A circle has a radius of 6. An arc in this circle has a central angle of 330
sashaice [31]

Answer: Arc\ lenght\approx34.55\ units

Step-by-step explanation:

<h3> The complete exercise is: " A circle has a radius of 6. An arc in this circle has a central angle of 330 degrees. What is the arc length?"</h3><h3></h3>

To solve this exercise you need to use the following formula to find the Arc lenght:

Arc\ lenght=2\pi r(\frac{C}{360})

Where "C" is the central angle of the arc (in degrees) and "r" is the radius.

In this case, after analize the information given in the exercise, you can identify that the radius and the central angle in degrees, are:

r=6\ units\\\\C=330

Therefore, knowing these values, you can substitute them into the formula:

Arc\ lenght=2\pi (6\ units)(\frac{330}{360})

And finally,you must evaluate in order to find the Arc lenght.

You get that this is:

Arc\ lenght=2\pi (6\ units)(\frac{11}{12})\\\\Arc\ lenght=11\pi \ units\\\\Arc\ lenght\approx34.55\ units

You go shopping and spend $264 on shirts and shorts. You purchase a total of 9 items. Each shirt costs $24 and each pair of shor
Kisachek [45]

Answer:

3 shirts, 6 shorts

Step-by-step explanation:

A total of $264 is spent during shopping on shirts and shorts

Each shirt costs $24

Each shorts cost $32

Therefore the quantity of shirts and shorts bought can be calculated as follows

24× 3= 72

32×6= 192

192+72= 264

Hence 3 shirts and 6 shorts were bought

Please help answer this
saul85 [17]

Answer:

Option D.

Step-by-step explanation:

The given inequality is y\le -2x-2.

To graph this inequality, we need to graph the corresponding linear equation;

y=-2x-2

The intercepts are (0,-2) and (-1,0).

Plot these two points and draw a solid straight line through them.

We then test the inequality with the point (0,0).

0\le -2(0)-2.

0\le -2.

This statement is false.

So we shade the lower half plane to obtain the graph in option D.

For the line segment whose endpoints are A(0,0) and B(4, 3), find the x value for the point located
Crank

Answer:

Step-by-step explanation:

The distance between A and B is given by the Pythagorean Theorem:

= \sqrt{(4-0)^{2}+(3-0)^{2}} = 5

The angle of the line segment is:

\theta = \tan^{-1}\left(\frac{3-0}{4-0} \right)\\\\\theta \approx 36.870^{\circ}

The x-coordinate of the point is:

x = 0 + \frac{2}{3}\cdot (5) \cdot \cos 36.870^{\circ}\\\\x = 2.667

x≅ 2.7
