28 : 42 = 2 : 3
It is 3 to 2.
No. A ratio can be expressed as a fraction. 6 to 3 can be written as 6/3 which is equal to 2. 3 to 6 can be written as 3/6, which is equal to 1/2.
1080 degrees are in 3 circles. :)
Means for every 100 units of one, you add 12 units of 2. Or a 20/3 ratio (expressed in percent).
The ratio of 2 circles and 3 triangles can be expressed as : 2 : 3.
To create three different drawings showing a number of circles and triangles in which the ratio is 2:3 you can: Start with an equilateral triangle, draw a circle inside it, draw an equilateral triangle inside the circle, draw a circle in the triangle and then draw an equilateral tiangle in the smallest circle. Or, you could draw 3 triangles and 2 circles in a line. Or, you could draw 3 triangles on a line with 2 circles between them.
For each drawing . . .-- Draw a small number of circles.-- Draw that same number of circles again.-- Draw that same number of triangles three times.To create a different drawing, do exactly the same thing,but start out with a different small number.
It is the number of triangles : the number of circles.
1. circles 2. triangles 3. squares 4. any of the polygons
(11!) / (4!) (3!) (2!) (2!) = 69,300distinguishable arrangements
In 2-d, items are flat, like triangles or circles In 3-d things have height, like boxes or spheres
2 sides in same ratio and included angle all angles 3 sides in same ratio Triangles are similar if they are the same shape, with the same angles and proportions, but not necessarily the same size.
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
Their scale factor is 3 : 5, which mean their sides scale factor is 3 : 5, too. The area formula : S = bh/2 ---> The ratio of their areas : (3 : 5)^2=9 : 25 It's the answer.
That the triangles will be congruent
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
