Answer:
L = 25 m
Step-by-step explanation:
L = 4W - 3
perimeter = 2(L + W)
64 = 2(4W - 3 + W)
divide both sides by 2:
32 = 5W - 3
add 3 to each side:
5W = 35
divide both sides by 5:
W =7
L = 4(7) - 3 = 25

One number is 60 more than another. If the larger number is divided by the smaller number, the quotient is 4.
What are the numbers?
Answer:
80 and 20
Step-by-step explanation:
Let the 1st no. be 'x'.
2nd no. should be 'x + 60'.
If the larger no.(x + 60) is divided by the smaller number(x), the quotient is 4.
=> (x + 60)/x = 4
=> x + 60 = 4x
=> 60=4x-x
=> 60=3x
=> 60/3 = x
=> 20 = x
No. are x = 20 and x+60 = 20+60= 80

(Please help me)
Answer:
1 7/12 cups
Step-by-step explanation:
1/2 x 3 1/6 = 1/2 x 19/6 = 19/12 or 1 7/12
For 1 he uses half cup
For 3 1/6 of the same recipe
He would use:-1/2*3 1/6
19/12 cup of vinegar
=1 7/12(Answer)

How does the mean compare to the median? How do the values of 7 and 9 affect these measures of center?
Sorry I suck at taking pictures, and math apparently.
Answer:Bueno, normalmente en los artículos semanales intento transmitir dudas o cuestiones que están en el campo, los trending topics del sector porcino, y está claro que la estadística no es uno de ellos, pero precisamente ayer se dio una situación que me llevó a escribir ésta entrada.
Todos los que trabajamos en el sector porcino estamos acostumbrados a manejar y calcular un montón de datos que nos proporciona el programa de gestión, y en muchas ocasiones realizamos pequeñas (o grandes) pruebas, donde manejamos infinidad de números (pesos, GMD, IC etc…)
Lo que sí es cierto, es que la mayoría de nosotros usamos siempre la media como herramienta fundamental. Media de Nacidos vivos, Media de destetados, Media de peso al nacer, media de peso al destete…..media, media, media…y ¿qué tal si usáramos la Mediana?
Éste fue el debate que tuve ayer con un ingeniero agrónomo (si, si, y yo Veterinaria, diversión asegurada), y el que me ha inspirados para hoy.
Para el que, en estos momentos, esté rebuscando en los archivos de su cerebro, “yo esto lo sabía”, un pequeño recordatorio:
La media o promedio, Se interpreta como “punto de equilibrio” o “centro de masas del conjunto de datos. Es un cálculo muy sencillo en el que intervienen todos los datos. Consiste en el sumatorio de todos los datos dividido por el número de valoresLa mediana, en cambio, es un valor de la variable que deja por debajo de sí a la mitad de los datos, y por encima, la otra mitad.( una vez que estos están ordenados de menor a mayor). Se sitúa, por lo tanto, en la mitad real de los datos.
Es mucho más difícil de calcular:
Con un ejemplo se entiende muchísimo mejor.
Imaginaos una empresa en la que la mayoría de los trabajadores tienen un sueldo de 1000 euros, excepto 2 encargados que cobran 2000 y el jefe que cobra 6000 euros mensuales.
¿Cuál es el salario medio de la empresa?
Si vemos la media sale casi 2000 euros, si miramos la mediana, nos da 1000.
¿Cuál se aproxima más a la realidad?
Cuando los datos son muy homogéneos la media nos da un valor representativo de la realidad, pero cuando los datos son muy heterogéneos no.
Un ejemplo más cercano a nosotros
Queremos saber el peso de los lechones a destete. Imaginemos que la camada A tiene los siguientes pesos: (4-3-5-4.5-6.1-5-3-5.1-6.4-6-6.5-5.5-4.9).

Question: Based on the data set above for the hours per day sixth graders spend using an electronic device, what is the mean number of hours sixth graders use an electronic device?
No links, useless words, or anything like that. I will report you.
Answer:
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
1+1+1+1+2+3=9
2+4+4+5+6+6+7+8+8=50
50/9=5.55555555556
or
9/50=0.18

Answer:
169.56
Step-by-step explanation:
The formula for finding the volume of a cylinder is: πr²h
First step: Plug in the radius and height: π•3²•6
Second step: Plug 3.14 for π: 3.14•3²•6
Third step: Simplify the equation: 3.14•9•6
Fourth step: Multiple to get your final answer: 3.14•9=28.26•6= 169.56
Will mark brainliest if done within 20 minutes of this being posted! NO LINKS NO FILES. Solve the radical equations and show your work, check your solutions too.
Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
whats the slope using Rise/Run?
thanks, if you help
Answer:
the slope of the given line is m = rise / run = -1/2
Step-by-step explanation:
Going from (1, -1) to (3, -2), the 'rise' is actually a drop of 1 unit; the 'run' is +2.
Thus, the slope of the given line is m = rise / run = -1/2
Use the long division method to find the result when 4x^3+23x^2 + 21x + 30 is
divided by x +5.
Answer:
A polynomial is an algebraic expression made up of two or more terms subtracted, added, or multiplied. A polynomial can contain coefficients, variables, exponents, constants, and operators such as addition and subtraction.
It is also important to note that, a polynomial can’t have fractional or negative exponents. Examples of polynomials are; 3y2 + 2x + 5, x3 + 2 x 2 − 9 x – 4, 10 x 3 + 5 x + y, 4x2 – 5x + 7) etc. Like number, polynomials can undergo addition, subtraction, multiplication, and division.
We saw addition, subtraction, multiplication, and long division of polynomials previously.

A trapezoid has a height of 3 meters, a base length of 8 meters, and an area of 30 square meters. What is the length of the base?
Answer:
Length of the second base will be 12 meters.
Step-by-step explanation:
Area of a trapezoid is given by the formula,
Area = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, b₁ and b₂ are the bases of the trapezoid and 'h' is the vertical distance between the bases.
By substituting the values in the formula,
[tex]30=\frac{1}{2}(8+b_2)3[/tex]
[tex]60=3(8+b_2)[/tex]
[tex]20=8+b_2[/tex]
[tex]b_2=12[/tex]
Therefore, length of the second base will be 12 meters.
