The problem presents a pattern involving two numbers connected by a symbol '◆' and resulting in three numbers. We need to identify the mathematical operations that transform the initial two numbers into the three resulting numbers. Once the pattern is identified, we apply it to the final set of numbers to find the missing values.
\(25 \text{ ◆ } 64 = 5 \text{ ; } 8 \text{ ; } 13\)
Let's examine the relationship between \(25\), \(64\) and \(5\), \(8\), \(13\).
So, the pattern seems to be: \(\sqrt{\text{First Number}}\text{ ; } \sqrt{\text{Second Number}}\text{ ; } (\sqrt{\text{First Number}} + \sqrt{\text{Second Number}})\).
\(144 \text{ ◆ } 36 = 12 \text{ ; } 6 \text{ ; } 18\)
The pattern holds true for the second example.
\(121 \text{ ◆ } 81 = ? \text{ ; } ? \text{ ; } ?\)
Therefore, the missing numbers are \(11 \text{ ; } 9 \text{ ; } 20\).
Correct Option: B) 11; 9; 20
This problem involves the relationship between speed, distance, and time. When the distance traveled is constant, speed and time are inversely proportional. We are given the ratio of speeds for three cars and need to find the ratio of the times taken to cover the same distance.
Understand the relationship between speed, distance, and time: The fundamental formula is:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]Apply the constant distance condition: Since the distance is the same for all three cars, we can rearrange the formula to express time:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]This shows that if the distance is constant, time is inversely proportional to speed. That is, if \(S_1, S_2, S_3\) are the speeds and \(T_1, T_2, T_3\) are the times, then:
\[ T_1 : T_2 : T_3 = \frac{1}{S_1} : \frac{1}{S_2} : \frac{1}{S_3} \]Write down the given speed ratio: The speeds of the three cars are in the ratio \(S_1 : S_2 : S_3 = 2 : 3 : 4\).
Find the inverse ratio for time: The ratio of the times taken will be:
\[ T_1 : T_2 : T_3 = \frac{1}{2} : \frac{1}{3} : \frac{1}{4} \]Convert the fractional ratio to a whole number ratio: To eliminate the fractions, multiply each term by the Least Common Multiple (LCM) of the denominators (2, 3, 4). The LCM of 2, 3, and 4 is 12.
\[ T_1 : T_2 : T_3 = \left(\frac{1}{2} \times 12\right) : \left(\frac{1}{3} \times 12\right) : \left(\frac{1}{4} \times 12\right) \]\[ T_1 : T_2 : T_3 = 6 : 4 : 3 \]B) 6 : 4 : 3 is the correct ratio of the times taken by the cars.
The question asks for the term describing the process where heavier insoluble components in a mixture of water and insoluble substances settle down. This is a fundamental concept in chemistry and physics related to separation techniques.
Correct Option: D) sedimentation is the process where heavier, insoluble particles in a liquid mixture settle down at the bottom due to gravity.
