If 24 = 118, what is the measure of each of the other
angles?

Answers

Answer:

Step-by-step explanation:

Lines l and m are the parallel lines and line n is a transversal intersecting parallel lines.

Since, m∠2 = m∠4 = 118° [Given]

m∠2 = m∠6 = 118° [Corresponding angles]

m∠4 = m∠8 = 118° [Corresponding angles]

m∠1 + m∠2 = 180° [Linear pair of angles]

m∠1 = 180° - 118° = 62°

m∠1 = m∠5 = 62° [Corresponding angles]

m∠3 = m∠1 = 62° [Corresponding angles]

m∠7 = m∠5 = 62° [Corresponding angles]

find the measures of 1 and 4 if 2 = 119 and = 61

Answers

Answer:

1 = 61

4 = 119

Step-by-step explanation:

Alternate angles

Answer:

1 = 61 and 4=119

Step-by-step explanation:

If 2=119 then the other side of the angle which is 1 has to equal the sum of 180-119

if you reflected 2 across the x and y axis or in other words swapped places with the angel diagonal from it, this should answer the same thing as 2 hence why 2 equals 4 equals 119

3 would equal 1 which equals 61 as they both make 180 when paired with the angle directly next to it

Which is a correct first step in solving the inequality -4(2x - 1) > 5 - 3x?

Answers

Step-by-step explanation:

opening the bracket,the equation therefore is

-8x + 1 > 5 - 3x

add 8x to both sides

- 8x + 8x +1 > 5 - 3x + 8x

1 > 5 + 5x

subtract 5 from both sides

1 - 5 > 5 - 5 + 5x

-4 > 5x

Divide through by 5

-4/5 > x

which is therefore written is

x < -4/5

__________________________________________________________

We can prove this is the answer by dividing both numbers.

__________________________________________________________

[tex]17.51[/tex] = [tex]\frac{1751}{100}[/tex]

[tex]3.4[/tex] = [tex]\frac{17}{5}[/tex] = [tex]3\ \frac{2}{5}[/tex]

__________________________________________________________

[tex]\frac{1751}{100}[/tex] [tex]\div[/tex] [tex]\frac{17}{5}[/tex] = [tex]?[/tex]

[tex]\frac{17.51}{3.4}[/tex] [tex]or[/tex] [tex]5.15[/tex]

So, that means the answer is [tex]5.15[/tex]

7. Use the base angles of triangle ABC to find the measure of angle CBD.

Answers

Answer:

96

Step-by-step explanation:

For those of you who have an 84 angle for angle D and E isosceles trapezoid the base legs will be equal due to the congruent legs, all of the interior angles of a trapezoid will add up to 360, D and E equal 84, 360-84-84 would be 192, now since the base angles are equal due to the congruent legs 192/2 would be 96. Angles B and C are 96.

The external angles of a triangle are those created outside of it. The measure of ∠CBD is 132°.

What is an exterior angle?

The external angles of a triangle are those created outside of it. In other terms, a triangle's external angle is the angle produced between one of its sides and its neighbouring extended side.

The diagram for the given condition can be made as shown below.

In a triangle, the sum of two interior angles is equal to the exterior angle for the angle which is left. Therefore, the measure of ∠CBD can be written as,

∠CBD = ∠BAC + ∠BCA

∠CBD = 43° + 89°

∠CBD = 132°

Hence, the measure of ∠CBD is 132°.

The complete question is:

Triangle ABC with the measure of ∠A equal to 43° and the measure of ∠C equal to 89°. Ray AD passes through point B, creating external angle CBD.

Based on the information provided, what is the measure of ∠CBD?

determine the equation of the line that passes through points (-4,5) and has a slope of m = -3

Answers

Answer:

y=-3x-7

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,5) and has a slope of -3.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -3. So you can right away fill in the equation for a line somewhat to read:

y=-3x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,5). When x of the line is -4, y of the line must be 5.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).

So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,5). y=mx+b or 5=-3 × -4+b, or solving for b: b=5-(-3)(-4). b=-7.

The revenue for a company producing widgets is given by y = -10x2 - 25x + 125, where x is the price in dollars for each widget. The cost of the production is given by y = 60x - 10. Determine the price that will allow the production of the widget to break even.

Answers

When they create 3.44 products and make a revenue of $76.027, they will break even.

Step-by-step explanation:

To do this, simply graph the 2 equation in a graphing calculator and analyze the graph for where the 2 graphs intersect. Discard the negative intersection because we cannot have a negative production. You should see that your intersection point is (3.441, 76.027).
