For the sale of a $ 10 item with a discount of 30 % has a <em>sales</em> tax of $ 0.35.

<h3>How much money should we pay in sales tax?</h3>

In this question we must determine the amount of money needed to pay in taxes by the purchase of an item with a discount. <em>Sales</em> taxes are an example of <em>indirect</em> taxes, this kind of <em>indirect</em> tax is usually calculated on the basis of <em>total</em> costs, including discounts. The amount of money need for the sales tax is described below:

t = (r / 100) · (1 - d / 100) · c     (1)

Where:

  • d - Discount rate
  • r - Sales tax rate
  • c - Item price
  • t - Sales tax total

If we know that d = 30, r = 5 and c = 10, then the sales tax total is:

t = (5/ 100) · (1 - 30 / 100) · 10

t = 0.35

For the sale of a $ 10 item with a discount of 30 % has a <em>sales</em> tax of $ 0.35.

Solve for the value of x in the picture above​
aksik [14]

Answer: 40

Step-by-step explanation:

Since this is a scalene, we know there are two 70 degree angles. Because triangles are 180 degrees, and 70 + 70 = 140, 180 - 140 = 40.

Hope this helps,

Use the quadratic polynomial 12x2+5x−2 to answer the questions.
Advocard [28]

Answer:

A: This polynomial has a degree of 2 , so the equation 12x2+5x−2=0 has two or fewer roots.

B: The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots.

Step-by-step explanation:

f(x) = 12x^2 + 5x - 2.

Since this is a quadratic equation, or a polynomial of second degree, one can easily conclude that this equation will have at most 2 roots. At most 2 roots mean that the function can have either 2 roots at maximum or less than 2 roots. Therefore, in the A category, 2nd option is the correct answer (This polynomial has a degree of 2 , so the equation 12x^2 + 5x − 2 = 0 has two or fewer roots).

To find the roots of f(x), set f(x) = 0. Therefore:

12x^2 + 5x - 2 = 0. Solving the question using the mid term breaking method shows that 12*2=24. The factors of 24 whose difference is 5 are 8 and 3. Therefore:

12x^2 + 8x - 3x - 2 = 0.

4x(3x + 2) -1(3x+2) = 0.

(4x-1)(3x+2) = 0.

4x-1 = 0 or 3x+2 = 0.

x = 1/4 or x = -2/3.

It can be seen that f(x) has two distinct real roots. Therefore, in the B category, 1st Option is the correct answer (The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots)!!!

What is the perimeter???
vekshin1

Answer:

90 cm

Step-by-step explanation:

The top and the bottom are the same length, 45 cm

The horizontal piece at the bottom is 45-25 = 20 cm

The left and the right are the same length 30cm

The vertical piece at the bottom is 30 -22 =8 cm

Starting at the bottom left corner and going clockwise, we add up all the sides to find the perimeter

22 +45+30+20+8+25

150

The perimeter is 150 cm
