Answer:
How do you write a number to the power of something ?
( ex : 125 to the power of 5 )
125⁵
thats it easy as much
The distance from the lighthouse to the boat will be given by:
tan θ=opposite/adjacent
θ=angle of depression=23
opposite= height of the lighthouse
adjacent=distance from the boat to the bottom of the light house
hence
tan 23=210/a
thus solving for a we obtain:
a=210/tan23
hence
a=494.73 ft
Answer:
Let x = the hours needed for Wanda to catch up to Hector.
Hector has already completed 18 miles. Hector travels at 12 miles per hour.
After x more hours, Hector will travel
18 + 12x miles
Wanda travels at 16 miles per hour. In x hours, she travels
16x miles
If Wanda catches up to Hector, then
16x = 18 + 12x
4x = 18
x = 4.5 hours
Answer: 4 hours, 30 minutes (or 4.5 hours)
Step-by-step explanation:
Divide 315,530,612 by 3,539,225 to get 89 people per square mile (rounded)
