The distance that Ann travelled is; 3.61 ft

Pythagoras Theorem is defined as the way in which you can find the missing length of a right angled triangle.

Ann and Elena form the vertical leg of a right angle triangle of length = 3ft. Elena and Rob form the opposite side of the right angle triangle of length = 2 ft.

Using the Pythagorean theorem to find the distance that Anna traveled which is the length of the hypotenuse of the right angle triangle; let that length be x. Then:

x = √(3² + 2²)

x = √ 13

The measure of angle R is 16.1°

Law of Sines In trigonometry, an equation relating the lengths of the sides of any triangle to the sines of its angles.

Given that, a triangle RST, with one angle S = 39° and RT = 25, ST = 11

We need to measure the angle R,

Using law of sine,

Sin R / TS = Sin T / RS = Sin S / RT

Sin R / 11 = sin 39° / 25

Sin R = 11 × sin 39° / 25

Sin R = 0.2769

R = sin⁻¹(0.2769)

R = 16.1

Hence, the measure of angle R is 16.1°

At the point of tangency, a tangent to a circle is perpendicular to the radius.

A tangent is a line that extends from a point on the circle to two points that are eternally close to one another. To put it another way, we can say that tangents are lines that precisely cross a circle at a certain location. Where the tangent touches the circle is known as the point of tangency. An angle is tangent to the radius at the point of tangency. This is a key component of geometric constructions and proofs, and as such, it is related to a number of theorems. One by one, we will examine them.

Theorem: 1

By connecting the center with the point of tangency, a radius is produced. A circle's tangent at a given location is perpendicular to its radius. Simply adhere to the diagram below: Here AB⊥OP

Theorem:2  

According to this theorem, two tangents traced to a circle from a single exterior point have equal numbers of tangent segments. Line connecting the exterior point and the point of tangency is referred to as a tangent segment.

Hence the theorem of the tangent of circle mentioned above.

Aaron should answer 3 open-ended questions and 0 multiple-choice questions to get a maximum of 3 * 20 points/question = 60 points

Aaron has 45 minutes to answer the questions, so he has 45 minutes / 15 minutes/question = 3 open-ended questions that he can answer.

For the remaining questions, he has 45 minutes - (3 * 15 minutes) = 45 minutes - 45 minutes = 0 minutes.

So he cannot answer any more open-ended questions.

He can answer 0 minutes / 1 minute/question = 0 multiple-choice questions.

The  temperature when the plane reaches an altitude of ​3000ft is 51.8 F

Temperature is the degree of hotness or coldness of an object.

Given here: the temperature drops every 1.2 F for every thousand feet ascend.

Thus if the temperature on the ground is 55.4 F

When the plane ascends to 3000 feet the number of temperature drops would be 3 .

Thus drop in temperature is 1.2×3=3.6 F

Therefore the temperature at an altitude at an altitude of 3000 ft. is

55.4-3.6=51.8 F

Hence, The  temperature when the plane reaches an altitude of ​3000ft is 51.8 F

Step-by-step explanation:

Just divide 1,004.7 by 59.1

Step-by-step explanation: To find the values of l and m, we need to solve the equation 15 - 28i = 3l + (4m)i for l and m.

First, we can move all the terms with i to one side of the equation:

15 = 3l + 4mi

-28i = 4mi

To solve for m, we can divide both sides by 4i:

-28i/4i = m

m = -7

Now that we know the value of m, we can substitute it back into the equation to solve for l:

15 = 3l + 4(-7)i

15 = 3l - 28i

3l = 15 + 28i

To solve for l, we can divide both sides by 3:

l = (15 + 28i)/3

So the values of l and m are l = (15 + 28i)/3 and m = -7

Step-by-step explanation:

They sold 400 student tickets and 200 student tickets.

And at a certain performance, they sold 100 adult tickets and 200 student tickets.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

Given, Let 'x' represents the number of adult tickets and 'y' represent the number of student tickets.

So, The two equations can be formed as,

x + y = 600 and 7.5x + 4.5y = 3300.

Multiplying equation 1 by 7.5x we have 7.5x + 7.5y = 4500 and subtracting it from equation 2 we have,

- 3y = - 1200.

y = 400 and hence x = 200.

