Stella is going to a carnival that has games and rides. Each game costs $2.50 and each ride costs $4. Stella spent $52.50 altogether at the carnival and the number of rides she went on is twice the number of games she played. Write a system of equations that could be used to determine the number of games Stella played and the number of rides Stella went on. Define the variables that you use to write the system.

The number of tacos that you can get if a drink cost $1.50 and each taco cost $.75 is 4.67.

5 = 1.50 + 0.75t

5 - 1.50 = 0.75t

3.50 = 0.75t

t = 3.50 / 0.75

t = 4.666666666666666

Approximately,

t = 4.67

Therefore, the number of tacos that you can get if a drink cost $1.50 and each taco cost $.75 is 4.67

Answer:

See explanation

Step-by-step explanation:

f(x)=|x|

f(x) ==> f(x+3): translation of function 3 units to the left, f(x-3) would be translation 3 units right

f(x+3) ==> 3f(x+3): vertical stretch by a factor of 3

f(x+3) ==> -3f(x+3): Reflection over the x-axis, since y value changes over the x-axis while x value changes over the y-axis

-3f(x+3) ==> h(x)=-3f(x+3)+1: Translation one unit up.

The translation of a coin from A to C using a translation vector is ;

Vector AC = (7, 3).

A translation in arithmetic a structure left or right and/or up or down. The translated shapes appear to be of the same size as the initial structure, indicating that the shapes are congruent.

Now, as per the given question.

See the given figure.

The coordinates if the points A and C are.

A = (-3, -1) and C = (4, 2)

The translation from A to C is estimated as;

AC = (4 + 3) ,(2 + 1)

Translation AC = (7, 3)

Thus,  the given point A shifts 7 units to its right and then 3 units up to the point C.

Therefore, the representation of the translation of A and C in the form of

The original coordinates of flea were  (  5 , - 3) .

What does coordinate mean in this case?

F' = ( 4 , - 1 )

To undo translation of 9 units’ right and 4 units down, translate 9 units left and 4 units up

Reflect back across Y-axis to undo reflection means change x -coordinate by -1

(- 5,3)    →    ( 5, 3)

Reflect back across x-axis to undo reflection means change y-coordinate by -1

First of all, you refer to physics. Physicists detest miles per second estimate units. They would use meters per second (SI units),centimeters per second (CGS or less desirable SI units), or the value 1 (so-called natural units) be dependent on the type of work they are doing experimental.

Second, suppose you are mention to the condition of a vacuum. Light slows down when passing through the other a vacuum.

Third, even if physicists use miles per second as units, the values you gave are quite discrepant. The value 299 792 458 m/s is one of the  values of the international system of units (SI). The speed of light is not explained to be this value, but it is a fixed value regarded as exact to be used in explain what is a meter . If in any case, it is not a calculate value and it has no uncertainty. If we do an exact conversion of this exactly value to miles per second, which is 186282 (39937/100584) m/s .

We see that, the meter per second value you stated is require, the mile per second value is only a rounded approximation and is off by about 0.15 %.

The 299 792 458 m/s value is what physicists use when they are doing calculations as part of their research, because they require the exactness. they will round off to one significant digit (actually the value is correct to three significant digits but it looks like just one) and use 300 000 000 m/s = 3 × 10⁸ m/s, which is almost trivial to multiply or divide by mentally (unlike the 186 000 mi/s) and is only 0.07 % off.

The value of 184 is 21th term value.

The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.

The formula of Arithmetic progression is

a(n) = a1 + (n - 1)d

given that the terms of arithmetic sequence,

a2 = 4 and d = 9.

now find the which term is 184.

a(n) = a1 + (n - 1)d

now, substitute a(n) = 184, d = 9.

184 = 4 + (n - 1)9

184 = 4 + 9n -9

184 = -5 +9n

184 + 5 = 9n

The screen size of the HDTV is approximately 36.65 inches.

Here,

The screen aspect ratio of a high-definition television is 16:9, which means the width is 16 units and the height is 9 units.

We are given that the width of the HDTV is 41 inches.

To find the screen size, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the diagonal distance across the screen) is equal to the sum of the squares of the other two sides (width and height).

Let's assume the height is h inches.

Using the Pythagorean theorem, we have:

[tex](41^2) = (16^2) + (9^2) + (h^2)[/tex]

Simplifying this equation, we get:

[tex]1681 = 256 + 81 + h^2\\1681 = 337 + h^2\\h^2 = 1681 - 337\\h^2 = 1344\\[/tex]

Taking the square root of both sides, we find:

h ≈ 36.65 inches

The equation that could be used to determine c, the cost of labor per hour is $603.75= x × 5.25 and cost of labour per hour is $115

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

The total amount paid by Andres is the sum of the total cost of labour and the cost of the parts.

The Total amount paid = total cost of labour + cost of parts

$719.75= total cost of labour + $116

The total cost of labour = $719.75- $116

= $603.75

The total cost of labour = cost of labour per hour x total time worked

$603.75= x × 5.25

xx = $603.75/ 5.25

xx = $115

A factor exists a number that completely divides another number.

The factor of x²y³ - 11x²y + 6y² - 66 is (x²y + 6)(y² - 11).

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we exists adding are factors of the product because the product exists divisible by them.

By eliminating the common variables, one may get the components of the equation x²y³ - 11x²y + 6y² - 66.

x²y³ - 11x²y + 6y² - 66

Take out the common from the first two terms.

⇒ x²y(y² - 11) ..........(1)

Take out common in the last two terms.

⇒ 6 (y² - 11) ..........(2)

Adding both the equations, (1) and (2) then

[x²y(y² - 11)] + [6 (y² - 11)] = x²y(y² - 11) + 6(y² - 11)

simplifying the above equation, we get

⇒ (x²y + 6)(y² - 11)
