By solving a system of equations we can see that there are 400 main-floor seats and 500 balcony seats.

Let's define the two variables:

We know that if all the seats are sold, then the total income is $5,200, we can write the equation:

x*$8 + y*$4 = $5,200

And if 25% of the main-floor and 50% of the balcony seats are sold, then we get an income of $1800, then we can write:

0.25*x*$8 + 0.5*y*$4 = $1,800

x*$2 + y*$2 = $1,800

So we have a system of equations:

x*$8 + y*$4 = $5,200

x*$2 + y*$2 = $1,800

If we subtract twice the second equation for the first one we get:

(x*$8 + y*$4) - (x*$2 + y*$2) = $5,200 - 2*$1,800

x*$4 = $1,600

x = $1,600/$4 = 400

So there are 400 seats on the main-floor.

Using the first equation we can find:

x*$8 + y*$4 = $5,200

400*$8 + y*$4 = $5,200

$3,200 + y*$4 = $5,200

y*$4 = $5,200 - $3,200 = $2,000

y = $2,000/$4  = 500

So there are 500 balcony seats.

45 inches s the perimeter of a regular, triangular yield sign with aside length of 15 in

The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, so its perimeter is equal to the sum of those three lengths.

The perimeter of a square can be easily calculated if one side and all other sides are given as being the same length; for example, a square with sides measuring 5 inches long has a perimeter of 20 inches because 5 x 4 = 20. By multiplying the sum of the length and width by two, one can determine a rectangle's perimeter.

We will use the simple perimeter formula as yield sign is equilateral triangle

So, 15 × 3 = 45 inches

The graph of the compound inequalities with intersection points

(2.21, -0.63) is given below.

Please see the graph attached.

A compound inequality has two inequality statements joined either by the "or" or “and.”

We have,

6x+2y<12 or x-6y>6

We can graph each inequality.

And we also need to see the intersection between the inequalities.

Let,

6x + 2y = 12____(1)

x - 6y = 6_______(2)

From (1)

x = (12 - 2y ) / 6 put in (2)

(12 - 2y) / 6 - 6y = 6

2 - 1/3y - 6y = 6

2 - 6 = (1/3)y + 6y

-4 = 19y / 3

y = -12 / 19

y = - 0.63 put in (1)

6x + 2 x (-0.63) = 12

6x = 12 + 1.26

x = 13.26 / 6

x = 2.21

The point of intersection on the graph is (2.21, -0.63).

Thus the graph of the compound inequalities with intersection points (2.21, -0.63) is given below.

The value of the inventory will be 4000

Bulbs in the warehouse: 2000 bulbs

Cost of each bulb to the manufacturer: 2

Average delivery cost = 0.30

The selling price of the bulb = 2.20

Value of inventory: The monetary value assigned to the items in inventory at the end of an accounting period is known as inventory valuation. The inventory is valued based on the expenses incurred to get it and prepare it for sale.

The biggest current business assets are inventories. You can assess your cost of goods sold (COGS) and, ultimately, your profitability, thanks to inventory valuation.

The value of the inventory is calculated on the cost price, therefore the value of the inventory will be:

= Cost of each bulb*Number of bulbs

= 2000*2

= 4000

So, the value of the inventory will be 4000

The Three consecutive numbers will be 24.5, 25.5, 26.5

We have to take three consecutive numbers. Let the first number be 'x' and the consecutive two numbers be (x + 1), and (x + 2).

It is given that the square of the third number is greater than the square of the second number by 52. We need to create an equation that represents this situation. So, we get :

  => (x + 2)² = (x + 1)² + 52  

  =>  x² + 4x + 4 = x² + 2x + 1 + 52

  =>  x = 49/2      =>  x = 24.5

We get value of x = 24.5. Putting this value of x in consecutive numbers we get the first, second, and third numbers as 24.5, 25.5, and 26.5 respectively.

Hence, we get the three consecutive numbers: 24.5, 25.5, and 26.5

Answer:

Area of two rooms is 357 square feet

Length of the baseboards = 89.5 ft

Step-by-step explanation:

Area of the room = length * width

Area of the two rooms = area of bigger room + area of smaller room

                                       = 19 * 15 + 8 * 9

                                        = 285 + 72

                                        = 357 square feet

To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.

