Answer: 64
Explanation If each side of the cube is doubled in length, the new side length will be twice the original side length. Since the volume of a cube is proportional to the cube of the side length, the new volume will be: New volume = (2 × original side length)^3 Since the original volume is 8 cubic meters, we can find the original side length by taking the cube root of 8: Original side length = ∛8 = 2 meters Now, we can find the new volume: New volume = (2 × 2)^3 = (4)^3 = 64 cubic meters So, the correct answer is: 64
Answer: 39
Explanation A composite number is a positive integer that can be formed by multiplying two smaller positive integers like 6 is a composite number because 3x2 = 6 Factorization: 3 × 13 = 39 composite numbers up to 50 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50

Answer: 512
Explanation Pattern 2,8,32,128,___,2048 As we see that each term multiplied by 4 is next term. Which is 2x4=8, 8x4=32 and so on.. So, the blank missing number will be 128x4=512, So the missing number will be 512.
Answer: 75 degree
Explanation Hour hand moves 225° (7.5 hours). Minute hand moves 180° (30 minutes). Angle between them : 45° (difference) + 30° (hour hand's extra move) = 75° . OR = 8h x 30 - 30 x 11/2 = 240 - 165 = 75°
Answer: 49
Explanation Given proportion: 2 : 7 :: 14 : x We can set up an equation based on the proportion: 2/7 = 14/x Cross-multiplying: 2x = 14 × 7 2x = 98 Dividing both sides by 2: x = 98/2 x = 49
