1. If a bicycle wheel has a diameter of 15 in. How far will the wheel rotate in 10 rotations?​
WARRIOR [948]

Answer:

150 pi inches or 471.239 inches traveled

Step-by-step explanation:

First, close your eyes, and think about the distance a bike travels after one rotation of the wheel.

You will come to the realization that a full rotation of the wheel makes you travel the circumference of the wheel

The formula for circumference is 2(pi)(r) or (pi)(diameter)

We are given diameter, so let's find distance traveled for one rotation

pi(15 inches) = 15pi inches per rotation.

There are 10 rotations, so:

(15pi inches/rotation)(10 rotations) = 150pi inches travelled

150 x pi = 471.239 inches traveled

Rewrite the equation 2x+6x^(2)-1=3x^(2) in standard form and identify a, b, and c.
Fed [463]
Hi there!

2x + 6 {x}^{2}  - 1 = 3 {x}^{2}
First subtract 3x^2 from both sides.

2x + 3 {x}^{2}  - 1 = 0
Now rearrange the equation.

3 {x}^{2}  + 2x - 1 = 0
Finally we can see our answer.

a = 3
b = 2
c =  - 1
