Question #1:

Put the markup as a decimal.

80% = 0.8

Multiply.

0.8 * 300 = 240

Add.

300 + 240 = $540

The price of the sofa after markup is $540

Question #2:

Divide.

8 / 90 = 0.0888888

Multiply.

0.0888888 * 100% = 8.88888%

Round.

8.89%

8.89% is the percent of 90 is 8.

Question #3:

Turn percentage into a decimal.

80% = 0.8

Multiply

300 * 80 = 240

80% of 300 is 240

Question #4:

Put the markup as a decimal.

8.01% = 0.0801

Multiply.

2,500 * 0.0801 = $200.25 (markup)

Add.

2,500 + 200.25 = $2,700.25

The price after markup is $2,700.25

Check the picture below.

a circle has a total of 360°, if we split the circle with a hexagon's radii, each radii with their vertices will make an equilateral triangle who will have three 60° angles.  Anyhow, if we run a line like the apothem "a" there, we'll end up with a 30-60-90 triangle, and then we can apply the 30-60-90 rule, as you see there.

since we know then that the distance from a vertex at the base to the center is 2, and the slant-height, sticking out from that vertex, is 6, then we can use the pythagorean theorem as you see in the picture, to get the distance V.

Choose the correct sum of the polynomials (4x3 − 2x − 9) (2x3 5x 3). 6x3 − 3x − 6 2x3 − 7x − 12 6x3 3x − 6 2x3 3x − 3.

The correct sum of the polynomial is \rm 6x^3 + 3x - 6.

We have to determine

The correct sum of the polynomials.

<h3>Sum of the polynomials</h3>

Sum of the polynomials is just a matter of combining like terms, with some order of operations.

Then,

The correct sum of the polynomial is;

\rm (4x^3 - 2x - 9) + (2x^3 + 5x + 3) \\\\ 4x^3 - 2x - 9 + 2x^3 + 5x + 3\\\\ 6x^3 + 3x - 6

Hence, the correct sum of the polynomial is \rm 6x^3 + 3x - 6.
