The central angle with vertex at the center of the Earth is : α = 12` = 1/5° = 0.2°.
The distance between two islands:
L = R π α / 180°
Earth radius = 6,317 km = 3,959 miles
L = 3,959 · 3.14 · 0.2° / 180°
L = 13.82 miles
Answer: Two islands are 13.82 statute miles apart.

Im willing to give 20 points maybe even more
Thepotemich [5.8K]

Answer:

Equations are

20c + 10m = 495..............(1)

8c + 1m = 178.5.................(2)

Now ,  equation (2) * 10 = 80c + 10m = 1785...........(3)

So, Eq. (3) -  Eq(1) =

80c + 10m - 20c - 10m = 1785 - 495

60c = 1290

c= 21.5

********************************************************

Now place the value of c in Eq (2)

So , m =6.5

Slope = 4/3, (-2, 11)
Lady_Fox [76]

Answer:

y = \frac{4}{3} x + \frac{41}{3}

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = \frac{4}{3}, hence

y = \frac{4}{3} x + c ← is the partial equation

to find c substitute (- 2, 11) into the partial equation

11 = - \frac{8}{3} + c ⇒ c = \frac{41}{3}

y = \frac{4}{3} x + \frac{41}{3} ← equation of line
