1.75...?
Step-by-step explanation:
Uhh... Well if you're that desperate I'll try it.
If the actual football diameter is 21
Plug it into 1 : 12
x : 21
x / 21 = 1 / 12
12x = 21
x = 7 / 4

Answer:
$ 1,200 per square foot
Step-by-step explanation:
If you divide 540,000 by 450 you will get 1,200.
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
<span>ω = 5 revolutions per minute. 1 minute = (1/60) hour. </span>
<span>= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14 </span>
= 600*3.14 = 1884 radians / hour
<span>but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile </span>
Linear velocity, v = ωr
<span> v = 1884 radians / hour * (10/5280) mile </span>
v ≈ 3.568 miles / hour<span />
