Answer:
About 90.73 meters/min.
Step-by-step explanation:
Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.
First, we will convert feet to meters, using that 1 ft = .4048 m.
32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.
Second, we convert seconds to minutes, using that 60 sec = 1 min.
9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.
C) 18 is not a prime number
1, 2, 3, 6 ,9, 18
Are all factors of 18, making it not prime
Answer:
A = -7.5 B = -17.5
Step-by-step explanation:
A + B = -25
A = B + 10
<u>Plug the second equation into the first equation:</u>
B + 10 + B = -25
2B = -35
B = -17.5
Plug that value into the first equation:
A - 17.5 = -25
A = -7.5
As we can see from the table there is a pattern to the whole data in the table. A closer look reveals that when we multiply the number of students, n by the cost per student, c we get a constant number, 72. Let us see what we mean here:
![3\times24=72](https://tex.z-dn.net/?f=3%5Ctimes24%3D72)
![6\times 12=72](https://tex.z-dn.net/?f=6%5Ctimes%2012%3D72)
![9\times 8=72](https://tex.z-dn.net/?f=9%5Ctimes%208%3D72)
![16\times 4.5=72](https://tex.z-dn.net/?f=16%5Ctimes%204.5%3D72)
Thus, the function which models the data is the
.
Now, let us move on to the next part of the question:
If 12 students go on the trip then the cost per student as per this model will be:
dollars=$6
Therefore, out of the given options, the option the correct option is number B.
