Frequently Asked Questions
What is the formula to calculate the area of a triangle?
The area of a triangle can be calculated using the formula: Area = 1/2 base height.
If a train travels at a speed of 60 km/h, how far will it travel in 2.5 hours?
Distance = Speed Time. Therefore, the train will travel 60 km/h 2.5 hours = 150 kilometers.
What is the least common multiple (LCM) of 12 and 15?
The LCM of 12 and 15 is 60.
If a rectangle has a length of 10 cm and a width of 5 cm, what is its perimeter?
The perimeter of a rectangle is calculated as Perimeter = 2 (length + width). Thus, the perimeter is 2 (10 cm + 5 cm) = 30 cm.
In a sequence where each number is doubled, what is the 5th term if the first term is 3?
The sequence can be represented as: 3, 6, 12, 24, 48. Therefore, the 5th term is 48.
