The first one is negative 1
D. 24.84KM/H
Because 6.9m/s x 1KM/1000m x 3600s/1h = 24.84KM/H
Answer:
48
Step-by-step explanation:
Answer:
Population after 4 years = 49 (nearest unit)
Population after 5 years = 47 (nearest unit)
Step-by-step explanation:
Yearly decrease = 4.6%
Decrease factor (what's left) = (100-4.6)% = 0.954
Current population, P = 60
population after n years = P(0.954)^n (to the nearest unit)
Population after 4 years = 60(0.954)^4 = 49.7 = 49 (nearest unit)
Population after 5 years = 60(0.954)^5 = 47.4 = 47 (nearest unit)
Option D is the correct answer
A triangle’s angles must add up to 180 to be a proper triangle. Option A, B, and C added up all equal 180, whereas option D only equals 150.
