So, 4 x 3 is 12, so 4 blades cost 79.74 x 3 (because every turbine has 3 blades each) is 318.96
Trigonometry:
Sine 75 = x/ 9
x = 9 Sine 75
x = 8.7
Answer:
B) measures of variability
Hope this helped :)
There will be 9 inches on the map for we just take 27:3. Hope you get it.
No.
Since w = 8, you must replace the variable with the number associated to it.
So, it would be 5 + 8 = 58
5 + 8 is not equal to 58, it is equal to 13.
If you wanted to find out what w was, simply subtract 5 on both sides.
w = 58 - 5
