A motorboat covers a certain distance down stream in a river in 5 hours. It covers thesame distance upstream in 5 1/2 hours. If the speed of the stream is 1.5 Kmph . Findthe speed of the boat. |
|
Answer» Answer: Step-by-step EXPLANATION: LET the speed of boat be x Speed upstream = x-1.5 Speed downstream = x+1.5 Since the upstream and downstream DISTANCE is same. (x+1.5)5 = (x-1.5)5.5 5X + 1.5*5 = 5.5x - 1.5*5.5 5.5x - 5x = 1.5*5.5 + 1.5*5 0.5x = 1.5*10.5 x = 1.5*10.5/0.5 x = 3*10.5 = 30.5 Speed of boat = 30.5 km/hr |

Answer» Question should be:ANSWER:
GIVEN:
TO PROVE:
SOLUTION:LET n be any positive integer which is divided by 4 we GET some quotient 'q' and remainder 'r' => n = 4q+r. .....(i) Where r = 0, 1 ,2 ,3 Putting r = 0 in eq(i) => n = 4q (Which is even) Putting r = 1 => n = 4q+1. (Which is odd) Putting r = 2 => n = 2(2q+1) ..(which is even) Putting r = 3 => n = 4q+3 (which is odd) Here any odd positive integer is in the form of 4q+1 , 4q+3 for some positive integer q. |

Mean proortional between 4.5 and .045 |
|
Answer» Answer: Let us start by defining what we MEAN by the proportion. The equality of any two ratios is called a proportion. For EXAMPLE, if we have any FOUR numbers or quantities that we represent as ‘a’, ‘b’, ‘c’, and ‘d’ respectively, then we may write the proportion of these four quantities as:  a:b = c:d or a:b :: c:d. From this, we will now DEFINE the proportionals. Let us BEGIN by defining the fourth proportional. |
