Answer: a = 1/6
Explanation: Convert the mixed number into an improper fractions. Which is 21/4.
Then you can do the butterfly method.
Answer:
Step-by-step explanation:
you multiply it with 100
0.23 x 100 = 23%
Answer: 
Step-by-step explanation:
We are told the wind turbine makes 76 revolutions in 1 minute. This means the angular speed 
of the object in revolutions per minute (rpm) is:
(1)
However, we have to convert this to 
, since this is the unit used in the International Systme of Units for angular speed.
So, we can do this knowing that:
(2)
Where:
is the value of one revolution
is the period of rotation
With this information in mind, let's make the conversion:
(3)
(4) This is the wind turbine angular speed
y=0x-3 because the slope is undefined, so it is 0 and the y intercept is -3 because it goes across the y axis.
