Let's call the midpoint of GF M.
MF = 16/2 = 8
KF = 25.89
MK = sqrt(25.89^2 - 8^2)
MK = 24.62
MKF = 8 * 24.62 / 2 = 98.48 square units for one triangle
There are 20 of those triangles that make up the decagon.
Therefore the total area = 20(98.48) = 1969.6 which would be option C
Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
12x+1=-7
-1 -1
12x=-6
/12 /12
x=-1/2 or x=-0.5
Distribute the .15 on the right side to get:
20 + .5x + 3 + .075x
Then, combine like terms (add numbers together and add x terms together):
.575x + 23
...and that's your final answer!
The computation illustrated by the combination shows that the number of ways will be 60 ways that the roles can be filled.
<h3>How to solve the number of ways?</h3>
From the information given, Alice, Bob, Carol, David, and Edward are being chosen for the positions of president, vice president, secretary, treasurer, and publicity chair for their school’s math club and each student can take at most two roles
It should be noted that based on the information given, This can be solved through permutations and combination. Permutations and combination implies the various ways that the objects from a set can be selected without replacement in order to be able to form subsets.
Therefore, the number of ways based on the information given will be:
= 5!/2!
= (5 × 4 × 3 × 2)/2
= 60 ways
Therefore, based on the information given above, it can be deduced that the there will be 60 ways that the roles can be filled.
