Answer:
4,200
Step-by-step explanation:
Tenemos un total de:
4 libros de matemáticas
3 libros de biología
3 libros de religión
10 libros en total.
Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.
Primer libro (tenemos 10 opciones)
segundo libro (tenemos 9 opciones, porque ya colocamos un libro)
tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)
Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:
C = 10*9*8*7*6*5*4*3*2*1 = 10!
Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.
Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.
Entonces el número total de combinaciones diferentes es:
[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]

how do i solve 3x-8x=-40
Answer:
The answer is 8 below is how you do it.
Step-by-step explanation:
first combine like terms 3x-8x
then you will have 5x
then do 40/5 and you will get x=8
Ok so to solve for x you need to isolate the variable. Usually, when solving an equation the first step would be to get all of the variables of x on the same side but this equation is already set up that way. Since 3x and 8x are both of the variable x you can simply subtract them and you would be left with:
-5x=-40
Now what you want to do is completely isolate x to get it by itself in which you would divide both sides by -5. Remember *When solving an equation you must do the same math to both sides.
-5x/-5=-40/-5
x=8
So the answer would then be 8. Also remember you can always check to see if your equation is correct by plugging your answer into the original equation
3(8) - 8(8) = -40
24 - 64 = -40
-40 = -40
Hope this helped :)
Please help! Tysm if you do!
Answer:
A
Step-by-step explanation:
We can solve this problem by eliminating wrong answers
It can be b because there is no 3
It can be c because the equation would be 4+3
And it can be d because the equation would be 3x+4
so it must be a
Answer:
option A is correct
as additional page costs is not fixed so there will be any value of x with multiply by 4
and the fixed remain only one time so it remains fixed and 3 is also fixed.

Answer:
[tex]36\ feet[/tex]
Step-by-step explanation:
Assume that the shadow of an object in this problem is proportional to the height of the object. One can form the following ratio to describe the objects in this problem,
[tex](height):(shadow)[/tex]
As per the given problem, a (6) foot person casts a (1.7) foot shadow. Therefore, one can form the following ratio,
[tex]6:1.7[/tex]
It is given that there is a lighthouse that has a shadow of (10.2) feet, one is asked to find its height. Use the parameter (x) to represent the unknown; since the ratios are related, one can form a proportion to solve for(x).
[tex]6:1.7=x:10.2[/tex]
Cross products,
[tex](1.7)(x)=(6)(10.2)[/tex]
Simplify,
[tex]1.7x=61.2[/tex]
Inverse operations,
[tex]1.7x=61.2[/tex]

[tex] \boxed{x = 45°} [/tex]
Step-by-step explanation:
When two chords intersect at a point in a circle, they form arcs, along with angles at the intersection point.
To determine the angle of the arc, we must apply this geometric rule:
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex].
Since we are looking for one of the arcs, we can rearrange this formula to solve for the first arc.
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex] →
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(\overset{\frown}{BA} + \overset{\frown}{CD}) [/tex] →
[tex] 2 × Angle \: formed \: by \: chords = \overset{\frown}{BA} + \overset{\frown}{CD} [/tex] →
[tex] 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} = \overset{\frown}{BA} [/tex]
[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]
[Given]
[tex] \overset{\frown}{BA} = x° [/tex]
[tex] \overset{\frown}{CD} = 99° [/tex]
[tex] Angle \: formed \: by \: chords \: = 72° [/tex]
→
[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]
→
[tex] x° = 2 × 72° \: – \: 99° [/tex]
[tex] x° = (2 × 72°) \: – \: 99° [/tex]
[tex] x° = 144° \: – \: 99° [/tex]
[tex] \boxed{x° = 45°} [/tex]

Answer:
m<a=56
m<b=34
m<c=56
Step-by-step explanation:
The rectangle is cut into two triangles. The total of a triangles angles is 180 degrees. The triangles are right triangles which means that the right angle is 90 degrees.
You already have an angle that measures 34 degrees.
Alternate interior angles are congruent. So, the given angle is equal to m<b.
Now add 90+34=124
To get the alternate interior angles (m<a and m<c) subtract 124 from 180 which equals 56 degrees.

