Atruncated cube is a convex polyhedron with 36 edges and 24 vertices. a truncated tetrahedron is a convex polyhedron with 18 edges and 12 vertices. how do the number of faces of a truncated cube and a truncated tetrahedron compare? a)the truncated cube has 6 more faces than the truncated tetrahedron. b)the truncated cube has 8 more faces than the truncated tetrahedron. c)the truncated cube has 12 more faces than the truncated tetrahedron. d)the truncated cube has 18 more faces than the truncated tetrahedron.

the first one, all those points on the line just make a strait line.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
