A wet bicycle tire leaves a trace of water on the floor. The tire has a radius of 30 \text{ cm}30 cm30, start text, space, c, m, end text, and the bicycle wheel makes 333 full rotations before stopping. How long is the trace of water left on the floor? Round your answer to the nearest

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

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
