Answer:

$\bold{8\pi}$ or $\bold{25.12}$

Step-by-step explanation:

We know that as shown by the diagram, the radius is 4. So in this case, we want to find the circumference of the entire circle, then just multiply by $\frac{3}{4}$ , because the radii from the intact section are perpendicular.

The circumference of a circle is just $\pi \times d$ where $d$ is the diameter of the circle. The diameter is just the radius $\times 2$ which gives us

$d = 4 \times 2 = 8$

Thus lending us $8\pi$ or $25.12$ if we substitute $\pi$ with 3.14.

1/2 of lla's workspace is covered in paper.1/3 of the paper is covered in yellow sticky notes.What fraction of lla's workspace i

Blababa [14]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

We have been given that 1/2 of Ila's work-space is covered in paper.1/3 of the paper is covered in yellow sticky notes.

First of all, we will draw a model to represent our given information as shown in the attached image.

To find the fraction of Ila's work-space that is covered in yellow sticky notes, we need to find 1/3 of 1/2 as:

$\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{2}\times \frac{1}{3}$

$\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{2\times 3}$

$\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{6}$

Therefore, $\frac{1}{6}$ of Ila's work-space is covered in yellow sticky notes.

What is -x/3 = 9. Solve for x

vlada-n [284]

Note: I just noticed that you only have one negative sign. If you mean to put -9, change the sign to positive. If not, leave the answer.

Note the equal sign. what you do to one side, you do to the other. Isolate the x. First, multiply 3 to both sides

-x/3(3) = 9(3)

-x = 9(3)

-x = 27

Next, to isolate the x, divide -1 from both sides

-x/-1 = 27/-1

x = 27/-1

x = -27

-27 is your answer for x.

hope this helps

I NEED HELP PLEASE, THANKS! :) A commercial passenger jet is flying with an airspeed of 185 miles per hour on a heading of 036°.

Sindrei [870]

We are given that the passenger's jet is flying at a speed of 185 miles per hour, with a direction of 36 degrees, and the wind speed being 47 mph with a direction of 120 degrees. From this, you could create a diagram is shown in the attachment.

[ 185 cos 36, 185 sin 36 ]

+ [ 47 cos 120, 47 sin 120 ]

_______________________

[ 185 cos 36 + 47 cos 120, 185 sin 36 + 47 sin 120 ]

√( 4263 + 33988 )^2

= ( About ) √38251 = 195.57 mph

<u><em>Solution = 195.6 mph, 069° </em></u>
