Answer:
n = 1
Step-by-step explanation:
Represent the number with n.
Then: reciprocal of this numer is 1/n.
1/2 added to this reciprocal comes to 1/n + 1/2, and this is equal to
2(1/n) - 1.
We must simplify this equation and solve for n:
Use the LCD 2n:
2 + n = 4 - 1, or 2 + n = 3, or n = 1.
Answer:
274.23 feet
Step-by-step explanation:
From the question,
The measure of the arc between any two blades (s) = 2πrΦ/360
s = 2πrΦ/360................... Equation 1
Where Ф = angle formed betwen two blades, r = length of each blade.
Given: Ф = 360/3 (the three blades are equally spaced) = 120°, r = 131 feet.
Constant: π = 3.14
Substitute these values into equation 1
s = (2×3.14×131×120)/360
s = 274.23 feet.
Hence, the measure of the arc between any two blades is given = 274.23 feet
24=3+x i believe this correct since this is all the info you gave.
