The digit in in tens place of two digit number is more than its digit in the the units place by 5 the sum of of its digit is 1/8 of the number. Find the number??? |
Answer» ANSWER :72 Solution :Let the tens digit and the unit digit of the required two digits number be x and y respectively . Thus , The required number = 10X + y Now , According to the question , The tens digit of the required number is 5 more than its unit digit . Thus , x = y + 5 ----------(1) Also , It is given that , The sum of both the digits of the number is ⅛ of the number . Thus , => x + y = ⅛ of (10x + y) => x + y = ⅛•(10x + y) => 8(x + y) = 10x + y => 8x + 8y = 10x + y => 8x + 8y - 10x - y = 0 => 7y - 2X = 0 ----------(2) Now , Putting x = y + 5 in eq-(2) , we get ; => 7y - 2x = 0 => 7y - 2(y + 5) = 0 => 7y - 2y - 10 = 0 => 5y - 10 = 0 => 5y = 10 => y = 10/5 => y = 2 Now , Putting y = 2 in eq-(1) , we get ; => x = y + 5 => x = 2 + 5 => x = 7 Hence ,The required number is 72 . |

16÷80 how to divide |
|
Answer» Answer: 16÷80=0.2 Step-by-step explanation: Instead of SAYING 16 divided by 80 equals 0.2, you could just use the division SYMBOL, which is a slash, as we did above. Also note that all answers in our division calculations are rounded to THREE DECIMALS if necessary. Here are some other ways to display or communicate that 16 divided by 80 equals 0.2: 16 ÷ 80 = 0.2 16 over 80 = 0.2 16⁄80 = 0.2 The easiest way we found to answer the question "what 16 divided by 80 means", is to answer the question with a question: How many times does 80 go into 16? |

Find a quadratic polynomial the sum and product of whose zeroes are -3and 2 respectively |
Answer» Answér :x² + x - 6 Note:★ The possible VALUES of the VARIABLE for which the polynomial BECOMES zero are called its zeros . ★ A quadratic polynomial can have atmost two zeros . ★ The general form of a quadratic polynomial is given as ; ax² + bx + c . ★ If α and ß are the zeros of the quadratic polynomial ax² + bx + c , then ; • Sum of zeros , (α + ß) = -b/a • Product of zeros , (αß) = c/a ★ If α and ß are the zeros of a quadratic polynomial , then that quadratic polynomial is given as : k•[ x² - (α + ß)x + αß ] , k ≠ 0. ★ The discriminant , D of the quadratic polynomial ax² + bx + c is given by ; D = b² - 4ac ★ If D = 0 , then the zeros are real and equal . ★ If D > 0 , then the zeros are real and distinct . ★ If D < 0 , then the zeros are unreal (imaginary) . Solution :Here , It is given that , -3 and 2 are the zeros of the required quadratic polynomial . Thus , Let α = -3 and ß = 2 Now , Sum of zeros of the required quadratic polynomial will be ; α + ß = -3 + 2 = -1 ALSO , Product of zeros of the required quadratic polynomial will be ; αß = -3×2 = -6 Thus , The required quadratic polynomial polynomial will be ; => k•[ x² - (α + ß)x + αß ] => k•[ x² - (-1)x + (-6) ] => k•[ x² + x - 6 ] For k = 1 , the polynomial will be ; x² + x - 6 Hence ,Required answer is : x² + x - 6 |
