Answer:
Step-by-step explanation:
30*15%=9/2=4.5
so 4.5 would be travelling outside of New York
this gives 30-4.5=25.5 that are not traveling
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
Answer:
![661.4\ rpm](https://tex.z-dn.net/?f=661.4%5C%20rpm)
Step-by-step explanation:
we know that
1 mile=63,360 inches
step 1
Find the circumference of the wheels
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
we have
-----> the radius is half the diameter
substitute
![C=2\pi(15)](https://tex.z-dn.net/?f=C%3D2%5Cpi%2815%29)
![C=30\pi\ in](https://tex.z-dn.net/?f=C%3D30%5Cpi%5C%20in)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
![C=30(3.14)=94.2\ in](https://tex.z-dn.net/?f=C%3D30%283.14%29%3D94.2%5C%20in)
Remember that
The circumference of the wheels represent one revolution
Convert 59 miles per hour to inches per minute
![59\ mi/h=59*63,360/60=62,304\ in/min](https://tex.z-dn.net/?f=59%5C%20mi%2Fh%3D59%2A63%2C360%2F60%3D62%2C304%5C%20in%2Fmin)
using proportion find the number of revolutions
![\frac{1}{94.2}\frac{rev}{in}=\frac{x}{62,304}\frac{rev}{in}\\ \\x=62,304/94.2\\ \\x=661.4\ rev](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B94.2%7D%5Cfrac%7Brev%7D%7Bin%7D%3D%5Cfrac%7Bx%7D%7B62%2C304%7D%5Cfrac%7Brev%7D%7Bin%7D%5C%5C%20%5C%5Cx%3D62%2C304%2F94.2%5C%5C%20%5C%5Cx%3D661.4%5C%20rev)
therefore
substitute
![62,304\ in/min=661.4\ rev/min=661.4\ rpm](https://tex.z-dn.net/?f=62%2C304%5C%20in%2Fmin%3D661.4%5C%20rev%2Fmin%3D661.4%5C%20rpm)

Answer:
Factoring is taking the greatest factor of an equation/expression and putting it behind parenthesis.
For example:
2+4: Factor it
2 is the greatest factor of the two
SO
2(1+2)
Ill give you a try it and you can factor it. I might check it later on.
42+ 36
If you are looking for something harder:
4x^4+ 6x^6
