Divide 5500 in two parts such that 5% of first is equal to the 10% of the second.by linear equation |
|
Answer» Step-by-step explanation: suppose X and y are TWO divided parts of 4500. then x+y=4500 __ (1) given 5% of x = 10% of y 1005x=10010y x=2y 2y+y=4500 3y=4500 y=1500 x+1500=4500 x=4500−1500 x=3000 hence the 4500 is been divided into two parts of 1500 and 3000. |

The cost of 1 m cloth is Rs 44 4/5.Find the cost of 3 3/4 m of cloth |
|
Answer» Answer: Length of cloth NEEDED for stitching 1 shirt=2 m 15 cm =2 m+15 cm =2×1 m+15 cm =2×100 cm+15 cm (SINCE 1 m=100 cm) Length of cloth needed for stitching 1 shirt=200+15=215 cm Total length of cloth available=40m since 1 m=100 cm Total length of cloth available=40×100cm Total length of cloth available=4000cm Total NUMBER of shirts can be MADE from available cloth = Lengthofclothneededfor1shirt Totallengthofclothavailable
Total number of shirts can be made from available cloth= 215 4000
Quotient=18 and Remainder=130 ∴ number of shirts that can be made=18 and remaining cloth=130 cm =100 cm+30 cm since 1 m=100 cm Remaining cloth=1 m30 cm |

P(x) is a polynomial that satisfy the relation p(x+2) = x^2-6x+2, then find p(x). |
|
Answer» P(x) = x² - 10x + 18 Step-by-step explanation: p(x+2) = x² - 6X + 2 but. ..we can write that... x² - 6x + 2 = (x + 2)² - 10 ( x + 2 ) + 18 hence.... P(x) = x² - 10x + 18 |

Factorise 2x^2+4x+1 |
|
Answer» I see most of the answers here somehow ‘magically’ do a substitution/grouping the elements together without a CLEAR explanation why he/she does so. It seems more or less guessing without a definite way to factorise this. I will show you a small trick I learned several years ago. If you have a calculator, you can easily find the roots of the EQUATION x4+4x3+2x2−4x+1=0 . They are (In this case I use but most advanced calculators have the ability find the roots of a given equation) You may OBSERVE that -2.4142 + 0.41421 = -2 and -2.4142 × 0.41421 = -1 (I round up because the roots are approximate). Recall Vieta's formulas, these two roots are also the roots of the quadratic equation x2+2x−1=0 . Therefore, the EXPRESSION x4+4x3+2x2−4x+1 can be EXPRESSED as a product of x2+2x−1 . By grouping the elements appropriately, you will get: x4+4x3+2x2−4x+1 =(x4+2x3−x2)+(2x3+4x2−2x)+(−x2−2x+1) =x2(x2+2x−1)+2x(x2+2x−1)−(x2+2x−1) =(x2+2x−1)(x2+2x−1) =(x2+2x−1)2 Bear in mind, this technique only works if the 4th degree polynomial is a product of two 2nd degree polynomials and one of them must have real roots. |

(ii) A car covers a distance of 270 kms with some speed. If the speed isdecreased by 10 km/hr, it will take 54 minutes more to cover the samedistance. Find the original speed of the car.(solve) |
|
Answer» Let the speed of CAR is x. Speed of carbon speed is DECREASED by 10 Km/hour = x-10. = 270/x-10 - 270/x =54/60. = 1/x-10 - 1/x = 54/60 X 270. = x-x + 10/x(x-10) = 1/300 = 10 X 300 = x^2 - 10 x = x^2 - 10 x -3000 = 0 = x^2 - 60 +50x-3000=0 = x (x-60) +50(x-60)=0 = (x-60) (x+50) = 0 THEREFORE, (x-60)=0 So , x= 60 km/h |

|
Answer» Step-by-step EXPLANATION: ধরি , একটি কলমএর মূল্য y টাকা একটি বইয়ের মূল্য Z টাকা y+z= ৯৫ y= ৯৫-z ১৫ টাকা বেশি অর্থাৎ y+১৫ বইটির মূল্য ১৪ টাকা কম অর্থাৎ z-১৪
y+১৫ = ২(z-১৪) y+১৫ = ২z-২৮ ৯৫-z+১৫ = ২z-২৮ ১১০-z-২z+২৮ = ০ ১৩৮-৩z =০ -৩z = -১৩৮ ৩z = ১৩৮ z = ৪৬ বইটির মূল্য ৪৬ টাকা। কলমটির মূল্য (৯৫-৪৬) টাকা। = ৪৯ টাকা। |

In the adjoining figure if AB // CD then find x, y, z.CeP3x23►DAs180►BQR |
|
Answer» Given, AB II CD PQR is a triangle ️. To find : x, y, z Solution : Since AB II CD, THUS, Angle DPQ + Angle RQP = 180⁰ ( SUM of co-intererior angles on the same side of TRANSVERSAL in a parallel LINES is 180⁰) => 2x⁰ + 3x⁰ + 80⁰ = 180⁰ => 5x⁰ = 180⁰ - 80⁰ 100 100=> x = ------ = 20⁰ 100=> x = ------ = 20⁰ 5
Thus, Angle QPR = 2x = 40 in triangle PQR, ANGLE (PQR +QPR+RPQ) = 180⁰ ( angle sum property) => 80⁰ + y⁰ + 40⁰ = 180⁰ => y⁰ + 120⁰ = 180⁰ => y⁰ = 180⁰ - 120⁰ = 60⁰ Now, y⁰ + z⁰ = 180⁰ ( linear pair) thus, 60⁰ + z⁰ = 180⁰ thus, z = 180 - 60 = 120⁰ |
