I have a pile of socks which contains 12 white socks, 12 black socks, and 12 red socks. How many socks must I take from the pile to be certain that I have at least one matching pair?
Answer:
I would say 6 but i do not know
Step-by-step explanation:
bc 6x2=12
The least number of socks to be taken from the pile to have one pair of socks is given by the equation A = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of socks to be taken be represented as A
Now , the equation will be
The number of white socks = 12
The number of black socks = 12
The number of red socks = 12
So , let the first sock be taken be either a white , black or red
Now , the second sock can also be either a white , black or red
And , the third sock can also be either a white , black or red
But , the fourth sock must a white or black or red and it will form a pair of similar colored sock
Therefore , the number of times is 4
Hence , the number is 4

So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser

En la tienda de mascotas "Animalo-T", se desea elevar un elefante de 2,900 kg utilizando una elevadora hidráulica de plato grande circular de 75 cm de radio y plato pequeño circular de 13 cm de radio. ¿Calcula cuánta fuerza hay que hacer en el émbolo pequeño para elevar al paquidermo?
Answer:
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
Step-by-step explanation:
Por el Principio de Pascal se conoce que el esfuerzo experimentado por el elefante es igual a la presión ejercida por el plato pequeño. Es decir:
[tex]\frac{F_{1}}{A_{1}} = \frac{F_{2}}{A_{2}}[/tex] (1)
Donde:
[tex]F_{1}[/tex] - Fuerza experimentada por el elefante, medida en newtons.
[tex]F_{2}[/tex] - Fuerza aplicada sobre el plato pequeño, medida en newtons.
[tex]A_{1}[/tex] - Área del plato grande, medida en metros cuadrados.
[tex]A_{2}[/tex] - Área del plato pequeño, medida en metros cuadrados.
La fuerza aplicada sobre el plato pequeño es:
[tex]F_{2} = \left(\frac{A_{2}}{A_{1}} \right)\cdot F_{1}[/tex]
La fuerza experimentada por el elefante es su propio peso. Por otra parte, el área del plato es directamente proporcional al cuadrado de su diámetro. Es decir:
[tex]F_{2} = \left(\frac{D_{2}}{D_{1}} \right)^{2}\cdot m\cdot g[/tex] (2)
Donde:
[tex]D_{1}[/tex] - Diámetro del plato grande, medido en centímetros.
[tex]D_{2}[/tex] - Diámetro del plato pequeño, medido en centímetros.
[tex]m[/tex] - Masa del elefante, medida en kilogramos.
[tex]g[/tex] - Aceleración gravitacional, medida en metros por segundo cuadrado.
Si sabemos que [tex]D_{1} = 0.75\,m[/tex], [tex]D_{2} = 0.13\,m[/tex], [tex]m = 2900\,kg[/tex] y [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], entonces la fuerza a aplicar al émbolo pequeño es:
[tex]F_{2} = \left(\frac{0.13\,m}{0.75\,m} \right)^{2}\cdot (2900\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)[/tex]
[tex]F_{2} = 854.473\,N[/tex]
Se requiere una fuerza de 854.473 newtons sobre el émbolo pequeño.
