WILL GIVE BRAINLIEST!HURRY! At the end of practice, there are 240 ounces of sports drink left in the cooler. Every player had some sports drink from the cooler. Based on the equation, y= 648 - 24x, how many players were at practice?

Answers

Answer:

Hello!

The answers are:

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. Each plater drinks approximately 24 ounces of sports drink at practice.

E. For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice.

Why?

We are given the equation:

Let's discard each of the given options in order to find the three correct options.

A. The cooler is meant to be used only by 24 players: False.

If we want to calculate how many players can use the cooler, we need to isolate "x" (rate of change) from the given equation, so, isolating we have:

We have that the cooler can be used by 27 players, so, the first option that states that "The cooler is meant to be used only by 24 players" is false.

B. Before practice, there are 648 ounces of sports drink in the cooler: True.

We have that before the practice when the cooler is not being used by any player (or there is no any player) has 648 ounces (full), we can calculate it making the variable "x" equal to 0, so, calculating we have:

Therefore, we have that the statement "Before practice, there are 648 ounces of sports drink in the cooler." is true.

C. Each plater drinks approximately 24 ounces of sports drink at practice: True.

From the statement, we know that the rate of change is equal to (-24), and it's equal to the number of ounces that each player drinks.

Hence, we have that the statement  "Each plater drinks approximately 24 ounces of sports drink at practice." is true.

D. If  24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink: False.

If we want to calculate the number of ounces that 24 players will drink, we need to use the slope value. If we know that each player drinks 24 ounces, so, to calculate how many ounces of sports drink will 24 players drink, we need to use the following equation:

We have that 24 players will drink a total of 576 ounces, so, the statement "If  24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink." is false.

E. For each additional player that takes a drink, there will be approximately 24 fewer ounces of sporks drink remaining after the practice: True.

From the statement and the equation, we know that the slope (rate of change) is negative, meaning that for each player (x) it will be 24 fewer ounces of sports drink after practice, for example, calculating for 1 and 2 players, we have:

We can see that for each player, it will be 24 fewer ounces of sports drink after practice.

Hence, we have that the statement "For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice." is true.

Therefore, the correct options are:

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. Each plater drinks approximately 24 ounces of sports drink at practice.

E. For each additional player that takes a drink, there will be approximately  24 fewer ounces of sporks drink remaining after the practice.

Answers

C(-4,-5), A(3,1), T(-2,7). X values of the coordinates remain the same while Y values change their signs. This is because the point will not move vertically when reflecting over the Y-axis, but it will have the same horizontal distance from the y-axis in the opposite direction.

find the distance between Union and Santa Cruz if they are 3cm apart on a map this a scale of 1cm: 13km.

Answers

With the scale being 1cm: 13km your answer will be 39. This scale means that every cm equals 13km. Since they are 3 cm apart on the map, you do 3•13 to find how far they are truly. (3•13=39)

Answer:

The answer to your problem is, 39 kilometers

Step-by-step explanation:

We know that 1 centimeters on a map is 13 kilometers based on what the question is saying.

So we need to multiply 13 x 3 since in the question it quotes " 3 cm apart on a map . . . "

So lets do some multiplying:

13 x 3 =

3 x 10 = 30.

3 x 3 = 9.

30 + 9 = 39.

Thus the answer to your problem is, 39 kilometers

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) ___.


If (−6,4) satisfies the equations of two lines, (−6,4) is ___ , so the lines will ___ at (−6,4).

This means that if two lines ____ at (−6,4), then (−6,4) is the ____ to the system of equations.

This means that if you substitute −6 for x and 4 for y in the equations, both equations will be ____.

Answers

Answer:

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.

This means that if you substitute −6 for x and 4 for y in the equations, both equations will be true. However, this information alone is not enough to determine whether a system of linear equations has a solution just by looking at the graph of the equations

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

The coordinates of (−6,4) satisfy the equation y=13x + 6 because (−6,4) makes the equation true.

If (−6,4) satisfies the equations of two lines, (−6,4) is a point on both lines, so the lines will intersect at (−6,4).

This means that if two lines intersect at (−6,4), then (−6,4) is the solution to the system of equations.

What is 5/6 of 14 1/2?

PLEASE explain how it is!

please help its last question and i been on it for 15 minutes

Answers

Answer:

5/6 of 14 1/2 is 12.08333333

Step-by-step explanation:

14 1/2 = 14.5

14 = 14

and 1/2 = 0.5

now, you take 14.5 and divide by the denominator of the fraction that you have, which is 6

14.5 ÷ 6 = 2.416666667

and now you take 2.416666667 and multiply that by 5, because you are trying to find 5/6 of this number

2.416666667 × 5 = 12.08333333

So your answer is 12.08333333

It’s 12 1/12.
You basically just multiply 5/6 and 14 1/2 which is 145/12 and that simplified is 12 1/12

Answers

From my understanding and your lack of a picture:

The triangle CAT has rotated in 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of the vertices of the pre-image are C(-2,1), A(-3,3) and T(1,1). The coordinates of the vertices of the image are C'(1,2), A'(3,3) and T(1,-1).

From these coordinates, we can conclude that the relation between the preimage and image is

If a figure rotated 90 degrees clockwise direction about the origin, then

Therefore triangle CAT is rotated 90 degrees clockwise direction about the origin or 270 degrees counterclockwise direction about the origin.

Answers

Answer:

x 6

Step-by-step explanation:

Simplify The Equation,

[tex] \frac{(x + 6)}{x {}^{2} - 36} + \frac{1}{x - 6} \\ = \frac{(x + 6)}{ ({x})^{2} -(6)^{2} } + \frac{1}{x - 6} \\ = \frac{(x + 6)}{(x + 6)(x - 6)} + \frac{1}{x - 6} \\ = \frac{(x + 6) + 1(x + 6)}{(x + 6)(x - 6)} \\ = \frac{x + 6 + 1x + 6}{(x +6)(x - 6)} \\ = \frac{2x + 12}{(x + 6)(x - 6)} [/tex]

Factorize The Equation,

[tex] \frac{2x + 12}{(x + 6)(x - 6)} \\ = \frac{2(x + 6)}{(x + 6)(x - 6)} \\ = \frac{2}{x - 6} [/tex]

From the Given function,

x-6 ≠ 0

x ≠ 6

Thus x ≠ 6 is a restriction.

The solution is : x ≠ 6, is a restriction on the variables

(x+6)/x^2-36 + 1/x-6.

What is  simplification?

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

Simplify The Equation,

(x+6)/x^2-36 + 1/x-6

=(x+6)/(x-6) (x+6) + 1/x-6

= (x+6)+(x+6) /(x-6) (x+6)

=(2x+12)/(x-6) (x+6)

Factorize The Equation,

(2x+12)/(x-6) (x+6)

= 2(x+6) /(x-6) (x+6)

=2/ (x-6)

From the Given function,

x-6 ≠ 0
