There are 35,783 police officers in the city. 1/5 of them are females. There are about ___ male police officers in the city.
Answer:
7156.6 Women. 28624 Men.
Step-by-step explanation:
I used a web browser and typed "35783/5" That answers the woman part. "4/5 of 35783" Solves the male part.
There are about 4/5th = 28626 male police officers in the city.
What is a percentage?Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole.
Given, there are 35,783 police officers in the city.
1/5 of them are females.
That means, 1/5th = 20%
20% are female police officers.
And 100 -20 = 80% are the male police officers.
To find the number of male police officers:
80% of 35,783
= 35783 x 80 / 100
= 28626.4
= 28626 approximated
Therefore, 4/5th male police officers in the city are 28626.

Use quadratic equation.
(-b+-[tex]\sqrt{b^2-4ac}[/tex])/2a
(2+-[tex]\sqrt{(-2)^2-4*1*-2}[/tex])/2
(2+-[tex]\sqrt{(4+8})[/tex])/2
(2+-[tex]\sqrt{12}[/tex])/2
Solution 1: (2+2[tex]\sqrt{3}[/tex])/2=1+1[tex]\sqrt{3}[/tex]
Solution 2: 1-[tex]1\sqrt{3}[/tex]
Let's first move everything, the constants and variables to one side
[tex]x^2-2=2x[/tex] ⇒ [tex]x^2-2x-2=0[/tex]
The second form is in the general form of the quadratic equation:
⇒ [tex]ax^2+bx+c = 0[/tex]
a ⇒ 1b ⇒ -2c ⇒ -2To find the value of x, we can use the quadratic formula:
⇒ look at the diagram attached
[tex]x = \frac{-b-\sqrt{b^2-4ac} }{2a} =\frac{2-\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2-\sqrt{4+8} }{2} =\frac{2-\sqrt{12} }{2} =\frac{2-2\sqrt{3}}{2} =1-\sqrt{3}[/tex]
[tex]x = \frac{-b+\sqrt{b^2-4ac} }{2a} =\frac{2+\sqrt{(-2)^2-4(1)(-2)} }{2*1} =\frac{2+\sqrt{4+8} }{2} =\frac{2+\sqrt{12} }{2} =\frac{2+2\sqrt{3}}{2} =1+\sqrt{3}[/tex]

25. Anthropologists use a linear model that relates human femur (thighbone) length to height. The model allows an anthropologist to determine the height of an individual when only a partial skeleton (including the femur) is found. Here we find the model by analyzing the data on femur length and height for the eight males given in the following table.
(c) An anthropologist finds a human femur of length [tex]53 \mathrm{~cm} .[/tex] How tall was the person?
The height of the person when an anthropologist finds a human femur of length will be 183.94cm.
How to calculate the height?In order to calculate the height, the expression to use will be:
h = 1.876l + 84.512
h = 1.876(53) + 84.512
h = 99.428 + 84.512
h = 183.94
Therefore, the height is 183.94cm.

Graph a line with a slope of 4 that contains the point (3, 0)
[tex]\text{view explanation pls}[/tex]
Calculation ↓The first step is to write the line's equation in point-slope form
y-y1=m(x-x1)
y-0=4(x-3)
use the distributive property
y-0=4x-12
y=4x-12
Now that we have the equation of the line, we need to determine it's graph. how do we actually graph the line?Well, let's start with the y-intercept, which is -12 or (0, -12)
After plotting the point (0, -12) move up 4, over 1, up 4, over 1, up 4, over 1.
Do the same on both sides of the y-intercept.

I think this would be your solved equation, -3x+5 making your X intercepts at: (5/3, 0) and your Y intercepts at: (0, 5)
The equation has Unique Solution.
What is solution of equation?The solution to a linear equation is the point at which the lines that represent the intersection of two linear equations are defined. In other words, the solution set for the system of linear equations is the set of all possible values for the variables that satisfy the given linear equation.
There are three ways to solve the set of linear equations.
Unique Solution, No Solution and Infinitely Many Solutions.
Given y = 1/2x - 2
x 0 4
y -2 0
y = -3x + 5
x 0 2
y 5 -1
the graph is attached
solving by substitution
y = 1/2x - 2
y = -3x + 5
both equations are equal for y
1/2x -2 = -3x + 5
1/2x + 3x = 5 + 2
7/2x = 7
x = 2
and at x =2 y = -1
equation intersect at (2, -1) and have unique solution.

Answer:
x=19, y=[tex]19\sqrt{3}[/tex]
Step-by-step explanation:
This triangle is a 30-60-90 triangle.
This means the hypotenuse (38) is double the short leg (x)
x=19
Then use the pythagorean theorem
a^2+b^2=c^2
19^2+y^2=38^2
361+y^2=1444
Subtract 361 from both sides
y^2=1083
put it in square roots and simplify
[tex]\sqrt{1083} =19\sqrt{3}[/tex]
y=[tex]19\sqrt{3}[/tex]
To solve this problem:
⇒ need to use a special right triangle theorem:
Let's consider the information given:
⇒ one angle is 30 degrees
⇒ one angle marked with a little square signifies that it is 90
degrees
⇒ (all the angles added up are 180 degrees) so the last angle is
60 degrees
Therefore we have a '30-60-90' triangle which states:
the side opposite the 30-degree angle⇒ half the length of the hypotenuse (longest side of the triangle)
⇒ x = 38/2 = 19
the side adjacent to the 30-degree angle⇒ is the square root of 3 divided by 2 of the hypotenuse
⇒ y = [tex]\frac{\sqrt{3} }{2} *38=19\sqrt{3}[/tex]
Therefore:
x = 19
y = [tex]19\sqrt{3}[/tex]
