Answer:
4
Step-by-step explanation:
Initial velocity = 0 m/s
Acceleration = 9.8 m/s²
Time = 3.1 s
s = ut + 1/2 at²
s = 1/2 x 9.8 x 3.1²
s = 47.1 m
The building is 47.1 meters tall
Add all the fractions together:
to do this find the lcd:
which is 60
1/10 = 6/60
1/4= 15/60
1/5= 12/60
2/15= 8/60
add them together
(6+15+12+8)/60
41/60 or C is the answer
Answer:
1) 40°
2) 140°
3) 140°
5)40°
6)140°
7)140°
8)40°
Step-by-step explanation:
1 = 40 ° <em> [Vertically Opposite angles are equal]</em>
8 = 40 ° <em>[Corresponding Angles are equal]</em>
5 = 8 = 40° <em> [Corresponding Angles are equal]</em>
7 = 180° - 40° = 140° <em>[Supplementary angles sum 180°]</em>
6 = 140° <em> [Vertically Opposite angles are equal]</em>
2 = 140° <em>[Corresponding Angles are equal]</em>
3 = 140 ° <em> [Vertically Opposite angles are equal]</em>
