Triangle ABC is similar to triangle ADE.
The scale factor from ADE to ABC is 2. We know this because two of the sides on the triangle are equally divided into 2.
29(2) = 58
BC = 58
3/6= 1/2 because 3 is the half of 6 and 1 is the half of 2
5/20= 1/4 because 1 x 5= 5 and 4 x 5= 20
9/27= 1/3 because 1 x 9 =9 and 3 x 9=27
1/2 is the simplest form already
12/36= 1/3 because 1 x 12= 12 and 3 x 12= 36
Answer:
Feet and yards; the 1 whole strip could represent 1 yd. and the 
strip could represent feet.
P(allergic) = 0.15
P(both are allergic to pollen) = (0.15)² = 0.0225 (you can use the binomial probability also)
Q(NOT allergic to pollen) = 1 - 0.0225 = 0.9775
Binomial probability
Probability of NEITHER is allergic
ⁿCₓ(p)ˣ(q)ⁿ⁻ˣ
²C₀(0.15)⁰(0.9775)² = 0.9555
P(at LEAST ONE is allergic) = 1- 0.9555 = 0.0444
