Answer:
D
Step-by-step explanation:
A table shows a proportional relationship if all of the y/x ratios are the same.
A: 4/3 ≠ 10/6 . . . . not proportional
B: 6/12 ≠ 12/14 . . . . not proportional
C: 2/4 ≠ 20/20 . . . . not proportional
D: 1/5 = 2/10 = ... = 5/25 . . . . proportional relationship
The area of the square is 9, the area of all the semi circles added together is 15.7, when you add them together you get 24.7
I'm having the same troubles with this type of geometry sort of.
Well, this depends on the length of your outstretched arm from the joint of your shoulder to the joint of your thumb finger. Mine is 21 inches long. My thumb is 2.5 inches long. The angular diameter can be determined using the trigonometric functions. We can use the tangent function
tan θ = opposite side/adjacent side = thumb's length/shoulder-to-finger length
tan θ = 2.5 in/21 in
θ = 6.79°
