If the price of a textbook is $40 before tax is added on, and tax is 10%, what will the final price of the textbook be?

Mathematics
1 answer:
Digiron [165]3 years ago
4 0

Answer:

soln,

price of textbook = $40

tax% = 10%

now,

tax amount = 10% of $40

= 10\100*40

= 10*4/10

= 40/10

= $4.

again,

final price = cost of textbook+tax

=$40+$4

=$44.

Step-by-step explanation:

so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .

Match each algebraic expression with the method to use for factoring.
LekaFEV [45]

Answer:

  • Prime: 3
  • GCF: 1
  • Factoring Trinomials: 4
  • Difference of Squares: 2
  • Perfect Square Trinomial (PST): 5

Step-by-step explanation:

1. Each term has an even coefficient, so a factor of 2 can be removed:

  2(3x^2 +7x -15)

The remaining quadratic factor is prime.

__

2. Each of these two terms is a square, so this is the difference of two squares.

__

3. This cubic has one irrational negative real root. It is prime.

__

4. This trinomial factors in the usual way: (x +15)(x -2). It is factored by "factoring trinomials."

__

5. The magnitude of the x-coefficient is double the square root of the (positive) constant, so this is a perfect square trinomial.

Hassam plotted Point M in the coordinate plane below​
ki77a [65]

Answer:

The answer to your question is the second option, both coordinates should be negative.

Step-by-step explanation:

The point Hassam plotted was (-0.5, -0.25). If he wanted to plot point (0.5, 0.25):

-First, he should have counted two squares to the right

- then one square up.

Because both coordinates are positive this point must be in the first quadrangle not in the third.

Add the following polynomials (write answers in descending order):
kiruha [24]

Answer/Step-by-step explanation:

1. (7j³ - 2) + (5j³ - j - 3)

Open the parentheses

7j³ - 2 + 5j³ - j - 3

Collect like terms. Like terms are terms that have the same degree.

7j³ + 5j³ - j - 2 - 3 (7j³ and 5j³, have the same degree, 2 and 3 are if the same degree)

12j³ - j - 5 (this already in descending order)

2. (8a⁵ - 4) + (3a⁵ + a - 2)

Open parentheses

8a⁵ - 4 + 3a⁵ + a - 2

Collect like terms

8a⁵ + 3a⁵ + a - 4 - 2

12a⁵ + a - 6 (in ascending order from largest to smallest degree)

3. (6m² + 1) + (3a⁵ + a - 2)

6m² + 1 + 3a⁵ + a - 2

Collect like terms

6m² + 3a⁵ + a + 1 - 2

6m² + 3a⁵ + a - 1

Rearrange from largest to smallest degree

3a⁵ + 6m² + a - 1

4. (3m⁵ + 1) + (9m⁵ + 3m - 2)

3m⁵ + 1 + 9m⁵ + 3m - 2

Collect like terms

3m⁵ + 9m⁵ + 3m + 1 - 2

12m⁵ + 3m - 1

5. (- 5x² - x + 4) + (- 3x² - 5x + 2)

Open parentheses

-5x² - x + 4 - 3x² - 5x + 2

Collect like terms

-5x² - 3x² - x - 5x + 4 + 2

-8x² - 6x + 6
