Answer:
Perimeter of rectangle is 23.34
Step-by-step explanation:
The coordinates of the vertices of a rectangle are (-4, 3), (-1, 5),(3, – 1), and (0, – 3).
What is the perimeter of the rectangle?
The formula to find perimeter of rectangle is: [tex]Perimeter=2(l+w)[/tex]
We need to find length and width first using the coordinates (-4, 3), (-1, 5),(3, – 1), and (0, – 3).
Let A=(-4, 3) B=(-1, 5) C=(3, – 1) and D=(0, – 3) according to the figure attached.
So, If we find distance of point AB it can be considered length of rectangle and distance of point AC can be considered width of rectangle
The formula used to find distance is: [tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Finding distance AB, we have [tex]x_1=-4, y_1=3, x_2=-1, y_2=5[/tex]
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(-1-(-4))^2+(5-3)^2}\\Distance=\sqrt{(-1+4)^2+(5-3)^2}\\Distance=\sqrt{(3)^2+(2)^2}\\Distance=\sqrt{9+4}\\Distance=\sqrt{13}\\Distance=3.61[/tex]
So distance between point A and B is 3.61
Finding distance AC, we have [tex]x_1=-4, y_1=3, x_2=3, y_2=-1[/tex]
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(3-(-4))^2+(-1-3)^2}\\Distance=\sqrt{(3+4)^2+(-1-3)^2} \\Distance=\sqrt{(7)^2+(-4)^2} \\Distance=\sqrt{49+16} \\Distance=\sqrt{65}\\Distance=8.06[/tex]
So, distance between point A and C is 8.06
We have length = 3.61 and width = 8.06
Using formula of perimeter
[tex]Perimeter=2(l+w)\\Perimeter=2(3.61+8.06)\\Perimeter=2(11.67)\\Perimeter=23.34[/tex]
So, Perimeter of rectangle is 23.34

One pipe can fill a tank in 24 minutes, a second can fill it in 8 minutes, and a third can fill it in 12 minutes. If the tank is empty, how long will the three pipes, operating together, take to fill it?
4 4/5 minutes
4 minutes
1/6 minute
Answers
Answer:
4 mins
Step-by-step explanation:
Tank 1: 24
Tank 2: 8
Tanks 3: 12
So you add them all up to equal the "work". which is one. Looks like this:
*** x/24 + x/8 + x/12 = 1 ***
multiply all by 24
x+3x+2x=24
add like terms
6x=24
divided by 6
x=4
So x=4 minutes.

The sum of two integers is 31. The larger of the two integers is
4 more than 2 times the smaller integer. What are the integers?
Answers
Answer:
The larger is 22, the smaller is 9.
Step-by-step explanation:
We need to make the two equations for this which would be:
x+y=31
x=2y+4
we can put the second equation into the first
(2y+4)+y=31
3y+4=31
subtract 4 from each side
3y=27
divide each side by 3
y=9
put this y into our second equation
x=2(9)+4
x=18+4
x=22

∠ C = 44°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
4x - 16 +6x - 1 + 4x - 13 = 180°
14x - 30 = 180 ( add 30 to both sides )
14x = 210 ( divide both sides by 14 )
x = 15
Thus
∠ C = 4x - 16 = 4(15) - 16 = 60 - 16 = 44°

Bottle contains 64 fluid ounces of syrup. Each day, you use 3 1/5 fluid ounces of syrup from the bottle. Is there enough syrup in the bottle for 25 days?
Answers
Given:
Total syrup = 64 fluid ounces
Syrup used each day = [tex]3\dfrac{1}{5}[/tex] fluid ounces
To find:
Whether there is enough syrup in the bottle for 25 days or not.
Solution:
According to the question,
Requirement of syrup for 1 day [tex]=3\dfrac{1}{5}[/tex] fluid ounces
[tex]=\dfrac{3\times 5+1}{5}[/tex] fluid ounces
[tex]=\dfrac{16}{5}[/tex] fluid ounces
Requirement of syrup for 25 day [tex]=25\times \dfrac{16}{5}[/tex] fluid ounces
[tex]=\dfrac{400}{5}[/tex] fluid ounces
[tex]=80[/tex] fluid ounces
Syrup required for 25 days is 80 fluid ounces which is greater than 64 fluid ounces.
Therefore, 64 fluid ounces of syrup is not enough for 25 days.

