Answer:

Step-by-step explanation:

In mathematics, the discount is a type of reduction in the cost price of a product. Generally, the discount refers to the condition where the selling price of the product is less than the cost price of the product. The discount can be calculated by taking the difference between the cost price and the selling price. Thus, the formula to determine the discount is given as:

Discount = Cost price – Selling Price

Convert 45° from degrees to radians.

leonid [27]

<h2>pi divided by four</h2>

Step-by-step explanation:

Let the angle in degrees be $a$

Let the angle in radians be $r$

If $a$ is the angle in degrees and $r$ is the angle in radians,

$a\times \frac{\pi }{180}=r$

It is given that the $a=45$

$r=\frac{\pi}{180}\times a= \frac{\pi}{180}\times 45=\frac{\pi}{4}$

So, $r=\frac{\pi}{4}$

Zina solves a system of linear equations by elimination and finds a solution of (2, 2). One of the equations is a + b = 4. What

kiruha [24]

The answer is -a + b = 0

If she wants to solve <span>a system of linear equations by elimination and if one equation is unknown, one of the solutions in the unknown equation must be negative:
Known equation: a + b = 4
Unknown equation: -a + b = ?

We know that a = 2 and be = 2, thus:
</span>Unknown equation: -2 + 2 = 0
The general form of the equation is -a + b = 0

Let's check it out:
Known equation: a + b = 4
Unknown equation: -a + b = 0
________________________
Add them up: 2b = 4
b = 4/2 = 2

a + b = 4
a = 4 - b
a = 4 - 2
a = 2

So, the second equation is correct.

Find a function whose graph is a parabola with vertex (7, 8) and that passes through the point. (6, −9).

lukranit [14]

Work backwards from vertex form. Vertex form of a quadratic equation/parabola is the following:

f(x) = a(x - h)² + k, where (h, k) is the vertex.

f(x) = a(x - 6)² - 9

Now, plug in the point that you're given to SOLVE FOR A. Remember that f(x) is just another way of writing y.

8 = a(1)² - 9
8 = a - 9
a = 17

So, plug in a = 17 into the equation.

<span>f(x) = 17(x - 6)² - 9 ←← your answer.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

For the school play, the advance tickets cost $3, while tickets at the door cost $5. Thirty more tickets were sold at door in ad

Talja [164]

Answer:

<u>310</u> tickets were sold in advance before school pay and <u>340</u> door tickets were sold in advance.

Step-by-step explanation:

Given:

Let number of tickets sold in advance be 'x'.

Cost of advance ticket = $3

Cost of door tickets = $5

Also given:

Thirty more tickets were sold at door in advance

Hence number of door tickets sold = $x+30$

Total Money Collected = $2630

Now we can say that Total Money Collected is equal to sum of number of tickets sold in advance multiplied by Cost of advance ticket and number of door tickets sold multiplied by Cost of door tickets.

Framing in equation form we get;

$3x+(x+30)5=2630$