Bigger room:

length = 19 ft

Width = 15 ft

Width of the entry =  2 1/2 ft = 2.5 ft

Width of the opening between two rooms = 5 ft

Perimeter of bigger room = 2l + 2w - 5 - 2.5

                                          = 2*19 + 2*15 - 7.5

                                          = 38 + 30 - 7.5

                                           = 60.5 ft

Smaller room:

length =  8ft

Width = 9 ft

Width of the opening = 5 ft

Perimeter of the smaller room = 2*8 + 2*9 - 5

                                                   = 16 + 18 - 5

                                                   = 29 ft

Length of the base board = 60.5 + 29

                                           = 89.5 ft

Step-by-step explanation:

the relationship between x and y when x varies directly is 4 x = y.

We know that when x varies directly with y, then:

x = k y

Now, we have x = 5 and y = 20

Substituting the values in the expression, we get that:

5 = 20 k

k = 5 / 20

k = 1 / 4

So, we get the relation as:

x = 1 / 4 y

4 x = y

Therefore, the relationship between x and y when x varies directly is 4 x = y.

Let the initial salary be x.

Set equation and solve for x:

Answer:

The original salary is $11641.18.

Step-by-step explanation:

The equation will be,

→ x + (x × 2)/100 = 11874

Now the original salary will be,

→ x + (x × 2)/100 = 11874

→ x + 0.02x = 11874

→ 1.02x = 11874

→ x = 11874/1.02

→ x = 11641.1764706

→ [ x = 11641.18 ]

Hence, original salary is $11641.18.

The coordinates of the vertices E (-8,9), F(-4,9), G(-4,2), and D(2,-8) when rotated 90° counterclockwise around the origin of the new coordinates will be E'( - 9, - 8 ), F'( - 9, - 4 ), G'( - 2, - 4 ), and D'( 8, 2 ).

A point A( x, y ) becomes A' when a point is rotated 90 degrees counterclockwise about the origin ( - y, x ). To put it another way, flip x and y, and make y negative.

Therefore, when point E( - 8, 9 ) is rotated 90° counterclockwise around the origin will be:

E'( - 9, - 8 )

Here,

Alvira and Barry Gomez purchased a home priced at $280,000.

They put down 40%.

We have to find down payment.

And, Amount of the mortgage loan.

What is Down payment?

A sum of money that a buyer pays in the early stages of purchasing an expensive good or service is called down payment.

Now,

Alvira and Barry Gomez purchased a home priced at $280,000.

They put down 40%.

Hence, The down payment = $280,000 x 40%

                                          = $280,000 x 40 / 100

                                          = $112,000

And, Amount of the mortgage loan = Total amount - Down payment

                                                      = $280,000 - $112,000

                                                      = $168,000

Therefore, The down payment is $112,000.

Answer:

  5 inches

Step-by-step explanation:

Whitney wants the greatest length that is an even divisor of both 45 inches and 20 inches.

The length Whitney is looking for is called the "greatest common divisor" (GCD) or "greatest common factor" (GCF) of the two numbers 45 and 20. There are a couple of different ways this can be found.

The prime factors of the two numbers are ...

  45 = 3×3×5

  20 = 2×2×5

The only factor common to the two products is 5. It is the greatest common factor.

Whitney can cut lengths of 5 inches.

Another way to find the GCD is to use Euclid's algorithm. That has you ...

Using this algorithm, we have ...

  45/20 = 2 r 5

  20/5 = 4 r 0 . . . . . The GCD is 5

Whitney can cut lengths of 5 inches.

Answer:

Step-by-step explanation:

You want the distances north and east of the origin that a plane ends up after flying 400 km at a bearing of 25°, then 700 km at 80°.

For some distance r and bearing angle θ, the (north, east) coordinates will be ...

  (north, east) = (r·cos(θ), r·sin(θ))

For the trip at hand, the final coordinates of the plane are ...

Distance north = (400 km)cos(25°) +(700 km)cos(80°)

  = 362.52 km +121.55 km = 484.07 km

B is about 484 km north of O.

Distance east = (400 km)sin(25°) +(700 km)sin(80°)

  = 169.05 km +689.37 km = 858.41 km

B is about 858 km east of O.

Additional comment

Rectangular coordinates of a point at distance r from the origin and an angle θ measured CCW from the +x axis are given by ...
