Answer» GIVEN, the length and breadth of a rectangle are in the ratio 3:2 RESPECTIVELY. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m.According to the problem, Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m.According to the problem,2
or, 20x+10=21x+7 or, 20x+10=21x+7or, x=3. or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively. or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now AREA of the rectangle be 9×6=54 m or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now area of the rectangle be 9×6=54 m 2 or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now area of the rectangle be 9×6=54 m 2 . |

The ratio of base to height of a parallelogram is 1:2. If the area of parallelogram is 450 sq metre, then find its base and height |
Answer» Answer:Breadth = 15 m Height = 30 m Step-by-step explanation:GIVEN, \frac{Base of the Parallelogram}{Height of the Parallelogram} HeightoftheParallelogram BaseoftheParallelogram
= \frac{1}{2} 2 1
Height = 2 x Base of the Parallelogram for simplicity we will assume Height = h and Base =b then h = 2b----------------------------equation 1 they already given the area of the Parallelogram = 450 m^{2}m 2
Area of Parallelogram = Base x Height 450 = bh 450 = b x (2b) {substituted the value of h from equation 1 ] 450 = 2b^{2}b 2
225 = b^{2}b 2
b = \SQRT{225} 225
= 15 m = Base of the Parallelogram substitute the value of b in Equation 1 to get h (Height) h = 2b = 2 x 15 = 30 m Hence, Base of the parallelogram = 15 m Height of the Parallelogram = 30 m |

Multiplicative inverse of (2*6)power 2 |
|
Answer» Answer: The procedure to use the multiplicative inverse calculator is as follows: STEP 1: Enter the values in the numerator and denominator INPUT field Step 2: Now click the button “Solve” to get the output Step 3: The multiplicative inverse value will be displayed in the “Answer” field What is Multiplicative Inverse? When a number is multiplied by its multiplicative inverse, it should be EQUAL to 1. In other words, the multiplicative inverse of a number is another number, when its product is equal to 1. The multiplicative inverse is also KNOWN as “Reciprocal”. Standard Formula The standard form to represent the multiplicative inverse is as follows If “n” is a number, then the multiplicative inverse or reciprocal of a number is “1/n”. If a number is given in the fractional form “a/b”, then the multiplicative inverse is “b/a”. |

Find the13th term of the sequence 12, 21, 30,.. |
|
Answer» Answer: What is the next number of the sequence 3, 12, 21, _, _, _? The PATTERN from what is given looks to be that 3, 12, 21, _, _, _ is 3, 3+9, 12+9, _, _, _ ⟹3, 3+9, 3+18, _, _, _ ⟹3+9×0, 3+9×1, 3+9×2, _, _, _. So, continued on INDEFINITELY, the nth––– number of the given sequence is 3+9n. So the 4th number is obtained by letting n=4 in the formula: 3+4×9=3+36=39. Filling in the next two blanks SHOWN in the question, get 3+5×9=3+45=48 and 3+6×9=3+54=57.

2) Areaof a rhombusis 96sq.cm. One of thediagonals 12cm then, then tengthanother diagonal is |
|
Answer» Given : To find :
Knowledge Required : → FORMULA of Area of rhombus :-
where,
Solution : Length of second diagonal :- → Area = 1/2 × d₁ × d₂ → 96 = 1/2 × 12 × d₂ → 96 = 6 × d₂ → 96/6 = d₂ → 16 = d₂ Therefore,
━━━━━━━━━━━━━━━━━━━━ Verification :- Substitute the VALUE of d₂ in 96 = 1/2 × 12 × d₂ to verify. LHS = 96 Taking RHS, → 1/2 × 12 × d₂ → 1/2 × 12 × 16 → 6 × 16 → 96 RHS = 96 LHS = RHS Hence, verified. |

6. Which are the factors of x2 - 5x - 6?(1) (x + 3)(x + 2) (2) (x-6)(x + 1)(3) (x + 6) (x - 1)(4) (x - 3)(x - 2) |
|
Answer» Answer: Given equation x2 + 5x + 6 Let us try factorizing this polynomial using splitting the middle TERM method. Factoring polynomials by splitting the middle term: We need to find TWO numbers ‘a’ and ‘B’ such that a + b =5 and AB = 6. On solving this we obtain, a = 3 and b = 2 Thus, the above expression can be written as: x2 + 5x + 6 = x2 + 3x + 2x + 6 = x(x + 3) + 2(x + 3) = (x + 3)(x + 2) Thus, x+3 and x+2 are the factors of the polynomial x2 + 5x + 6.
