Find radians per second then multiply by 60
2.4 rev/ 3 s x 2pi R/rev = 5.0265 R/s
now multiply by 60 to get R/min
Me too! I don't tolerate panhandlers...... it only encourages them
n = nickels value = 5n
q = quarters = 27-n value = 25 (27-n) summed = 395
5n + 25(27-n) = 395 solve for n the number of nickels =.........
Depends on how much you gave away !
If you gave what each asked
12.30 - 2.00 - 2.00 - 5.00 = $ 3.30
rectangle = 8x 15 m^2
semi circle = 1/2 pi r^2 ( r = radius = 4 m )
Add them together = .....
.85x = 170
x = 170/.85 = .........
30 miles round trip 30 m / 2 m/hr = 15 hr
They both encompass the sam arc ABC measures twice ADC
20 sides so 20 partial rotations before you're back to where you started (360o)
