Answer:

Vertical angles are always equal to one another. In general, we can say that, 2 pairs of vertical angles are formed when two lines intersect.

Step-by-step explanation:

Parallel lines are lines that do not meet at any point in a plane.

Intersecting lines are straight lines that meet or crosses each other at a certain point.

Answer:5o

Step-by-step explanation: you add all of the numbers length with and high the

The Angles (2x + 30)° and (2x + 10)° are forming linear pair , so

[tex] \hookrightarrow \: 2x + 30 \degree+ 2x + 10 \degree= 180 \degree[/tex]

[tex] \hookrightarrow \: 4x + 40\degree = 180\degree[/tex]

[tex] \hookrightarrow \: 4x = 180\degree - 40\degree[/tex]

[tex] \hookrightarrow \: x = 140\degree \div 4[/tex]

[tex] \hookrightarrow \: x = 35\degree[/tex]

now , let's find Angle BOC :

[tex] \hookrightarrow2x + 10\degree[/tex]

[tex] \hookrightarrow \: (2 \times 35)\degree + 10\degree[/tex]

[tex] \hookrightarrow \: 70\degree + 10\degree[/tex]

[tex] \hookrightarrow \: 80\degree[/tex]

Answer:

number = - 1

Step-by-step explanation:

let the number be n then twice the number is 2n , so

2n + 4 = n + 3 ( subtract n from both sides )

n + 4 = 3 ( subtract 4 from both sides )

n = - 1

The number is - 1

Is the salary $1,045,000/week?  Then yes - easy.

Is the salary $1,045.00/week?  Then yes, 19 years will get him there.

(1045/week)*(52 weeks/year) = $54,340/year

$1,000,000/($54,340/year) = 18.4 years

Explanation:

Right-angled triangles have one of their angles to be 90°.

Angles in a triangle is 180°

=>The other two angles will sum up to 90°

Let x represent the other acute angle

2 less than 3 times the size of the other acute angle.

3(x)-2=one angle.

Equating both angles to 90°

=> other acute angle + one angle =90°

=> x+3x-2=90°

=>4x-2=90°

=>4x=90-2

=>4x=88

Divide both sides by 4

x=22°

Other acute angle=22°

One angle= 3(22)-2

=>66-2

=>64°

Proof= 22+64+2+90=180°

Answer:

149

Step-by-step explanation:

Adult ticket = x

Let the student ticket be 2x

2x + x = 447

3x = 447

x = 447/3

x = 149

If the number of student tickets sold was two times the number of adult tickets sold approximately 149 adult tickets were sold for the school play.

Let's assume the number of adult tickets sold as 'x'.

According to the given information, the number of student tickets sold is two times the number of adult tickets sold. So, the number of student tickets sold can be expressed as 2x.

We are also given that the total number of tickets sold is 447. Therefore, we can write the equation:

x + 2x = 447

Combining like terms, we have:

3x = 447

To find the value of x, we divide both sides of the equation by 3:

x = 447 / 3

Using a calculator, we find:

x ≈ 149

Using profit/cost/revenue concepts, it is found that:

----------------------

----------------------

Question a:

The break even point is the value of x for which the revenue is the same as the cost, that is:

[tex]R(x) = C(x)[/tex]

Thus

[tex]5x = 800 + 3x[/tex]

[tex]2x = 800[/tex]

[tex]x = \frac{800}{2}[/tex]

[tex]x = 400[/tex]

400 cookies must be produced and sold to break even.

----------------------

Question b:

The dollar amount is [tex]R(400)[/tex].

[tex]R(400) = 5(400) = 200[/tex]

The dollar amount coming in and going out is $400.

----------------------

Question c:

Profit is revenue subtracted by cost, thus:

[tex]P(x) = R(x) - C(x)[/tex]

[tex]P(x) = 5x - (800 + 3x)[/tex]

[tex]P(x) = 5x - 800 - 3x[/tex]

[tex]P(x) = 2x - 800[/tex]

The profit function is [tex]P(x) = 2x - 800[/tex]

----------------------

Question d:

The profit earned is P(520), thus:

[tex]P(520) = 2(520) - 800 = 240[/tex]

Kimmie will earn a profit of $240.

Answer:

9/12 (75%)

Step-by-step explanation:

There's a total of 12 movies (5+4+3).

Since there are 5 action, there's a 5/12 probability that he selects action.

4 comedies, so 4/12 probability that he selects comedies.

3 dramas, so 3/12 probability that he selects drama.

4+5 = 9 so there's a 9/12 or 75% probability that he won't select drama.
