Answer:
The total number of registered doctors was 167,722.
Step-by-step explanation:
Total number of doctors:
The total number of doctors is given by x.
31.6% of all registered doctors were female. 53,000 female doctors.
This means that:

What was the total number of registered doctors?
We have to solve the above equation for x. So


The total number of registered doctors was 167,722.

Answer:
"complete the square" to put in vertex form
Step-by-step explanation:
It may be helpful to consider the square of a binomial:
(x +a)² = x² +2ax +a²
The expression x² +x +1 is in the standard form of the expression on the right above. Comparing the coefficients of x, we see ...
2a = 1
a = 1/2
That means we can write ...
(x +1/2)² = x² +x +1/4
But we need x² +x +1, so we need to add 3/4 to the binomial square in order to make the expressions equal:

_____
Another way to consider this is ...
x² +bx +c
= x² +2(b/2)x +(b/2)² +c -(b/2)² . . . . . . rewrite bx, add and subtract (b/2)²*
= (x +b/2)² +(c -(b/2)²)
for b=1, c=1, this becomes ...
x² +x +1 = (x +1/2)² +(1 -(1/2)²)
= (x +1/2)² +3/4
_____
* This process, "rewrite bx, add and subtract (b/2)²," is called "completing the square"—especially when written as (x-h)² +k, a parabola with vertex (h, k).
hours did it take for oil to cover the area = 592
The correct option is B.
<h3>What is geometrical figure?</h3>
Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.
<h3>According to the given information:</h3>
Given,
Area = 11000m²
Radius = .10m/h
We know the area of the circle:
Area = πr²
The relation between parameter:
Area = πr²
11000 = 3.14 * (0.10t)²
Dividing both side by 3.14
11000/3.14 = (3.14 * (0.10t)²)/3.14
by solving this we get:
(.10t)² = 3503.184
.10t = 59.187
dividing both side by 0.10
t = 59.187/.10
t = 591.877
t = 592
hours did it take for oil to cover the area = 592
