Answer:
D
Step-by-step explanation:
4 people = 15 days
1 people = 15/4 = 3.75
so, 6 people = 3.75 × 6
= 22.5
The area of the sector is 5.9 m²
Step-by-step explanation:
The problem pertains to the area of an arc.
We know that area of the arc is given by= (central angle/360°)*π*r
²
Where r is the radius of the circle= diameter/2
Here diameter of the circle= 6 m
⇒Radius= 6/2= 3m
Substituting the values of the central angle as 75° (given), “r” as 3m, we get-
⇒Area of the sector= (75°/360°)*3.14*(3)
²
⇒Area of the sector=0.20834*3.14*9
⇒Area of the sector=5.9 m² (rounded off to the nearest tenth place after decimal)
Hence, area of the sector is 5.9 m²

Answer:
6.302×10^7 kg
Step-by-step explanation:
Since we want to find the difference in mass, we need to have the same exponent on both numbers. For that purpose, it is convenient to change the representation of the train's mass to 0.998×10^7 kg.
The carrier has more mass by the amount of ...
7.3×10^7 -0.998×10^7 = (7.300 -0.998)×10^7 = 6.302×10^7 . . . kg
