The sales tax was $0.60.

Answer: 97%

Step-by-step explanation:

If for the 3 exams, the mean was 83% and the first two were 76%, that means..

76 + 76 = 152 (divided by two = 76%/current mean)

In order to get an average of 83%, Colin has to have a score that is higher than 76% and somewhat closer to above 90%.

By doing trial and error (testing different percents between 76% and 80%),  you can come to the conclusion that, 76% + 76% + 97% = 249 / 3 = 83

We can represent the sinusoidal function for Tarzan's motion as given below.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given is that Tarzan is swinging back and forth on his grapevine. As he swings, he goes back and forth across the riverbank, going alternately over land and water. Jane decides to model mathematically his motion and starts her stopwatch.

Assume the sinusoidal equation to be -

y = Asin(ωt)

We can represent the coordinates as -

For {t} = 2, {y} = -23. So -

- 23 = Asin(2ω)                                                    ... { 1 }

For {t} = 5, {y} = 17. So -

17 = Asin(5ω)                                                       ... { 2 }

Therefore, we can represent the sinusoidal function for Tarzan's motion as given above.

Answer:

Step-by-step explanation:

The correct answer is C: The vertices always lie on the circle.

In Poincaré's system, an equilateral triangle is a unique type of triangle in which all three sides are equal in length and all three angles are equal to 60 degrees. Since the vertices of an equilateral triangle lie on the circumference of a circle, it can be said that the vertices always lie on the circle.

The other options, A and B, are also true for equilateral triangles in Poincaré's system, but option C is the best answer because it directly addresses the question of where the vertices lie.

In Poincaré's system, a geometric model of non-Euclidean geometry, the vertices of an equilateral triangle are points that lie on the circumference of a circle.

Here's how this can be demonstrated step by step:

Draw a circle with a center point and a circumference.

Choose three points on the circumference of the circle and connect them with lines to form an equilateral triangle.

Measure the angles at each vertex using a protractor or by counting the number of degrees along the circumference of the circle. In an equilateral triangle, all three angles will be equal to 60 degrees.

Measure the sides of the triangle. In an equilateral triangle, all three sides will be equal in length.

Since the vertices of the triangle are points on the circumference of the circle, it can be concluded that the vertices always lie on the circle.

It is important to note that in Poincaré's system, the relationships between the vertices, sides, and angles of a triangle are different from those in Euclidean geometry. However, an equilateral triangle in Poincaré's system still follows the basic definition of an equilateral triangle, with all sides equal in length and all angles equal to 60 degrees.

Step-by-step explanation:

Slope = rise / run = change in y / change in x  = -30 / 6 = -5

Answer: -5

Step-by-step explanation:

Start with the slope formula

m = (y2 - y1) / (x2 - x1)

Substitute point values in the formula

m = (20 - 50) / (-4 - -10)

Simplify the fraction

m = (20 - 50) / (-4 - -10) = -30 / 6

Solve for slope (m)

m = -5

The student spends x hours tutoring, so y = 15.50x + 35, where x is the number of hours of tutoring and y is the total cost. Therefore, the total cost for a student who receives tutoring for two hours is $66.

According to the dictionary definition, a tutor is a person who provides one-on-one or occasionally small-group teaching. The goal of tutoring is to enable students to help themselves, or to support or mentor them until they reach the point at which they are self-sufficient learners and no longer require a tutor.

Tutors have the ability to, and frequently do, teach students new things. However, when comparing tutoring with teaching, what is being taught  is the main difference. Teachers are meant to teach students new content, and tutors teach students how to learn new content.

The total mass of all three boxes to be delivered by the mail carrier is 180,000 grams.

Given the data in the question;

Mass of the boxes carried by the mail carrier.

Mass of first box = 80kg

Mass of second box = 40kg

Mass of third box = 60kg

First, we convert from kilograms to grams.

Note: 1 kg = 1000g

Hence;

Mass of first box = 80kg = ( 80 × 1000 )g = 80000g

Mass of second box = 40kg = ( 40 × 1000 )g = 40000g

Mass of third box = 60kg = ( 60 × 1000 )g = 60000g

Now, we add the mass of the boxes in gram.

