<h2>I HOPE IT IS HELPFUL</h2>
Answer:
Step-by-step explanation:
b and c are the speeds of the boat and current, respectively.
Traveling upstream, the boat moves b-c km per hour.
Traveling downstream, the boat moves b+c km per hour.
b-c = (60 km)/(½ h) = (120 km)/h
b+c = (60 km)/(⅓ h) = (180 km)/h
Adding the equations together,
2b = (300 km)/h
b = (150 km)/h
c = (30 km)/h
Answer:
Yes
Step-by-step explanation:
Theorem 8.3: If two angles are complementary to the same angle, then these two angles are congruent.
Answer:
- Perimeter: 7.8
- Area: 3.1
Step-by-step explanation:
- Perimeter = all sides added up together
- 2.8 + 2.8 + 1.1 + 1.1 = 7.8
- Area = L × W
- 2.8 × 1.1 = 3.08
- Round 3.08 to the nearest tenth: 3.08 → 3.1
I hope this helps!
