La densidad de un líquido es de 1.5 gr/cm3 su masa es de 7 libras Determina la cantidad de litros que ocupan dichos líquidos
Answers
Answer:
La cantidad de litros que ocupa dicho líquido es:
2,12 LitrosStep-by-step explanation:
El volumen de un líquido puede obtenerse al tener tanto su densidad como su masa usando la siguiente fórmula:
Densidad = masa / volumenAl despejar volumen se obtiene:
Volumen = masa / densidadPor lo cual, si se reemplazara la fórmula quedaría:
Volumen = 7 Lb / 1.5 gr/cm^3Sin embargo, para operar, las unidades en las que se expresa la masa deben coincidir con las unidades de la densidad, por lo cual vamos a convertir las libras en gramos teniendo en cuenta el siguiente factor de conversión:
1 libra = 453,592 gramos
Entonces:
7 lb = 453,592 gr * 7 = 3175,144 gr
Ahora este valor reemplaza la masa en la fórmula y calculamos:
Volumen del líquido = 3175,144 gr / 1.5 gr/cm^3Volumen del líquido = 2116,762667 cm^3 (He utilizado todos los decimales para obtener el resultado exacto).A simple vista ya se tiene el volumen del líquido en cuestión, sin embargo, el ejercicio pide que sea expresado en litros, por lo cual vamos a convertir los centímetros cúbicos en litros teniendo en cuenta el siguiente factor de conversión:
1 litro = 1000 centímetros cúbicos.
Ahora podemos aplicar una regla de tres simple, si:
1000 cm^3 = 1 L2116,762667 cm^3 = xY operamos:
x = (2116,762667 cm^3 * 1 L) / 1000 cm^3x = 2,116762667 LO si quieres un valor aproximado:
x = 2,12 Litros.Entonces, la cantidad de litros teniendo en cuenta la densidad y la masa brindadas es 2,12 litros.

Stretched vertically about the x-axis by a
factor of 3
Reflected in the x-axis
Translated 4 units right and 2 units down
Answers
Answer:
y = -3/(x-4) - 2
Step-by-step explanation:
3*y(x) vertically stretches y by a factor 3
-y(x) reflects y over x-axis
y(x-4) translates y 4 units to the right
y(x) - 2 translates y 2 units down
Applied the transformations we get:
y(x) = 1/x → 3/x → -3/x → -3/(x-4) → -3/(x-4) - 2

WILL MARK BRAINLIEST! Identify and explain each example as Newton’s First, Second, or Third law of motion. I pull on the Earth because Earth pulls on me. Answer 1 Choose... The velocity of a falling object isn’t constant because Earth’s gravity exerts a force on it. Answer 2 Choose... If air resistance is ignored, the acceleration of a falling object is equal to the ratio of the force of gravity to mass. HELP PLZ!!!
Answers
Answer:
1.) Newton 3rd law
2.) Newton 1st law
3.) Newton 2nd law.
Step-by-step explanation:
1.) I pull on the Earth because Earth pulls on me. This can be identified as Newton 3rd law of motion. The law state that, in every action, there must be equal and opposite reaction.
As the earth pulls on you, the reaction to that action which is equal and opposite is you pulling back on earth.
2.) The velocity of a falling object isn’t constant because Earth’s gravity exerts a force on it. This can be identified by Newton 1st law of motion which state that: an object will continue to be at rest or in a linear motion except an external force act on it.
The velocity of a falling object suppose to be constant if there is no external force. But it isn’t constant because Earth’s gravity exerts a force on it.
3.) If air resistance is ignored, the acceleration of a falling object is equal to the ratio of the force of gravity to mass. This can be identified by Newton 2nd law of motion which state that: The rate of change in momentum is proportional to the applied force. Or
F = ma
Where F = applied force
M = mass of the object
a = acceleration
If air resistance is ignored,
F = mg
where g = acceleration due to gravity.

Express 3*(4*5) as a common fraction given a*b= ab/a+b .
Answers
Answer:3 ⋅ ( 4 ⋅ 5 ) = 23 a ⋅ b = a ( b a ) + b = a = 2
Step-by-step explanation:
The common fraction for the given expression is 60/47.
What is a fraction?A fraction represents part of a whole. When something is broken up into a number of parts, the fraction shows how many of those parts you have.
Given that an expression, 3*(4*5) such that, a*b= ab/a+b
Solving the expression as per the given formula,
4*5 = 4×5/(4+5) = 20/9
Now,
3*(4*5) can be written as, 3*20/9
Therefore,
3*20/9 = 3×20/9/(3+20/9)
= 20/3×9/47
= 60/47
Hence, the common fraction for the given expression is 60/47.

