Answer:
- arc second of longitude: 75.322 ft
- arc second of latitude: 101.355 ft
Explanation:
The circumference of the earth at the given radius is ...
2π(20,906,000 ft) ≈ 131,356,272 ft
If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...
(360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle
Then one arc-second is
(131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second
__
Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.
_____
<em>Comment on these distance measures</em>
We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
Answer:
min = 64.2m ; max = 86.2m
Step-by-step explanation:
Answer:
The sum of the numbers is <em>132</em>
Step-by-step explanation:
First find the smallest number
- 3/8=x/96
- 2(96)=8x
- 288=8x
- x=36
Thus, you found the smallest number
then there sum given as 96+36=132
Answer:
15 students are girls
Step-by-step explanation:
7+5=12
36÷12=3
3x5=15
A line parallel to another line will have the same slope.
Therefore the answer is 5.
