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
The percentage increase of tvs sold ilfrom 50 and 60 is 20%
<h3>What is percentage increase?</h3>
percentage increase can be regarded as the
relative change and relative difference used in comparing two quantities.
The percentage increase can be calculated as;
[50/100] = [60/x]
if we cross products, we have
[50x]=[6000]
Then
x=120
Therefore, 60 is 120% of 50
Then the percentage increase of tvs sold ilfrom 50 and 60 is 20%
