Substitute 4 for y
Take square roots
There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
Answer:
8
Step-by-step explanation:
The amount of blocks that make up each layer would be best represented as the Length, Width and height
A number multiplied by itself 3 times = 512
8 x 8 x 8 = 512
64 x 8 = 512
512 = 512
Therefore, 8 blocks make up each layer