The weights of professional wrestlers are approximately normally distributed with a mean of 220 pounds and a standard deviation of 7 pounds. Using the normalcdf function on your graphing calculator, approximately what percent of wrestlers have weights less than 205 pounds?
Answers
Answer:
1.6%
Step-by-step explanation:
The cumulative distribution function (CDF) of a random variable X is denoted by F(x), and is defined as
F(x) = P(X ≤ x). where x is the largest possible value of X that is less than or equal to x
z = (x-μ)/σ,
where:
x is the raw score = 205
μ is the population mean, = 220 pounds
σ is the population standard deviation = 7 pounds
205 -220/7
z = -15/7
z = -2.1428571429
Using the normal cdf function on your graphing calculator,the cumulative distribution is
normalcdf( -2.1428571429, 100)
= 0.01606229
In percent form = 0.01606229 × 100

On a coordinate plane, a curve approaches the y-axis in quadrant 2 and then increases into quadrant 1. It crosses the y-axis at (0, 2).
Answers
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
Given:
[tex]f(x)= 2^{-x}=\frac{1}{2^x}[/tex]
In the above choices it is clearly defined from the above equation that output rises in the first quadrant, the value of f(x) tends to be zero and increases into another second quadrant. For x = 0, y, once again, has become 1, that is the function passes the y platform at (0,1). Therefore an exponential function reaches y = 0 in quadrant 1 on a coordinate plane and rises into quadrant 2. (0,1) stage is the temperature at which the y-axis intersects.The graph of y = 2ln(x) is (b) on a coordinate plane, a curve starts in quadrant 4 and then curves up into quadrant 1 and approaches y = 5. It crosses the x-axis at (1, 0).
How to determine the graph of the equation?The equation of the graph is given as:
[tex]y = 2\ln(x)[/tex]
Start by plotting the graph of [tex]y = 2\ln(x)[/tex] .
From the graph (see attachment), we have the following highlights
The curve of the graph starts at the 4th quadrantIt moves up to the 1st quadrantIt crosses the x-axis at x = 1, and it approaches y = 5From the list of given options, only option (b) describes the above highlights
Hence, the graph of y = 2ln(x) is (b)

Answer:
A.
[tex]Point\ C = (2,-1)[/tex]
Step-by-step explanation:
Given
[tex]A = (2,-6)[/tex]
[tex]B = (10,2)[/tex]
[tex]m:n = 5:3[/tex]
Required
Determine the coordinates of C
Since, point D divides line AB in ratio, 5 : 3;
We start by calculating the coordinates of D;
This is done as follows;
[tex]D(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]
Where
[tex](x_1,y_1) = (2,6)[/tex]
[tex](x_2,y_2) = (10,2)[/tex]
[tex]m:n = 5:3[/tex]
[tex]D(x,y) = (\frac{5 * 10 + 3 * 2}{5+3},\frac{5 * 2 + 3 * -6}{5+3})[/tex]
[tex]D(x,y) = (\frac{50 + 6}{8},\frac{10 - 18}{8})[/tex]
[tex]D(x,y) = (\frac{56}{8},\frac{-8}{8})[/tex]
[tex]D(x,y) = (7},-1)[/tex]
Since AC is vertical
Then, Point C has the same x coordinate as A
[tex]x-coordinate = 2[/tex]
Similarly;
Since CD is horizontal
Then, Point C has the same y coordinate as D
[tex]y-coordinate = -1[/tex]
Hence,

For her birthday, Samantha received a gift card, with a value of $200, to a department store. She wants to purchase at least 5 articles of clothing for work. At the store, sweaters cost $24.49 each and dress pants cost $36.99 each. If Samantha does not spend more than the amount on the gift card, which system of inequalities could be used to determine the number of sweaters, s, and the number of dress pants, p, she can buy? A. s + p $200 B. s + p > 5 $24.49s + $36.99p 5 $36.99s + $24.49p < $200
Answers
Your answer choices are a bit jumbled and some symbols are missing. However, the answer will involve the two inequalities
[tex]s+p \ge 5 \ \text{ and } \ 24.49s+36.99p \le 200[/tex]
The first inequality is the idea where she wants to buy at least 5 articles of clothing. The expression s+p is the total amount of sweaters and pants purchased, and we want this quantity to be 5 or larger.
The second inequality has the total amount spent (24.49s+36.99p) to be at most 200 dollars. In other words, we want the amount spent to be $200 or less.
24.49s = amount spent on just the sweaters
36.99p = amount spent on just the pants
24.49s+36.99p = total amount spent