Cuanto costara alforbrar un cuarto de 12 pies de ancho por 15 de largo si la alfombra vale 20.80 la yarda cuadradas
Respuesta:
416
Explicación paso a paso:
El Área de la habitación:
Largo * ancho
Longitud = 15 pies
Ancho = 12 pies
Área de la habitación = Largo * Ancho
Área de la habitación = 15 pies * 12 pies
Área de la habitación = 180 pies²
Conversión del área de la habitación en patio²
Dividir el área en pies² por 9
180 pies² ÷ 9 = 20 yardas²
Costo de la alfombra por yarda cuadrada = 20.80
Costo total de la alfombra = 20.80 * 20 = 416

Step-by-step explanation:
To find the length of the line joining the two points, we are going to use the distance formula
Mathematically, we have this as;
D = √(y2-y1)^2 + (x2-x1)^2
From the question;
(x1,y1) = (-3,4)
(x2,y2) = (2,-5)
Thus, we have it that;
D = √((-5-4)^2 + ((2-(-3)^2
D = √81 + 25
D = √(106)
D = 10.3

Given:
Endpoints of a line segment EF are E(-3,8) and F(7,-7).
Point P divides the segment EF such that EP:PF = 2:3.
To find:
The coordinates of the point P.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of the points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that EP:PF = 2:3. It means the point P divides the segment EF in 2:3.
Using section formula, we get
[tex]P=\left(\dfrac{2(7)+3(-3)}{2+3},\dfrac{2(-7)+3(8)}{2+3}\right)[/tex]
[tex]P=\left(\dfrac{14-9}{5},\dfrac{-14+24}{5}\right)[/tex]
[tex]P=\left(\dfrac{5}{5},\dfrac{10}{5}\right)[/tex]
[tex]P=\left(1,2\right)[/tex]
Therefore, the coordinates of the point P are (1,2).

Lindsey made a map of her town which place in Lindsey's town is located at 4,5
Answer:
the school
Step-by-step explanation:
the point given is (4,5) so let's try to hone in on that so to speak-
with that in mind, the way that i find the easiest to answer this is by using rise over run or the crawl before you walk method
seeing as how both are practically the same i'll just go with the craw before you walk method-
so we will 'crawl' to 4 along the x axis then we'll 'walk' and stop once we reach (4,5) and at (4,5) there is the school building and since her town is also located at the same point the school building is the correct answer
good luck :)

A dealer paid $10,000 for a used car at an auction. At the dealership, a salesperson sold the car for
30% more than the auction price. The salesperson receives a commission of 5% of the dealership
price. How much commission did the salesperson receive in dollars?
A. $150
B. $650
C. $3,000
D. $12,350
Answer:
(1.3×10000)×0.05=650$
Step-by-step explanation:
It was sold for 30% more than at the auction, which means we add 30% which is 0.3 of the price at the auction so 10000 + (30/100)×10000 which equals 13000. Now take 5% which is 0.05 of 13000 to get the final answer
(x% is equal to X/100)

Write the equation of the line that passes throught the points (-1, 6) and (5, -4).
Answer:
y = -5/3x + 13/3
Step-by-step explanation:
(-1, 6) and (5, -4).
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - 6) / (5 - (-1))
Simplify the parentheses.
= (-10) / (5 + 1)
= (-10) / (6)
Simplify the fraction.
-10/6
= -5/3
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -5/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (5, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = -5/3(5) + b
To find b, multiply the slope and the input of x(5).
-4 = -25/3 + b
Now, add 25/3 to both sides to isolate b.
-4 ⇒ -12/3
-12/3 + 25/3 = 13/3
13/3 = b
Plug this into your standard equation.
y = -5/3x + 13/3
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, 6).
y = -5/3x + 13/3
6 = -5/3(-1) + 13/3
6 = 5/3 + 13/3
6 = 18/3
6 = 6
Your equation is correct.
Hope this helps!
