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 = ![\frac{180}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B180%7D%7Bn%7D)
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

We know that
if Anita divided a circle into 6 equal parts------> (1/6)+(1/6)+(1/6)+(1/6)+(1/6)+(1/6)
each part is --------> (1/6)
if shades 1 of the parts ----------> the part that she shaded is 1/6
the answer is (1/6)
