Answer: 2041 meters
A bicycle wheel is a circular object.
The circumference of a circle is 2π(radius)
Here given:
- radius = diameter/2 = 65/2 = 32.5 cm
Hence find the length for each revolution:
- 2π(32.5) = 204.1 cm per revolution
Then for 1000 revolutions:
- 204.1 × 1000 = 204100 cm ≈ 2041 meter
Answer:
2/3 + 1/5 = 13/15
Step-by-step explanation:
Answer: (E) Not necessarily, because this wasn't an experiment
Step-by-step explanation:
As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.
An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.
The variable "y" equals the square root of two and the negative square root of two.
The problem may be solved using the quadratic formula.
