The breadth of a rectangle is 1.28 m and the length is 72 cm more than its breadth. i) Find out the length of the rectangle in meters. ii.) The perimeter of the above rectangle will be. iii.) If Ahmed doubles the length and keeps the breadth same of the above rectangle, how much will be the area of the new rectangle?

Answer»

Answer:

(i) LENGTH = 2 m

(II) Perimeter = 656 cm = 6.56 m

(iii) Area = 25600 cm² = 2.56 m²

Step-by-step explanation:

(i) Breadth of the rectangle = 1.28 m = 128 cm

Let the length of the rectangle be x

Length = 128 + 72 = 200 cm = 2 m

(ii) Perimeter = 2(l + b)

= 2(128 + 200)

= 2 × 328

= 656 cm

= 6.56 m

(iii) Length = 2 × 200 = 400 cm = 4 m

Breadth = 128 cm = 1.28 m

Area of the rectangle = l × b square UNITS

= 128 × 200

= 25600 cm²

= 2.56 m²

If (x+3)&(x-4) are the factors of x³+ax²+bx+24, find the values of a&b. With these values of a& b, factorise the given expression ​

Answer»

\large{\underline{\bf{\red{Given:-}}}}

  • ✦ (x + 3) and (x -4 ) are factors of polynomial x³+ax²+bx+24,

\large{\underline{\bf{\red{To\:Find:-}}}}

  • ✦ value of a and b

\huge{\underline{\bf{\pink{Solution:-}}}}

p(x) = x³ + ax² + bx + 24

we know that

(x + 3) and (x -4 ) are factors of the given polynomial.

then,

  • x = -3 or x = 4

putting value of x = -3 in the polynomial.

➝ x³+ax²+bx+24

➝ (-3)³ + a × (-3)² + b ×(-3) +24

➝ -27 + 9a - 3b +24

➝ 9a - 3b -3 =0

Divide both side by 3

we get,

➝ 3a - b -1 = 0 ..........(i)

Now,

putting value of x = 4 in the polynomial.

➝ x³+ax²+bx+24,

➝ (4)³ + a × (4)² + b × (4) +24

➝ 64 +16a + 4B + 24

➝ 16a + 4b + 88 = 0

Divide both side by 4.

we get,

➝ 4A + b + 22 = 0 ..........(ii)

Now , solving equation (i) and (ii)

3a - b = 1

4a + b = -22

7a ⠀⠀= ⠀-21

a⠀⠀⠀ = -21/7

a⠀⠀⠀= -3

putting value of a in equation (i)

we get,

3a - b -1 =0

➝ 3a - b = 1

➝ 3× (-3) - b = 1

➝ -9 - b = 1

➝ - b = 10

➝ b = -10

So, value of a = -3 and b = -10

Prove that:-√1+cosA÷ 1+cosA + √1- cosA÷ 1+cosA= 2 cosecA ( it is whole root over in LHS but separately).​

Answer»

Answer :  LHS=RHS

1-cosA=2sin²(½A)

1+cosA≈2cos²(½A)

Hence,

LHS=√｛sin²(½A)/cos²(½A)｝=TAN(½A)

RHS=(1/s)-(c/s)≈(1-c)/s=2sin²(½A)/2sin(½A)cos(½A)=SIN(½A)cos(½A)

Using properties of proportion,solve the equation:-x^3+3x/3x^2+1=341/91

Answer»

Step-by-step explanation:

Sol: Given (x3+3x) / (3x2+1) = 341 / 91. Apply the componendo and dividendo ⇒ (x3+3x) + (3x2+1) / (x3+3x) - (3x2+1) = (341 + 91) / (341 - 91). ⇒ (x3 + 3x2 + 3x + 1) / (x3- 3x2 +3x -1) = (341 + 91) / (341 - 91). ⇒ (x + 1)3 / (x - 1)3 = 432 / 250. ⇒ (x + 1)3 / (x - 1)3 = 216 / 125 . ⇒ (x + 1)3 / (x - 1)3 = 63 / 53 . ⇒ (x + 1) / (x - 1) = 6 / 5 .(again apply the componendo and dividendo) ⇒ (x + 1) + (x - 1) /(x + 1) - (x - 1) = (6 + 5) / (6 - 5) ⇒ 2x / 2 = 11 / 1 ∴ x = 11.

