it is a 5% sales tax

Step-by-step explanation:

12/240= 0.05

0.05 x 100 = 5%

Honestly I would do 240x10% and see what that gives you and if it’s lower than 12 keep raising or lowering the percentage that you’re multiplying by to figure it out yes it takes times. But the answer is 5%.

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). What is m+n?

Answers

Answer:

the aswer is 32

Step-by-step explanation:

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.

To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's begin by dividing the entire equation by 3 to simplify it:

y = (2/3)x^2 - (16/3)x + 6

Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:

y = (2/3)(x^2 - (8/3)x) + 6

Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:

(8/3) / 2 = 4/3

(4/3)^2 = 16/9

Now, we add and subtract 16/9 inside the parentheses:

y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6

Now, we group the first three terms and factor the perfect square trinomial:

y = (2/3)((x - 4/3)^2 - 16/9) + 6

Next, distribute the (2/3):

y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6

Now, simplify:

y = (2/3)(x - 4/3)^2 - (32/27) + 6

Finally, bring everything together:

y = (2/3)(x - 4/3)^2 + (142/27)

Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).

To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):

m + n = 4/3 + 142/27

To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:

4/3 = (4/3) * (9/9) = 36/27

Now we can add the fractions:

m + n = 36/27 + 142/27

m + n = (36 + 142)/27

m + n = 178/27

You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect $1450. How many of each type of ticket did you sell?

Answers

Answer:

5 stars? Answer down below

Step-by-step explanation:

a+b=350 => a=350 - b

3a + 5b = 1450

3(350-b)+b=1450

1050-3b+5b=1450

2b=400

b=200

a=150

There are 200 student ticket and 150 general admission ticket sold.

What is selling price?

The selling price is used to sell the item at a certain cost and can be calculated using the selling price formula. The amount that the buyer pays to buy the product is called the selling price.

Here,

We sold some number, x, of $5 tickets and some number, y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.

So,

$3y + $5x = $1450

and x + y = 350

Solve system of equations.

3(350-x) + 5x = 1450

1050 -3x + 5x = 1450

2x = 400

x=200

y + 200 = 350

y=150

Thus, there are 200 student ticket and 150 general admission ticket sold.
