Answer:
f = 5/3
Step-by-step explanation:
3/4 f = 5/4
Multiply each side by 4/3 to isolate f
4/3 *3/4 f = 5/4 *4/3
f = 5/3
$12 + $12 + $13 + $13 + $13 + $17 + $17 + $17 + $17 + $17 = 148
148 ÷ 10 = 14.8
$14.80 is the median amount the ten friends had to pay.
V = rw
where; v = velocity , r = radius , w = angular speed
you're given the diameter = 0.5 miles so the radius = 0.25 miles
180 = (0.25)w
180/0.25 = w
720 radians per hour = w
2pi radians in 1 revolution
720 rad/hr * 1 rev / 2pi rad = 720/2pi rev/hr
= 114.6 rev/hr
Answer:
Divide the central angle in radians by 2 and perform the sine function on it. Divide the chord length by double the result of step 1. This calculation gives you the radius. Multiply the radius by the central angle to get the arc length.
