Answer:
(D) -2
Step-by-step explanation:
Plug in r=5 and s=-7 to the equation:
-6(5)+(-7)-(5)(-7)
Now we can solve and simplify:
-30-7+35
Combine:
-2
Hey there!
-6r + s - rs
= -6(5) + (-7) - 5(-7)
= -6(5) - 7 - 5(-7)
= -30 - 7 - 5(-7)
= -30 - 7 + 5
= -37 - (-35)
= -2
Therefore, your answer is: -2

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"

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

The chronological organization allows us to organize the events sequentially according to the date of their occurrence.
What is seen in the image?The image shows several tables that refer to historical events around the world that we must organize chronologically.
How to organize events chronologically?To organize the events chronologically we must know the date on which they occurred, for this we must search for complementary information and establish the date of each one of them, especially the year.
Later, we can organize them and we have two alternatives, from the most recent to the oldest or from the oldest to the most recent. In this case we are going to organize them from the most recent to the oldest, so they would look like this:

Answer:
1st and 3rd statements are true
Step-by-step explanation:
2u + 9v + 1
the constant term is the term with only a numeric value
in this case the constant term is 1
the coefficient of the term 2u is 2 ( the value in front of the variable u )
the coefficient of the term 9u is therefore 9
there are 3 terms in the expression 2u , 9v , 1
these terms are being added together , thus
2u + 9v + 1 is the sum of three terms
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
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

y=mx+c
I picked the points (0, -4) and (-2,-10) to find the gradient of the line
M= rise/run

Y-intercept is at - 4
Y= 3x - 4 is equation of the line given
Reciprocal of 3 is 1/3
(m1 x m2 = - 1)
So, to make - 1, our second gradient should be negative.
Gradient of the perpendicular line will be - 1/3
Y= - 1/3x + c
Substitute value of x & y into the equation
(-6,6) means x = - 6, y = 6
y = - 1/3x +c
6 = - 1/3 x - 6 + c
6 = 2 + c
-2
4 = c
Thus, final equation we're after will be:

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]

In an isosceles triangle the length of the base is 10 cm
The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.
How to calculate the radius?From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.
Let A = area of the triangle
Let S = semi perimeter of the triangle.
The radius will be: = A/S
where,
[tex]S = \dfrac{(a + b + c)}{2} = \dfrac{(13 + 13 + 10)}{2} = 18[/tex]
The radius will be:
[tex]=\dfrac{(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{10})} { 18}[/tex]
= 3.33cm

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
Demand and supply in a market are described by the following equations: qd = 66-3p qs = -4 2p find the equilibrium price and quantity
The equilibrium price is $14 and the quantity is 24.
What is the equilibrium price?Equilibrium is the place in the market where there is no trend for change.
Buyers’ and sellers’ plans accord, and consequently quantity demanded equals quantity supplied.
The equilibrium price occurs when the quantity demanded equals the quantity supplied.
The demand and supply functions are, respectively:
Demand and supply in a market are described by the following equations: QD = 66-3p and qs = -4 + 2p.
The equilibrium price and quantity are;
QD = QS
66-3p = -4 + 2p
66 + 4 = 2p + 3p
70 = 5p
p = 70/5
p = 14
QD = 66-3p
QD = 66-3 × 14
QD = 66- 42
