Is there always 180 degrees in a triangle? Since the sum of the angles of a triangle is always 180 degrees… The two sides of the triangle that are by the right angle are called the legs… and the side opposite of the right angle is called the hypotenuse. Do all right triangles equal 180? […]

How do you know if y varies inversely as x? An inverse variation can be represented by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 . How do you determine whether Y is a function of […]

How do you find G in a simple pendulum experiment? Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find “g.” This is your […]

What is mode of a set? The mode is the value that appears most frequently in a data set. A set of data may have one mode, more than one mode, or no mode at all. Other popular measures of central tendency include the mean, or the average of a set, and the median, the […]

In which property of addition changing the group of addends does not change the sum? According to the commutative property of addition, changing the order of the numbers we are adding, does not change the sum. Here’s an example of how the sum does NOT change, even if the order of the addends is changed. […]

What is a parabolic line? In differential geometry, a smooth surface in three dimensions has a parabolic point when the Gaussian curvature is zero. Typically such points lie on a curve called the parabolic line which separates the surface into regions of positive and negative Gaussian curvature. What is the difference between a parabola and […]

What is the starting point on a graph? In mathematics, an origin is a starting point on a grid. It is the point (0,0), where the x-axis and y-axis intercept. The origin is used to determine the coordinates for every other point on the graph. Is Diagonal the same as horizontal? Horizontal lines go from […]

Is an acre a mile long? Miles and acres measure entirely different things. Miles are units of length and acres are units of area. If you think of a piece of land in the shape of a square and measures one mile on each side then its area is one square mile. In terms of […]

What impact would having old worn out Tyres have on your stopping distance? Compared to new ones, the worn tires increased stopping distances an average of 87 feet for a passenger car and 86 feet for a light truck – longer than a semi-trailer truck. Do tires affect stopping distance? The Consumer Reports wet weather […]

What is 0.1 on a number line? On a number line, divide the interval between 0 and 1 into 10 equal parts and place marks to separate the parts. Label the marks 0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0 0.1 , 0.2 , 0.3 , 0.4 , 0.5 , 0.6 , 0.7 , 0.8 , 0.9 , 1.0 . We write […]
