At the airport, ten people are waiting on standby. two seats become available, one first-class and one coach, There are 90 ways to fill the two seats.

It is given that there are ten people waiting on standby.

Two seats are available, One is first class and another one is coach.

It is required to find how many ways are there to fill the two seats.

A permutation can be defined as the number of ways a set can be arranged.

We have ten people and two seats in which only two people can seat out of ten.

It is a problem based on the permutation concept.

So for the first seat, there are 10 ways to fill the first seat

and for the second seat, there are  [tex](10-1)[/tex] ways to fill the second seat.

If "P" is the number of ways we can assign the seats:

Then, P = 10×(10-1) = 10×9 = 90

Thus, there are 90 ways to fill the two seats.

Answer:

$1,320

Step-by-step explanation:

To find the area of the bedroom, you must multiply the length and the width. 15 multiplied by 12 is 180, so the area of the bedroom is 180 square feet. There are three feet in a yard, so you must divide the area of the bedroom in feet by 3 in order to get the area of the bedroom in yards. 180 divided by 3 is 60, so the area of the bedroom is 60 square yards. In order to find how much it will cost to carpet the room, you must multiply the area of the bedroom in yards by how much carpeting costs per square yard. 60 multiplied by 22 is 1,320, so it will cost $1,320 in order to carpet the room.

Answer:

Step-by-step explanation:

The time required for an account earning compound interest to achieve a particular balance is given by the formula ...

  t = log(A/P)/(n·log(1 +r/n))

where principal P is compounded n times per year at annual rate r. A is the account balance after that time. For this problem, n=1.

__

Here, we have ...

  P = $2000, A = $2500, r = 0.05, n = 1

The number of years is ...

  t = log(2500/2000)/log(1.05) ≈ 4.57 . . . years

__

For A = $3000, this becomes ...

  t = log(3000/2000)/log(1.05) ≈ 8.31 . . . years

The volume of the cone is 35069.35ft^3 which is equivalent to the air the heating and cooling system would accommodate

Data;

The shape of a cone has a spherical base. From the given data, we can find radius of the sphere from this.

[tex]A = \frac{4}{3}\pi r^3\\38000 = \frac{4}{3}* 3.14 * r^3\\4.186r^3 = 38000\\r^3 = \frac{38000}{4.186} \\r^3 = 9077.878\\r = \sqrt[3]{9077.878} \\r = 20.86ft[/tex]

The volume of a cone is given as

[tex]v=\frac{1}{3} \pi r^2 h\\v = \frac{1}{3} * 3.14 * 20.86^2 * 77\\v = 35069.35ft^3[/tex]

Answer:

Step-by-step explanation:

The x-coordinate of a point is the number units to the right of the y-axis where the point may be found. Translating the point to the right adds to the x-coordinate. Translating to the left subtracts from the x-coordinate.

The y-coordinate of a point is the number of units above the x-axis where the point may be found. Translating the point upward adds to the y-coordinate. Translating downward subtracts from the y-coordinate.

__

When a point is translated 3 units right and 2 units down, its x-coordinate has 3 added to it, and its y-coordinate has 2 subtracted from it. We can summarize the transformation like this:

  (x, y) ⇒ (x +3, y -2)

Applying this transformation to the given points, we find ...

  H(0, 0) ⇒ H'(3, -2)

  I(-3, -1) ⇒ I'(0, -3)

  J(-1, -2) ⇒ J'(2, -4)

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

Explanation:

For any parallelogram, the diagonals cut each other in half. Formally this is known as bisection.

What this means is that the pieces AE and CE are the same length.

AE = CE

6x-8 = 2x+24

6x-2x = 24+8

4x = 32

x = 32/4

x = 8

Then we can calculate the length of each piece mention

Both pieces are 40 units long to confirm we have the correct x value.

Therefore,

AC = AE + CE = 40+40 = 80

To write the equation multiply the price per person by x( the number of people that can go) and add the price of parking to get the total cost:

equation: total = 35.75x + 19

to solve for x replace the total with 197.75 and solve for x:

197.75 = 35.75x + 19

Subtract 19 from both sides:

178.75 = 35.75x

Divide both sides by 35.75

X = 5

a total of 5 people can go.