At a certain performance, they sold twice as many student tickets as adult tickets.

y = 2x.

x + y = 300.

x + 2x = 300.

3x = 300

x = 100 and hence y = 200.

100×7.5 + 200×4.5 = 750 + 900 = 1650.

So, they were 3300 - 1650 = $1650 short.

The total amount of time Michelle's family spends at Mount Rushmore is 93.38 minutes, which is equivalent to 1 hour and 33.38 minutes.

The time Michelle and her family spend watching the movie in the visitor center is 14/60 of an hour or 14 minutes. We are told that this accounts for 15% of the total time they spend at Mount Rushmore, so to find the total amount of time they spent at Mount Rushmore, we need to divide the time spent watching the movie (14 minutes) by the percentage of the total time this accounts for (15%). This gives us the equation:

time = 14 / (15/100)

time = 14 × (100/15)

time = 14 × (6.67)

time = 93.38 minutes or 1 hour and 33.38 minutes.

The intersection of the graphs of the inequalities is shown by a compound inequality with a "and" in it.

When two inequalities are separated by "and" or "or," the result is a compound inequality. The intersection of the graphs of the inequalities is shown by a compound inequality with a "and" in it. A number is a compound inequality solution if it also solves the underlying inequality.

Divide a compound inequality into two individual inequalities before solving it. The solution should either be a union of sets ("or") or an intersection of sets ("and"). Inequalities and the graph should then be solved.

Compound inequality comes in two flavors. Both conjunction and disjunction issues are present. Sometimes, the two simple inequalities in these compound inequalities will be separated by the words AND or OR. When resolving compound "and/or" inequalities, start by resolving each inequality separately.

Therefore, the correct answer is option D.

[tex]$$\begin{gathered}-x+4\left(\frac{1}{4} x-3\right)=-4 \\\Rightarrow \\-x+x-12=-4 \\\Rightarrow \\-12=-4 \\\Rightarrow \\x=3\end{gathered}$$[/tex]

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16. If you simplify the equation using an infinite solutions formula or method, you'll get both sides equal, hence, it is an infinite solution. Infinite represents limitless or unboundedness. It is usually represented by the symbol ” ∞ “.

Some equations have infinitely many solutions. In these equations, any value for the variable makes the equation true. You can tell that an equation has infinitely many solutions if you try to solve the equation and get a variable or a number equal to itself.

This system of linear equations can be graphed on a [tex]$x-y$[/tex] plane. The first equation represents a line with slope [tex]\frac{1}{4}[/tex] and [tex]$y$[/tex]-intercept [tex]-3[/tex]. The second equation represents another line with slope [tex]-1[/tex] and [tex]$y$[/tex]-intercept [tex]-4[/tex]. The intersection point of the two lines is the solution to the system of linear equations.

To find the solution, we can substitute the first equation into the second to eliminate [tex]y[/tex] and solve for [tex]x[/tex]

[tex]$$\begin{gathered}-x+4\left(\frac{1}{4} x-3\right)=-4 \\\Rightarrow \\-x+x-12=-4 \\\Rightarrow \\-12=-4 \\\Rightarrow \\x=3\end{gathered}$$[/tex]

If BC = 8 cm, ∠B = 60°and ∠C = 70° then the triangle is an acute triangle and the value of ∠A is 50.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

BC = 8 cm

∠B = 60° and ∠C = 70°.

Now,

The sum of all the angles is 180.

This means,

∠A + ∠B + ∠C = 180

∠A = 180 - 130

∠A = 50

The cafe served 72 regular coffees.

Here are the steps to find the number of regular coffees served:

The method used for this problem is simple arithmetic calculation, specifically percent calculation.

Percent calculation is used to find the proportion of a number in terms of a percent. To perform a percent calculation, you multiply the original number by the percent (expressed as a decimal) and then round the result to the desired number of decimal places. In this case, the original number is 80 and the percent is 90, which we first convert to 0.90 (by dividing by 100).

You could determine that this method was used because the problem statement asked for the proportion of regular coffee in terms of percent (90%) of the total number of coffees served (80). To find this proportion, you needed to multiply 80 by 0.9, which is equivalent to 80 * 90%.
