The equations are :

$76,436.17
Please select the best answer from the choices provided
A
B
C
D
Answer:
The answer is
a.
$75,000
Step-by-step explanation:
The face value of the 10-year term insurance policy on a 24-year-old male is $359.25 is given as follows: $75,000.
What is the face value of the insurance policy?The face value of the insurance policy is given by the equation presented as follows:
Face value = 1,000 x (Annual premium / Amount paid per $1,000 coverage )
The parameters for this problem are given as:
Annual premium = $359.25, as given in the problem.
Also, Amount paid per $1,000 coverage for 24 year old male for 10 year policy = 4.79,
Hence the face value is calculated as:
Face value = 1000 x 359.25/4.79
Face value = $75,000.

Answer:
option A : 7x - 1
Step-by-step explanation:
Area of the shaded region = [ Area of bigger rectangle] - [Area of smaller rectangle ]
Therefore, Area of bigger rectangle = length * breadth = (x - 1)(x + 5)
Therefore, Area of smaller rectangle = length * breadth = (x + 1)(x - 4)
Area of shaded region = [(x - 1)(x + 5)] - [(x + 1) ( x - 4)
= [x(x + 5) - 1(x + 5)] - [x(x - 4) + 1( x - 4)]
= [ x^2 + 5x - 1x -5] - [ x^2 - 4x + 1x - 4]
= x^2 + 5x - 1x - 5 - x^2 + 4x - 1x + 4 ....(after removing the brackets)
= x^2 - x^2 + 5x + 4x - 1x - 1x - 5 + 4.....( as (+ x^2 )and (- x^2 )get eliminated due to opposite signs)
= 9x - 2x - 1
= 7x - 1
So, option A: 7x - 1 is the correct answer.

Answer:
[tex]\sqrt{40}[/tex] or 6.32
Step-by-step explanation:
We can find the distance between two points by using this formula
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where the x and y values are derived from the given points
The points given are ( -2 , 5 ) and ( 4 , 3 )
So we plug in the x and y values of those coordinates into the distance formula
[tex]\sqrt{(4-(-2)^2+(3-5)^2} \\4-(-2)=6\\3-5=-2\\d=\sqrt{6^2+-2^2} \\6^2=36\\-2^2=4\\36+4=40\\d=\sqrt{40}[/tex]

Answer:
40 points
Step-by-step explanation:
40 + 20 = 60
100 - 60 = 40
so round three equals 40 points
Answer:
60 points in round 3
Step-by-step explanation:
Since the total is 100, and they already got 40 points (from round 1 and 2) then just subtract them from the total to find what you got in round 3.

Answer:5
Step-by-step explanation:
you need to use Pythagoreans theorem
a^2 + b^2 = c^2
said out loud it sounds like
a squared plus be squared equals c squared
The first thing to know is that C is your hypotenuse
That means it is both
The longest side of your triangleSide that is across form the 90 degree or right angleThat's the only side that really matters, when you are using the theorem. The other 2 can be switched and it won't make a difference.
for this problem
a=unknow
b=12
c=13
a^2 + 12^2 = 13^2
a^2 +(12)(12) = (13)(13)
a^2 + 144 = 169
-144 -144
a^2 = 25
take the square root of both sides
a = 5

Carmen compro 5 blusas y 4faldas por 300 Gaby adquirió 2 blusas y 6 faldas por 230cual es el precio de cada blusa y de cada falda?
Answer:
El precio de cada falda es 25.
El precio de cada blusa es 40.
Step-by-step explanation:
Un sistema de ecuaciones es un conjunto de ecuaciones con las mismas incógnitas. Un sistema de ecuaciones lineales es un sistema de ecuaciones en el que cada ecuación es lineal.
Entonces, 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.
Una solución de un sistema es una asignación de valores para las incógnitas que hace verdadera cada una de las ecuaciones. Es decir, resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.
En este caso, se debe plantear un sistema de ecuaciones, donde las variables son:
x= precio de una blusa.y= precio de una falda.Carmen compro 5 blusas y 4 faldas por 300. Esto se plantea mediante la expresión:
5*x + 4*y= 300
Gaby adquirió 2 blusas y 6 faldas por 230, expresado mediante la expresión:
2*x + 6*y=230
Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{5*x+4*y=300} \atop {2*x+6*y=230}} \right.[/tex]
En el método de sustitución se comienza con una ecuación en el sistema y se despeja una incógnita en términos de la otra incógnita. En este caso, despejando x de la primer ecuación se obtiene:
5*x= 300 - 4*y
[tex]x=\frac{300 - 4*y}{5}[/tex]
A continuación se sustituye la expresión hallada en la otra ecuación, para obtener una ecuación con una incógnita y, a continuación se despeja esa incógnita. Entonces:
[tex]2*\frac{300 - 4*y}{5} + 6*y= 230[/tex]
[tex]\frac{2}{5}*(300 - 4*y) + 6*y= 230[/tex]
[tex]\frac{2}{5}*300 - \frac{2}{5}*4*y + 6*y= 230[/tex]
[tex]120 - \frac{8}{5}*y + 6*y= 230[/tex]
[tex]- \frac{8}{5}*y + 6*y= 230-120[/tex]
[tex]\frac{22}{5}*y = 110[/tex]
y= 110 ÷ [tex]\frac{22}{5}[/tex]
y= 25
Entonces, el precio de cada falda es 25.
Por último, se sustituye el valor hallado en la expresión [tex]x=\frac{300 - 4*y}{5}[/tex] para despejar la incógnita restante:
[tex]x=\frac{300 - 4*25}{5}[/tex]
x= 40
Entonces, el precio de cada blusa es 40.
