Answer:

  a)  3.491 in/s

  b)  3.333 RPM

  c)  0.349 rad/s

Step-by-step explanation:

We know the arc length for a given radius and angle is ...

  s = rθ

so the linear speed along the arc is ...

  s' = rθ' = (10 in)(20π/180 rad/s) = 10π/9 in/s ≈ 3.491 in/s

__

The rotation rate of 20°/s is an angular velocity of ...

  (20°/s)(60s/min)(1 rev/360°) = 3.333 RPM

__

In the first part, we found the angular speed to be π/9 radians/sec. That's about ...

  π/9 rad/s ≈ 0.349 rad/s

By what number would you multiply to solve 4/5 t = 36
mihalych1998 [28]

Answer:

45

Step-by-step explanation:

4/5 t = 36

Divide both sides by 4/5

4/5 / 4/5 t = 36/4/5

4/5 cancels 4/5

Also flip the divisor 4/5

t = 36x5 / 4

= 180/4

= 45

Find the solution of this system of equations?<br><br> -8x-6y=60<br><br> 5x+6y=-69
zvonat [6]
First subtract the x variable on both sides so on the first equation youll have -6y=8x+60 then divide 6 on all variables which means youll have y=8/6x+10 and in the second equation you do the same thing and youll have y=-5/6x-11.5
