It would be (B) because 450+200x4=2620 fence posts
Answer:
k = 3
Step-by-step explanation:
Given that y and x are directly related then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k = 
= 
= 3
Idk but it can't be 10 or 9.7 bc a triangle's hypotenuse is always longer than its legs

Answer: 11 cans</h3>
======================================================
Explanation:
SA = surface area of the sphere
SA = 4*pi*r^2
SA = 4*pi*8^2
SA = 804.247719
The surface area is roughly 804.247719 sq ft.
I used the calculator's stored version of pi to get the most accuracy possible.
Since 1 paint can covers 75 sq ft, divide that surface area over 75 to find out how many cans you need.
804.247719/75 = 10.72330292
Round up to the nearest integer to get 11
You'll have leftover paint, but it's better to go over the goal than come up short.
Answer:
X=8, each side is=27
Step-by-step explanation:
Equilateral triangle, each side has the same lenght
5x-13=11x-61
61-13=11x-5x
48=6x
x=8
5(8)-13=27
