Answer:
There are <u>20 beads</u> on the necklace.
Step-by-step explanation:
Given:
A beaded necklace is 2.5 feet long. Each bead is .25 inches wide & each pair of beads is separated by 1.25 inches of chain.
Now, to find the number of beads on the necklace.
The length of necklace = 2.5 feet.
So, we convert feet into inches by using conversion factor:
<em>1 foot = 12 inches.</em>
<em>2.5 feet = 12 × 2.5 inches.</em>
<em>2.5 feet = 30 inches.</em>
<u>Thus, the length of necklace is 30 inches.</u>
Let the number of beads be
The width of each bead = 0.25 inches.
The each pair of beads is separated by 1.25 inches.
Now, we put an equation to get the number of beads:
<em>Dividing both sides by 1.50 we get:</em>
<u><em>The number of beads = 20.</em></u>
Therefore, there are 20 beads on the necklace.
The parts of a circle are the r<em>adius, diameter, circumference, arc, chord, secant, tangent, sector and segment.</em>
Radius:
The distance from the center to any point on the circle.
Diameter:
The distance across the circle through the center point.
Circumference:
The distance around a circle.
Arc:
arcs in the same circle that have exactly one point in common. measure of arc divided by 360 multiplied by the circumference. the length of an arc. semicircle. an arc that is half of a circle; always measures 180 degrees.
Chord:
a line segment that connects two points of a circle.
Secant:
A secant is a line that intersects a circle in two points.
Tangent:
A tangent is a line that intersects the circle in exactly one point.
Sector:
region bounded by an arc of a circle and the two radii to the arc's endpoints. - A sector is like a "pizza slice" of the circle. It consists of a region bounded by two radii and an arc lying between the radii.
Segment:
A segment or length of a segment with one endpoint at the center of the circle.
