You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

Answer:

47.5%  is 19 of the 40 .

Step-by-step explanation:

As given

19 is a part value of 40.

Let us assume that the x % is 19 of the number 40.

Now written x % in the decimal form.

= \frac{x}{100}

Than the equation becomes

\frac{x\times 40}{100} = 19

Solving the above

\frac{19\times 100}{40} = x

\frac{1900}{40} = x

x = 47.5%

Therefore  47.5%  is 19 of the 40 .

Q(x)=x^3+ax^2+2b is divided by (x-3) and has a remainder of 4. Find the values of "a" and "b"​
Sati [7]

Answer:

Let p(x) = x3 + ax2 + bx +6

(x-2) is a factor of the polynomial x3 + ax2 + b x +6

p(2) = 0                                                                                      

p(2) = 23 + a.22 + b.2 +6 =8+4a+2b+6 =14+ 4a+ 2b = 0

7 +2 a +b = 0

b = - 7 -2a -(i)                                                                              

x3 + ax2 + bx +6 when divided by (x-3) leaves remainder 3.

p(3) = 3                                                                                      

p(3) = 33 + a.32 + b.3 +6= 27+9a +3b +6 =33+9a+3b = 3

11+3a +b =1 => 3a+b =-10 => b= -10-3a -(ii)                                    

Equating the value of b from (ii) and (i) , we have

(- 7 -2a) = (-10 - 3a)

a = -3                                                                                          

Substituting a = -3 in (i), we get

b = - 7 -2(-3) = -7 + 6 = -1

Thus the values of a and b are -3 and -1 respectively.
