Answer: It needs 2.4 hours to complete the trip.
Step-by-step explanation:
Since we have given that
Length of Oregon trail = 2.197 miles
Speed at which it travel = 20 miles per day
we need to find the time taken by it ,
As we know that
So,
it will be changed into hours
so, it needs 2.4 hours to complete the trip.

Answer:
about 1.5 pounds
Step-by-step explanation:
The moon's gravity is about 1/6 that of Earth, so a 9-lb cat would weigh about 9/6 = 1.5 pounds on the moon.
Answer: area of shaded region is 141.3 cm²
Step-by-step explanation:
We would assume that the shade region is the area between both circles. The area of the shaded region is the area of the outer circle - the area of the inner circle.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
Radius = 6 cm
Area = 3.14 × 6² = 113.04 cm²
Considering the outer circle,
Radius = 9 cm
Area = 3.14 × 9² = 254.34 cm²
Area of the shaded region is
254.34 - 113.04 = 141.3 cm²
