Answer:
The linear speed of the windmill is 32.682 ft/s.
Step-by-step explanation:
Given;
radius of the windmill, r = 26 ft
number of revolutions per minute, θ = 12 rpm
The angular speed of the windmill is given as;
The linear speed of the windmill is given as;
v = ωr
v = 1.257 rad/s x 26 ft
v = 32.682 ft/s
Therefore, the linear speed of the windmill is 32.682 ft/s.

Step-by-step explanation:
if you put twice as many pipes it should cut time down by half.
Answer:
x=180-(67+52)
Step-by-step explanation:
a linear pair is 180
we are already have two angles add them together
subtract that from 180 and you will get the last angle
Answer:
m=45 degrees
n=15 degrees
Step-by-step explanation:
m=45 degrees because other 2 angles in it's triangle =90+45=135 degrees
180 degrees in any triangle so m=180-135=45 degrees.
m+n=60 degrees so n=60-45=15 degrees
Answer:
$80
Step-by-step explanation:
x-55 =25
x=80
