A book has a total of 800 pages. If Bhushan reads 1/8th of the book daily, in how many days will he read 3/8th of book ? |
|
Answer»
After reading 3/8 of the BOOK, the remaining fraction 1 - 3/8 = 5/8 The boy then reads 4/5 of 5/8 = 4/5 x 5/8 = 1/2 Total fraction READ = 3/8 + 1/2 = 7/8 The UNREAD fraction = 1 - 7/8 = 1/8 This is equivalent to 30 pages ∴ The book has 30 ÷ 1/8 = 240 page

X=4+square root of 15 then find the value of (x+1/x) to the power 2 |
|
Answer» Notice that 4² and 15 differ by only 1. This will be USEFUL to find the INVERSE of x. → 1/x → 1/(4 + √15) → Multiply (4 - √15)/(4 - √15). → (4-√15)/(4² - 15) ∴1/x = 4 - √15 ∴x + 1/x = 8 Therefore, the answer is 8² or 64. |

|
Answer» Given : A model rocket is launched from the ground. The height h reached by the rocket after t seconds h(t)= -5t²+100t To Find : At what time the rocket is 495 feet above the ground? Solution: h(t)=-5t²+100t Let say at time = x rocket is 495 feet above the ground => h(x) = 495 h(x) = -5x² + 100X -5x² + 100x = 495 => x² - 20x = -99 => x² - 20x + 99 =0 => x² - 9x - 11x + 99 = 0 => x(x - 9) - 11(x - 9) = 0 => (x - 9) ( x - 11) = 0 => x = 9 , x = 11 rocket is 495 feet above the ground at 9 SEC & 11 sec Learn More: A body is dropped from a height h at t = 0, with zero INITIAL velocity.

8. किसी बस स्टाप को पुराने गत्ते से बने 50 खोखले शंकुओं द्वारा सड़क से अलग किया हुआहै। प्रत्येक शंकु के आधार का व्यास 40 cm है और ऊँचाई 1 m है। यदि इन शंकुओं कीबाहरी पृष्ठों को पेंट करवाना है और पेंट की दर 12 रुपए प्रति m- है, तो इनको पेंट करानेमें कितनी लागत आएगी? (= 3.14 और 1.04 = 1.02 का प्रयोग कीजिए।) |
|
Answer» Answer: दिया है : प्रत्येक शंकु के आधार का व्यास = 40 cm प्रत्येक शंकु के आधार की त्रिज्या , r = 40 /2 = 20 cm = 20/100 = 0.20 m [1 cm = 1/100 m] प्रत्येक शंकु के आधार की ऊँचाई , h = 1 m शंकु की तिर्यक ऊँचाई, l = √h² + r² ⇒ l = √1² + 0.2² ⇒ l = √1 + 0.04 ⇒ l = √1.04 ⇒ l = 1.02 m शंकु का वक्र पृष्ठीय क्षेत्रफल = πrl = (3.14 × 0.2 × 1.02) = 0.64056 m² शंकु का वक्र पृष्ठीय क्षेत्रफल = 0.64056 m² प्रति m² पेंट करने का व्यय = ₹ 12 ∴0.64056 m² पेंट करने का व्यय = ₹ 12 × 0.64056 = ₹ 7.68672 एक शंकु के पेंट करने का व्यय = ₹ 7.68672 ∴ 50 शंकुओं को पेंट करने का व्यय = ₹ 7.68672 × 50 = ₹ 384.34 अतः , 50 शंकुओं को पेंट करने में ₹ 384.34 की लागत आएगी। आशा है कि यह उत्तर आपकी मदद करेगा। इस पाठ से संबंधित कुछ और प्रश्न : एक जोकर की टोपी एक शंकु के आकार की है, जिसके आधार की त्रिज्या 7 cm और ऊँचाई 24 cm है। इसी प्रकार की 10 टोपियाँ बनाने के लिए आवश्यक गत्ते का क्षेत्रफल ज्ञात कीजिए। Step-by-step EXPLANATION: |
