Conor is going to the movie theater. A ticket to a movie costs t dollars, and there is a 15% amusement tax on each ticket.
a. Conor buys a ticket to see a movie. Write two expressions in terms of t showing his total cost.
b. The price of a movie ticket is $12.49. Use one of the expressions you wrote in part a to find Conor’s total cost, rounded to the nearest penny. Show your work.

Company B charges a $55 initial price plus an extra $0.90 for every mile traveled. For 70 miles, Company A will charge less than Company B.

The occurrence of an unfair and/or uneven distribution of opportunities and resources among the people that make up a society is referred to as inequality. To different individuals and in various settings, the word "inequality" may indicate different things.

$118 in change and unrestricted mileage

B affects the initial $550 and the cost per mile traveled.

Let m stand for the distance covered.

So inequality is

118 < 55 + 0.90 m

= 0.90 m > 118 - 55

= m > 63/0.90

= m > 70

So for 70 miles above company A changed less than company B.

The maximum number of friends that he can invite without going over his limit is 9.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

As per the given,

Fixed fee = $50

Suppose the number of people is x.

Total fee = 50 + 5.50x

Total fee ≤ budget

50 + 5.50x ≤ 100

5.50x ≤ 50

x ≤ 9.09 thus, x = 9

Hence "The maximum number of friends that he can invite without going over his limit is 9".

In 42 6/7 minutes the pool will get filed when all 3 pumps work together.

Given,

Time taken by the pump 1 to fill a pool = 50 minutes

Time taken by pump 2 to fill the same pool = 60 minutes

The time taken by pump 3 to drain the pool = 75 minutes

When all the 3 pumps work together, we have to find the time taken to fill the pool;

Here,

In every minute,

Pump 1 fills 1/50 of pool

Pump 2 fills 1/60 of pool

Pump 3 drains 1/75 of pool

That is,

1/50 + 1/60 - 1/75 = 6/300 + 5/300 - 4/300 = 11 - 4 / 300 = 7/300

The time taken = 300/7 minutes = 42 6/7 minutes

The degree measure of the exterior angle triangle is ∠D = 137°.

Having three vertices and three angles that add up to 180 degrees, a triangle is a three-sided polygon.

given this, the angles D, E, and F in the triangle DEF are (4x + 15), (5x + 32), and 70 respectively.

The sum of the angles of a triangle is now 180°.

Therefore, we may write:  m ∠D m∠ E m ∠F = 180

When all the numbers are substituted, we obtain the following results: (9x + 117 = 180) 9x

= 180 -117 (4x + 15) + (5x + 32) + 70

⇒ 9x = 63

⇒ x = 7

As a result, we obtain m∠ D = (4x + 15)°,

m∠ D = (4 x 7 + 15)°,

m ∠D = (28 + 15)°, and m∠ D = (43)°.

Furthermore, m∠ E = (5x + 32)°

m ∠E = (5 x 7 + 32)°

m ∠E = (35 + 32)°

m ∠E = 67°

Since, The measure of the exterior angle to ∠D = m ∠E + m ∠F

= 67° + 70

= 137°

Thus, The measure of the exterior angle  ∠D will be 137°.

Point E's coordinates are (-7, -1).

The formulas for our new x and y are provided to us. We must first establish our points 1 and 2 before applying this formula. Due to the fact that the issue was sole with the point E that divides the line segment "from J to K,"

the following formula: point 1 = point J = (x1, y1)

Points 2 and K are equal (x2, y2)

The partition segments JE and EK take up a certain amount of the original segment, as indicated by the variables m and n. Given that the ratio is 1:1, then

JE = m = 1

EK = n = 4

Consequently, using the above formulas to calculate for x and y:

x = [1 / (1 + 4)] (25 – (-15)) + (-15) (-15)

x = -7

y = [1 / (1 + 4)] (15 – (-5)) + (-5) (-5)

y = -1

Consequently, point E's coordinates are (-7, -1)

The range is all real integers bigger than or equal to the range's y-coordinate if a quadratic function opens up. All real integers less than or equal to the range's y-coordinate are in the range if a quadratic function opens downward.

In the given question we have to explain, how we can find the range of a quadratic graph.

Because it is the most fundamental quadratic function, all quadratic functions collectively can be referred to as a family, with this particular function serving as the parent (i.e., not transformed in any way). This function can be used to start broadly generalising the domains and ranges of quadratic functions.

The range is partly determined by the pivotal point, or vertex. The parabola's opening direction is the other. The range is all real integers bigger than or equal to the range's y-coordinate if a quadratic function opens up.

