A plane covers 2,160 miles in 5.5 hours. what is the average speed of the plane to the nearest tenth?
2 answers:
Answer:
Hence, the average speed of the plane is:
392.7 miles/hour.
Step-by-step explanation:
The distance covered by a plane is: 2160 miles.
Also the time taken by the plane to cover this distance is: 5.5 hours.
Now, the average speed of the plane is the ratio of the total distance covered to the total time taken.
i..e
Speed=Distance/Time.
Hence,
Hence, average speed is:
392.7 miles/hour

You transformed the function as follows:
All trasformations of the fashion translate the function horizontally, k units right if k is positive, k units left if k is negative.
In your case, k=6, so you translated the original function y=|x| 6 units to the right.
Answer:
x = 6
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = Al ( A is the area of the triangular end and l is its length )
A = bh = 0.5 × 9 × 4 = 18 cm² , then
V = 18 × 12 = 216 cm³
The volume of a cube is
V = s³ ( s is the side length ) , so
s³ = x³ = 216 ( take the cube root of both sides )
x = = 6
