Answer:
$2
Step-by-step explanation:
Total money Shania was having = $20.
After buying raffle tickets she was having a total of $6.
Thus ,
The money she spent on the raffle tickets = Money she was having initially -
Money she was having after
purchasing tickets .
= $20 - $6
= $14.
Thus She spent a total of $14 on tickets .
Now , number of tickets she bought = 7.
So, cost of each ticket = 
= 
= $2.
Thus , each ticket costs $2 for Shania.
Answer:
B
Step-by-step explanation:
an irrational number
Answer:
The answer to your question is:
cos α = 9/ 41
tan α = 40/9
Step-by-step explanation:
Data
cos α = ?
tan α = ?
sin α = 40/41
Process
sin Ф = opposite side / hypotenuse
then, if sin α = 40/41,
opposite side = 40
hypotenuse = 41
Pythagorean theorem
c² = a² + b²
41² = 40² + b²
b² = 41² - 40²
b² = 1681 - 1600
b² = 81
b = 9
adjacent side = 9
Now,
cosine Ф = adjacent side / hypotenuse
cos α = 9/ 41
tangent Ф = opposite side / adjacent side
tan α = 40/9
