I'd say Yana has 6...
30\ 6 is 5
the ratio range is a group inside 5..
so Dina has 30 swim suits...which is 5 times 6 of yana.
so since Dina has 24 "more" than yana... Dina is 4 : Yana is 1....4:1
First you distribute...
8 + 4x - 20
Then you simplify...
4x - 12
Done
First break= 1/2
second break = 1/2 of half= 1/4
third break = half of 1/4 = 1/8
forth break = 1/2 of 1/8 = 1/16
fifth break = 1/2 of 1/16 =1/32
fraction painted = 1 -1/32 =31/32
portion painted = 150*31/32 = 145.3125 ft^2
Tan 2° = x / 1 mile, where x is the vertical change
0.03492 = x / 1 mile
x = 1 mile · 0.03429 = 0.03492 miles
1 mile = 5,280 feet
0.03492 · 5,280 = 184.38 ft
Answer: The vertical change is 184.38 feet
