|
Answer» Answer: MATHS If 460 is divided by a NATURAL number, quotient is 6 more than five times the divisor and remainder is 1. Find quotient and divisor December 20, 2019avatar Ashi Chandrasekaran SHARE ANSWER Let the Divisor be X. Then the Quotient = 5X+6 DIVIDEND = 460 Remainder = 1 We know that, Dividend = Divisor × Quotient + Remainder 460 = X × (5X+6) + 1 460 = 5X²+6X+1 5X²+6X-459 = 0 5X²+51X-45X-459 = 0 X(5X+51)-9(5X+51) = 0 (X-45) (5X+51)= 0 (X-9)= 0 OR(5X-51) = 0 (X-9) = 0 X = 9 Divisor = X = 9 And, Quotient = 5X +6 = 5 × 9 + 6 = 51. |

2 men and 5 boys can finish a piece of work in 4 days while 3 mens and 6 boys can finish it in 3 days . find the time taken by one man alone to finish the work and taken by one boy alone to finish the work |
|
Answer» ANSWER: Total time taken by one man to complete the job = 18 DAYS Step-by-step explanation: Let one man complete the work in 1/x days and one boy completes the work in 1/y days. Now, 2 men and 5 BOYS can finish a piece of job in 4 days ⇒ 2x + 5Y = 1/4 ⇒ 8x + 20y = 1 .........(1) Also, 3 men and 6 boys finish it in 3 days ⇒ 3x + 6y = 1/3 ⇒ 9x + 18y = 1 ........(2) Now, solving the equations (1) and (2) We get 1/x = 18 and 1/y = 36 So, Total time taken by one man to complete the job = 18 days |

Three friends had a total of 'N' Rupees. If the first one had Rs. 7,000 more than the third and the third one had Rs. 9.000 less than the second one, what is the value of ne?Statements:L. The second friend had Rs. 27.00011. The third and the second friend, together had a total of Rs. 45,000Select one:a. Statement i alone is sufficient to answer the questionO b. Statement il alone is sufficient to answer the questionEither statement alone is sufficient to answer the question,O d. Both the statements together are not sufficient to answer this question |
|
Answer» Solution :- LET us assume that, second FRIEND had RS.x . So, → Third friend had = 9000 less than the second one = Rs.(x - 9000) and, → First friend had = Rs.7000 more than the third = (x - 9000) + 7000 = Rs.(x - 2000) Statement 1) :-
then, Putting x = Rs.27,000 we get, → (x - 2000) + x + (x - 9000) = N → 3x - 11000 = N → 3 * 27000 - 11000 = N → 81000 - 11000 = N → N = Rs.70,000 . Conclusion :-
Statement 2) :-
so, → Third friend + second friend = 45000 → (x - 9000) + x = 45000 → 2x = 45000 + 9000 → 2x = 54000 → x = Rs.27,000 then, Putting x = Rs.27,000 we get, → (x - 2000) + x + (x - 9000) = N → 3x - 11000 = N → 3 * 27000 - 11000 = N → 81000 - 11000 = N → N = Rs.70,000 . Conclusion :-
Therefore , we can conclude that, Either statement alone is sufficient to answer the question . Learn more :- if a nine digit number 260A4B596 is divisible by 33, Then find the number of POSSIBLE values of A. if n is an integer such that 1nn352 is a six digit number |

Question :a and ß are the roots of the quadratic polynomial p(x)=x^2-(k-6)x+2(2k-1).Find the value of k,if a+ß=1/2aß.♻️Moderator™♻️Content Quality Answer Needed ✔️ |
|
Answer» <P>Correct Question: α and β are the zeroes of the quadratic polynomial p(x) = x² - ( K - 6 )x + 2( 2k - 1 ). Find the value of k, if α + β = ( 1/2 ) × αβ Answer: - 5 Step-by-step explanation: Given : α and β are the zeroes of the quadratic polynomial p(x) = x² - ( k - 6 )x + 2( 2k - 1 ). COMPARING x² - ( k - 6 )x + 2( 2k - 1 ) with ax² + bx + c we get,
Sum of zeroes = α + β = - b/a = - { - ( k - 6 ) } / 1 = k - 6 Product of zeroes = αβ = c/a = { 2( 2k - 1 ) } / 1 = 2( 2k - 1 ) Given : ⇒ α + β = ( 1/2 ) × αβ ⇒ k - 6 = ( 1/2 ) × { 2( 2k - 1 ) } ⇒ k - 6 = 2k - 1 ⇒ - 6 + 1 = 2k - k ⇒ - 5 = k ⇒ k = - 5 THEREFORE the value of k is - 5. |

Verify that a*0=0*a where a=-4/7 solve |
|
Answer» Any NUMBER multiplied by 0 is 0 for any number a. From there every PRODUCT that includes 0 is 0 (0a = 0ab = ... = 0). a0 = 0a = 0 If I'm not mistaken, then * MEANS multiply. If * means exponentiation (that's a weird syntax) then 0^a for any nonzero a, as WELL as a^0 for any nonzero a will be 0. Given that a = -4/7 ≠ 0, a^0 = 0^a If * means another operation, let me know. |

A,C and D are points on a circle of radius 4cm, centre O. BA and BC are tangents to the circle. OB = 10cm. Work out the length of arc ADC. Give your answer correct to 3 significant figures. |
|
Answer» Given : A,C and D are points on a circle of radius 4cm, CENTRE O. BA and BC are tangents to the circle. OB = 10cm. Solution: OB = 10 cm OA = OC = Radius = 4 cm Cos∠AOB = OA/OB = 4/10 = 2/5 Cos∠COB = OC/OB = 4/10 = 2/5 => ∠AOC = ∠AOB + ∠COB => ∠AOC = Cos⁻¹(2/5) + Cos⁻¹(2/5) => ∠AOC = 2 Cos⁻¹(2/5) => ∠AOC = 2 * 66.42 => ∠AOC = 132.84° if D is in minor arc then length of arc ADC. = ( 132.84°/360°) 2π (4) = 9.274 cm if D is in major arc then length of arc ADC. = ( (360° -132.84°)/360°) 2π (4) = 15.859 cm Learn more: Which has greater degree measure : an arc of length 5cm of circle of ...
