Answer:
186 cm
Step-by-step explanation:
Since the bicycle wheel is making a rotation and not a revolution, the bicycle wheel is at one point.
The length of the trace of water left on the floor is simply the circumference of the bicycle wheel
Circumference = 2πR
where R = radius of the bicycle wheel
and π = pie
Circumference = 2 × (22/7) × 30 = 188.57143 cm

Answer:
Step-by-step explanation:
<u>Given</u>
- Q = 7m + 3n,
- R = 11 - 2m,
- S = n + 5,
- T = -m - 3n + 8
<u>Simplify [Q - R] + [S - T]</u>
- (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
- 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
- m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
- 10m + 7n - 14
