Q: 5/8 divided by 3 In math you can flip the second denominator and numerator to multiply instead of dividing. 5/8 / 3/1 = 5/8 * 1/3 When multiply fractions you just multiply across. 5* 1 = 5 8 * 3 = 24 A: 5/24http://www.enotes.com/homework-help/5-8-divided-by-3-476717Sat, 18 Apr 2015 04:58:02 PSTQ: 3/4 miles is equal to how many yards?

Q: 3/4 miles is equal to how many yards? Well first you got to know how much 1 mile is in yards. 1 mile = 1760 yards Now you simply times 3/4 with 1760. A: 3/4*1760 = 1320 yardshttp://www.enotes.com/homework-help/3-4-miles-equals-how-many-yards-46565Sat, 18 Apr 2015 01:32:03 PSTQ: How do you change a fraction into a decimal? e.g 1/3=_.___ To change...

Q: How do you change a fraction into a decimal? e.g 1/3=_.___ To change a fraction into a decimal you simply divide it. For this example you would get 0.333.. There is another method to do so, but it doesn't always apply. If it is 1/5 you could think of it being 2/10 = .2 If it is 12/25 = 48/100 = .48 To use my method you just have to make the denominator 10, 100, 1000, etc.http://www.enotes.com/homework-help/how-do-you-change-fraction-into-decima-e-g-1-3-61399Sat, 18 Apr 2015 01:22:58 PSTQ: What is 10% of $500?

Q: What is 10% of $500? To find out the answer you must multiply the two numbers together. When you are using a percentage you always move the decimal to the left by two. 10% = .10 500 * .10 = 50 A: 50http://www.enotes.com/homework-help/10-0f-500-113273Sat, 18 Apr 2015 01:18:26 PSTQ: 3/5 of what number = 15?

Q: 3/5 of what number = 15? There is multiple ways to find out the answer: The equation should be a similar form of this: [3/5]x=15 [3/5]x = 15 when solving problems with variables, you got to make the variable alone. 5*[3/5]x = [15]*5 We multiple both sides with 5 3x = 75 Now continue to simplify the left side. 3x/3 = 75/3 A: x = 25http://www.enotes.com/homework-help/3-5-what-number-15-62747Sat, 18 Apr 2015 01:15:38 PSTMathematics is in almost everything!

Mathematics is in almost everything! It is also in other school topics like science, history, and etc. As you grow up you would use math to collect your paycheck, calculating discounted prices, and even calculating how far you will drive. Math is a crucial skill that you develop more over the years.http://www.enotes.com/homework-help/why-math-such-an-important-part-our-lives-389103Fri, 17 Apr 2015 23:11:27 PSTYes, if you want to put it into y=mx + b form you move the root(2)-6 to...

Since we are working with a line, we can look at 1/3 the distance between the x points, and 1/3 the distance between the y points. We have 2 and 8 for our x values, for a distance of 6 units between them. 1/3 of 6 is 2. So the x value of our new point is 2 units away from A. We have -1 and 5 for our y values, a distance of 6 between them. 1/3 of 6 is 2. So the y value of our new point is 2 units away from A. *note* that the y values are...http://www.enotes.com/homework-help/find-point-1-3-way-from-2-5-b-8-1-477392Fri, 17 Apr 2015 17:31:26 PSTFind the point 1/3 of the way from A(2,5) to B(8,-1): These points lie...

Find the point 1/3 of the way from A(2,5) to B(8,-1): These points lie on the line y=-x+7. (The slope is m=(5-(-1))/(2-8)=-1. Use the point-slope form to get: y-5=-1(x-2) or y=-x+7.) The distance from A to B is `6sqrt(2) ` . Use the distance formula: `D=sqrt((8-2)^2+(-1-5)^2)=sqrt(72)=6sqrt(2) ` The point 1/3 from A to B lies on the line and is `2sqrt(2) ` units away from A. From A, go over two units and down 2 units to point P(4,3)....http://www.enotes.com/homework-help/find-point-1-3-way-from-2-5-b-8-1-477392#1Fri, 17 Apr 2015 15:04:29 PSTWe know that two lines are perpendicular if their slopes are mutually...

We know that two lines are perpendicular if their slopes are mutually reciprocal. Two lines with slopes m1 and m2 are perpendicular if they meet the following: m1 = -1/m2 With this in mind and, knowing the coordinates of the vertices; we just have to find the slopes of the straight lines connecting the vertices and see if they meet the above relationship. The slope of a line is: m = (y2 - y1)/(x2 - x1) The coordinates of the points: A(13; 3),...http://www.enotes.com/homework-help/given-verticies-determine-whether-not-abc-right-477300Fri, 17 Apr 2015 13:18:26 PSTFind the point 1/3 of the way from A(2,5) to B(8, -1)

To convert tons to pounds, first we convert tons in kilograms knowing that: 1 ton(metric) = 1000 kg then: 2 tons(metric) = 2 x 1000 kg = 2000 kg Now we convert kilograms into pounds, knowing that: 1 kg = 2.204622621848776 pounds then: 2000 kg = 2000 x 2.204622621848776 = 4409.245243697552 pounds So that: 2 tons(metric) ≈ 4409.25 poundshttp://www.enotes.com/homework-help/what-does-2-tons-equal-pounds-477359Fri, 17 Apr 2015 00:51:45 PSTI'll assume that the two units that you are looking at here are the...

I'll assume that the two units that you are looking at here are the imperial units of the pound and the short ton. First, we want to find the conversion for short tons to pounds, which is pretty easy to find. A reliable source tells us that: 1 short ton = 2000 pounds So, all you have to do is apply this conversion. If the number of tons is 2, and the number of pounds per ton is 2000, you can simply multiply 2 by 2000 to get the answer. So: 2...http://www.enotes.com/homework-help/what-does-2-tons-equal-pounds-477359#3Fri, 17 Apr 2015 00:40:46 PSTwhat does 2 tons equal in pounds
