Which words mean the same thing as 5/8
Answer:
c) Five out of 8 equal parts of a whole
Step-by-step explanation:
The statement "Five out of 8 equal parts of a whole" means the fraction of 5/8. Hence, option (c) is the correct answer.
Answer:
"Five out of eight equal parts of a whole"
Step-by-step explanation:
In a fraction, the numerator (top part) is saying "this number out of the number below it."
The denominator (lower part) is the number below it that we are taking the proportion out of.
A denominator is ALWAYS equal parts, so if we match up the phrase: "5 out of eight equal parts of a whole"

Sarah has private health insurance that costs $575 per month. Her new employer will provide health insurance at no cost to her. What is her health insurance worth as a benefit of employment?
Based on the above information, it can be inferred that Sarah saves $6,900 per year.
How to calculate how much Sarah saves per year in health service?Taking into account that her new employer is going to give her a free health service and that before she paid $575 for the health service monthly, to calculate her savings per year we must multiply the value of the health service by the number of months of one year (12).
$575 × 12 = $6,900Based on the above, it can be inferred that Sarah is saving $6,900 per year on health care.

the vertex of triangle DEF are D(1,3) ;E(-1,0) ;F(2,-1) find the coordinate of orthocenter for this triangle
please with clear explanation I will give brainliest
Answer:
[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]
Step-by-step explanation:
The orthocenter is the point of intersection of the altitudes of a triangle.
(The altitude is the line that passes through the vertex and is perpendicular to the side opposite the vertex).
**Refer to attached diagram**
DC, EA and FB are the perpendicular lines drawn from the three vertices D, E and F.
[tex]\sf Let\:(x_1,y_1)=D\implies(x_1,y_1)=(1,3)[/tex]
[tex]\sf Let\:(x_2,y_2)=E\implies (x_2,y_2)= (-1,0)[/tex]
[tex]\sf Let\:(x_3,y_3)= F\implies (x_3,y_3)=(2,-1)[/tex]
G (x, y) is the intersection point of the three altitudes of the triangle, i.e. the orthocenter.
To find the point of intersection (orthocenter), we need to create linear equations for the altitudes, then equate them to find the point of intersection.
We only need to work with 2 altitudes.
Calculate the slopes of two sides of the triangle.
[tex]\sf \implies Slope\:of\:EF=\dfrac{y_3-y_2}{x_3-x_2}=\dfrac{-1-0}{2-(-1)}=-\dfrac{1}{3}[/tex]
[tex]\sf \implies Slope\:of\:DF=\dfrac{y_3-y_1}{x_3-x_1}=\dfrac{-1-3}{2-1}=-4[/tex]
As the slopes of the altitudes are perpendicular to the slopes of the sides:
[tex]\textsf{Slope of DC}=\sf \dfrac{-1}{\textsf{slope of EF}}=\dfrac{-1}{-\frac{1}{3}}=3[/tex]
[tex]\textsf{Slope of EA}=\dfrac{-1}{\textsf{slope of DF}}=\sf \dfrac{-1}{-4}=\dfrac{1}{4}[/tex]
Using point D (1, 3) and the slope of DC to create a linear equation for DC using the point-slope form of a linear equation:
[tex]\sf \implies y-y_1=m(x-x_1)[/tex]
[tex]\sf \implies y-3=3(x-1)[/tex]
[tex]\implies \sf y=3x[/tex]
Using point E (-1, 0) and the slope of EA to create a linear equation for EA using the point-slope form of a linear equation:
[tex]\sf \implies y-y_1=m(x-x_1)[/tex]
[tex]\sf \implies y-0=\dfrac{1}{4}(x-(-1))[/tex]
[tex]\sf \implies y=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]
To find the x-value of the point of intersection (the orthocenter), equate the equations and solve for x:
[tex]\implies \sf 3x=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]
[tex]\implies \sf \dfrac{11}{4}x=\dfrac{1}{4}[/tex]
[tex]\implies \sf 11x=1[/tex]
[tex]\implies \sf x=\dfrac{1}{11}[/tex]
To find the y-value of the point of intersection (the orthocenter), substitute the found value of x into the equation for line DC:
[tex]\implies \sf y=3\left(\dfrac{1}{11}\right)[/tex]
[tex]\implies \sf y=\dfrac{3}{11}[/tex]
Therefore, the orthocenter is at point:
[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]

The lines that appear tangent are tangent. What is the value of x, to the nearest tenth.
Answer:
x ≈ 10.7
Step-by-step explanation:
Is given in the picture that x is the radius of the circle.
The radius of a circle and the tangent line to the circle form a right angle, therefore our triangle is a right triangle.
We can apply the Pythagorean Theorem to find one equation that will have one unknown x.
(x+12)² = x² +20² , use that (a+b)² = a²+b²+2ab
x²+12²+2·x·12 = x² +20², subtract x² from both sides of the equation
12² + 24x = 20², subtract 12² from both sides of the equation
24x = 20²-12², raise to power and combine like terms
24x = 256, divide by 24 both sides of the equation
x = 10.6666666..., round to the nearest tenth
x ≈ 10.7
the length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12, what the length
Answer:
The length of the other two legs are 6√2.
since the hypotenuse is one of the legs multiplied by √2.
dividing the hypotenuse by √2 will get the length of one leg. since it is a 45 45 90 triangle, the length of the two legs are the same.
12/√2= 12√2/2= 6√2
A filing cabinet measures 5 feet is 18 inches wide and 2 feet deep what is the volume of the filing cabinet
Answer:
15 feet
Step-by-step explanation:
From the question above,we are asked to find the volume of a cabinet with the following dimensions:
Height is five feet
Width is eighteen inches
And a depth of two feet.
Here it is quite obvious that we ate dealing with a cuboidal object since its dimensions differ from one another.
So volume of a cuboid as we all know is :
Length multiplied by width and then height
We should head straight away to the calculations, but we need to remember that the width is in inches and needs to be converted to feet
1 inch = 1/12 feet
18 inches = 18× 1/12
= 1.5 feet
L×W×H
= 1.5×5×2
= 15 feet

What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a trigonometric function:
[tex]\rm y = -6\cos\left(5x\right)-3[/tex]
As we know, the range for the cosx is [-1, 1]
The maximum value of function y = -6cos(5x)—3 is 3 and minimum value is -9.
The amplitude = 6

Assuming your asking for two sets of systems of equations.
#1: [tex]{y,x}={-1,-1}[/tex]
Steps:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y - 2
// Plug this in for variable x in equation [1]
[1] y - 4•(-y -2) = 3
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
y = -1
x = -y-2
// Use the y value to solve for x
x = -(-1)-2 = -1
Solution :
{y,x} = {-1,-1}
2: [tex]{y,x}={3,-1}[/tex]
Steps:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 2
// Plug this in for variable x in equation [1]
[1] y + 6•(-y +2) = -3
[1] -5y = -15
// Solve equation [1] for the variable y
[1] 5y = 15
[1] y = 3
// By now we know this much :
y = 3
x = -y+2
// Use the y value to solve for x
x = -(3)+2 = -1
Solution :
{y,x} = {3,-1}
In a town, 15% of the population is unemployed. what is the
total population, if number of people who are employed is
8381
Answer:
1479 people
Step-by-step explanation:
If the amount employed is 8381, that means 8381 is 85% of the population. 8381/85 = 98.6
Every 1% of the population is 98.6, so we can just do 15 x 98.6 to get 1479
Answer:
9,860
Step-by-step explanation:
100% - 15% = 85 % = 85/100
85/100 * 8381/x
85x = 838,100
838,100/85 = 9,860
