b)The perimeter of a rectangle is 130 cm. The length is 5cm more than the breadth. The length and breadth are? |
Answer» ANSWER :
Given :
To find :
Solution :Given the length is 5cm more than the breadth so,
Given perimeter of rectangle is 130cm As we know that
where l is length x + 5cm , b is breadth xcm and perimeter is 130cm ⇢ perimeter of rectangle = 2(length + breadth) ⇢ 2(x + 5 + x) = 130 ⇢ 2(5 + 2x) = 130 ⇢ 10 + 4x = 130 ⇢ 4x = 130/10 ⇢ 4x = 120cm ⇢ x = 120/4 ⇢ x = 30cm Breadth is 30cm
Verification :
⇢ 2(35 + 30) ⇢ 2 (65) ⇢ 130cm |

A company produces cars at three different plants in amounts x, y and z, respectively,producing an annual revenue of f(x, y, z) = x2yz − 2(x + y + z). The company is toproduce 100 units annually. How should the production be distributed to maximizethe revenue? Solve this problem by using the Lagrange multiplier method. |
|
Answer» (a) The unit sale prices of x,y and z are respectivelyRs.2.50,RS.1.50 and Rs.1.00. Total revenue in market I can be represented as: [10000200018000]⎣⎢⎢⎡2.501.501.00⎦⎥⎥⎤ =10000×2.50+2000×1.50+18000×1.00 =25000+3000+18000 =46000 Total revenue in market II can be represented as: [6000200008000]⎣⎢⎢⎡2.501.501.00⎦⎥⎥⎤ =6000×2.50+20000×1.50+8000×1.00 =15000+30000+8000 =53000 So, the total revenue in market I is Rs 46000 and in market II is Rs.53000. (B) The unit cost prices of x,y and z are respectively given as Rs.2.00, Rs. |

What's the Error? Kate has made 20 free throws in basketball games this year. That is 80% of the free throws she has attempted. To find the total number of free throws she attempted, Kate wrote the equation 80/ 100 = N /20 . What error did Kate make? |
|
Answer» Answer: Total Free Throws Attempted = 25 Step-by-step explanation: From the STATEMENT we can say: 20 free throws is 80% of the total attempted 80% to decimal is: 80/100 = 0.8 If total attempted is N, we can say: 20 is 80% (0.8) of N We can now write an ALGEBRAIC equation: 20 = 0.8N We SIMPLY solve this for X, that is the number of free throws she attempted: 20 = 0.8N N= 20/0.8 N=25 Kate attempted 25 free throws in total. Kate WROTE the equation 80/ 100 = N /20 .It is wrong. It will be 80/100=20/N Hope it helps. Thanks my answer. Mark as brainliest. |

If angles of the triangle are in rhe ratio of 2:3:4. find the value of each angle |
Answer» Answer :-
Step-by-step explanation:To Find :-
Solution: Given that,
Assumption: Let us ASSUME all the UNKNOWN ratio angles of triangle as 2X, 3x and 4x. As we know that, Sum of all interior angles of triangle = 180°, Therefore,
=> 5x + 4x = 180 => 9x = 180 => x = 180/9 => x = 20 The value of x is 20. Now, The angles of triangle are :- The angle which we assumed as 2x, => 2x => 2*20 => 40° The angle which we assumed as 3x, => 3x => 2*30 => 60° The angle which we assumed as 4x, => 4x => 4*20 => 80° Hence,

Q8 Find the sum of the sides of an equilateral triangle with side (2x + 3y - 8). |
Answer» Given:An equilateral triangle with
What To Find:We have to find the sum of SIDES of the equilateral triangle. How To Find:To find the sum of sides of the equilateral triangle we know that, All sides of equilateral triangle are equal. Solution:As we know that, ⇒ All sides of equilateral triangle are equal. So it will be, ⇒ (2x + 3y - 8) + (2x + 3y - 8) + (2x + 3y - 8) Remove the BRACKETS, ⇒ 2x + 3y - 8 + 2x + 3y - 8 + 2x + 3y - 8 Rearrange the LIKE terms, ⇒ 2x + 2x + 2x + 3y + 3y + 3y - 8 - 8 - 8 Solve the first term, ⇒ 6x + 3y + 3y + 3y - 8 - 8 - 8 Solve the second terms, ⇒ 6x + 9y - 8 - 8 - 8 Solve the third terms, ⇒ 6x + 9y - 24 ∴ So, the sum of the side of the equilateral triangle is 6x + 9y - 24. |
