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
Hi there!
In order to find x, we'll need to create an expression. We know that angle x would be 180 - angle ABC - y. Since we know that angle ABC is equal to 30, we can substitute that in. This gives us 180 - 30 - y. Lastly, we can simplify to get our expression. The expression is 150 - y. The answer is the first option.
Hope this helps!! :)

Answer:
$99
Step-by-step explanation:
100 - (100 x .10) = 90
90 + (90 x .10) = 99
ok but I don't know what it is
