The club sold 120 student tickets and 30 adult tickets.

Step-by-step explanation:

The cost of student ticket= $12

The cost of adult ticket= $20

The total cost of 150 tickets sold= $2040

Check for which option gives you the answer as $2040

Option A)

The cost of 30 students= 30*12= $360

The cost of 120 adults= 120*20= $2400

The total cost of 150 tickets= 360+2400= $2760 (exceeds 2040)

Option B)

The cost of 120 students= 120*12= $1440

The cost of 30 adults= 30*20= $600

The total cost of 150 tickets= 1440+600= $2040 (correct answer)

Option C)

The cost of 100 students= 100*12= $1200

The cost of 50 adults= 50*20= $1000

The total cost of 150 tickets= 1200+1000= $2200 (exceeds 2040)

Option D)

The cost of 50 students= 50*12= $600

The cost of 100 adults= 100*20= $2000

The total cost of 150 tickets= 600+2000= $2600 (exceeds 2040)

13. How many distinct 4-letter groupings can be made with the letters from the word champion if letters may not be repeated?

ddd [48]

Answer:

N = 1680

Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'

Step-by-step explanation:

Given the word 'champion' which is an 8 distinct Letter word. The number of 4 letter groupings that could be formed from it can be given by the permutation since in this case order of letters are important.

The number of distinct 4 letter groupings can be given as;

N = nPr = 8!/(8-4)!, where n= 8 and r = 4

N = 8P4 = 8!/(8-4)!

N= 8!/4!

N = 1680

Therefore, 1680 '4 letter groupings' can be formed from the word 'champion'

Find the midpoint of CD. C= (7,-4) and D= (-8,-5)

ANTONII [103]

Answer:

( $-\frac{1}{2}$ , $-\frac{9}{2}$ )

Step-by-step explanation:

The equation of a midpoint is as follows:

$(\frac{x_{1} +x_{2}}{2} ,\frac{y_{1} +y_{2}}{2})$

The x-coordinate:

x1 = 7, x2 = -8

7+(-8) = -1

Divide by 2 to get the x-midpoint

-1/2

The y-coordinate

y1 = -4, y2 = -5

-4 + (-5) = -9

Divide by 2 to get the y-midpoint

-9/2

You get:

( $-\frac{1}{2}$ , $-\frac{9}{2}$ )
