X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247

$-2x = $-38

divide -2 by both sides

x=19, meaning that all of the students are members.

tatuchka [14]

The median is a halfway point in the set of data.

List the numbers in order from smallest to largest:

111, 129, 144, 149, 152, 162, 166, 171

Because there are an even number of values in the data set, find the two middle numbers, add them together and then divide by 2:

Median = ( 149 + 152 ) /2

Median = 150.5

The first 6 in the number is in the thousands place (6,000), and the second 6 is in the hundreds place (600). 
The first 6 is 10 times greater than the second one.

A toy company spends $20 for every doll it makes. Promotion of the dolls costs $400 and the company sells each doll for $30. How
marissa [1.9K]

Since the company spends 20$ on each doll and sells each for 30$ thats a 10$ profit.

If the company spends 400$ on promotion it would take 40 dolls since

400$ / 10$(amount of profit per doll) = 40

so to make the promotion back it would be 40 dolls but the question was to make PROFIT so it must be 41 dolls

Colt1911 [192]

Answer:

  • 2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

Step-by-step explanation:

  • <em>Easy way to take one of the vertices and apply the transformations</em>

1. Rotate the triangle 90º counterclockwise about the origin and then translate it 10 units left and 9 units down.

  • False

2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

  • True
  • (-3, 3) →  (3, 3) → (3 - 10, 3 - 9) = (-7, -6)

3. Rotate the triangle 90º counterclockwise about the origin then translate it 1 unit up.

  • False

4. Rotate the triangle 90º clockwise about the origin then translate it 1 unit up.

I need help with these.
sattari [20]

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

6.

26/13 = x/12

2 = x/12

x = 24
