What are the dimensions of this matrix? I WILL MARK BRAINLIEST.

By using simultaneous linear equation, it can be calculated that 200 adult tickets and 400 student tickets were sold and the ticket sale falls $1320 below the goal of $3300.

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation. Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

The simultaneous linear equation needs to be solved

Let d represents the number of adult tickets and s represents the number of student tickets

Their auditorium holds 600 people

d + s = 600 ..... (1)

Price of adult ticket = $7.50

Price of student ticket = $4.50

Total price = $(7.50d + 4.50s)

Therefore,

7.50d + 4.50s = 3300

5d + 3s = 2200 ..... (2)

Multiplying (1) by 3

3d + 3s = 1800.... (3)

Subtracting (3) from (2)

2d = 400

d = 200

Putting the value of d in (1)

200 + s = 600

s = 600 - 200

s = 400

Now, Total tickets sold = d + 2d = 3d

d = 120

s = 240

Number of student ticket sold = 240

Number of adult ticket sold = 120

Total cost = 240  4.50 + 120  7.50

= $1980

Fall in ticket sale = $(3300 - 1980) = $1320

Answer:85

Step-by-step explanation:

The discount in dollars is $768.

This is a question of simple subtraction.

A sale price is the discounted price at which goods or services are being sold. This price is usually offered for a limited period of time

Discounted Amount means an amount equal to the sum of the Offer Discount, Volume Discount and Payment Discount, applied to the List Price of all Eligible Products ordered by the Customer under these Terms.

Larry and Donna bought a sofa at the sale price of $1152.

The original price of the sofa was $1920.

So, Discounted amount of the sofa= (Original price of the sofa- Sale price of the sofa)

i.e, ($1920-$1152)=  $768.

Answer:

For example:

Answer:

Kathy is 48 years old and Samantha is 12.

Step-by-step explanation:

This is a challenging question that requires some interpretation.  Let K and S stand for the current ages of Kathy and Samatha.

We are told that:  K+S = 60

And, in 8 years:  K+8 and S+8

"Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago"  ["3 years ago:"  from now or in 8 years.  I'll interpret it as from now, or (S-3)]

(K+8) = 3(S+8-3)+5   ["5 years older than 3 times as old as Samantha was 3 years ago"]

(K+8) = 3(S+5)+5

K+8 = 3S+20

 K = 3S+12

---

Rearrange the firts equation to isolate K

K = 60-S

Now use this definition of K in the previous equation:

K = 3S+12

60-S = 3S+12

4S = 48

S = 12

K+S = 60

K+12 = 60

K = 48

=====

CHECK

Does K + S = 60?   48+12 = 60 YES

In 8 years, will Kathy will be 5 years older than 3 times as old as Samantha was 3 years ago?

   K = 48+8 = 56

   S = 12+8 = 20

Three years ago S was 9.

(K+8) = 3(S+8-3)+5

(K+8) = 3(12+8-3)+5

K + 8 = 3(17)+5

K = 48

===

Kathy is 48 years old and Samantha is 12.

Answer: The height of the balloon in meters x seconds after it begins to ascend can be represented by the equation y = mx + b, where m is the slope (the rate of change in height) and b is the y-intercept (the initial height of the balloon).

Given that the balloon is hovering 104 meters above the ground and begins to ascend at a rate of 11 meters per second, we can substitute these values into the equation:

y = 11x + 104

This equation is in slope-intercept form, the slope (m) is 11 and the y-intercept (b) is 104. This equation represents the height of the balloon in meters x seconds after it begins to ascend.

To find the height of the balloon after 19 seconds, we can substitute x = 19 into the equation:

y = 11(19) + 104 = 209 meters

So the hot air balloon is 209 meters high after 19 seconds.

The inequality that can be used to solve for how many x paintings can be displayed is 22x + 9 <= 315

Step-by-step explanation:

This inequality states that the total square footage of the paintings and the sign must be less than or equal to 315 square feet. Each painting takes up 22 square feet, and the sign takes up 9 square feet, so the total square footage is represented by the expression 22x + 9.

The inequality states that 22x + 9 <= 315 which means for any number of paintings she displays it should be less than or equal to 315 sq.ft.

The other options:

22x + 9 315: the inequality is less than instead of less than or equal to, which means that the total cost should be less than 315 sq.ft which is not always the case.

22x + 92 315: the coefficient of x is 22 instead of 22 and the 92 is placed in a wrong position.

9x+22 315: the coefficient of x is 9 instead of 22 and the 22 is placed in a wrong position.

Answer:

We know that the ratio of female students to the total number of students is 4 to 9.

That means that for every 4 female students, there are 9 students in total.

So, we can set up the proportion:

4/9 = x/264

where x is the total number of students.

Solving for x, we get:

x = (4/9)*264 = 96

Since the ratio of teachers to students is 1 to 11, then for every 11 students there is 1 teacher, we can set up the proportion:

1/11 = y/96

where y is the total number of teachers.

Solving for y, we get:

y = (1/11)*96 = 8.72 ≈ 8

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - [tex]\frac{2}{3}[/tex] and (a, b ) = ( - 11, - 13 ) , then

y - (- 13) = - [tex]\frac{2}{3}[/tex] (x - (- 11) ) , that is

y + 13 = - [tex]\frac{2}{3}[/tex] (x + 11)

Answer:

Step-by-step explanation:

The value of y is pi over 6. To solve for y, we use the fact that the sine of a sum is equal to the sum of the sines of each individual angle multiplied by the cosine of the other angle. This can be expressed mathematically as sin(x+y) = sin(x)cos(y) + cos(x)sin(y).

Substituting the given values into the equation, we have:

sin(x+y) = (√2/2)sin(x) + (√2/2)cos(x)

Rearranging, we can solve for y:

y = arcsin((√2/2)sin(x) + (√2/2)cos(x)) - x

Since x is equal to pi over 2, we can calculate y as follows:

y = arcsin((√2/2)sin(pi/2) + (√2/2)cos(pi/2)) - (pi/2)

= arcsin((√2/2)(1) + (√2/2)(0)) - (pi/2)

= arcsin(√2/2) - (pi/2)

= pi/6

Therefore, the value of y is pi over 6.

The point (-1, 6) is on the lines y = 5x + 3 and y = 2x + 4​

From the question, we have the following parameters that can be used in our computation:

Point = (-1, 6)

Also, we have

y = 5x + 3

y = 2x + 4​

Substitute the known values in the above equation, so, we have the following representation

6 = 5(-1) + 3 = -2 -- false

6 = 2(-1) + 4 = 2 --- false

Hence, the point is not one the line
