Answer:
n = 30
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 180 when x = n, then
180 = kn ( divide both sides by n )
k =
y = x ← equation of variation
y = n when x = 5, thus
n = × 5 = ( multiply both sides by n )
n² = 900 ( take the square root of both sides )
n = = 30
Hello,
if we use Heron's formula:
p=(7.2+5.9+11.2)/2=12.15
Area=√(p*(p-a)(p-b)(p-c))
=√(12.15*(12.15-7.2)(12.15-5.9)(12.15-11.2))
=√357,09609375
=18,896986366878714557972599553433≈18.90
So i suppose Answer=D (with an error of 0.01)