Answer:

(-infinity, -2) ∪ (-3, infinity).

Step-by-step explanation:

To solve this compound inequality, we need to first solve each inequality separately. For the first inequality, 4(z+1) > -4, we can distribute the 4 to get 4z + 4 > -4. Then, we can subtract 4 from both sides to get 4z > -8. Finally, we can divide both sides by 4 to get z > -2.

For the second inequality, 2z - 4 < -10, we can add 4 to both sides to get 2z < -6. Then, we can divide both sides by 2 to get z < -3.

Now that we have solved both inequalities, we need to consider their intersection. Since the inequalities are joined by the "or" operator, the solution is the union of the solutions to each inequality. In interval notation, this is represented as the union of the intervals (-infinity, -2) and (-3, infinity).

Therefore, the solution to the compound inequality in interval notation is (-infinity, -2) ∪ (-3, infinity).

Answer:

The equation y = 34x - 2 is the slope-intercept form of the equation y = 34x + b, where b is the y-intercept, which is the point where the line crosses the y-axis. The value of b in this case is -2, so the equation can be written as y = 34x - 2. This form of the equation makes it easy to find the slope (which is 34 in this case) and the y-intercept (which is -2 in this case) of the line.

The equation of the line passing through the point (-6, -3) and perpendicular to JK with J(-2, -7) and K(6, 5) is y =  -2 / 3x - 7, so option B is correct.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

A line passing through the point (-6, -3) and perpendicular to JK with J(-2, -7) and K(6, 5)

Calculate the slope of the line,

m = 5 - (-7) / 6 - (-)

m = 12 / 8

m = 3 / 2

The slope of a line perpendicular to JK, M = - 1 / 3 / 2 = -2 / 3

Calculate the equation of the line as shown below,

y - (-3) = -2 / 3[x - (-6)]

y + 3 = -2 / 3x - 4

y =  -2 / 3x - 7

Therefore, the equation of the line passing through the point (-6, -3) and perpendicular to JK with J(-2, -7) and K(6, 5) is y =  -2 / 3x - 7.

If the speed of the vehicle is greater than or equal to 60 miles per hour, the angle will be greater than or equal to zero and the trooper should issue a ticket.

Distance is defined as the product of speed and time.

If the speed limit is 50 miles per hour and a speeding ticket is issued for speeds of 10 miles per hour or more over the limit, then the trooper should issue a ticket for any speed greater than 50 + 10 = 60 miles per hour.

In general, the speed of a vehicle is given by the formula v = d/t, where v is the speed, d is the distance traveled, and t is the time it takes to travel that distance.

The angle at which a speeding ticket should be issued is determined by the ratio of the speed of the vehicle to the speed limit. If the speed of the vehicle is greater than the speed limit, then the ratio of the speed of the vehicle to the speed limit will be greater than 1.

Therefore, the trooper should issue a ticket for any angle that is equal to or less than 1.

Alternatively, you could also say that the trooper should issue a ticket when the angle is greater than or equal to zero. Since any number divided by 1 is equal to the original number, this means that the angle will be equal to the speed of the vehicle in miles per hour.

Therefore, if the speed of the vehicle is greater than or equal to 60 miles per hour, the angle will be greater than or equal to zero and the trooper should issue a ticket.

According to ERG theory, frustration over not being able to satisfy a higher-order need may cause regression to a lower level.

ERG theory is a psychological theory put forth by Clayton Alderfer.

ERG concept, An individual will put more effort into the higher category once needs in the lower category are met. An individual will put more effort into the lower category if needs in the higher category are not met.

Maslow's hierarchy of needs was further developed by Alderfer by being categorised into his ERG theory (Existence, Relatedness and Growth). The necessity of meeting the essential material needs of people falls under the existence category. Concerned in the relatedness category is the desire to uphold significant interpersonal connections.

The desire for personal growth is addressed in the growth category. These include the self-actualization traits and the intrinsic component from Maslow's esteem category.

in a simple manner we define the three stages of ERG theory

1. Existence -  what we need from a physiological point of view .

examples- a house , healthcare, etc.

2- Relatedness -  our social needs.

examples -  friendship, social connectivity, national identity, etc.

3-growth -  Self-realization needs.

Answer:

It is not possible to determine whether the lines are parallel based on the information given. To determine whether two lines are parallel, we need to calculate the slope of each line and compare them. The slope is calculated as the change in the y-coordinate divided by the change in the x-coordinate, or (y2-y1)/(x2-x1). Since we only have the coordinates of the endpoints of the lines and not the equations of the lines, we cannot calculate the slope and therefore cannot determine whether the lines are parallel.
