I think it is 64 cause i multiplied
Answer:
35
Step-by-step explanation:
40=1/2(115-x)
80=115-x
-35=-x
x=35
Answer:
x=7
Step-by-step explanation:
The two triangles are similar .
We can use the ratio's of the side to figure out x
2 3.5
-------- = --------------
4 x
Using cross products
2x = 4*3.5
2x=14
Divide each side by 2.
2x/2 = 14/2
x=7
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
