You make a necklace using blue, purple and green beads in a ratio of 1: 1: 2. you use a total of 168 beads. how many green beads are in the necklace?

84

Step-by-step explanation:

Given,

The ratio of blue, purple and green beads in the necklace = 1 : 1 : 2

Let blue beads = x, purple beads = x and green beads = 2x

Where,

x is any positive real number,

So, the total number of beads = x + x + 2x = 4x

According to the question,

4x = 168

x = 42,

Hence, the number of green beads in necklace = 2(42) = 84

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
