Answer:

Width of rectangle = [tex]\mathbf{9x^6y^4}[/tex] yards

Step-by-step explanation:

The area of a rectangle = [tex]54x^9y^8[/tex]

The length of rectangle = [tex]6x^3y^4[/tex]

We need to find the width of rectangle.

The formula used is:

[tex]Area=Length\times Width[/tex]

Putting values and finding width of rectangle

[tex]Area=Length\times Width\\54x^9y^8=6x^3y^4\times Width\\Width=\frac{54x^9y^8}{6x^3y^4}[/tex]

Using exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

[tex]Width=9x^{9-3}y^{8-4}\\Width=9x^6y^4[/tex]

So, we get Width of rectangle = [tex]\mathbf{9x^6y^4}[/tex] yards

Answer:

Conversion factors are easier to use because they are constant.

For example, if you needed to convert, say, 13 kilometers to feet, a conversion factor would help. You would use proportions to convert given a similar conversion.

Essentially, you're answer is correct, because one way to convert units may be different than somebody else's. For you, might be using proportions, which is fine.

Answer:

Step-by-step explanation:

the easiest thing would be to take $21.70 divide that by 4 then you will get $5.425 and then if you times that by 4 you get $21.70  it also depends on the state for tax but I would say that $23 on the safe side so I would say that the answer is 1% tax rate hope this helps and good luck.

P.S this may be wrong but i hought it would try to help :)

Answer:

Number of children tickets = 400

Number of students tickets = 300

Number of adults tickets = 800

Step-by-step explanation:

Let the number of children tickets = [tex]x[/tex]

Let the number of students tickets = [tex]y[/tex]

Let the number of adults tickets = [tex]z[/tex]

Total number of tickets sold = 1500

Writing the equation:

[tex]x+y+z=1500[/tex] .... (1)

Price for each children ticket = $1.50

Price for each student ticket = $3

Price for each adult ticket = $5

Total money brought in = $5500

[tex]1.5x+3y+5z = 5500[/tex] ..... (2)

Number of student tickets sold was 100 lesser than number of children's tickets.

i.e.

[tex]y = x -100[/tex] ..... (3)

Putting value of [tex]y[/tex] from (3) in equation (1) and equation (2):

[tex]x+x-100+z=1500\\\Rightarrow 2x+z=1600 .... (4)[/tex]

[tex]1.5x+3(x-100)+5z=5500\\\Rightarrow 4.5x+5z=5800 ..... (5)[/tex]

Multiplying equation (4) by 5 and subtracting equation (5) from it:

[tex]5.5x=2200\\\Rightarrow x = 400[/tex]

By equation (3):

[tex]y = 400 - 100 = 300[/tex]

By equation (1):

[tex]z = 1500 - 400 - 300 = 800[/tex]

Therefore, the answer is:

Number of children tickets = 400

Number of students tickets = 300

Number of adults tickets = 800

400 children tickets, 300 college ticket and 800 adult tickets were sold.

Let x represent the number of children tickets, y represent the number of college tickets and z represent the number of adult tickets.

Since 1500 tickets were sold, hence:

x + y + z = 1500     (1)

They brought in $5500, hence:

1.5x + 3y + 5z = 5500   (2)

Also:

y = x - 100

-x + y = -100     (3)

Solving equations 1, 2 and 3 simultaneously gives:

x = 400, y = 300, z = 800

400 children tickets, 300 college ticket and 800 adult tickets were sold.

Answer:

The equation of the parabola is;

(y-3)^2 = 20(x-2)

Step-by-step explanation:

Here, we want to find the equation of the parabola given the focus and the vertex of the said parabola

Mathematically, we can have the equation represented as;

(y-k)^2 = 4a(x-h)

As we can see that the focus and the vertex lie on the same horizontal line of y = 3

In this case, a = 7-2 = 5

The coordinates of the vertex is (h,k) = (2,3) in this case

where h = 2 and k = 3

So the equation of the parabola will be;

(y- 3)^2 = 4(5)(x-2)

(y-3)^2 = 20(x-2)

6x + 9 + y

Step-by-step explanation:

bien, así que la ecuación se ve así:

4x + 9 - 3y + 2x + 3y

Así que agregamos todas las variables x juntas y las y variables y juntas para simplificar la ecuación:

4x + 2x = 6x

-3y + 3y = y

así que vamos a agregar todas las variables x a las variables x, y las variables y a las variables y:

6x + y + 9

Así que su ecuación una vez simplificada es 6x + y + 9

Answer:

Triangle ADB is congruent to triangle DBC

Step-by-step explanation:

In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.
