If you think about it, an octagon is made up of 8 triangles. So you first find the area of one triangle then multiply it by 8 for the total area:
A=1/2bh
A=1/2(9.9)(12)
A=59.4
59.4 x 8= 475.2
Therefore the total area for the octagon should be 475.2 units^2
Hope this helps !
Step-by-step explanation:
STEP 1
Equation at the end of step 1
(((x3) - 22x2) + x) - 4 = 0
STEP 2
Checking for a perfect cube
2.1 x3-4x2+x-4 is not a perfect cube
<h3>Ans; x=4</h3>
The answer will be 24 23/100
9514 1404 393
Answer:
250 days
Step-by-step explanation:
If the number of drops increases by a factor of 20/8, the expected life will decrease by the inverse of that factor: 8/20.
The expected life is (8/20)(625 days) = 250 days.
