Percent is parts out of 100 so x%=x/100
38%=38/100=0.38
'of' means multiply 2,000,000 times 0.38=760000

2,000,000/100= 20,000
20,000*38=760,000
tbh i just think its easier this way.

Bob neff, owner of an automotive dealership, pays one of his salesmen, mike, a $1,300 salary per week plus 6% on all commission

AlekseyPX

4 * 500 = $2,000

Then, you must calculate how much he earned by the commission: 

$42,000 * 3% 

(3% = 3/100) 

42,000 * 3/100 = 420 * 3 = $1260 

Finally, you add what he earned form the commission plus the 4 weeks salary: 

$2,000 + $1260 = $3,260

What is the slope of a line that is perpendicular to the line y = 2x – 6?

Zolol [24]

Answer:

The slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

$m$ is the slope

$b$ is the y-intercept

Step 1:

Finding the slope of the given equation

The given equation is

$y = 2x - 6$

comparing with the slope-intercept form of the line equation

The slope of the equation is: m = 2

Step 2:

Determining the slope of the perpendicular line

In Mathematics, a line perpendicular to another line has a slope that is the negative reciprocal of the slope of the other line.

As the slope of the equation is: m = 2

Therefore, the slope of the new perpendicular line:

$-\frac{1}{m}=-\frac{1}{2}$

Hence, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Important Tip:

The product of the slopes of perpendicular lines is -1.

Verification:

The slope of the given line:

$m_1=2$

The slope of the perpendicular line:

$m_2=-\frac{1}{2}\:\:\:\:$

The product of the slopes is:

$\:m_1\times \:m_2\:=2\times -\frac{1}{2}\:\:=-1$

As the product of the slopes of perpendicular lines is -1, therefore, the lines are perpendicular.

Thus, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

What did this person do wrong? Honestly really stuck and do not remember geometry!

dmitriy555 [2]

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

$\dfrac{AB}{AC} = \dfrac{AC}{AD}$

$\dfrac{AB}{x} = \dfrac{x}{AD}$

$\dfrac{25}{x} = \dfrac{x}{16}$

$x^2 = 25 \times 16$

$x = 20$

AC = 20 cm

$\dfrac{AB}{CB} = \dfrac{CB}{DB}$

$\dfrac{AB}{y} = \dfrac{y}{DB}$

$\dfrac{25}{y} = \dfrac{y}{9}$

$y^2 = 25 \times 9$

$y = 15$

CB = 15 cm

A certain triangle has two 45° angles, what thoe of triangle is it?

olganol [36]

Add the two known angles: 45° + 45° = 90°

Now we know the third angles. Which is a 90 degree angle. If a triangle has a 90 degree angle, then it is a right angle triangle.
