13k² + 12k + 4 ] /4

RHS

= [ (k + 1)² (k + 2)² ] /4

= [ (k² + 2k + 1)(k² + 4k + 4) ] /4

= [ k⁴ + 6k³ + 13k² + 12k + 4 ] /4

LHS = RHS

P(k) = P(k + 1)

so by mathematical INDUCTION, the statement is true

If a and b both rational numbers ,find the values of the following equalities a) 3+/7 by 3-/7=a+b/7 and b) /2+/3 by 3/2-2/3=a-b/6

Answer»

ANSWER:

a) RATIONALIZING \frac{<klux>3</klux> + √<klux>7</klux>}{3 - √7} = a + √b

  (3+√7) * (3+√7) / (3 + √7) * (3 - √7) =  a + √b

There are n terms in ana.P. Where n is even. The sum of odd terms and even terms are 63 and 72 respectively. The last term is greater than first term by 16.5 , calculate n.

Answer»

Answer:

12

Step-by-step explanation:

There are n terms in an  a.P. Where n is even. The sum of odd terms and even terms are 63 and 72 respectively. The last term is greater than FIRST term by 16.5 , calculate n

Let SAY  n = 2k

AP is

a  , a + d , a + 2d , +.............................................a + (2k-2)d  ,  a + (2k-1)d

The last term is greater than first term by 16.5

=> a + (2k-1)d - a = 16.5

=> (2k-1)d = 16.5  

=> 2kd  - d = 16.5 eq 1

Odd terms

a  , a + 2d  , ..............................................a + 2(k-1)d

in this Ap First Term = a  CD = 2d  & number of Terms = k

Sum = (k/2)(a + a + 2(k-1)d)  = 63

=> k (2a + 2(k-1)d) = 126  - eq 2

Even terms

a+d  , a + 3D  , .............................................,.a + (2k-1)d

in this Ap First Term = a+d  Cd = 2d  & number of Terms = k

Sum = (k/2)(a + d + a + (2k-1)d)  = 72

  => (k)( 2a + 2kd) = 144    eq 3

eq 3 - eq 2

=> k ( 2d) = 18

=> kd = 9

putting in eq 1

2*9 - d = 16.5

=> d = 1.5

kd = 9

=> k(1.5) = 9

=> k = 6

n = 2k = 2 * 6 = 12

Hence number of terms = 12

AP is

3 , 4.5 , 6 , 7.5 , 9 , 10.5 , 12 , 13.5 , 15 , 16.5 , 18 , 19.5

What is the smallest square number, which is divisible by 2,4,5,6 and 9 ?

Answer»

Answer:

Smallest square NUMBER, which is divisible by 2,4,5,6 and 9 is 900.

Step-by-step explanation:

  1. LCM = 2 = 2 = 2
  2. 4 = 2 x 2 = 22
  3. 5 = 5 = 5
  4. 6 = 2 x 3 = 2 x 3
  5. 9 = 3 x 3 = 32

The Product of all factors with highest powers LCM = 2^2 x 3^2 x 5 = 2 x 2 x 3 x 3 x 5

LCM = 180

square No. = 2 x 2 x 3 x 3 x 5 x 5 = 900

A mobile phone is sold for $3,120 at a loss of 4%. What will be the gain or loss percentage if it is sold for$ 3,120​

Answer»

Solution: Here, S.P. = 3,120

Loss= 4%

C.P. = 100*S.P.

100-loss%

= $100*3,120

100-4

= $100*3120

96

= $ 3,250

Now, new S.P. = $3,640

Gain = S.P. - C.P.

= $ 3,640- $ 3,250= $ 390

Hence, Gain%= Gain * 100

C.P.

= 390 * 100

3,350

= 12%
