Answer:

4x + 12 = 8; 4x = -4; x = -1. Therefore the four consecutive odd integers are -1, 1, 3, 5.

Answer:

<h3>             -1, 1, 3, 5</h3>

Step-by-step explanation:

k  - an integer

so:

2k+1  - an odd integer

2k+1+2 = 2k+3  - an odd integer consecutive to 2k+1

2k+3+2 = 2k+5  - next consecutive odd integer

2k+5+2 = 2k+7  - the fourth consecutive odd integer

2k+1 + 2k+3 + 2k+5 + 2k+7 = 8

               8k + 16 = 8

                    - 16      -16

                  8k = - 8

                  ÷8     ÷8

                  k = -1

2k+1 = 2(-1) + 1 = -2 + 1 = -1

2k+3 = 2(-1) + 3 = -2 + 3 = 1

2k+5 = 2(-1) + 5 = -2 + 5 = 3

2k+7 = 2(-1) + 7 = -2 + 7 = 5

Check:  -1+1+3+5 = 3+5 = 8

Find the reference angle given: t= -5π/3.
Elina [12.6K]

Answer:

The reference angle is \frac{\pi}{3}

Step-by-step explanation:

The given angle is t=-\frac{5\pi}{3}

The reference angle is the acute angle, that a given angle  makes with the x-axis.

First let us make a sketch of the given angle. <em>See diagram in attachment.</em>

Let \theta be the reference angle of  t=-\frac{5\pi}{3}


Then, from the diagram, we need to subtract \theta from -\frac{5\pi}{3} to get to -2\pi.


We can therefore write the following equation and solve for \theta.


\Rightarrow -\frac{5\pi}{3}-\theta=-2\pi


We group like terms to get,

\Rightarrow -\theta=-2\pi +\frac{5\pi}{3}

We collect LCM to get,

\Rightarrow -\theta=\frac{-6\pi+5\pi}{3}

We simplify to get,

\Rightarrow -\theta=-\frac{\pi}{3}

We divide through by -1

\theta=\frac{\pi}{3} to get,

The correct answer is D.

Aliun [14]

Answer:

17

Step-by-step explanation:

So, this is a percentage problem.

Start off by finding how many students 0.28% is:

If 100% = 5780

0.01% = 0.578                          

Now:

0.01% = 0.578

0.28% = 16.184

The exercise tells you to round for a whole person, so 16.184 turns 17

And that's the answer!

Which is true for
IceJOKER [234]

Hi!

Your answer is C.

The vertex is the point where two different rays meet, forming an angle.

It can also simply be the point where 2 straight lines simply meet.

Option A is NOT correct because a vertex is not angle, it is a <em>part </em>of an angle.

Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

See the image below for an example:
