we are given
speed is 850mi/h
we know that
1 mile =1609.34 metre
1 hour = 3600 second
now, we can replace 1mi and 1hour

now, we can solve it
379.98306
...........Answer
1 hour =60 minutes
So the answer is 0.1 mile/ minute
The length of one side of the octagon is given by:

Then, the apothem can be determined using the Pythagorean theorem in the following way:

Clearing to have:

Then, the area is given by:

Where,
L: length of the octagon sides
a: apotema
Substituting values:
Answer:
the approximate length of the apothem is:
a = 10.91 feet
The approximate area of the floor of the gazebo is:
A = 392.76 feet ^ 2
Answer:44
Step-by-step explanation:
0.2x+(-0.9)+1.7==9.6
0.2x+0.8=9.6
Subtract 0.8 from both sides
0.2x+0.8-0.8=9.6-0.8
0.2x=8.8
Divide both sides by 0.2
0.2x ➗ 0.2=8.8 ➗ 0.2
x=44
