Answer:
2.5 cm/year
Step-by-step explanation:
Just divide the total distance, 250 cm, by the years, 100, 250/100 = 2.5, the rate of the contintents drifting away is 2.5 cm per year, 2.5 cm/year
So,
The diameter is 8.6ft. We need to convert to radius.
2 radius = 1 diameter
8.6/2 = 4.3 ft.
3.14(18.49)
58.0586ft.²
Divide by 2 (semi-circle)
29.0293ft.²
Answer:
Step-by-step explanation:
Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'
4. Question four is then lines b and a which is option B
Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'
5. Question 5 is therefore 'a' and 'c' which is option D
