Answer:

$810 in commission

Step-by-step explanation:

1. Make a proportion. Method: Percent proportion

$\frac{percent}{100} = \frac{part}{whole}$

2. your proportion should look like this. Note: we don't know how much commission he earned.

$\frac{9}{100} =\frac{x}{9000}$

3. cross-multiply. Multiply 9 x 9000 and make 100x because we don't know its value yet. Hint: X is our unknown commission.

$9000$ × $9$ = $81000$

4. set your new proportion.

$\frac{100x}$ $=$ $\frac{81000}$

5. divide the proportion by 100 on each side.

$\frac{100x}{100} = \frac{81000}{100}$

6. After dividing your proportion.

$Answer$ $=$ $ $810$ $in$ $commission$

What is the ratio 14/15 expressed in simplest form? <br><br><br><br> PLZZ HELP!

agasfer [191]

14 and 15 have no common factor except ' 1 ' ,
so the fraction 14/15 can't be simplified.

It's already in the simplest available form ("lowest terms").

There are nine possible combinations as follows: bb, bc, bt, cb, cc, ct, tb, tc, tt, each having a probability of 1/9. The four combinations with a cab exactly one time are: bc, cb, ct, tc. Therefore the probability that she'll use a cab exactly one time is: 4/9.

From the second:

x=(4+y)/2 and applying this to first:

y=2 and since x=(4+y)/2, x=3 so

Solving Quadratic Equations with Complex SolutionsThe discriminant: D=b^2-4acQuestion:5x^2-2x+1=0

fomenos

• The value of the discriminant ,D= -16

,

• The solution to the quadratic equation is

$x=\frac{1+2i}{5}\text{ or }\frac{1-2i}{5}$

Step - by - Step Explanation

What to find?

• The discriminant d= b² - 4ac

,

• The solution to the quadratic equation.

Given:

5x² - 2x + 1=0

Comparing the given equation with the general form of the quadratic equation ax² + bx + c=0

a=5 b=-2 and c=1

Uisng the quadratic formula to solve;

$x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}$

The discriminant D=b² - 4ac

Substitute the values into the discriminant formula and simplify.

D = (-2)² - 4(5)(1)

D = 4 - 20

D = -16

We can now proceed to find the solution of the quadratic equation by substituting into the quadratic formula;

$x=\frac{-(-2)\pm\sqrt[]{-16}}{2(5)}$

Note that:

√-1 = i

$x=\frac{2\pm\sqrt[]{16\times-1}}{10}$

$x=\frac{2\pm\sqrt[]{16}\times\sqrt[]{-1}}{10}$ $x=\frac{2\pm4i}{10}$ $x=\frac{2}{10}\pm\frac{4i}{10}$ $x=\frac{1}{5}\pm\frac{2}{5}i$ $x=\frac{1\pm2i}{5}$

That is;

$\text{Either x=}\frac{1+2i}{5}\text{ or x=}\frac{1-2i}{5}$
