Three yards of fabric will be cut into pieces so that each piece is 8 inches long . How many pieces can be cut
2 answers:
<h2>Answer</h2>
13 pieces
<h2>Explanation </h2>First, we are going to convert 3 yard to inches, and then divide the result by length of each piece (8 inches)
To convert 3 yards to inches, we are going to take advantage of the fact that 1 yard = 36 inches, so:
Now we just need to divide 108 inches by the length of each piece (8 inches) to get the number of pieces:
Since we need whole pieces, we can get rid of the decimal part to get 13 pieces.
We can conclude that we can cut 13 pieces of 8 inches from three yards of fabric.

So the car is moving at 651 revolutions per minute, with wheels of a radius of 18inches
so, one revolution, is just one go-around a circle, and thus 2π, 651 revolutions is just 2π * 651, or 1302π, the wheels are moving at that "angular velocity"
now, what's the linear velocity, namely, the arc covered per minute
well
now, how much is that in miles/hrs? well
let's keep in mind that, there are 12inches in 1foot, and 5280ft in 1mile, whilst 60mins in 1hr
thus
notice, after all the units cancellations, you're only left with mi/hrs
