Answer:
10
Step-by-step explanation:
We will use trigonometry to solve this problem.
We see that the side provided is the hypotenuse and the side we are looking for is opposite to the angle provided. Thus, we will use sin since sin uses opposite/hypotenuse.
Now we solve.
sin45 = x/14
sin45 * 14 = x
x = 9.899494936611665

Answer:
a. it has no solution
b. you can only substitute by making either the 'x' or 'y' the subject of either of the two equations.
Step-by-step explanation:
3x - 9y = -13.............. eqn 1
x - 3y = -7................... eqn 2
from eqn 2
x - 3y = -7, substitute by making 'x' the subject
x = -7 + 3y.................. eqn 3
put eqn 3 into eqn 1
3x - 9y = -13
3( -7 + 3y) - 9y = -13
-21 + 9y - 9y = -13
9y - 9y = -13 + 21
0 = 8, which is not possible.

Answer:
$1.475 is the average amount of snack sales per ticket sold.
Step-by-step explanation:
We are given the following in the question:
Number of popcorn bags sold = 3
Cost of a popcorn bag = $2.25
Total cost of popcorn bag = 
= $6.75
Number of soda sold = 4
Cost of a soda = $1.50
Total cost of soda = 
= $6.00
Number of candy bars sold = 2
Cost of a candy bar = $1.00
Total cost of candy bars = 
= $2.00
Total sales =
Total cost of popcorn + Total cost of soda + Total cost of candy bar
Average amount of snack sales per ticket sold =
Thus, $1.475 is the average amount of snack sales per ticket sold.
