pagué 250 pesos del recibo del agua y 490 pesos de la luz pero no recuerdo cuanto pague del telefono si traia $1000 y me sobraron 74.50 pesos ¿por cuanto era el recibo del telefono?
Answers
Queremos encontrar y resolver una ecuación algebraica con los datos dados.
Veremos que se pagaron 185.50 pesos del telefono.
La información que se nos da es:
Se pagan 250 pesos de agua.Se pagan 490 pesos de agua.No se sabe cuanto se pago del telefono, representemos esto con X.Sabemos que de 1000 pesos sobraron 74.50, entonces podemos escribir:
1000 - 250 - 490 - X = 74.50
Ahora podemos resolver esto para X.
1000 - 250 - 490 - X = 74.50
260 - X = 74.50
X = 260 - 74.50 = 185.50
Así podemos concluir que se pagaron 185.50 pesos del telefono.

The volume of a rectangular prism box can be represented by the function V(x) = 2x3 + 5x2 − 3x. If the height of the box is x cm, which of the following can represent the length and width of the container?
Answers
The volume of a box is the amount of space in the box.
The expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]
The volume is given as:
[tex]\mathbf{V(x) =2x^3 + 5x^2 - 3x}[/tex]
Divide through by height (i.e x), to get the base area
[tex]\mathbf{A(x) =2x^2 + 5x - 3}[/tex]
Expand
[tex]\mathbf{A(x) =2x^2 + 6x - x - 3}[/tex]
Factorize
[tex]\mathbf{A(x) =2x(x + 3) - 1(x + 3)}[/tex]
Factor out x + 3
[tex]\mathbf{A(x) =(2x - 1) (x + 3)}[/tex]
Hence, the expressions that can represent the length and the width are: [tex]\mathbf{(2x - 1)\ and\ (x + 3)}[/tex]

If the expression 4x-3 is equal to 11 for some value of x, then what is the expression 4x-1 equal to for
the same value of x?
(1) -15
(3) 9
(2) 13
(4) -11
Answers
Step by step equation-
4x-3=11
Add three to both the three and the 11 to get the x alone.
4x=14
Divide both sides by 4.
x=3.5
Next, substitute the x in 4x-1 so the equation is now 4(3.5)-1
4 times 3.5 is equal to 14.
14-1=13

Answers
Answer:
slope of line g = -9/4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes:
m1 × m2 = -1 or [tex]m1 = -\frac{1}{m2}[/tex]
If the slope of line f = 4/9, as given the linear equation, y = 4/9x + 3/2, then the slope of line g must be -9/4. Because if you multiply both slopes, the product will be -1:
Let m1 = slope of line f = 4/9
m2 = slope of line g = -9/4
m1 × m2 = -1
[tex](\frac{4}{9}) (- \frac{9}{4})[/tex] = -1
Therefore, the slope line g = -9/4.

The difference of the square of a number and 12 is equal to 4 times that number. Find
the positive solution.
Answers
Answer:
12.3246
Step-by-step explanation:
The equation to be solved is [tex]x^{2} -10=4x[/tex]
Rearranging: [tex]x^{2} -4x-12=0[/tex]
The quadratic formula is one way to solve this equation.
[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a}=\frac{12+\sqrt{12^{2}-4*1*4} }{2*1}[/tex]
Note that only the positive variation of the quadratic formula was used. This is because it is the only variation of this formula that produces a positive result for this equation. This is not always true, so it is best to work both versions of the formula for problems like these.
[tex]x=\frac{12+\sqrt{160} }{2} =\frac{12+4\sqrt{10} }{2}=6+2\sqrt{10} =6+6.3246=12.3246[/tex]
If the negative version of the quadratic equation was used, the final (incorrect) answer would be x= -0.3246.

What is the total total amount of digits you need to number a book of 1150 pages
Answers
Step-by-step explanation: When numbering the pages of a book, which has 1,150 pages, we need: 9 one-digit numbers (from 1 – 9);90 two-digit numbers (from 10 – 99);900 three-digit numbers (from 100 – 999);151 four-digit numbers (from 1,000 – 1,150).
The total amount of digits you need to number a book of 1150 pages will be 3493 digits.
What is an arithmetic operation?It is described as the process through which we add, subtract, multiply, and divide numerical values. It has the fundamental operators +, -, and.
There are pages for the digits totaling,
Single digits : (1 - 9) = 9 pages
Double digits : (10 - 99) = 90 pages
Triple digits : (100 - 999) = 900 pages
Four digits : (1000 - 1150) = 151 pages
By summing all digit counts such as, one may determine the total number of digits.
= (9 + 180 + 2700 + 604)
= 3493 digits.
Thus, the total amount of digits you need to number a book of 1150 pages will be 3493 digits.
