Find 11 rational number between 11 / 22 and 17/22(by division method) |
|
Answer» ong>Answer: FIRST method to find rational number between two numbers: Since we have to find 5 rational numbers between 3/5 and 4/5, so we will MUTIPLY the numerator and denominator of the given numbers by 5+1, i.e. equal to 6. We get, 3 5 = 3 × 6 5 × 6 = 18 30 and 4 5 = 4 × 6 5 × 6 = 24 30 Now, we have to find 5 rational numbers between 18/30 and 24/30, which will COME as ( 19 30 ) , ( 20 30 ) , ( 21 30 ) , ( 22 30 ) , ( 23 30 ) = ( 19 3 ) , ( 2 × 10 3 × 10 ) , ( 7 × 3 10 × 3 ) , ( 11 × 2 15 × 2 ) , ( 23 30 ) = ( 19 30 ) , ( 2 3 ) , ( 7 10 ) , ( 11 15 ) and ( 23 30 )
Thus, five rational numbers between 3/5 and 4/5 are = ( 19 30 ) , ( 2 3 ) , ( 7 10 ) , ( 11 15 ) and ( 23 30 ) |

बचत की गणना कैसे होती है लोग बचत क्यों करते हैं |
|
Answer» ONG>¿ बचत की गणना कैसे होती है लोग बचत क्यों करते हैं ?
✎... बचत की गणना करने के लिए कुल आय में से कुल उपभोग का खर्चा घटाया जाता है जो शेष प्राप्त होता है, वह बचत होती है, जो कि इस प्रकार होगा... बचत = कुल आय — कुल उपभोग लोग बचत इसलिए करते हैं, ताकि वह अपने भविष्य को सुरक्षित कर सकें। जीवन अनिश्चित होता है, भविष्य में किसी भी तरह का विपत्ति अथवा संकट आ सकता है, यदि लोग जितना आज कमा रहे हैं, सारा आज ही खर्च कर दें और कुछ भी बचत नहीं करें। भविष्य में आने वाली किसी भी अप्रत्याशित स्थिति से निपटने के लिए उनके पास पर्याप्त धन नहीं होगा। यदि लोग बचत करेंगे और नियमित रूप से थोड़ा-थोड़ा धन बचाएंगे तो वे अब भविष्य में आने वाली किसी भी आकस्मिक वित्तीय संकट से जूझ सकते हैं। इसी कारण लोग अपने भविष्य को सुरक्षित करने के लिए बचत करते हैं, ताकि अपने भविष्य की आने वाली आवश्यकताओं की पूर्ति कर सकें। ○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○○ |

In Euclid's Division Lemma, when a hy + r where a, b are positive integers then what values r can take? |
|
Answer» ong>ANSWER: Euclid's division Lemma states that for any two POSITIVE integers 'a' and 'b' there exist two unique whole numbers 'q' and 'r' such that , a = bq + r, where 0≤ r < b. Here, a= Dividend, b= DIVISOR, q= QUOTIENT and r = Remainder. Hence, the values 'r' can take 0≤ r < b. Step-by-step explanation: please mark me as brainliest |

E-4 Solve any two sub question of following. in figure Z BAC = 90° seg BL, seg СMatemedians then prove that 4(BL+CM) = 5BC320M3.2Nano A |
|
Answer» Step-by-step explanation: GIVEN : ∠BAC = 90° seg BL and seg CM are the medians. To prove: 4(BL2 + CM2 ) = 5BC2 In ∆BAL, ∠BAL 90° [Given] ∴ BL2 = AB2 + AL2 (i) [Pythagoras theorem] In ∆CAM, ∠CAM = 90° [Given] ∴ CM2 = AC2 + AM2 (ii) [Pythagoras theorem] ∴ BL2 + CM2 = AB2 + AC2 + AL2 + AM2 (III) [Adding (i) and (ii)] Now, AL = 1/2 AC and AM = 1/2 AB (iv) [seg BL and seg CM are the medians] ∴ BL2 + CM2 = AB2 + AC2 + ( 1/2 AC)2 + (1/2 AB)2 [From (iii) and (iv)] = AB2 + AC2 + AC2/4 + AB2/4 = AB2 + AB2/4 + AC2 + AC2/4 = (5AB2)/4 + 5AC2/4 = BL2 + CM2 = 5/4(AB2 + AC2) ∴ 4(BL2 + CM2 ) = 5(AB2 + AC2 ) (v) In ∆BAC, ∠BAC = 90° [Given] ∴ BC2 = AB2 + AC2 (VI) [Pythagoras theorem] ∴ 4(BL2 + CM2 ) = 5BC2 [From (v) and (vi)] |
