Answer:
<u>18</u> passengers the roller coaster can take around the track per minute.
Step-by-step explanation:
Given:
A roller coaster can take 162 passengers around the track in nine minutes. The roller coaster operates at a constant rate.
Now, to find the number of passengers roller coaster take around the track per minute.
As given in 9 minutes the roller coaster track 162 passengers.
So, we solve by using unitary method:
In 9 minutes the roller coaster take passengers = 162.
Thus, in 1 minute it can take
Therefore, 18 passengers the roller coaster can take around the track per minute.

Answer:
The slope of the line must be 3
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
step 1
we know that
The volume of a rectangular prism is equal to
----> equation A
where
B is the area of the base of the prism
h is the height of the rectangular prism
step 2
The volume of a square pyramid is equal to
-----> equation B
where
B is the area of the square base of pyramid
h is the height of the pyramid
step 3
substitute equation A in equation B
Find the relationship between the volume of a rectangular prism and the volume of a square pyramid
therefore
The slope of the line must be 3
let's check it
To solve for the slope of the line, you must choose two coordinates first and use the formula
Choosing the points (2,6) and (3,9)
substitute
----> is correct
