Arc length is 12436.8m
Step-by-step explanation:
arc length = 
* πD
where M is the angle measure of the arc
and D is the diameter
considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees
* π * 7917.5 = 12436.8m
Pretty sure it’s a circle , why would it be a rectangle and a right angle
Answer:1 1/20
Step-by-step explanation:
2 5/8 x 2/5
(8x2+5)/8 x 2/5
21/8 x 2/5
(21 x 2) ➗ (8 x 5)
42 ➗ 40
42/40=21/20=1 1/20
Answer:
the answer is x=-25/56
Step-by-step explanation:
2 4/5x=-1 1/4
14/5x=-5/4
x=-25/56
It travels a foot each day so it would take 20 days to fall back down to 19
