Keep learning, keep growing, and keep believing in yourself. Best wishes, JSunil Sir Find the ratio in which line y = x divides the line segment joining the points (6, 3) and (1, 6) Step 1: Let's assume the ratio in which the line divides the segment AB is 𝒌: 𝟏 Step 2: Find the coordinates of the point of intersection P as x = (𝒌+𝟔)/( k + 1); y = (𝟔𝒌 – 3)/(k + 1) Step 3: The point P lies on the line Y = X, so you equated the x-coordinate and the y-coordinate of point P So, P(x, y) lies on y = x k + 6 = 6k –3 k = 𝟗 /𝟓 Ratio is 9 : 5 More related material Class 10 chapter Co-Ordinate
sum of integers between 100 and 200Â (i) divisible by 9 (ii) not divisible by 9 (CBSE 2024) Class 1015/8/2023 Find the sum of integers between 100 and 200 which are (i) divisible by 9 (ii) not divisible by 9 (5 mark question CBSE BOARD 2023 - 24) You can apply formula of nth term aₙ = a + (n - 1)d to find number of terms(n) then , Apply formula of sum of nth term Sn= n/2 (a + l)d to find Sum of n terms(Sn) Thus, you may find result for question of board paper 2024 the sum of integers between 100 and 200 which are (i) divisible by 9 (ii) not divisible by 9 (a) The integers between 100 and 200 that are divisible by 9 are 108, 117, 126,.......,198 Here a = 108,d = 9 ,l = 198aₙ = a + (n - 1)d So, 198 = 108 + (n - 1)9 n = 11 then , Sn = n/2[ a + l ] So, S = 11/2[108+198] = 1683 (b) All integers between 100 and 200 are 101, 102, 103,...........,199. a = 101 , d =1 , l = 199 aₙ = a + (n - 1)d 199 = 101 + (n - 1)1 n = 99 Now, S = n/2[ a + l ] = 99/2[101 + 199] = 14850 For final answer Sum of the integers between 100 and 200 that are not divisible by 9 = (Sum of the integers between 100 and 200) - (sum of the integers between 100 and 200 that are divisible by 9) = 14850 - 1683 = 13167 3.You can now try to solve these Related Questions and put your solution in comment box 1.

This is the most confusing question related to class 8 science chapter sound Q.will sound wave having frequency of 144Hz and 240Hz produce a musical sound?Why? Jsunil sir blog Visit , comment and subscribe www.Jsuniltutorial.in Correct answer is: Yes , sound wave having frequency of 144Hz and 240Hz produce a musical sound because musical notes is produced by a combination of frequencies which are in a simple ratio of whole number with each other . Class 09 Chapter sound Examples : Sound of frequencies of 261.62Hz,523.24hz and 784.86Hz produced one after another produce a musical sound as they are in ratio 1:2:3 Question related to Eureka plus science book In Indian classical music, the seven main musical notes are known as "Saptak Swaras." Each of these notes is associated with a specific frequency, and they form the basis of melodies and ragas. The frequencies can vary slightly depending on the tuning system and reference pitch used, but I'll provide you with approximate frequencies for these notes: 1. Sa (Shadja) - The tonic note: Approximate Frequency: Around 220Hz (in the middle octave) 2. Re (Rishabh) - The second note: Approximate Frequency: Around 246.94Hz 3. Ga (Gandhar) - The third note: Approximate Frequency: Around 293.66Hz 4. Ma (Madhyam) - The fourth note: Approximate Frequency: Around 329.63Hz 5. Pa (Pancham) - The fifth note: Approximate Frequency: Around 392.00Hz 6. Dha (Dhaivat) - The sixth note: Approximate Frequency: Around 440.00Hz 7. Ni (Nishad) - The seventh note: Approximate Frequency: Around 493.88Hz These frequencies are based on the equal temperament tuning system and are given for the reference pitch of A4 being 440Hz. Keep in mind that in different styles of Indian classical music and different tunings, these frequencies might vary slightly. These notes and their frequencies form the foundation of Indian classical music, and melodies are created by combining these notes in various patterns and sequences. |
