Answer:
8 1/3+9 4/5+ 11 5/6+12+14 7/8=<u>58 61/120</u>
Step-by-step explanation:
First, you would add all of the whole numbers: 8+9+11+1+2+14=54
Second, you would add all of the fractions 1/3+4/5+5/6+7/8=4 61/120
Lastly, 54+4 61/120=<u>58 61/120</u>
Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.
Step-by-step explanation:
The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that
P is directly proportional to S
Introducing a constant of proportionality, k, it becomes
P = kS
A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that
750 = k × 37
k = 750/37 = 20.27
The expression becomes
P = 20.27S
Therefore, the output for a wind speed of 40 miles per hour would be
P = 20.27 × 40
P = 810.8
So some quick tips for inequalities:
**What you do to one side you HAVE TO do it to the other 2**
**If you ever divide a negative number past the inequality signs, the signs FLIP!!**
(e.g. 2>-5x>25)
-2/5 <x < -5
I hope that this has helped!
