To find your change, first you must determine how much the customer is paying. To find this, you must multiply the cost of one book by the number of books bought.
$0.75 • 9 = $6.75
To find the change, you must subtract $6.75 from $20. $13.25 is your change.
An example of an equation used to solve this would be
0.75(9) + c = $20

Ten thousand raffle tickets are sold. one first prize of$2000,4 second prizes of $800 each, and10 third prizes of$400 each are t
Makovka662 [10]
From the information given:
Random wins      2000       800        400           0
Probabilities        1/10^4   4/10^4    10/10^4    9985/10^4
thus the expectation will be:
E(x)=[2000+4*800+4000+9985*0]/10^4
E(x)=9200/10000
E(x)=$0.92

Two people are 100 feet apart on opposite sides of a tree. The angles of elevation from the people to the top of the tree are 30
cricket20 [7]
We need to solve for the height of the tree given two angles and distance between the two observers. See attached drawing for a better understanding of the problem.
We derive to equations using SOH CAH TOA such as below:
sin30 = h / x
sin 45 = h / (100-x)

sin 45 (100-x) = xsin30 
70.71 - 0.71x = 0.5x
70.71 = 1.21 x
x = 58.44

Solving for h, we have:
h = xsin30
h = 58.44 sin30
h = 29.22

The height of the tree is 29.22 feet.
