Answer:
Step-by-step explanation:
Y= {2,4,6,8,10,12,14,16,18,20}<br>
X={4,8,12,16,20,24,28,32,36,40}<br>
Find the difference Y-X

Answer:
difference between Y-X = 2
Step-by-step explanation:
you can subtract 2-4 in Y and also in X 4-8
as the difference between 2 (2-4, 4-8) number would be 2. therefore difference is 2

Answer:
Ф=144
Ф =s/r ( Ф is the central angle,s is the arc length, r is the radius)
find r:
radius =circumference/2π=1/2π=0.16
Ф=(2/5) /(1/2π)=4π/5=144 degree (π=180)
Ф in degrees: 144 degrees
Multiply both sides by 20
2.82 × 10^5 = (7.5×10^-1) × Length between the earth and the moon
Length between the earth and the moon = (2.82×10^5)÷(7.5×10^-1) = 376000 = 3.76×10^5
i think this is correct hope it helps.