The measure of the exterior angle of the triangle is
Answers
The exterior angle of a triangle is congruent to the sum of the opposite interior angles
The measure of the exterior angle of the triangle is 114 degrees
From the figure,
The interior angles are 24 and 2x + 18. The exterior angle is 3x + 6.So, the interior and exterior angles have the following relationship
[tex]\mathbf{3x + 6 = 2x + 18 + 24}[/tex]
Collect like terms
[tex]\mathbf{3x - 2x = -6 + 18 + 24}[/tex]
[tex]\mathbf{x = 36}[/tex]
The exterior angle is given as:
[tex]\mathbf{\theta = 3x + 6}[/tex]
Substitute 36 for x
[tex]\mathbf{\theta = 3 \times 36 + 6}[/tex]
[tex]\mathbf{\theta = 114}[/tex]
Hence, the exterior angle is 114 degrees

Find the x-intercept for x+8y=-9
Answers
Answer:
-9
Step-by-step explanation:
To find the x-intercept, we have to substitute 0 as y.
x + 8(0) = -9
x = -9
There ya go!
Answer:
x = - 9
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x, that is
x + 8(0) = - 9, that is
x = - 9 ← x- intercept or in coordinate form (0, - 9 )
Imagina que vas a un partido de béisbol con tus amigos, y tienen hambre. El costo de dos botellas de agua y 3 bolsas de palomitas es de $65. El costo de 4 botellas de agua y 1 bolsa de palomitas es de $55. Para saber cuánto pagaría cada uno, determina el costo de una botella de agua y de una bolsa de palomitas.
(Considera que x=agua y y= palomitas)
Answers
Answer:
El costo de una botella de agua es de $10
El costo de una bolsa de palomitas de maíz es de $15.
Step-by-step explanation:
Los parámetros dados son;
El costo de dos botellas de agua y 3 bolsas de palomitas de maíz = $65
El costo de 4 botellas de agua y 1 bolsa de palomitas de maíz = $55
Donde x = El costo de una botella de agua ey = El costo de una bolsa de palomitas de maíz, tenemos;
2 × x + 3 × y = 65 ... (1)
4 × x + y = 55 ... (2)
Haciendo y el tema de ambas ecuaciones, tenemos;
Para la ecuación (1), tenemos;
2 · x + 3 · y = 65
3 · y = 65 - 2 · x
y = 65/3 - 2/3 · x
Para la ecuación (2), tenemos;
4 · x + y = 55
y = 55 - 4 · x
Igualando ambos valores de y para encontrar la solución común, tenemos;
65/3 - 2/3 · x = 55 - 4 · x
4 · x - 2/3 · x = 55 - 65/3
10 · x / 3 = 100/3
∴ 10 · x = 100
x = 100/10 = 10
x = 10
El costo de una botella de agua = x = $10
y = 55 - 4 · x = 55 - 4 × 10 = 55 - 40 = 15
y = 15
El costo de una bolsa de palomitas de maíz = y = $15
Teniendo en cuenta la definición de sistema de ecuaciones lineales, el costo de una botella de agua es $10, mientras que el costo de una bolsa de palomitas es $15.
Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema. Es decir, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso, se debe plantear un sistema de ecuaciones lineales teniendo en cuenta que:
x= el costo de una botella de agua.y= el costo de una bolsa de palomitas.Por un lado, se sabe que el costo de 2 botellas de agua y 3 bolsas de palomitas es de $65. Esto se expresa mediante: 2x + 3y= 65
Por otro lado, se sabe que el costo de 4 botellas de agua y 1 bolsa de palomitas es de $55, expresado mediante 4x + y= 55
Entonces, el sistema de ecuaciones a resolver es:
[tex]\left \{ {{2x+3y=65} \atop {4x+y=55}} \right.[/tex]
Existiendo diversos métodos para resolver un sistema de ecuaciones, se decide resolver mediante el método de sustitución , que consiste en despejar una de las dos variables en una de las ecuaciones del sistema y sustituir su valor en la otra ecuación.
En este caso, aislando la variable "y" de la segunda ecuación se obtiene:
y= 55 -4x
Reemplazando en la primer ecuación se llega a la expresión:
2x+3×(55 -4x)=65
2x +3×55 - 3×4x=65
2x + 165 - 12x=65
2x -12x= 65 -165
-10x=-100
x= (-100)÷ (-10)
x=10
Finalmente, para obtener el valor de y se reemplaza en la expresión anteriormente obtenida para y:
y= 55 -4x
y= 55 -4×10
y= 55 - 40
y=15
Finalmente, recordando que x representa el costo de una botella de agua e y representa el costo de una bolsa de palomitas, entonces el costo de una botella de agua es $10, mientras que el costo de una bolsa de palomitas es $15.

Answers
Answer:
37.5 miles per gallon
Step-by-step explanation:
In order to calculate the mileage per gallon of the car we simply need to divide the total number of miles that the car has travelled by the total amount of gas that is used during that time. Since we are given both of these values then we can simply go ahead and use these values to find the car's gas mileage...
356.35 / 9.5 = 37.5 miles per gallon
Finally, we can see that the taxi driver's car gets roughly 37.5 miles per gallon.
