Answer:
a) 2.5 km
b) 1836 m ≈ 1.8 km (rounded)
Step-by-step explanation:
a) just add the two distances of the vertical and horizontal road. 900m + 1600m = 2500m = 2.5 km
b) Apply Pythagoras (a²+b²=c², where a and b are the vertical and horizontal roads, and c is the diagonal road).
c = √(1600²+900²) ≈ 1836m (rounded)

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
21 ≤ - 3(x - 4) < 30
Divide all intervals by - 3, reversing the inequality symbols as a result of dividing by a negative quantity.
- 7 ≥ x - 4 > - 10 ( add 4 to each interval )
- 3 ≥ x > - 6, that is
- 6 < x ≤ - 3 → D
