Answer:
Step-by-step explanation:
Ni
Here's how I like to represent this:
Randy = 7
Randy * 2 = Ann
Ann + 3 = Janet
Janet + 5 = Donald
If we go along and fill in the blanks for each equation, we do this:
7 * 2 = 14
14 + 3 = 17
17 + 5 = 22
So Donald solved 22 problems.
Hope this helps!
Answer:
11) 75.2
12) 44.2
Step-by-step explanation:
angles formed by intersecting lines tangent to a circle are the same length.
11)
Perimeter = 2(5) + 2(12) + 2(11.4) + 2(9.2) = 75.2
12)
Perimeter = 2(4) + 2(8) + 2(5.3) + 2(4.8) = 44.2
