HELP ASP YOULL GET 20 POINTS AND BRAINLIEST!!!

Answer:

200 children.

180 adults.

Step-by-step explanation:

let x=Children and y=Adults

create 2 equations.

x+y = 380

2.50x+5.80y = 1544

solve for x in the first equation and plug into the second equation.

x = 380-y

2.50(380-y) +5.80y = 1544

distribute and simplify.

950 + 3.3y = 1544

simplify

3.3y = 594

y = 180

plug y back into first equation and you get that there were 200 children.

The distance between the point (-1,0) and (7,6) is 10.

Distance between the points:

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by

d=√((x2 – x1)² + (y2 – y1)²).

Given,

(−1,0) and (7,6).

Here we need to find the distance between these points.

Apply the values on the formula , in order to solve it,

d = √(7 - (-1))² + (6 - 0)²

When we simplify it, then we get,

d = √(7 + 1)² + (6)²

d = √(8)² + 36

d = √64 + 36

d = √100

d = 10

Therefore, the distance is 10.

When data points are marked on the chart, all data points within a single dependent variable are connected with a line, making it very useful tool for analyzing changes over time for one or more variables.

Step-by-step explanation:

Answer:  [tex](r,\theta) = \left(\sqrt{6}, \frac{\pi}{4}\right)[/tex]

In other words, [tex]r = \sqrt{6} \ \text{ and } \ \theta = \frac{\pi}{4}[/tex] where theta is in radians.

=====================================================

Work Shown:

[tex](\text{x},\text{y}) = (\sqrt{3},\sqrt{3})\\\\r = \sqrt{\text{x}^2+\text{y}^2}\\\\r = \sqrt{(\sqrt{3})^2+(\sqrt{3})^2}\\\\r = \sqrt{3+3}\\\\r = \sqrt{6}\\\\[/tex]

and,

[tex]\theta = \tan^{-1}\left(\frac{\text{y}}{\text{x}}\right)\\\\\theta = \tan^{-1}\left(\frac{\sqrt{3}}{\sqrt{3}}\right)\\\\\theta = \tan^{-1}\left(1\right)\\\\\theta = \frac{\pi}{4} \text{ radians}\\\\[/tex]

Use a calculator or the unit circle to arrive at the last step. Keep in mind that (√3, √3) is in the first quadrant where [tex]0 < \theta < \frac{\pi}{2}[/tex] since both x and y are positive.

We have two relations between length of the trench and time.

Case: we want to know how many feet we can dig in a certain amount of time.

In this case, and in most of the cases, time is the independent quantity.

Therefore, the dependent quantity is the other variable: length of the trench.

For example, we can write a proportional relationship between time (x) and length (y) as:

We know that when x=40 min, y=36 ft, according to the machine advertisement.

Then, we can find k as:

And we can write the relation as:

Answer: the independent quantity is time (in minutes).

NOTE:

Which variable is which depends on what we want to calculate.

If we want to know how much it will take to make a certain length of trench, the independent quantity is the length of the trench. The dependent variable is, in this case, time, as we calculate it from the information about the length of the trench.

If we want to calculate the length of the trench we can dig in a certain time, the independent quantity is time and the dependent quantity is the length of the trench.

The number is 17.

Let's assume that the number is x.

So according to the question twice a number is 34 less than 4 times the number.

Then, the equation formed will be as follows

⇒ 2x = 4x - 34

Solving the equation we get the value of x which is the respective number.

Combine the like terms then proceed with calculations.

⇒ 4x - 2x = 34

⇒ 2x = 34

Divide both sides of the equation by 2.

⇒ x = 17

Hence the number whose twice is 34 less than 4 times the number is 17.

If the website advertised an Airpod rental of $5 a week with a down payment of $10, then the total cost he paid if he rented the Airpod for 6 months is $130

The amount he paid for down payment = $10

The rent amount for the airpod for one week = $5

We know,

There are 4 weeks in a month

Number of weeks in 6 month = 6×4

= 24 weeks

The total amount her paid for if he rented the airpod for 6 months = The amount he paid for down payment + (The rent amount for the airpod for one week ×24)

= 10+5×24

= 10+120

= $130

Jim can make interest-only payments until after 1 year and 6 months.

The interest-only payment enables students to avoid interest capitalization during their school years and during the next six months after graduation.

The six-month period is called the grace period.

Non-capitalization of interest lowers the monthly repayments when payments become due after the grace period.

Amount of student loan = $15,200

Interest rate = 4.29%

Loan period = 10 years

Interest-only period = 1 year and 6 months

Amount of interest per month = $54.34 ($15,200 x 4.29% x 1/12)

Total interest during the interest-only period = $978.12 ($54.34 x 18)

Thus, the interest-only payments last for 18 months.

Answer:

70 ft

Step-by-step explanation:

To find the height of the building, we can use the trigonometric relationship between the angle of elevation, the distance from the object, and the height of the object.

In this case, we have a right triangle formed by the observer, the top of the building, and the base of the building. Therefore, we can use the tangent trigonometric ratio, since the height of the building is the opposite the angle of elevation, and the distance between the observer and the building is the side adjacent the angle.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]

Let "x" be the height of the building.

Let "d" be the initial distance from the observer to the building.

The angle of elevation changes from 15° to 30° as the observer advances 140 feet toward the building.

(See the attachment for a visual representation).

Based on this information, we can set up the following equations:

[tex]\tan 15^{\circ}=\dfrac{x}{d}[/tex]

[tex]\tan 30^{\circ}=\dfrac{x}{d-140}[/tex]

Rearrange both equations to isolate d:

[tex]d=\dfrac{x}{\tan 15^{\circ}}[/tex]

[tex]d=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

Solve this system of equations by the method of substitution.

[tex]\dfrac{x}{\tan 15^{\circ}}=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

[tex]\dfrac{x}{\tan 15^{\circ}}-\dfrac{x}{\tan 30^{\circ}}=140[/tex]

[tex]\dfrac{x\tan 30^{\circ}-x \tan 15^{\circ}}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]\dfrac{x(\tan 30^{\circ}- \tan 15^{\circ})}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]x=\dfrac{140\tan 30^{\circ}\tan 15^{\circ}}{\tan 30^{\circ}- \tan 15^{\circ}}[/tex]

[tex]x=\dfrac{140\cdot \frac{\sqrt{3}}{3}(2-\sqrt{3})}{\frac{\sqrt{3}}{3}- (2-\sqrt{3})}[/tex]

[tex]x=\dfrac{\dfrac{140(2\sqrt{3}-3)}{3}}{\dfrac{4\sqrt{3}-6}{3}}[/tex]

[tex]x=\dfrac{140(2\sqrt{3}-3)}{2(2\sqrt{3}-3)}[/tex]

[tex]x=\dfrac{140}{2}[/tex]

[tex]x=70[/tex]

Therefore, the height of the building is exactly 70 feet.

When the graph of a relationship shows a line that passes through the origin, then it is proportional.

If a connection's graph is a line that runs through its origin, it is proportional. If there isn't a line or ray that does this, the ratio isn't proportional. The equation for the proportionality constant is K = y/x.The equation that describes the slope of a straight line in relation to its origin is identical to this one.

When the graph of a proportional connection passes through the origin, any ratio in the proportional relationship can be found.

A relationship is proportional if its graph is a line or ray that passes through the origin. It is not proportional if the line or ray does not go through the origin.

[ where, h1, h2, h3... hn represents roots of that polynomial, and " a " is the stretch of curve]

And by that, we can sort out the roots of given polynomial that are :

Since there are four roots, the least degree polynomial formed will have bi - quadratic polynomial.
