He pays $780 for the television set.
1200*.35=420
1200-420=780
You would subtract 5x from y so y=5x-10
The value of the digit 4 is worth 4,000 in the number 84,230.
<span>First find the central angle A in degree.
Perimeter circle 2Pi*R --> 360 deg
Arc A = 14.13 --> x deg
(360*14.13)/2Pi*R = 5086.8/37.68 = 135 deg
The pendulum rotates 135 deg in 3 sec. Then, the angular velocity is : 135/3 = 45 deg/sec.
Hope this helps!
