Well the thing is you didn't tell us which number but if it is 12 then i strongly believe that the answer is 3/9
He would need a total of 46 yard of lights
Answer:
The answer to the question is;
The distance the tip of the minute and travels as time progresses from 12:00 to 12:25 is 18.33 in.
Step-by-step explanation:
To solve the question, we note that
Number of minutes in one complete revolution of the clock = 60
Position travel of the minute hand = 12:00 to 12:25 = 25 minutes
Fraction of complete revolution traveled by minute hand = 25/60
Distance of one complete revolution = Circumference of circle = 2·π·r
Length of minute hand = 7 inches = r
Distance of one complete revolution = 2 × π × 7 = 43.98 in
Distance traveled by minute hand = 25/60×43.98 in = 18.33 in.
We have two relations between length and width. One is given in the problem statement. The other is given by the formula for perimeter. We can solve the two equations in two unknowns using substitution.
Let w and l represent the width and length of the sign in feet, respectively.
... l = 2w -12 . . . . . the length is 12 ft less than twice the width
... p = 2(l +w) = 114 . . . . the perimeter is 114 ft
Using the first equation for l, we can substitute for l in the second equation.
... 114 = 2((2w -12) +w)
... 114 = 6w -24 . . . . . . . . simpify
... 138 = 6w . . . . . . . . . . . add 24
... 23 = w . . . . . . . . . . . . . divide by 6
... l = 2w -12 = 2·23 -12 = 34 . . . . use the equation for l to find l
The length and width of the sign are 34 ft and 23 ft, respectively.
