13. A certain sum of money is invested at acertain fixed rate compounded yearly. If theinterest accrued in two years be 44% of thesum borrowed, find the rate of compoundinterest |
|
Answer» Answer: the RATE of compound interest = 20% PER Annum Step-by-step explanation: A certain sum of money is invested at a certain fixed rate compounded YEARLY. If the interest accrued in two years be 44% of the sum BORROWED, find the rate of compound interest Let say Sum of Money Invested = P Interest Rate = R % Per annum Compound Interest after 2 years = P(1 + R/100)² - P Interest = (44/100)P = 0.44P => P(1 + R/100)² - P = 0.44P => P(1 + R/100)² = 1.44P => (1 + R/100)² = 1.44 => (1 + R/100) = 1.2 => R/100 = 0.2 => R = 20 the rate of compound interest = 20% Per Annum |

The mth term of an A.P is n and the nth term of an A.P is m. The rth term |
|
Answer» Heya mate..... ✨✨❤ Here's ur answer : »» Let a and d RESPECTIVELY be the first term and the COMMON difference of an A.P. According to the given conditions, a + (m-N)d = n ------(1) a + (n-1)d = m ------(2) On solving eqn (1) & (2) , we get, » d = -1 ; a = m+n-1 Therefore, »» rth term = a+(r-1)d .°. » rth term = (m+n-1) - (r-1) .°. » rth term = m+n-r ,, »» Hope it helps !!! «« Plz!

If the ordered pairs (a +2,4) and (5,2a + b) are equal then (a,b) is(1(2.-2) (2) (5.1)(3) (2,3)(4) (3,-2) explain it |
|
Answer» Answer: Answer is (4) part. EXPLANATION : If ordered PAIRS are EQUAL, then there domain and range are ALSO equal. So, a+2=5 So, a=5-2 a=3 Now 4=2a+b Putting the value of a, we GET; 4=3×2+b So,4=6+b Therefore b=-2. HOPE IT IS HELPFUL! ☺️☺️☺️ |

Answer» Answer: Step-by-step explanation: Let the number be 10x+y..... Also as said in your question 10y+x =(5/6)(10x+Y) And x - y = 1........ 6(10y+x)=5(10x+y) 60y+6x=50x+5y 55y = 44x 5y=4x 5(x-1)=4x (since x-y=1) 5x - 5=4x x=5 y=4 So number is 10x + y=5(10)+4=54 Do you THINK why I have not taken y-x=1...... I took x-y=1....... What could be wrong here?...... It's a good way of learning to learn concepts and then apply yourself to the question...... I told the concepts....

in the given triangle pqr ,angle QPR is equal to 90 PQ is equal to 24 cm is equal to 26 cm in triangle pqr ,angle pqr is equal to 90 and PR is equal to 8 cm find pk |
|
Answer» In the right triangle ∆ PQR, by applying Pythagoras theorem we get : PR = Similarly, In right angled ∆ PKR, by applying Pythagoras theorem we GET : PR² = PK² + KR² Or, PK² = PR² - KR² Or, PK² = 10² - 8² Or, PK² = 36 Or, PK² = 6² Or, PK = 6 THUS, WE CAN SAY THE LENGTH OF PK IS 6 cm. |

एक पतंग तीन भिन्न-भिन्न शेडों (shades) के कागजों से बनी है। इन्हें आकृति 12.17 में I,II और III से दर्शाया गया है। पतंग का ऊपरी भाग 32 cm विकर्ण का एक वर्ग है और निचला भाग 6 cm, 6 cm और 8 cm भुजाओं का एक समद्विबाहु त्रिभुज है। ज्ञात कीजिए कि प्रत्येक शेड का कितना कागज प्रयुक्त किया गया है। |
|
Answer» Answer: शेड I का कागज प्रयुक्त किया गया है = 256 सेमी²शेड II का कागज प्रयुक्त किया गया है = 256 सेमी²शेड III का कागज प्रयुक्त किया गया है = 17.92 सेमी²Step-by-step EXPLANATION: चूंकि पतंग एक वर्ग के आकार में है। वर्ग के प्रत्येक विकर्ण की लंबाई (AD & BC) = 32 सेमी (दिया है) हम जानते हैं कि एक वर्ग के विकर्ण परस्पर एक दूसरे को समकोण पर समद्विभाजित करते हैं। OA = OD = ½ AD = ½ × 32 = 16 सेमी भाग 1 का क्षेत्रफलत्रिभुज ∆ABC का क्षेत्रफल = ½ × आधार × ऊंचाई = ½ × BC × AO = ½ × 32 × 16 = 16 × 16 = 256 सेमी² भाग I त्रिभुज ∆ABC का क्षेत्रफल = 256 सेमी²इसी प्रकार, भाग II त्रिभुज ∆BDC का क्षेत्रफल = 256 सेमी²भाग III∆DEF में, माना, DE (a ) = 6 सेमी, DE(b) = 6 सेमी & EF (c) = 8 सेमी त्रिभुज ∆DEF का अर्द्ध परिमाप, s = (a + b + c)/2 s = (6 + 6 + 8)/2 cm = 20/2 s = 10 सेमीहीरोन के सूत्र से, त्रिभुज ∆DEF का क्षेत्रफल , A = √[s (s - a) (s - b) (s - c)] A = √[10(10 – 6) (10 – 6) (10 – 8) ] A = √[10 × 4 × 4 × 2] A =√[2 × 5 × 4 × 4 × 2 ] A =√[(2 × 2) × (4 × 4) × 5] A = 2 × 4√5 A = 8√5 A = 8 × 2.24 [√5= 2.24...] A = 17.92 सेमी² भाग III , त्रिभुज ∆DEF का क्षेत्रफल ,A = 17.92 सेमी²अतः , शेड I का कागज प्रयुक्त किया गया है = 256 सेमी²शेड II का कागज प्रयुक्त किया गया है = 256 सेमी²शेड III का कागज प्रयुक्त किया गया है = 17.92 सेमी²आशा है कि यह उत्तर आपकी मदद करेगा। इस पाठ से संबंधित कुछ और प्रश्न : दो विभिन्न रंगों के कपड़ों के 10 त्रिभुजाकार टुकड़ों को सीकर एक छाता बनाया गया है। ( देखिए आकृति 12.16)। प्रत्येक टुकड़े के माप 20 cm, 50 cm और 50 cm हैं। छाते में प्रत्येक रंग का कितना कपड़ा लगा हैं? एक समचतुर्भुजाकार घास के खेत में 18 गायों के चरने के लिए घास है। यदि इस समचतुर्भुज की प्रत्येक भुजा 30 m है और बड़ा विकर्ण 48 m है, तो प्रत्येक गाय को चरने के लिए इस घास के खेत का कितना क्षेत्रफल प्राप्त होगा? |
