Answer:
<h2>S = 11.4</h2>
Step-by-step explanation:
To find s we use the cosine rule
That's
s² = SU² + ST² - 2(SU)(ST) cos S
From the question
SU = 5
ST = 13
S = 60°
Substituting the values into the expression we have
s² = 5² + 13² - 2(5)(13) cos 60
s² = 25 + 169 - 130cos 60
s² = 194 - 65
s² = 129
Find the square root of both sides
s= √129
s = 11.357816
We have the final answer as
<h3>s = 11.4 to the nearest tenth</h3>

If you have 1 nickle, how many quarters do you have? (3)
If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12
If you have n nickles, then you have 3n quarters so 3n = q, you have a slightly different equation.
If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents
5n + 10d + 25q = 460

Answer:
There are 801 box seats and 9612 regular seats.
explanation:
Let the number of box seats be x,
Then the regular seats is 12x
The sum of seats equals to 10,413
<u>Solve:</u>
12x + x ➙ 10,413
13x ➙ 10413
x ➙ 801
There are 801 box seats.
<u>Find for regular seats:</u>
➙ 12(x)
➙ 12(801)
➙ 9612
There are 9612 regular seats.
