Answer:
3.The angle is 24°
4.120°
Step-by-step explanation:
There are 360° in a complete revolution thus for 15 equally space spokes, the angle between every spoke is given by 360° ÷ 15 =24°
In a clock, a complete revolution yields 360°. For a 20 minutes turn, the minute hand will cover (360° ÷ 12) × 4 =120°
30t=50(t-1)
30t=50t-50
30t-50t=-50
-20t=-50
t=-50/-20
t=2.5 hours after the freight train leaves the station they will meet
Uh they must be good at math and that’s impressive? lol
I think its dilation and rotation. Hope it helps.