Answer»

Given :   the probability that bob will have breakfast is more than 0.6. the

probability that bob will have breakfast and will have a sandwich for lunch is less than 0.5. the probability that bob will have breakfast or

will have a sandwich for lunch equals 0.7.  

To find :  probability that, on any given DAY, bob will have a sandwich for lunch

Step-by-step EXPLANATION:

probability that bob will have breakfast  B >  0.6

probability that bob will have breakfast and will have a sandwich for lunch ( B & L )  <  0.5.

=> P(B)P(L) <  0.5

breakfast or Lunch   =  P(B)  + P(L)  -  P(B)P(L)  = 0.7

P(L)  -  P(B)P(L)  = 0.7 - P(B)

P(B) >  0.6

P(L)  -  P(B)P(L)   < 0.1

=> P(L) < 0.1 + P(B)P(L)

P(B)P(L)  < 0.5

=> P(L)  <  0.6

Probability bob will have a sandwich for lunch.    <  0.6

If fourth degree polynomial is divided by a quadratic polynomial then the degree of the quotient is

Answer»

Answer:

The remainder will be less than or equal to zero.

For ex: LET G (X) = divisor

and f (x) = dividend

g (x)= quadratic poly nomial

g (x) = ax^2 + bx +c

Degree of f (x) = 4

Degree of g (x) = 2

So, degree of quotient = 4-2 = 2.

Here, you can see that the degree of R (x) =2 has degree 1

You can try with another examples also.

In a class test (+4) marks are given for every correct answer and (-2) marks are given for every incorrect answer and no marks for not attempting any questions. Amana answered all the questions and scored 30 though she got 10 correct answers. i) Number of questions she has attempted incorrectly is. ii) Number of questions given in the test

Answer»

Given :-

  • Total marks given for each correct answer = 4
  • Total marks deducted for each incorrect answer = 2
  • Total marks scored by Amana = 30
  • Number of correct answers given by her = 10

To Find :-

  1. Number of QUESTIONS she has attempted incorrectly.
  2. Number of questions given in the test.

Solution :-

SUPPOSE x be the number of incorrect answers given by Amana. Then, total marks reduced will be : -2(x)

ALSO, she had given 10 correct answers. Then, total marks she got (before been reduced) = 4 × 10 = 40

ACCORDING to the question,

⇒ 40 - 2X = 30

⇒ 2x = 40 - 30

⇒ 2x = 10

⇒ x = 10/2

⇒ x = 5

Therefore, Amana attempted 5 questions incorrectly.

Also,

Total number of questions in the test,

⇒ 10 + 5 ( ∵ she attempted all questions).

⇒ 15

Hence,

  1. Number of questions she had attempted incorrectly = 5
  2. Number of questions given in the test = 15

Rihana's age is 3 years more than double the age of Koina. Three years ago, Rihana was 3 times old as Koina then. Find their percentage ages.

Answer»

Step-by-step explanation:

let the AGE of koina be x

rihanas age is 3 years more then DOUBLE the age of koina= 2x + 3

second condition,

3 years ago joins age was = x-3

and rihanas was 3 times old as kohina= 3( x-3)

I.e. => 3 (x-3) = x-3

3x - 9 = x-3

2x= 6

x= 3

so joins age is 3

subs. x = 3 in first equation

2x + 3

2 X 3 + 3

6+ 3

so rihanas age is 9

if 21 is added to both; 5x+21 = 2×(x+21)

5x + 21 = 2x + 42
