Recall that Venn diagrams show all of the possible relationships between groups of things. Let’s create a Venn diagram illustrating the age at which people legally earn the following privileges and rights in the U. S. : • Drive • Smoke • Gamble and Drink in Las Vegas
Drive Smoke 18 19 20 Ages: 5 12 16 17 18 19 20 21 22 98 21 16 22 98 5 12 Gamble and Drink 17

US – 93 The length of each side of a rhombus is 10 cm and m A = 60°. Find the length of the longer diagonal, AC. You will need to use the properties of a rhombus to get all the data you need. (rhombus diagonals bisect the s. ) B 10 cm C 10 cm m BAC = 30° A ° 30 60° 10 cm D (rhombus the diagonals are . ) AC BD 30°-60°-90° SL: n = 5 cm LL: Hyp: 2 n = 10 cm (Parallelogram diagonals bisect each other)
a) Graph each of the following equations on the same set of axes. Darken in the region bounded by all four lines. US – 94 y b) Find the lengths of each of the sides of MATH. (Pythagorean Thm. ) T A H M MA = 5 units TH = 5 units AT = 5 units MH = 5 units c) What type of quadrilateral is MATH? Why? MATH is a rhombus by definition because all xfour sides are congruent. d) Draw the diagonals of MATH and write the equation for each diagonal.
Think about the scientific classifications of animals you learned in biology: Kingdom Phylum Class Order Family Genus Species Most general Most specific Phylum Class Order Family Genus Species
For example, humans are classified as such: Animalia Where would you place the following? Chordata Mammalia Primates Hominidae Homo Sapien
