Answer» Answer: We KNOW that (a + b)² = (a - b)² + 4ab Here • a + b = 2 • a - b = 10 By substituting the values ⇒ (2)² = (10)² + 4ab ⇒ 4 = 100 + 4ab ⇒ 4 - 100 = 4ab ⇒ - 96 = 4ab ⇒ - 96/4 = AB ⇒ - 24 = ab ⇒ ab = - 24 We know that (a + b)² = a² + b² + 2ab Here • a + b = 2 • ab = - 24 By substituting the values ⇒ (2)² = a² + b² + 2(-24) ⇒ 4 = a² + b² - 48 ⇒ 4 + 48 = a² + b² ⇒ 52 = a² + b² ⇒ a² + b² = 52 Therefore the VALUE of a² + b² is 52 and the value of ab is - 24 |

Two solution of milk and water are kept in two vessels A and B.the ratio of quantity of milk in vessels A and B is 4:5 while the ratio of quantity of water in vessels A and B is 8:9. it is known that the concentration of milk in one of these vessels between 60%and 80%.what could be the concentration of milk in other vessels. |
|
Answer» Answer: 54%< CONCENTRATION of milk in other vessel < 88.89% Step-by-step EXPLANATION: Ratio of milk = 4 X : 5x Ratio of water = 8 y : 9 vessel A milk to water ratio = 4x /8y = x/2y vessel B milk to water ratio = 5x /9y vessel A milk concentration in percentage vessel B milk concentration in percentage In any of the one vessel milk concentration is between 60 % and 80 % from vessel A to B Multiply by 10/9 {x/2y * 10/9 = 5x /9y} Concentration In Vessel B from vessel B to A Multiply by 9/10 {5x/9y *9/10 = x/2y} Concentration in vessel A Since we don't know given concentration percentage of milk for whether vessel A or B , we write what could be the possible range satisfying both condition. 54%< concentration of milk in other vessel < 88.89% |
