2.	If 47. 2506 = 4A + 7/B + 2C + 5/D + 6E, then the value of 5A + 3B + 6C + D + 3*E is :A) 55.6003 B) 53.603 C) 153.6003 D) 213.003
Answer» Answer: Option C) is correct Step-by-step explanation: 4A + 7/B + 2C + 5/D + 6E =47.2506 => 4 A + 7/B + 2 C + 5/D + 6E = 40 + 7 + 0.2 + 0.05 + 0.0006 COMPARING the terms on both sides, we get : 4A =40, 7/B = 7, 2C = 0.2, 5/D = 0.05, 6E = 0.0006 A = 10, B = 1, C = 0.1, D = 100, E = 0.0001. 5A + 3B + 6C + D + 3E =(510) + (31) + (60.1) +100 +(3*0.0001) =50 + 3 + 0.6 + 100 + 0.003 = 153.6003.

If 47. 2506 = 4A + 7/B + 2C + 5/D + 6E, then the value of 5A + 3B + 6C + D + 3*E is :A) 55.6003 B) 53.603 C) 153.6003 D) 213.003

Answer»

Answer:

Option C) is correct

Step-by-step explanation:

4*A + 7/B + 2*C + 5/D + 6*E =47.2506

=> 4 * A + 7/B + 2 *C + 5/D + 6*E = 40 + 7 + 0.2 + 0.05 + 0.0006

COMPARING the terms on both sides, we get :

4*A =40, 7/B = 7, 2*C = 0.2, 5/D = 0.05, 6*E = 0.0006

A = 10,

B = 1,

C = 0.1,

D = 100,

E = 0.0001.

5*A + 3*B + 6*C + D + 3*E =(5*10) + (3*1) + (6*0.1) +100 +(3*0.0001)

=50 + 3 + 0.6 + 100 + 0.003 = 153.6003.

5.	If (x+2) a factor of polynomial x cube - 6x square + 11x-6
Answer» Step-by-step explanation: Not in time for the exam, but anyhoo... If you can't find common factors to extract from an equation like this, the NEXT step (at least when it's neat enough to have integer - or at least rational - COEFFICIENTS) is to attempt to guess rational solutions. Given the condition in the parenthesis above, that is actually fairly easy, as there exists a condition on what rational solutions are possible: Assume, for the generality of it, that we have the equation anxn+…+a1x+a0=0 where all coefficients are integers. Construct the two SETS A0 consisting of all divisors of a0 (in this case A0={1,2,3,6} ), and A1 consisting of all divisors of an (in this case A1={1} . If the equation has a rational SOLUTION ±pq , then p∈A0,q∈A1 . Thus, in this case, the only possible rational solutions are 1/1, 2/1, 3/1, 6/1, -1/1, -2/1, -3/1, -6/1. Additionally, we can see that no solution may be negative (that would have given a sum of four negative terms, adding to zero), so we have only four numbers to try: 1,2,3, and 6. Of course, besides trial and error, we have no way to guarantee that this will provide us with a solution, but we can then say that any solution - beyond what this trial run gave - will be irrational, and may require the general formula for the solution of a cubic equation (in this case).

Step-by-step explanation:

Not in time for the exam, but anyhoo...

If you can't find common factors to extract from an equation like this, the NEXT step (at least when it's neat enough to have integer - or at least rational - COEFFICIENTS) is to attempt to guess rational solutions. Given the condition in the parenthesis above, that is actually fairly easy, as there exists a condition on what rational solutions are possible:

A sum of rs 1600 gives a simple interest of rs 252 in 2yrs and 3month the rate of interest per annum

Answer»

Answer:

7%

Step-by-step EXPLANATION:

p=1600

SI=252

N=2 YEARS + 3/12= 2+ 1/4=9/4 years

SI =pnr/100

R = 100* SI /(p*n)

Step-by-step explanation:

TOTAL MONEY SHE HAS---> 9 rupees

let no. of 50 paisa and 25 paisa coins be x and y respectively.

According to question:

2x=y ----equation 1

x + y = 9

putting the value of y from first equation:

3x=9

x=3

putting x in equation 1

2×3=y

39.	{2^(3x-1)+10} ÷21 = 18
Answer» Answer: ☺☺☺ Step-by-step explanation: Multiply both SIDES of the equation by 21. 23x - 1 + 10 = 278 Subtract 10 on both sides of the equation. 23x - 1 = 268 LOG both sides of the equation and BRING all exponents as the coefficient of logs. (3x - 1)Log(2) = Log(268) 3x - 1 = Log(268) / Log(2) 3x = [Log(268) / Log(2)] + 1 x = (1/3) * [(Log(268) / Log(2)) + 1]

{2^(3x-1)+10} ÷21 = 18

Answer»

Answer:

☺☺☺

Step-by-step explanation:

Multiply both SIDES of the equation by 21.

23x - 1 + 10 = 278

Subtract 10 on both sides of the equation.

23x - 1 = 268

LOG both sides of the equation and BRING all exponents as the coefficient of logs.

(3x - 1)Log(2) = Log(268)

3x - 1 = Log(268) / Log(2)

3x = [Log(268) / Log(2)] + 1

x = (1/3) * [(Log(268) / Log(2)) + 1]

Answer»

Answer:

Fraction to DECIMAL CONVERSION Tables

fraction = decimal

1/16 = 0.0625 3/16 = 0.1875 5/16 = 0.3125

11/16 = 0.6875 13/16 = 0.8125

1/32 = 0.03125 3/32 = 0.09375 5/32 = 0.15625

The diameter of planet mercury is 4878000 m and that of the planet Uranus is 51200000 m. Find the radii of both the planets in kilometers. Which planet is bigger and by how much?

Answer»

ANSWER:

diameter of Mercury= 4878000m= 4878 km

so radius = diameter/2= 2439 km

diameter of URANUS = 51200000m = 51200km

so radius = diameter/2 = 25600 km

so Uranus is BIGGER than Mercury as 51200 km > 2439 km
