<span>Answer:
Every polynomial function of degree n≥1 with complex coefficients has n complex toots. A solution repeated n times counts as n roots.</span>
Percent means parts out of 100
85%=85/100=0.85
'of' means multiply
therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20
the number is 20
The volume of the sphere is 
Explanation:
Given that the diameter of the toy ball is 12.5 inches
We need to determine the volume of the toy ball.
The radius of the toy ball is given by



Thus, the radius of the toy ball is 6.25 in
The volume of the sphere can be determined using the formula,

Substituting the values, we get,

Multiplying, we get,

Substituting
, we have,

Simplifying, we get,

Thus, the volume of the sphere is 
The area of the associated sector is: 120π
<h3>What is a sector?</h3>
A sector is the portion of the area of a circle surrounded by an arc and two radii.
Analysis:
Area of a sector = ∅/360 x π
∅ = 75°
r = 24 units
Area of sector = 75/360 x π
= 120
square units
In conclusion, the area of the associated sector is 120π square units
