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
2(8x + 2) - 5 + 5x
2(8x) + 2(2) - 5 + 5x
16x + 4 - 5 + 5x
16x - 1 + 5x
16x + 5x - 1
21x - 1
Answer:
6. B
7. D
Step-by-step explanation:
For 6 found that the 56 pieces in the first bag was about 18% of that bag. So then I found that 18% of 450 is ruffly 84, so B
For 7 I multiplied 5x5 is 25 so then 50x5 is 250, which is D
" the sum " means add
16 + x = 20 <= ur equation
x = 20 - 16
x = 4 <== the number
