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.

The area of the triangle is always (1/2)bh with b being base and h being height. Any of the sides can be the base.
Answer:
C/d = 31.4/10
Step-by-step explanation:
We know the formula of the circumference, which ir:
C = pi*d
Where C is the circumference and d is the diameter of the circle. If we want to know the value of the pi number we just need to divide both sides of the equation above by d:
C/d = pi*d/d
C/d = pi
Thus, we can write pi as the ratio C:d or C/d, which means, how many times the diameter enters on the circumference. In our case is:
pi = 31.4/10 = 3.14
And 3.14 is how we usually use the pi number.
I would estimate 7 10/12 to 8 and i would estimate 2 11/12 to 3 so 8 plus 3 would equal 11 so that would be the estimate. the actual would be 10 8/11 so the estimate would be bigger.
