Step-by-step explanation: 7 + -6 = 1
:\
N=5 or n=9 can be either one
Hope this helped
5π rad/sec= 60 x 2.5 = 150 rpm. The bicycle travels 27π inches per revolution
<span>150 rpm = 150 x 27π in/min = (150 x 27π x 60)/(5280 x 12) = 12.05 mph </span>
Answer:
inches.
Step-by-step explanation:
The length of the outer edge of the wheel between two consecutive spokes is given by;
![l=d\sin(\frac{\theta}{2} )](https://tex.z-dn.net/?f=l%3Dd%5Csin%28%5Cfrac%7B%5Ctheta%7D%7B2%7D%20%29)
where d=18 inches.
and
is the central angle.
We substitute the values to obtain;
![l=18\sin(\frac{36\degree}{2})](https://tex.z-dn.net/?f=l%3D18%5Csin%28%5Cfrac%7B36%5Cdegree%7D%7B2%7D%29)
![l=18\sin(18\degree)](https://tex.z-dn.net/?f=l%3D18%5Csin%2818%5Cdegree%29)
![l=5.562305899](https://tex.z-dn.net/?f=l%3D5.562305899)
inches to the nearest tenth.
Answer:
x=10 degrees
Step-by-step explanation:
2x+8+62=90
2x+70=90
2x=20
x=10
