Answer: If you multiply or divide both sides of an inequality by the same negative number, you must swap the inequality symbol for the statement to still be correct.
Additionally: The absolute value of -200 is 200.
Answer:
2 3/4
Step-by-step explanation:
Answer:
15 minutes
Step-by-step explanation:
distance = rate · time
16 = 20r
r = 16/20 or 4/5 miles per minute
12 = 4/5·t
4t = 12·5
t = 60/4 or 15 minutes
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
190+135+220=445. 360(the degrees in a circle)/445(the number of students)=0.81. Each student is worth 0.81 degrees. 0.81x190(the number of students that like the program)=135.9. That rounds up or 136 so the answer is 136 degrees.
