Answer:
a) 6080 ft
b) 29.952 mph = 30 mph to 2s.f
c) 15.6 knots
Step-by-step explanation:
Length of an arc is given as (θ/360) × (2πr)
For a nautical mile, θ = 1' = (1/60)° = 0.01667°
Length of a nautical mile = (0.01667/360) × (2π × 3960) = 1.152 miles
1 mile = 5280 ft
1.152 miles = 5280×1.152 = 6082.1 ft = 6080 ft to the nearest 10 feet.
b) 1 knot = 1 nautical mile/hour
1 nautical mile/hour = 1.152 miles/hour (from part (a))
1 knot = 1.152 miles/hour
26 knots = 26 × 1.152 miles/hour = 29.952 mph = 30 mph to 2 s.f
c) 1.152 mph = 1 knot
18 mph = (18×1/1.152) knots = 15.625 knots
Whats the question? Kinda blurry..
Answer:
C. 10x=16
Step-by-step explanation:
3(2x-1)+4x=13
Distribute the 3 by multiplying it by 2x and -1.
6x-3+4x=13
Add same properties. 6x and 4x 6x+4x=10x
10x-3=13
Add 3 to both side get rid of the negative 3 -3+3=0 13+3=16
10x=16
