Then, multiply both sides by −20. First, add n to both sides. Then, subtract 11 from both sides. First, subtract 11 from both sides. Then, multiply both sides by −1. First, add n to both sides. Then, subtract 20 from both sides.

Answers

Answer 1

Answer:

First, subtract 11 from both sides. Then, multiply both sides by −1.

First, add n to both sides. Then, add 20 to both sides.

Step-by-step explanation:

Given equation:

11 - n = -20

Solve for variable n

11 - n = -20

Subtract 11 from both sides

11 - n - 11 = -20 - 11

- n = - 31

Multiply both sides by -1

- n(-1) = - 31(-1)

n = 31

First, subtract 11 from both sides. Then, multiply both sides by −1.

11 - n = -20

11 -n +n = -20 + n

11 = -20 + n

11 + 20 = -20 + n +20

31 = n

First, add n to both sides. Then, add 20 to both sides.

First, subtract n from both sides. Then, multiply both sides by −20.

First, add n to both sides. Then, subtract 11 from both sides.

11 - n = -20

11 - n +n = -20 + n

11 = -20 + n

11 - 11 = -20 + n -11

Not possible

First, subtract 11 from both sides. Then, multiply both sides by −1.

First, add n to both sides. Then, subtract 20 from both sides.

11 - n = -20

11 - n + n = -20 + n

11 = -20 + n

11 - 20 = -20 + n - 20

9 = n - 40

Not possible

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equal to zero. Which expression represents the percent?

Answers

Answer:

[tex]Percent = \frac{100a}{b}\%[/tex]

Step-by-step explanation:

Given

[tex]\frac{a}{b}[/tex]

Required

Convert to fraction

To do this, we simply multiply the fraction by 100%

This gives:

[tex]Percent = \frac{a}{b} * 100\%[/tex]

[tex]Percent = \frac{a * 100}{b}\%[/tex]

[tex]Percent = \frac{100a}{b}\%[/tex]

The expression cannot be further simplified.

Take for instance the fraction is: [tex]\frac{2}{5}[/tex]

Using the same analysis, the percentage would be:

[tex]Percent = \frac{2}{5} * 100\%[/tex]

[tex]Percent = \frac{2 * 100}{5}\%[/tex]

[tex]Percent = \frac{200}{5}\%[/tex]

[tex]Percent = 40\%[/tex]

Answer:

100(a divided by b)

Find the relative frequency;

It is the number of times an event occurs.

Here the time frame is within a day;

  Relative frequency = [tex]\frac{number of cars + number of vans + others}{number of days}[/tex]

An airplane is flying in the direction of 30 degrees South of East at 500 mph. A wind is blowing in the direction of 45 degrees North of East at 55 mph. Find the direction angle of the airplane’s path, adjusted for the wind.

Answers

Answer:

Step-by-step explanation:

The angle of the airplane’s path is = [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ

what is vector?

A vector is defined as a quantity which has two independent properties magnitude and direction.

î & ĵ denote two unit vectors along East & North directions respectively.

V1 denotes velocity vector direction of  airplan of 30 degrees South of East at 500 mph

V2 denotes velocity vector wind the direction of 45 degrees North of East at 55 mph

V denotes the actual velocity vector of the given plane.

Hence from above data we get following descriptions,

V1 = 500.(sin 30°).î + 450.(cos 30°).ĵ

= 500.(1/2).î + 500(√3/2.ĵ

= 250î + 250√3ĵ

V2 = 55(sin 45°).î - 55(cos 45°).ĵ

= 55[1/√2].î - 55[1/√2]ĵ

V = V1 + V2

= 250î + 250√3ĵ +55[1/√2].î - 55[1/√2]ĵ

= 250î +55[1/√2].î + 250√3ĵ - 55[1/√2]ĵ

= [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ

Hence the angle of the airplane’s path is = [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ

Answer:

Parallel line - y=6x+9

Perpendicular line - y=-1/6x +4

Step-by-step explanation:

Parallel lines have a slope that is equal to the origninal equation. You use the y-y1=m(x-x1) equation. In this case, your y1 is 3 and your x1 is -1. Plug these into the equation along with your slope of 6.

y-y1=m(x-x1)

y-3=6(x-(-1))

y-3=6(x+1)

y-3=6x+6 - Distribute

+3 +3 - Add 3 to both sides

y=6x+9

For perpendicular lines, the slope is the negative reciprocal of the given slope. In this case, the slope is -1/6. Your y1 is 4 and your x1 is 0.

y-y1=m(x-x1)

[tex]y - 4 = - \frac{1}{6} (x - 0)[/tex]

Distribute:

[tex]y - 4 = - \frac{1}{6} x[/tex]

+4 +4

Add 4 to both sides:

[tex]y = - \frac{1}{6} x + 4[/tex]
