To me, it looks like your best answer would in fact be 6 people.
Hope this helps!
Answer:
x = 6
Step-by-step explanation:
Note the triangle is a right- isosceles, with equal legs = 6
Using Pythagoras' identity on the right triangle.
x² = 6² + 6² = 36 + 36 = 72 ( take the square root of both sides )
x = 
= 
= 
× = 6
Answer:
9.13385827
Step-by-step explanation:
s is a half perimeter of a triangle.
For given triangle,
s = (16+8+10) /2 = 17,
and a= 16, b=8, c=10.
Now, we can use Heron´s formula,
A=√(s(s-a)(s-b)(s-c)) = √(17(17-16)(17-8)(17-10)) = √(17*1*9*7) = √(1071) ≈ 33
A = 33 square units
The answer is 162.
sequence is arithmetic; d = 5
sum = (n/2)(a1+an)
an = a1 +d(n-1)
a12 = -14 + 5(11)
a12 = -14 + 55 ----> a12 = 41
sum: (12/2)(-14 + 41)
= 6(27)
= 162
