Step-by-step explanation:

A school is planning a fundraiser with all profits going to charity. The amount of profit is found by subtracting the total cost from total ticket sales.
Ticket Sales: 200x−10x2

Event Cost: 500+20x

If x represents the price of a ticket, what ticket prices will result in a profit of $200 or more? Express your answers rounded to the nearest cent.



A
$5.69≤x

B
$5.69≤x≤$12.33

C
$3.29≤x

D
$3.29≤x≤$21.29

Please help.

Answers

The value of the x should be more than or equal to 5.69. Then the correct option is A.

What is inequality?

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.

A school is planning a fundraiser with all profits going to charity.

Ticket Sales: 200x − 10x²

Event Cost: 500 + 20x

The amount of profit is found by subtracting the total cost from total ticket sales. A profit of $200 or more.

             Event cost − Total sales  ≥ Profit

         (500 + 20x) − (200x − 10x²) ≥ 200

− 200x + 10x² + 500 + 20x − 200 ≥ 0

                         10x² + 180x − 700 ≥ 0

                         10x² − 180x + 700 ≥ 0

                                  x² − 18x + 70 ≥ 0

On simplifying, we have

(x − 5.69) (x − 12.33) ≥ 0

                               x ≥ 5.69, 12.33

Thus, the value of the x should be more than or equal to 5.69. Then the correct option is A.

Equivalent or Not?
Sarah thinks that the following
expressions are equivalent:
2x + 3 = x/2 + 4
Is she correct? If so, prove that these
two expressions are equivalent. If not,
explain what errors she made.

Answers

Answer:

equivalent

Step-by-step explanation:

2x + 3 = x/2 + 4

2x - x/2 = 4 - 3

3x/2 = 1

x = 1 (2) / 3

x = 2/3

substitute the value of x=2/3 back into the equation:

2(2/3) + 3 = (2/3)/2 + 4

4/3 + 3 = 1/3 + 4

13/3 = 13/3  both are equal if x=2/3

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)

Answers

Answer:

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (40-0)/(10-0)

   = 40/10

   =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

Step-by-step explanation:

Answers

I think it’s (-2, -16)

If u substitute the y into the second equation it gives you 8x=2x-12 then, you subtract 2x from both sides and it gets you 6x=-12 lastly, you divide by 6 which gets you x=-2. To find y you can take the first equation and plug x in which gives you y=8(-2) and then you multiply which gives you y=-16!! I really hope this helped!!

Step-by-step explanation:

Hey there!

Given;

The equations are;

y = 8x...........(i)

y = 2x-12..........(ii)

Now;

Substituting the value of "y" from equation (i).

8x = 2x-12

8x-2x = -12

6x = -12

X = -12/6

Therefore, X= -2.

Now; Substituting the value of "y" in equation (i)

y = 8*-2

y = -16

Therefore, y= -16.

Therefore, x= -2 and y= -16.

Check:

y = 2x

-16= 8*-2

-16 = -16 (true).

Describe a sequence of transformations that take isosceles trapezoid T to its image T'

Answers

Answer:If you rotate trapezoid BEFG counter clockwise 90° then reflected across pointy you will have the image above

Step-by-step explanation:

Transformation involves changing the position of a shape

The transformation from T to T' is a 90 degree counterclockwise

From the figure, we can see that:

The angle between isosceles trapezoid T and its image T' is a right-angle (i.e. 90 degrees)Figure T' is at the right of T

This means that:

A 90 degree counterclockwise through point D will take trapezoid T to T'

Hence, the required transformation is a 90 degree counterclockwise through point D

A civil engineer wants to know the opinions of drivers about online driving tests. She obtains a list of 730 drivers who have recently completed an online driving course and e-mails a questionnaire to a randomly selected group of 200 of these drivers. Only 102 of the questionnaires are returned. Identify the population and the sample in this study. (4 points)

The population is 200 and the sample is 102.
The population is 730 and the sample is 200.
The population is 102 and the sample is 730.
The population is 730 and the sample is 102.
The population is 200 and the sample is 730.

Answers

Answer: The population is 730 and the sample is 102.

Step-by-step explanation:

When we have a given set of elements, N elements, the population is N.

And if we do statistics with A of these N elements, the sample is A.

In this case, the population is the set of the 730 drivers, then the population is 730.

And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).

Then the sample will be 102.

Then the correct option is:

The population is 730 and the sample is 102.

Jim drove 756 miles in 12 hours.
At the same rate, how many miles would he drive in 7 hours?

Answers

Answer:

441

Use a proportion.

756 miles is to 12 hours as x miles is to 7 hours

756/12 = x/7

12x = 7 * 756

12x = 5292

x = 441

Answer: 441 miles

Answer:

441

Step-by-step explanation:

756 divided by 12 = 63

Jim drives 63 miles in 1 hour

Multiply 63 by 7

63 ⋅ 7 = 441

Jim will drive 441 miles in 7 hours
