12.9/ .6= is 21.5 hope this is what you need!!:)
The most important thing in this problem is understanding and then dividing the given units properly. The first thing that is given is that the CD makes 58 1/2 revolutions in 3/4 minutes. We have to first simplify the number of revolutions made by the CD. This will make the problem in hand very easy.
Number of revolutions made by the CD = 58 1/2
= 117/2
Then
The unit rate = (117/2)/(3/4)
= (117 * 4)/(2 * 3)
= (117 * 2)/3
= 39 * 2
78
So the unit rate is 78 revolutions per minute.
There are 52 cards in a deck of cards so that makes 52 your denominator. There are 4 aces in a deck of cards, so 52 - 4 = 48 making 48 your numerator. so the probability the card won't be an ace is 48 out of 52.
48/52 chance that the card will not be an ace.
Hope this helps you. :-)
Thanks, you have a great day and a merry Christmas too
Convert to slope-intercept form, y = mx + b.
12 = 4x - 6y
Subtract 4x to both sides:
12 - 4x = -6y
Divide -6 to both sides:
y = 2/3y - 2
Now its in slope-intercept form, y = mx + b, where 'm' is the slope.
So the slope is 2/3.
