a cottage industry produce a certain number of pottery articles in a day it observed on a particular day that the cost of production of each article (in rupee) was 3 more than twice the number of article produced on that day if total cost of production on that day was rupee 90 find the number of articles produced and cost of each article |
|
Answer» ong>Answer: 15 RUPEES Step-by-step explanation: We know that Total COST of production = Number of articles PRODUCED × Cost of article Given total cost of production =Rs.90 and Cost of production of each article (in rupees) was 3 more than TWICE and number of articles produced on that day Let the number of articles =x Hence, Cost of article =2x+3 Now, Total cost of production = Number of articles produced × Cost of article 90=x(2x+3) 2x 2 +3x−90=0 2x 2 +15x−12x−90=0 x(2x+15)−6(2x+15)=0 (x−6)(2x+15)=0 x=6, 2 −15
But x cannot be negative as number of articles is not negative Hence, x=6 ∴ Number of articles =6 And Cost of article =2x+3 =2(6)+3 =12+3 =Rs.15 |

The anglees of a quadrilateral are in the ratio 4:5:3,the difference between greatest angle and least angle is 42degree.Find all angles |
|
Answer» Given :- Ratio of angles of a quadrilateral = 4 : 5 : 3 Difference between greatest angle and the LEAST angle = 42° To FIND :-The value of all angles of the quadrilateral. Analysis :-Consider the common ratio as x and let the angles be 4x, 5x and 3x respectively. According to the question, make an EQUATION by showing it's difference. Solve x and substitute them to get the angles. Subtract the angles we got from the total angle of a quadrilateral to get the 4th one. Solution :-Let us consider the common ratio to be x Then the angles would be 4x, 5x and 3x respectively. Given that, The difference between greatest angle and least angle is 42° According to the question, Hence, the value of x is 21 Then, the angles of the quadrilaterals would be Sum of the angles = 84 + 105 + 63 = 252° Finding the fourth angle, Fourth angle = Therefore, the angles are 84°, 105°, 63° and 108° respectively. |

Find the value of x3 + y3 + z3 – 3xyz if x2 + y2 + z2 = 83 and x + y + z = 15 |
|
Answer» ong>Answer: GIVEN = x² + y² + z² = 83 AND x + y + z = 15 TO FIND = x³ + y³ + z³ - 3xyz SOLUTION ( x + y + z )² = x² + y² + z² + 2 ( XY + yz + zx ) AND x + y + z = 15 SO, 83 + 2 ( xy + yz + zx ) = (15)² 83 + 2 ( xy + yz + zx ) = 225 2 ( xy + yz + zx ) = 225 - 83 2 ( xy + yz + zx ) = 142 ( xy + yz + zx ) = 142/2 ( xy + yz + zx ) = 71 AGAIN x³ + y³ + z³ - 3xyz = ( x + y + z ) [ ( x²+ y² + z² ) - ( xy + yz + zx ) ] OR, = 15 × [ 83 - 71 ] = 15 × 12 = 180 HERE'S YOUR ANSWER PLEASE MARK ME AS BRAINLIEST ♥️ |
