PLEASE HELP

Answer:

86°

Step-by-step explanation:

- Angles on a straight line add up to 180° always

180° - 94° = x° = 86°

180-94=86

have a good day :)

Radius= 12÷2 => 6 cm

diameter= 12 cm

circumference = 2πr

=> 2× 22/7 × radius

=> 37.7 cm

Hope it helps ^^

Answer:

4/3

Step-by-step explanation:

If Triangle ABC is isosceles with AB = AC is:  13.45 cm.

∆ABC = 85 cm² .

(1/2) ×AC×AB ×sinA = 85 cm²

AC=AB=x

Hence:

85= (1/2)x²×sin110°

A² × sin 110° = 170

A² ×0.94 = 170

A² = 170/0.94

A² =√ 180.85

A= 13.45 cm

Therefore if Triangle ABC is isosceles with AB = AC is:  13.45 cm.

Answer:

a = 5

Step-by-step explanation:

(x+3)(x+a)(x+7)=x³+15x²+71x+105

(x+3)(x+a)(x+7) = (x²+10x+21)(x+a) = x³ + (10+a)x² + (21+10a)x + 21a

21a = 105

a = 5

check: 21 + 10a = 71   ... 71x

            10 + q = 15  .... 15x²

Answer:

That would be 11 my good sir :) (or ma'am)

Step-by-step explanation:

starting from 3 movies we have 4 possible outcomes: 3, 4, 5, and 6.

We have 6 of the 20 students, who watched 3 movies over the break.

Out of the 20 students, 4 watched 4 movies over the break.

Out of the 20 students, none watched 5 movies over the break.

Lastly, 1 student watched up to 6 movies on the break.

Adding up all the students who watched 3 or more movies on the break, we get 11.

1 + 0 + 4 + 6 = 11

Step-by-step explanation:

Answer:

I guess that we want to find the displacement between Andrew's house and his uncle's house.

Assuming that he drove in a straight line, we can use the relationship:

Distance = Speed*Time.

We know that he drove for 6 hours, and the speed was 48 miles per hour, then the distance will be:

distance = 6h*48mi/h = 288 mi

This means that the total distance is 288 miles.

Its D Dude!

Step-by-step explanation:

Answer: x= -8 and y= 1

Step-by-step explanation:

First, let's work on your first equation,3x+3y=-21

This means, see if it can be simplified at all before attempting to solve it.

Multiply x and 3

Multiply x and 1

The x just gets copied along.

The answer is x

x

3*x evaluates to 3x

Multiply y and 3

Multiply y and 1

The y just gets copied along.

The answer is y

y

3*y evaluates to 3y

3*x+3*y evaluates to 3x+3y

Because of the minus sign

21 becomes - 21

The answer is -21

So, all-in-all, your first equation can be written as: 3x+3y = -21

Now, let's work on your second equation,x+y=-7 x+y evaluates to x+y

Because of the minus sign

7 becomes - 7

The answer is -7

So, all-in-all, your second equation can be written as: x+y = -7

After this initial survey of the equations, the system of equations we'll set out to solve is:

3x+3y = -21 and x+y = -7

Let's start by solving 3x+3y = -21 for the variable x.

Move the 3y to the right hand side by subtracting 3y from both sides, like this:

From the left hand side:

3y - 3y = 0

The answer is 3x

From the right hand side:

The answer is -21-3y

Now, the equation reads:

3x = -21-3y

To isolate the x, we have to divide both sides of the equation by the other variables

around the x on the left side of the equation.

The last step is to divide both sides of the equation by 3 like this:

To divide x by 1

The x just gets copied along in the numerator.

The answer is x

3x ÷ 3 = x

To divide -21-3y by 3

divide each term in -21-3y by 3 term by term.

-21 ÷ 3 = -7

To divide y by 1

The y just gets copied along in the numerator.

The answer is y

-3y ÷ 3 = -y

The solution to your equation is:

x = -7-y

Next, let's solve x+y = -7 for the variable y.

Move the x to the right hand side by subtracting x from both sides, like this:

From the left hand side:

x - x = 0

The answer is y

From the right hand side:

The answer is -7-x

Now, the equation reads:

y = -7-x

To isolate the y, we have to divide both sides of the equation by the other variables

around the y on the left side of the equation.

and this is the final solution to your equation.

Now, plug the earlier result, x=-7-y, in for x everywhere it occurs in

y=-7-x.

This gives y=-7-(-7-y). Now all we have to do is solve this for y,to have our first solution.

Because of the minus sign

7 becomes - 7

The answer is -7

Because of the minus sign

7 becomes - 7

The answer is -7

-7-y evaluates to -7-y

-7 - -7 = 0

The answer is y

-7-(-7-y) evaluates to y

Move the y to the left hand side by subtracting y from both sides, like this:

From the left hand side:

y - y = 0

The answer is 0

From the right hand side:

y - y = 0

The answer is 0

Now, the equation reads:

0 = 0

To isolate the y, we have to divide both sides of the equation by the other variables

around the y on the left side of the equation.

The last step is to divide both sides of the equation by 0 like this:

Sorry, can't divide by zero! Stop! Everything below this line is wrong.

0 ÷ 0 = 1

Sorry, can't divide by zero! Stop! Everything below this line is wrong.

0 ÷ 0 = 1

The solution to your equation is:

1 = 1

Lastly, to find the solution for x, we plug this answer for y into the earlier result that

x=-7-y.

This gives x=-7-(1). Now, simplify this.

Because of the minus sign

7 becomes - 7

The answer is -7

-7-(1) evaluates to -8

x= -8

Answer:

Step-by-step explanation:

a) Equation of Parallel line to the given line and passes through the point (-6, -4)

We know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Given the line

y = -5x+4

comparing with the slope-intercept form of the line equation

The slope of the line = m = -5

We know that parallel lines have the same slope. Thus, the slope of the line parallel to the line y = -5x+4 will also be: -5

So, the equation of the line parallel to the given line and passes through the point (-6, -4) will be:

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -5 and the point (-6, -4)

y - (-4) = -5(x-(-6))

y+4 = -5(x+6)

y+4 = -5x-30

y = -5x-30-4

y = -5x-34

Therefore, the the equation of the line parallel to the given line and passes through the point (-6, -4) will be:

Hence:

Equation of Parallel line: y = -5x-34

a) Equation of Parallel line to the given line and passes through the point (-6, -4)

Given the line

y = -5x+4

comparing with the slope-intercept form of the line equation

The slope of the line = m = -5

We know that a line to perpendicular another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

The slope of new line = – 1/m = -1/-5 = 1/5

So, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 1/5 and the point (-6, -4)

y - (-4) = 1/5 (x-(-6))

y+4 = 1/5 (x+6)

Subtract 4 from both sides

[tex]y+4-4=\frac{1}{5}\left(x+6\right)-4[/tex]

[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]

Therefore, the equation of the line perpendicular to the given line and passes through the point (-6, -4) will be:

[tex]y=\frac{1}{5}x-\frac{14}{5}[/tex]

Hence:

Equation of Perpendicular line: y = 1/5x - 14/5
