If at the beginning of a game, each of 4 players was given 2 red cards. the expression that represents the total number of cards each player received is 2 + (n/4).
What is the expression?Since the green cards were distributed equally, each player initially possessed 2red cards and 4 green cards.
We must sum the number of red cards and the number of green cards to get the total number of cards each player got.
So,
Total number of cards each player received = Number of red cards + Number of green cards
Total number of cards each player received = 2 + (n/4)
Therefore the expression is 2 + (n/4).

Verónica Ana y Luis pintan una barda y les pagan 300 cuánto dinero debería recibir cada quien
Si Verónica, Ana y Luis están pintando una barda y se les paga un total de 300 unidades monetarias (por ejemplo, dólares, pesos, etc.), para determinar cuánto dinero debería recibir cada uno, necesitamos más información sobre cómo se distribuye el trabajo entre ellos.
Si los tres contribuyen de manera equitativa y realizan la misma cantidad de trabajo, podrían dividir el pago de manera igualitaria. En ese caso, cada uno recibiría 100 unidades monetarias (300 dividido entre 3).
Sin embargo, si uno de ellos realiza más trabajo o tiene una mayor responsabilidad en la tarea, podría ser justo que reciba una porción mayor del pago. En ese caso, la distribución de los 300 unidades monetarias dependerá de un acuerdo previo entre ellos sobre cómo se divide el pago en función de la cantidad o calidad del trabajo realizado.
Es importante tener en cuenta que la asignación exacta de dinero puede variar dependiendo de las circunstancias y el acuerdo al que lleguen Verónica, Ana y Luis.

An architect's model for a house is 1.25 ft long and 1.75 ft wide. The actual
house is 60 ft long. What is the width of the house?
The width of the house is 84ft.
What is the width of the house?The first step is to determine the scale of the model. In order to determine the scale of the model, divide the length of the house by by the length of the house in the model.
Scale = length of the house / length of the house in the model
60 / 1.25 = 48 ft
Actual width of the house = scale x width in the model
48 x 1.75 = 84 ft

Jenny measured 1/7 cup of flour and 1/3 cup of flour. How many total cups of flour did Jenny measure?
Answer:
I think it 25/36.
Step-by-step explanation:
The total amount of flour is 4/9 + 1/4. The common denominator of 9 and 4 is 36.
So 4/9 + 1/4 = 16/36 + 9/36 = 25/36
Jenny measured a total of 10/21 cups of flour.
Given that,
Jenny measured 1/7 cup of flour and 1/3 cup of flour. How many total cups of flour did Jenny measure is to be determined.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Fraction is defined as the number of compositions that constitute the Whole. The fraction can be represented in the form of a / b.
Here,
Let, the total measure of the cups of flour be x,
x = 1/7 + 1/3
Taking lcm of the denominator 7, 3 which is 21,
now multiplying the numerators by 3 and 7,
x = (3*1 + 1*7)/21
x = 10 / 21
Thus, Jenny measured a total of 10/21 cups of flour.

Step-by-step explanation:
Enter the trigonometric equation you would use to solve for x. Do not solve the equation.
Answer:
\(x=12\times \text{tan}(20^0)\)
Step-by-step explanation:
From the figure attached,
Measure of an angle = 20°
Measure of the opposite side = x
Measure of the adjacent side = 12
By applying tangent rule in the given right triangle,
tan(20°) = \(\frac{\text{Opposite side}}{\text{Adjacent side}}\)
\(\text{tan}(20^0)=\frac{x}{12}\)
\(x=12\times \text{tan}(20^0)\)
Therefore, equation to get the value of 'x' will be,
\(x=12\times \text{tan}(20^0)\)

domain
range
Answer:
Domain: all real numbers, or (-oo, oo)
Range: (3, oo).
Step-by-step explanation:
The domain is the set of x-values that work when plugged into a function. Here, all values when plugged in produce a real answer, so the answer is all real numbers, or (-oo, oo).
The range is the result of the domain, or the y-values. Since the x^2 will only produce positive numbers, the lowest y-value we can get is 3, and the highest y-value we can get is infinity. So, the answer is (3, oo).

