When I saw this, I said to myself "Self ! We don't know anything about
decagons.", and then I went searching online for stuff about decagons.
This just goes to show how stupid I can be when I don't take a little time
to THINK before I go running around screaming.
-- When you draw all the lines from the center to the vertices of the
decagon, you'll have 10 little triangles.
-- The area of the whole thing is 161 square inches, so the area of each
little triangle is 1/10 of that . . . . . <em>16.1 square inches</em>.
-- The area of each little triangle is (1/2) (base) (height), just like
every other triangle.
The base is the 4.6 inches of one side of the decagon.
Area = (1/2) (base) (height)
Multiply each side by 2: 2 x area = (base) x (height)
Divide each side by (base): (2 x area) / (base) = height
Height = (2 x 16.1) / (4.6) = <em>7 inches</em> .
Let that be a lesson to both of us.
THINK before you jump.

If there is a higher concentration of solutes outside of the cell than inside it, such as would happen if you placed red blood cells in a concentrated salt solution, then the salt solution is hyper-tonic with respect to the inside of the cells. So yes the Red Blood cell would be considered a hyper-tonic solution

I added 18 to 161 and got 176 then I divided 176 by 11 an got 16 then to check my answer I multiplied 11 by 16 and got 176
