1. It's a proportion...50 over 12.5 = h over 50 then cross multiply and divide
2. Another proportion 7over x = 2 over 6 then cross multiply and divide
Scale Factor 1: 42
-----------------------------------------------------
Find actual length for 125 inches:
------------------------------------------------------
125 x 42 = 5250 inches
------------------------------------------------------
Find actual length for 3 inches:
------------------------------------------------------
3 x 42 = 126 inches

5250 inches by 126 inches
Answer:
4.02°
Step-by-step explanation:
The angle of descent can be obtained using trigonometry ;
Since we have a right angled triangle ;
Let's use the relation:
Sin θ = opposite / hypotenus
Hypotenus = 2.7 miles
1 mile = 5280 feets
2.7 miles = (2.7 * 5280) = 14256 feets
Sin θ = 1000 / 14256
Sin θ = 0.0701459
θ = sin^-1(0.0701459)
θ = 4.0223674
Simply using the given formula ,
I = P × R × t
I = 100 × 10/100 × 3
I = $30
