Find 3x-y-3z if x=-2, y=1, z=-2

Answer: 2000 tickets were sold

Step-by-step explanation:

8000 divided by 40 percent is 200

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D s correct.

It is given that 40 percent of the tickets were sold in the first hour and 800 tickets were sold in the first hour,

Let the total ticket be x

40% of x =800 tickets

x = 800/40%

x=800×100/40

x=20×100

x=2000

As a result

40% of 2000 =800 tickets

(40/100)×2000 = 800

Rearrange the equations we get,

800/2000=(40×20)/(100×20),

Hence, if 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

Answer:

6

Step-by-step explanation:

6*4-10=14

Answer: The number is 106.4

Step-by-step explanation:

Let the number be x

Mar halves the number becomes = x x 1/2  to get 53.2

The equation to solve this problem is  x/ 2 = 53.2

Such that to find x

x/2= 53.2

x =  2 x 53.2= 106.4

The number is 106.4

Answer:

31.40 ft^2

Step-by-step explanation:

You are trying to find the circumference, C = 2 * r * 3.14

1. To get the radius you divide the diameter by 2: 10 / 2 = 5

2. Plug your radius into the equation

C = 2 * 5 * 3.14

3. Your final answer should be 31.40 ft^2

Given that: The perimeter of the equilateral triangle is 42 inches. Side of the triangle=Perimeter/3=42/3=14 inches. The height of the triangle is 12 inches

Step-by-step explanation:

12 inches hope it helps

Answer:

C. 9.24

Step-by-step explanation:

x is the height here, looking at the triangle.

To find x, however, we first have to find the hypotenuse. To formula for that is b (side we know)/cos(α) (angle we know). Substitute b for 6, and α for 57.

6/cos(57) would equal about 11.0647.

Now back to x. To figure that out, subtract 6² from 11.01647². Then, find the square root of that.

x = √11.01647² - 6²

x = √121.3626112609 - 36

x = √85.3626112609

x = 9.23918888544335

x ≈ 9.24, so C is the answer.

Answer:

1. 0-9

2. 0-6

3. 0-6

Step-by-step explanation:

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

(ik you might not need this anymore, but I'm hoping it proves useful to others)

All three numbers in the set are in the range it would mean that all three couples prefer indoor weddings is  0-9, 0-6 and 0-6.

We have given that,

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings.

The Range is the difference between the lowest and highest values.

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

Answer: B -4

Step-by-step explanation:

Value of coefficient of the squared term in the parabola's equation = -4

Correct option is B.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given,

Vertex of parabola (h,k) = (3, 5)

y = 6 for x = -1

Parabola opens horizontally left side

Vertex-form equation of parabola

x = a(y - k)² + h

-1 = a(6 - 5)² + 3

-1 = a(1) 3

a = -4

Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Answer:

The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Step-by-step explanation:

Total members=13000

Membership charge per month=$7

Increase in Membership charge per month=$1

For each $1 monthly increase in membership fee, the club loses approximately=500 members

For 1 month, 1 dollar decrease is 500 × 1

For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]

The increase in membership fee is 7 + [tex]x[/tex]

After that,

Monthly revenue = Number of members × Monthly fee

Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]

[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
