I did the same thing you did ... I added up the "scores" column
and divided the total by 5 .  That answer is 2 .

Then I read what you said about the answer sheet, so I went back
and looked at the problem again.<em />  Good thing I did.  You have to look
and see what the first column says, and what it means.

There are FIVE different students who each scored 4.
There are THREE different students who each scored 3.
There are FOUR different students who each scored 2.
.
.
etc.

The total of all the scores is 44, not 10.
The  total number of students is 20, not 5.

That's where the "2.2" comes from.

A circle with radius of 1 cm sits inside a 3 cm x 4 cm rectangle.
White raven [17]

The area of shaded-region is 8.86 cm^2

Step-by-step explanation:

We can see that there is a circle and a triangle in the given figure

In order too find the area of shaded region, we have to find the area of rectangle and circle first. The area of the shaded region will be obtained by subtracting the area of circle from the area of rectangle.

So,

<u>Area of circle:</u>

Radius = r = 1 cm

So,

A_c = \pi r^2\\= 3.14 * (1)^2\\= 3.14*1\\= 3.14\ cm^2

<u>Area of rectangle:</u>

Length of rectangle = l = 4 cm

Width of rectangle = w = 3 cm

So,

A_r = l*w\\= 4 *3\\=12 cm^2

Now,

Area\ of\ shaded-region = A_r - A_c\\= 12 - 3.14\\=8.86\ cm^2

The area of shaded-region is 8.86 cm^2

Need help!! I have no clue
slega [8]

Answer:

41 over 24

Step-by-step explanation:

7 2/3 can be "translated" into 3 times 7 plus 2 which is 22, so now it's 22 over 3.

5 5/8 can be "translated" into 8 times 5 plus five is forty five, so now it's 45 over 8.

We now need a common denominator.

Multiples of 8: 8, 16, 24, 32

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24

24 are both multiples of 8 and 3.

Now you have to multiply 22 and 8 because 3 times 8 equals 24 and so you have to do it to the numerator.

22*8=176

Now you have to multiply 45 and 3 since 8 times 3 equals 24 and so you have to do it to the numerator, too.

45*3=135

All you have to do now is subtract 176 from 135 which is 41
