You can calculate the arc lenght by using this formula: 
arc length = 2π*r*(A/360) , where A=angle of the arc. 

So for you it would be: 
arc length = 2π*4*(72/360) = 5.03

I hope that helped.

inessss [21]

Answer:

Aimee can save $24 by buying tickets at the lower price that is at the theater.

Step-by-step explanation:

First, you need to find the amount she would spent by buying tickets at the theater and online by using a rule of three:

Theater:

60→8

x  ←24

x=(60*24)/8=180

Online:

51→6

x ←24

x=(51*24)/6=204

Now, you need to calculate the difference:

$204-$180=$24

According to this, the answer is that Aimee can save $24 by buying tickets at the lower price that is at the theater.

Which graph shows a proportional relationship?
kherson [118]

Answer:

The second option

Step-by-step explanation:

The rate of change needs to stay constant.

The rate of change can be explained by looking at the "rise" (y) over the "run"(x)

The rate of change for the second option is 2.  We know this because...

Rise(2)

----------

Run(1)

Try looking at one of the points, now go up 2 and over 1, you should now be at the second point, do it again but twice, you should now be at the third point. A proportional relationship must also go through the origin (0,0)

Look at the picture and read the question. I think the answer is 137 degrees but I don't know how to get it. I need help lol. Th
slamgirl [31]

Answer:

That is a parallelogram so that opposite angles are equal.

10x -27  = 2x + 29

x = 7

and therefore those angles equal 43 degrees each

It is a parallelogram, so

angle V + W +X + Z = 360

we know that angle Y + angle W = 2 * 43 = 86 degrees

angle V + angle X = 360 -86 degrees

angle V + angle X = 274 degrees

angle V = 274 / 2 = 137 degrees
