A sweater is 15% off. The regular price is $24. What is the price after the discount is taken off?

Answers

Answer:

$20.40 after the discount

Step-by-step explanation:

To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6

Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40

3.60 cent because when you multiply 0.15 by 24$ you get 3.6 .

Alright,Alex let say we have factored a quadratic into two binomial, for example

[tex](5x + 3)(6x - 4)[/tex]

If we set both of those equal to zero

[tex](5x + 3)(6x + 4) = 0[/tex]

We can used the zero product property in this case to find the roots of the quadratic equation.

This means that

[tex]if \: ab = 0 \: then \: a = 0 \: and \: b = 0[/tex]

This means we set each binomal equal to zero to find it root.

[tex]5x + 3 = 0[/tex]

[tex]5x = - 3[/tex]

[tex]x = - \frac{3}{5} [/tex]

[tex]6x + 4 = 0[/tex]

[tex]6x = - 4[/tex]

[tex]x = - \frac{2}{3} [/tex]

So our roots are negative 3/5 and negative 2/3 using zero product property

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.

What expression represents the profit, and what is the profit if 240 cell phones are sold?

40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800

Answers

Answer:

Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.

Step-by-step explanation:

The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850

How to calculate profit

Revenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40

where,

x = number of cell phones sold.

Profit = Revenue - cost

= (2x² + 55x + 10) - (2x² – 15x – 40)

= 2x² + 55x + 10 - 2x² + 15x + 40

Profit = 70x + 50

If x = 240

Profit = 70x + 50

= 70(240) + 50

= 16,800 + 50

= $16,850

  (x, y) ⇒ (x -5, y +3)

Step-by-step explanation:

Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.

Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.

Here, that addition is 5 squares left and 3 squares up:

  image - original = (-4, 3) -(1, 0) = (-5, 0)

So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:

   (x, y) ⇒ (x -5, y +3)

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain

Answers

Answer:

No, it is not a right triangle.

Step-by-step explanation:

Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.

If triangle is a right triangle we can use Pythagorean theorem, c^2=a^2+b^2
c=15, a=5, b=10
15^2=5^2+10^2
225=25+100
225=125
225 is not equal to 125 therefore, this triangle is not a right triangle.
