First, I am assuming the question should read, "how many MORE vertices ...". Step one, should always be to draw a diagram, so you can see what is going on. A rectangular prism, is a 3 dimensional shape created with two identical rectangles, joined together with straight lines - another name for … Read more

In the equation Y = MX + C, M is the slope, so you can rearrange your equation to read the same way. 3X + 4Y = 1 4Y = -3X + 1 Y = (-3X)/4 + 1/4 Now this is in the form Y = MX + C, where M = -3 So your … Read more

I assume you mean, what does circumference mean? Circumference is the special name given to the perimeter of a circle.  It's like saying square versus rectangle.  A square is a rectangle, but by saying square you are also saying four sides of equal length, four 90 degree angles. By saying circumference rather than perimeter, you are saying … Read more

Statistics themselves don't lie, however, an individual can 'tailor' questions to lean towards a specific trend or answer.  Also, depending on how the results are presented visually will also affect how people absorb the information.  This is particularly the case when representing information by for example bar charts.  By increasing the 'length of units' on the access for … Read more

Well since your width is fixed at 20 cm (and there are two of these in a rectangle) this will account for 40cm of your perimeter. Take 40 cm away from 88 cm and you get 44 cm (this accounts for both your lengths, so divide this by two) 44/2 = 22cm.  This tells you that … Read more

First understand that every circle is 360 degrees no matter it's size. So if you want to divide it into 10 equal parts, you need to know the number of degrees for each part. That would be 360/10 or 36. So, draw a radius anywhere in your circle, measure 36 degrees to get your next … Read more

What this question tells you is that 63 employees represent 90%.  Since you want to know the total number of employees you want to establish what 100% is. 63 = 90% 63/90 = 1% (63/90) x 100 = 100% 0.7 x 100 = 100% 70 = 100% This tells you that there is a total of … Read more

This is definitely a skill that is learned through practice and use, however, there are a few things you can do. Step 1. Read the question first to get 'an idea' of what is being asked. Step 2.  Where relevant (or whenever possible) draw a diagram to represent the question. Step 3.  Read the question again, underlining … Read more
