Explanation: 6-3/0.4-0.2=3 over 0.2 which is equivalent to 15
Answer: 4*p=8
Step-by-step explanation:
<em>You can use inverse operation to answer this equation.</em>
- <em>write out you problem: 4 x p =8</em>
- <em>The inverse of multiplication is division</em>
- <em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
- <em>Do 8/4 which gives you 2</em>
- <em>under the equation write p = 2</em>
- <em>And be sure to line the p up with the p, the equal sign with the equal sign, and the 2 stays where it is ( which should be already lined up with the 8)</em>

Answer:
Option 3 ⇒ 210.08 rpm
Step-by-step explanation:
The relation between the angular velocity ω and the linear velocity v is v=ωr
Where r is the radius of the tire.
Given that a diameter of 24 inches. If he rides at 15 miles per hour.
∴ r = diameter/2 = 24/2 = 12 in.
And v = 15 miles/hour
Converting the speed to inches per minutes where mile = 63,360 inches and hour = 60 minuted
∴ v = 15 * 63,360/60 = 15,840 inches/minute
∴ ω = v/r = 15,840/12 = 1,320 rad/minute
Converting ω from rad per minutes to revolutions per minute
Where 1 revolution = 2π
∴ ω = 1,320 / (2π) = 210.08 rpm
He has 32 inch of gold chain
