Answer:

7z + 4.5y = 2650

z + y = 450

Step-by-step explanation:

The first equation represents the amount of money made from ticket sales for both adult and child tickets.

The second equation represents the amount of customers, both adult and child, that attended the theatre.

Using both equations you cans find the number of adults and children that attended the theatre.

Cheers.

-----------------------------------------------------

Edit: Solving for the variables

There are two easy ways to solve for these values. The first is using an augmented matrix and solving with that method.

7 4.5 | 2650

1 1 | 450

After are augmented matrix is set up, we simply use row operations on the matrix to solve for 1s on the diagonal.

The second method for solving is equation addition or variable substitution to solve for each variable.

7z + 4.5y = 2650

z + y = 450

7(450-y) + 4.5y = 2650

3150 - 7y + 4.5y = 2650

-2.5y = -500

y = 200

Plug back in y into one of the equations to solve for z.

z + 200 = 450

z = 250

So there were 250 adults and 200 children.

Answer:

26

Step-by-step explanation:

Let's find first the lower quartile in both A and B

steps:

73 and 75 are the smallest consecutive numbers

The lower quartile in A is 74

47 and 49 are the smallest consecutive numbers

The lower quartile in B is 48

Answer:

29

Step-by-step explanation:

To find the lower quartile of each you need to find the median to split them into 2 groups (upper and lower quartile).

Lower quartile of Set A: 73, 75, 79, 81, 84, 85

Lower quartile of Set B: 47, 49, 51, 51, 55, 56

Now you find the median of the 2

Set A: 80

Set B: 51

Lastly you subtract A & B and get 29

Answer: the rate of change of the distance between the car and the person at that instant is 4 meters per second

Step-by-step explanation:

According to the Pythagorean theorem, we have:

d^2 = (12^2 + 9^2)

Differentiating both sides with respect to time:

2d * (dd/dt) = 0 + 2(9) * (9''), Simplifying the equation, we get:

2d * (dd/dt) = 2(9) * (9'')

Substituting the given values:

2d * (dd/dt) = 2(9) * (4) [the car is moving at a constant velocity of 4 m/s]

Simplifying further:

2d * (dd/dt) = 72

we divide both sides by 2d:

dd/dt = 72 / (2d)

substitute this value into the equation to find the rate of change of the distance:

dd/dt = 72 / (2 * 9) = 4 m/s

The rate of change of the distance between the car and the person at that instant is -12/5 meters per second.

Given information:

The person is standing 12 meters east of the intersection.

The car is driving away from the intersection to the north at a constant speed of 4 meters per second.

At a certain instant, the car is 9 meters from the intersection.

Using the Pythagorean theorem, determine D(t) in terms of the car's distance from the intersection, which we'll call x(t).

Since the person is 12 meters east of the intersection, the distance D(t) can be expressed as:

[tex]D(t) = \sqrt{(x(t)^2 + 12^2)[/tex]

Differentiating both sides of the equation with respect to time, we get:

[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * dx(t)/dt[/tex]

So, dx(t)/dt = -4

Substituting this value into the equation for dD/dt, we have:

[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * (-4)[/tex]

[tex]dD/dt = -4x(t) / \sqrt{(x(t)^2 + 144)[/tex]

At the instant when the car is 9 meters from the intersection, substitute x(t) = 9 into the equation:

[tex]dD/dt = -4(9) / \sqrt{(9^2 + 144)[/tex]

          = -36 / √(81 + 144)

          = -36 / √225

          = -36 / 15

          = -12/5

Therefore, the rate of change is -12/5 meters per second.

Answer:

x=10

Step-by-step explanation:

We can use the Pythagorean theorem to find x

The height meets the base at a right angle

The base is bisected ( cut in half) so the base is 6 the height is 8

a^2 + b^2 = c^2

6^2 + 8^2 = x^2

36+64 = x^2

100 = x^2

Taking the square root of each side

sqrt(100) = sqrt(x^2)

10 = x

Answer:

10

Step-by-step explanation:

This triangle is divided into 2 identical rigth triangles.

Answer:

Step-by-step explanation:

triangle BAC is just a larger version of triangle EAD. given that ED is 5cm, and BC is 10cm, triangle BAC must be twice the size of EAD. since the ratio of AD to ED is 4:5, and BC is twice the size, all we need to do is multiply both sides by 2 to find length AC. 4*2 = 8. now we can subtract length AD from AC to get CD. 8 - 4 = 4.

Answer: 3/2

Step-by-step explanation:

Hi, to answer this question we have to write the next expressions::  

Height 1= 8 +12 y

Height 2 =5 +14y

Where y = number of years

Since both heights must be the same

Height 1 = height 2

8+12y = 5+14y

solving for y:

8-5 =14y-12y

3 = 2y

3/2 =y

y = 3/2 years

Feel free to ask for more if needed or if you did not understand something.

8 + 12y = 5 + 14y

12y + 8 = 14y + 5

12y + 8 - 8 = 14y + 5 - 8

12y = 14y - 3

12y - 14y = 14y - 3 - 14y

-2y = -3

(-2y)/-2 = -3/-2

y = 3/2

Answer:

M=-1, N=7

Step-by-step explanation:

Something went wrong on the 4th line.

From the third line, it should read

2x^2-x+6Mx-3M+4

=x(2x-1+6M) - 3M+4

Equating with the RHS,

2x-1+6M = 2x-7

6M = -7+1 = -6

M = -1

Therefore

N = -3M+4 = -3(-1)+4 = 7

or

M=-1, N=7
