Answer:

132 people bought balcony seats and 450 people bought ground seats.

Step-by-step explanation:

We want to solve the system of equations:

\left\{        \begin{array}{ll}            15b+10g=6480 \\            b+g=582        \end{array}    \right

We can solve this by using substitution. From the second equation, we can subtract <em>b</em> from both sides:

g=582-b

In the first equation, we can divide both sides by five:

3b+2g=1296

Substitute:

3b+2(582-b)=1296

Distribute:

3b+1164-2b=1296

Simplify:

b+1164=1296

Solve for <em>b: </em>

<em />b=132<em />

<em />

Using the modified equation again, substitute:

g=582-(132)

Evaluate:

g=450

Therefore, 132 people bought balcony seats and 450 people bought ground seats.

Answer:

6. \displaystyle \frac{33}{56} ≈ 0,5892857142... = tan\:B

5. \displaystyle \frac{56}{65} ≈ 0,8615384615... = cos\:B

4. \displaystyle \frac{33}{65} ≈ 0,5076923076... = sin\:B

3. \displaystyle 1\frac{23}{33} ≈ 1,696969... = tan\:A

2. \displaystyle \frac{33}{65} ≈ 0,5076923076... = cos\:A

1. \displaystyle \frac{56}{65} ≈ 0,8615384615... = sin\:A

Explanation:

\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ

Identify the surface area of the composite figure to the nearest tenth.
BlackZzzverrR [31]

Answer:

A: 1779.2 cm^2

Step-by-step explanation:

Oh boy. Okay so the surface area of the cube.

14x14 is 116 cm.

Multiply 116 by 6 (because there are 6 square sides) which gives you 696 cm

For the can shape: (Cylinder lol)

The radius of the circular sides is 6.

Area of a circle is pi(r)^2

pi(6)^6

=18.8^2

=353.44 cm

multiply by 2 because there are 2 sides

353.44 x 2= 706.88 cm

add that to 696

=1402.88 cm

FINALLY: the last part. We need the circumference and the height of the cylinder.

We know that the height is 10 cm.

Use the circumference equation and we see that is is 37.69 cm

multiply by 10

376.9 cm

Add to the rest

1779.2 cm^2

Have a nice day. Im gonna go rest my brain L /\/\ /\ O

What are the domain and range of f(x)=logx-5
Deffense [45]

Hello and Good Morning/Afternoon:

<u>Let's take this problem step-by-step</u>:

<u>Let's define some terms</u>:

  • Domain: the set of inputs in the function (<em>in this case, it is x)</em>
  • Range: the set of all of the possible outputs (in this case, it is y)

<u>Let's find the domain:</u>

   For log(x),

           ⇒ the only inputs that are accepted are nonnegative and nonzero

               ⇒ therefore: Domain is (0, ∞)

<u>Now let's find out the range</u>:

    The biggest constraint of the output is log(x)

         ⇒ however log(x) has a range of (-∞,∞)

             ⇒ therefore the entire equation's range is

                      (-∞,∞)

<u>Answer:</u>

  • <u>Domain: (0,∞)</u>
  • <u>Range: (-∞,∞)</u>

Hope that helps!