80000g + 40000g + 60000g

180,000 grams

Therefore, the total mass is 180,000 grams.

The result of fraction multiplication are:

2/3 x 2/5 = 4/15

4/2 x 6/3 = 4

2/4 x 3/6 = 1/4

2/3 x 6/3 = 4/3

Given that, simplify the following:

2/3 x 2/5

4/2 x 6/3

2/4 x 3/6

2/3 x 6/3

For the expression 2/3 x 2/5:

To multiply fractions, we multiply the numerators together and the denominators together.

So, (2 x 2)/(3 x 5) = 4/15.

For the expression 4/2 x 6/3:

Again, we multiply the numerators together and the denominators together.

Thus, (4 x 6)/(2 x 3) = 24/6 = 4.

For the expression 2/4 x 3/6:

Following the same process, we multiply the numerators and denominators.

Therefore, (2 x 3)/(4 x 6) = 6/24 = 1/4.

Lastly, for the expression 2/3 x 6/3:

Similarly, we multiply the numerators and denominators together.

Hence, (2 x 6)/(3 x 3) = 12/9 = 4/3.

Answer:

270 square units

Step-by-step explanation:

The area of a regular hexagon is given by the equation:

A = (1/2)(a · P)

where a is the hexagon's apothem and P is its perimeter.

1. We can first solve for the hexagon's perimeter by multiplying its side length (given as 15) by 6, since there are 6 sides.

P = 15 · 6 = 90

2. Now, we can plug that perimeter value into the formula for the area of a regular hexagon (above).

A = (1/2)(90 · 6)

A = (1/2)(540)

A = 270 square units

The probability of selecting a Democrat and then an Independent is  (6/16) * (6/15) = 3/40. The probability of selecting two Republicans with replacement is (4/16) * (4/16) = 1/16.

What is probability ?

Probability is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. It is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation. Probability is used in many fields, such as mathematics, statistics, science, engineering, economics, and social sciences, to model and analyze uncertain situations and make predictions about the future based on available data.

(a) selecting a Democrat and then an Independent without replacement.

The probability of selecting a Democrat on the first draw is 6/16, and the probability of selecting an Independent on the second draw, without replacement, is 6/15. So the probability of selecting a Democrat and then an Independent is:

(6/16) * (6/15) = 3/40

(b) selecting two Republicans with replacement.

The probability of selecting a Republican on the first draw is 4/16, and with replacement, the probability of selecting another Republican on the second draw is also 4/16. So the probability of selecting two Republicans with replacement is:

(4/16) * (4/16) = 1/16

The required overall translation is T<−9,−5>(ABC). The correct answer would be option B.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Starting with triangle ABC, we first apply the transformation T<−5,−3>, which means each vertex of the triangle is shifted 5 units to the left and 3 units down. So the triangle becomes A'B'C'.

Next, we apply the transformation T<−4,−2> to triangle A'B'C', meaning that each vertex is shifted 4 units to the left and 2 units down.

To find the overall effect of these two transformations, we can think of the second transformation as shifting the entire triangle produced by the first transformation.

In other words, we're combining the effects of the two transformations by adding the translations together.

So, the overall translation is T<−5 + −4, −3 + −2> = T<−9,−5>,

Thus, the correct answer would be option B: T<−9,−5>(ABC).

After 5 minutes, the altitude of the airplane is 20,500 feet. This means that the airplane has been descending for 5 minutes and has lost an altitude of 10,250 feet.

After 30 minutes, the altitude of the airplane is -29,250 feet. This means that the airplane has been descending for 30 minutes and has lost an altitude of 60,000 feet. The negative value of the altitude indicates that the airplane has landed or is close to landing.

At both 5 minutes and 30 minutes, the airplane is descending. The rate of descent is constant, as represented by the slope of the equation, and is equal to -1025 feet per minute. At 5 minutes, the airplane is still at a high altitude, while at 30 minutes the airplane has landed or is close to landing, as indicated by the negative value of the altitude.
