A total of 363 were sold for the school play. They were either adult tickets or student tickets. The number of student tickets s
timurjin [86]

Answer:

The number of adult tickets sold was 121

Step-by-step explanation:

The general equation is: <em>S</em> + <em>A</em> = <em>T</em>    ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.

<em>S</em> + <em>A</em> = <em>T</em>  

2x + x = 363  

3x = 363  

x = 363 / 3

x = 121

Adult tickets: <em>A</em> = x = 121

Student tickets: <em>S</em> = 2x = 2 * 121 = 242

If ∠G measures 45°, ∠F measures 82°, and f is 7 feet, then find g using the Law of Sines. Round your answer to the nearest foot.
DIA [1.3K]

The value of g across from angle G is 5feet

According to sine rule

\frac{e}{sinE}=\frac{f}{sinF}=\frac{g}{sinG}

Given the following

∠G = 45°

∠F = 82°

f = 7feet

Required

side g

Substitute the given values into the formula

\frac{f}{sinF}=\frac{g}{sinG}\\ \frac{7}{sin82}=\frac{g}{sin45}\\\frac{7}{0.9903}=\frac{g}{0.7071}\\7.0686=\frac{g}{0.7071}\\g=7.0686*0.7071\\g=4.998\\g\approx5ft

Hence the value of g across from angle G is 5feet

If 5^n x 5^3 = 5^6, then n is _____.<br><br> A) 18<br> B) 2<br> C) 3<br> D) 9
Eddi Din [679]
<h3>Answer:  C) 3</h3>

The rule we'll use is a^b*a^c = a^(b+c). So we add the exponents.

That means 5^n*5^3 = 5^(n+3)

So 5^n*5^3 = 5^6 turns into 5^(n+3) = 5^6

The bases are equal to 5, so the exponents be equal to one another.

n+3 = 6

n+3-3 = 6-3

n = 3

So 5^3*5^3 = 5^(3+3) = 5^6.
