Problem 1
Answers: Choice A, choice D
The formula you use is
a & c/d = (a*d+c)/d
To convert from mixed number form to improper fraction form.
So,
6 & 2/3 = (6*3+2)/3 = (18+2)/3 = 20/3
And also,
8 & 1/5 = (8*5+1)/5 = (40+1)/5 = 41/5

Problem 2
Answer: Reflection
Think of how mirrors cause a reflection and this should help you remember the term better. If we reflect point A over some line L, to get point A', then the distance from A to L is the same from A' to L also.

Answer:
angle of depression = 2.1⁰
Step-by-step explanation:
1 mile = 5280 ft
Hence angle of depression = 90 - ∅
Where ∅ is angle of depression
Tan ∅ = (5 x 5280)/ 950
∅ = Tan₋¹ (27.789474) = 87.9⁰
Hence angle of depression = 90 - 87.9 = 2.1⁰
P=2₶R
P=2*3.14*19cm = 119.38cm
