Answer:
2000 meters
Step-by-step explanation:
When the motorboat is moving downstream, its speed relative to the ground is 18 km/h, so its speed relative to the raft is 15 km/h.
When the motorboat is moving upstream, its speed relative to the ground is 12 km/h, so its speed relative to the raft is again 15 km/h.
Converted to m/min, the relative speed is:
15 km/h × (1000 m/km) × (1 h / 60 min) = 250 m/min
It takes the motorboat 16 minutes to travel to the front of the raft and back. Since the speed is the same in both directions, the motorboat takes 8 minutes to travel the length of the raft.
So the length of the raft is 250×8 = 2000 meters.
Answer:
∠E = 146°
Step-by-step explanation:
- an isosceles triangle has both two equal sides and two equal angles
- the sum of the interior angles of a triangle is 180°
- the measure of third angle = the sum of the interior angles - the sum of two angles
E = 180 - (71 + 71) = 146
∠E = 146°
Answer:
Step-by-step explanation:
radius r = diameter/2 = 2.5 yards
area = πr² = 6.25π square yards ≅ 19.625 square yards
Check the picture below.
so, as you can see, the UV segment is parallel to ZW, and therefore, they're the same slope, hmmm wait just a second, what is the slope of ZW anyway?

since now we know the ZW slope, we also know what is the slope for UV, thus,
