What does the phrase rise over run refer when defining slope?
This is the fraction or number representing how many units up a line goes for ever unit it goes laterally. For example, a slope of 2/3. This line goes up two units for every three it goes sideways.
What does rise represent and what does run represent?
Rise represents the change in y-values on a graph, e.g. if the rise is equal to 10, the y-value changes by 10. Run represents the change in x-values on a graph, e.g. if the run is equal to 5, the x-value changes by 5. knowing both the rise and the run is necessary to calculate the gradient, or slope of a graph - this is done by dividing the rise by the run, in this case it would be equal to 10/5 = 2
What is the slope of a line formed by x 4 and y 2 and x 1 and y -1?
two points (4,2) and (1,-1) slope is rise of run. rise = -1 -2 = -3 run = 1 - 4 -3 => slope = -3/-3 = 1
The diagonals of the rhombus are in the ratio 3 4 the perimeter of the rhombus is 40cm find the lengths of the sides and of the diagonals?
The length of the sides of the rhombus are 10cm, as a rhombus has equal sides. since the diagonals of a rhombus are perpendicular, ratio of side of rhombus to 1/2 a diagonal to 1/2 of another diagonal is 5:4:3 (pythagorean thriple), hence ratio of side of rhombus to 1 diagonal to another diagonal is 5:8:6. since 5 units = 10cm 8 units = 16cm 6 units = 12cm and there are your diagonals.
What is the ratio of 24 mintues to 2 hours?
Well, isn't that just a happy little question! To find the ratio of 24 minutes to 2 hours, we first need to convert the hours to minutes. Since 1 hour is equal to 60 minutes, 2 hours would be 120 minutes. Therefore, the ratio of 24 minutes to 2 hours is 24:120, which simplifies to 1:5.
