Question

The center bead of a pearl necklace has a 16-millimeter diameter. Each successive bead in each direction is the diameter of the previous one. Find the diameter of the beads that are three away from the center bead.

Answer 1

To find the diameter of the beads three away from the center bead, halve the diameter of the center bead three times.

Step-by-step explanation:

To find the diameter of the beads that are three away from the center bead, we need to understand the pattern of the bead diameters. Each successive bead in each direction has the same diameter as the previous one. Starting with the center bead, the diameters decrease by half with each bead. So, the diameter of the beads that are three away from the center bead can be found by halving the diameter of the center bead three times.

Given that the center bead has a diameter of 16 millimeters, we can find the diameter of the beads three away from the center bead using the following steps:

1. Halve the diameter of the center bead: 16 mm ÷ 2 = 8 mm
2. Halve the diameter again: 8 mm ÷ 2 = 4 mm
3. Halve the diameter one more time: 4 mm ÷ 2 = 2 mm

Therefore, the diameter of the beads that are three away from the center bead is 2 millimeters.
