Answer:

The answer is B.

Step-by-step explanation:

We want 1/6 of 144, so we divide 144/6=24 students.

Then, only 2/3 of those 24 students will make it to the final round. So, we want to know how many students are in three (2/<u>3</u>) groups and we want two (<u>2</u>/3) of those groups. So, we divide those 24 students by 3 to know each group has 8 students and then we want 2 of those groups (remember <u>2</u>/3), so we multiply 2x8=16 students in the final round.

What is the angle of rotation counterclockwise about the spinner's center that maps label g to label B?
gizmo_the_mogwai [7]

Answer:

The answer is:

The angle of rotation counterclockwise about the spinner's center that maps label g to label B is 180° .

Step-by-step explanation:

The angle of rotation counterclockwise about the spinner's center that maps label g to label B is 180° .

Look at the attached picture of a spinner:

We know that the angle formed by a straight line is  equal to 180°

So, in order to map label g to label B we have to set the needle of the spinner straight. Hence the angle formed by the needle is 180° ....

Answer:

  • 66.56 cm

Step-by-step explanation:

<u>The figure consist of:</u>

  • 1. A rectangle with sides 10 cm and 17 cm
  • 2. A quarter circle

<u>The perimeter is:</u>

  • P = 1/4C + 2*10 + 17 + (17 - 8) + 8
  • P = 1/4*2*3.14*8 + 54 = 66.56 cm

The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is ___ square units. (Input w
vekshin1
You have the polygon MNOPQR which can be expressed as two rectangles pasted one next to each other.

To see the two rectangles in the picture, you can draw a line parallel to segment MR througn point N.

From the original picture you can state the dimensions of both rectangles.

Call S, the point where the line that you drew intercepts the segment RQ.

Then one rectangle is MNSR and the other rectangle is OPQS.

The measures of the sides of the rectangle MNSR are:

- the length of MN = length of SR = base

- the length of MR = the length of NS.= height

So its area is base * height, which you can all A1.

The measured of the rectangle OPQS are:

- segment OP = segment SQ = segment QR - segment SR = base

- segment PQ = segment OS = height

So its area is base * height, which you can call A2.

Then the area of the polygon MNOPQRS is A1 + A2. One of them is 9 u^2 and the other is what the answer is asking for, and that you have calculated above.

With this procedure you can tell the value needed.