https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:

The proof for r= v²/g tan \(\theta\) is shown below.
What is Trigonometry?Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
Given:
r = v²/g tan (π/2 - \(\theta\))
So, tan (π/2 - \(\theta\)) = sin (π/2 - \(\theta\))/ cos (π/2 - \(\theta\))
Now, using identity
sin (π/2 - \(\theta\))= sinπ/2 cos\(\theta\) + cos π/2 sin\(\theta\)
and, cos (π/2 - \(\theta\)) = cos π/2 cos\(\theta\) + sin π/2 sin\(\theta\)
Also, cos π/2 = 0 and sin π/2 =1
sin (π/2 - \(\theta\)) = cos\(\theta\) and cos (π/2 - \(\theta\))= sin\(\theta\)
Then, tan (π/2 - \(\theta\))
= sin (π/2 - \(\theta\))/ cos (π/2 - \(\theta\))
= cos\(\theta\) / sin\(\theta\)
= 1/ tan \(\theta\)
Now, r = v²/g tan (π/2 - \(\theta\))
r= v²/g x 1/ tan \(\theta\)
r= v²/gtan \(\theta\)

In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
A) statistical significance.
B) correlation.
C) reliability.
D) standard deviation.
Answer:
In distributions in which many scores differ greatly from the distribution’s mean, the bigger the:
D) standard deviation.
Step-by-step explanation:
The more spread out or variable a data distribution is, the greater its standard deviation. A standard deviation is the square root of the variance. A mean is an average of all set of available data. It is obtained by dividing the value of data by the number of the data set. The standard deviation is the statistics that basically measure the distance from the mean, and is calculated as the square root of variance determined by each data point relative to the mean.
Linear sequence of 35/100,5/10,65/100
The linear rule for the sequence is f(n) = 7/20 + 3/20(n - 1)
Finding the linear rule for the sequenceFrom the question, we have the following parameters that can be used in our computation:
35/100,5/10,65/100
In the above sequence, we can see that 15/100 is added to the previous term to get the new term
This means that
First term, a = 35/100
Common difference, d = 15/100
The nth term is then represented as
f(n) = a + (n - 1) * d
Substitute the known values in the above equation, so, we have the following representation
f(n) = 35/100 + 15/100(n - 1)
So, we have
f(n) = 7/20 + 3/20(n - 1)
Hence, the explicit rule is f(n) = 7/20 + 3/20(n - 1)

Hubble's constant H is about 70 km/sec per megaparsec. (The prefix "mega" means million.) Convert this value for Hubble's constant to km/s/million LY. Hint: -A parsec is 3.26 light-years, and therefore a megaparsec is 3.26 million LY. If you take the given value of the Hubble constant (namely, 70 km/s per megaparsec) and replace the megaparsec with 3.26 million LY, then you will have converted to the desired units.
Hubble's constant in units of km/s/million LY is approximately 21.47.
what is approximately ?
Approximately means close to or nearly, but not exactly. It is used to indicate that a value or number is an estimation or approximation, rather than an exact value. It is often used when a precise value is not necessary or when the exact value is unknown or difficult to determine.
In the given question,
To convert Hubble's constant from km/s/Mpc to km/s/million LY, we need to multiply it by a conversion factor that accounts for the difference in distance units. We can use the fact that 1 Mpc is equal to 3.26 million LY:
1 Mpc = 3.26 million LY
Therefore, to convert Hubble's constant from km/s/Mpc to km/s/million LY, we can use the following conversion factor:
1 Mpc / 3.26 million LY
Multiplying Hubble's constant by this conversion factor gives:
H = 70 km/s/Mpc x (1 Mpc / 3.26 million LY) = 21.47 km/s/million LY
Therefore, Hubble's constant in units of km/s/million LY is approximately 21.47.
