Find the common solution of following inequality (x-7)(x-15) |
|
Answer» Step-by-step explanation: X - 7)(x - 15) ≤ 0 , (x - 2)(x -8)(x - 12) ≥ 0 find solution for (x - 7)(x - 15) < 0 first replace inequality sign by equal e.g., (x - 7)(x - 15) = 0 , x = 7, 15 now, put 7 and 15 in number line . And apply the condition of inequality , we GET 7 < x < 15 Similarly find the solutions of (x - 2)(x - 8)(x - 12) ≥ 0 replace inequality by equal And we get x = 2, 8, 12 now put it in number line. apply condition we get , 2 ≤ x ≤ 8 or, x ≥ 12 Now, take common solution of it USING all numbers { e.g., 2, 7, 8, 12, 15} in number line . see attachment , we get the solution x ∈(7, 8] ∪ [12, 15) |

Sand and gravel are mixed in the ratio 5:3 to form ballast.How much gravel is mixed with 750 KG of sand?How much sand is mixed with 750 KG of gravel? |
|
Answer» Answer: 450 KG of gravel is mixed 750 Kg of SAND. In 750 Kg of gravel, 1050 Kg sand will be mixed. Step-by-step explanation: If the ratio is 5:3 for sand and gravel. i.e. 5/3 = sand / gravel => 5 gravel = 3 sand This shows that with 5 parts of gravel, 3 parts of sand is mixed. => 5(X) = 3(750kg) => x = 3(750kg) / 5 => x = 3(150kg) => x = 450kg Hence 450 Kg of gravel is mixed 750 Kg of sand. From here by subtracting 750 kg of sand with 450 kg of gravel , we can see that, in a MIXTURE of of sand and gravel, sand is 300 kg more than gravel. Thus in 750 Kg of gravel, 1050 Kg sand will be mixed |

A steamer goes downstream from one port to another in 9 hours. It covers the same distance upstream in 10 hours. If the speed of stream be 1 km/h, find the speed of the steamer in still water. Also find the distance between the ports. asap plsssss |
|
Answer» Let the speed of the steamer in still water is x km/h and distance is d. Then, speed of steamer downstream (u)= speed of steamer in still water+speed of stream=x+1 Speed of steamer upstream (v)=speed of steamer in still water-speed of stream=x−1 Distance covered by steamer upstream (d)=10(x−1) ......(1) Distance covered by steamer downstream (d)=9(x+1) ......(2) From EQUATION (1) and (2), 10(x−1)=9(x+1) 10x−10=9x+9 10x−9x=9+10 x=19 km/h Substituting this value in equation(1), Distance(d)=10(19−1)=180km Hence, the speed of the steamer in still water is 19km/h and the distance between the ports is 180km.
