You can do this a couple of ways. Since slope is rise/run, you can plot the points then count up or down then back or forth to determine slope. A method that always works is plug your points into this formula (hopefully I can write it so you understand:)) y (two) - y (one)/x (...

Look at it as 40% of what amount is $20. Percent/100 = is/of 40/100 = 20/x Multiply 20 by 100, then divide by 40 So, 2000 divided by 40 will give you your answer

Area is l x w, so 400,000 x 500,000 is 200,000 and half of that is 100,000. If Kirk mows half of the 400 ft. width, then 1/2(400) is 200. If the mower mows a 5 ft. wide path, how many passes will Kirk need to make?

Basically, the number inside the / / is always positive. Only if it has a negative sign on the OUTSIDE, is it negative. The / / means "absolute value" which is simply how far away from 0 on a number line the number is. So, /-48/ is 48 spaces from 0, so it's value...

To turn a fraction into a decimal, take the denominator and slide it to the outside to make a division problem...in this case 1 divided by 5, which equals .20 To turn a decimal into a percent, move the decimal point 2 places to the right and add a percent sign. The 1 is a ...
*April 8, 2008*

**Math**

It would be 1.2 because you can find percent by dividing the numerator by the denominator....just slide the bottom number in the fraction to the outside to make a division problem then divide. 1 divided by 5 is .2. You then must put your one back in front. Hope this makes sense.

Since a pie chart represents 100%, I'd find the percentage for each and divide them up in your chart as close a possible. There are 40 total in your count, so 17 Army represents 42-43%, 10 Navy for 25%, and so on. I hope this helps:)
