You are installing new carpeting in a family room. The room is rectangular with dimensions 20 1/2 feet × 13 1/8 feet. You intend

disa [49]

Answer: 1. When you estimate, it is not an exact measurement. 3ft 8 in gets rounded to 4ft and 12 ft 3 in rounds to 12ft. now find the perimeter. P=2l+2w P= 2*12 +2*4 P=32feet

2. 3ft 8in = 3 8/12 or reduced to 3 2/3 12ft 3in = 12 3/12 or reduced to 12 1/4 The fractional part is referring to a fraction of a foot.

3. The perimeter of the room is P=2l+2w or P=2(12 1/4) + 2(3 2/3) p=24 1/2 + 7 1/3 P= 31 5/6 feet

4. The estimate and the actual are very close. They are 1/6 of a foot apart.

5a. Total baseboard 31 5/6ft - 2 1/4 ft = 29 7/12 feet needed.

5b. Take the total and divide it by 8ft = 29 7/12 divided by 8= 3.7 You are not buying a fraction of a board so you would need 4 boards.

SECTION OFFor the following figure, complete the statement for the specified points.Points Q, B, and C arecollinearcoplanarboth

olasank [31]

from given figure, we obtain that the points R, T and B are on the same line, that is, on the edge of the rectangular pyramid.

So these points are collinear.

Also all these points on the same plane. Therefore, the points R, T and B are collinear and coplanar.

The third option is the correct answer

3m -9n = 24; n = - 1,1,3

Ghella [55]

given that

3m -9n =24

when n= -1

substitute it in the equation

thus

3m -9(-1)=24

solving for m

3m +9 =24

3m =24-9

3m=15

dividing through by 3

3m/3 =15/3

m =5 . thus when n= -1 , m=5

also put n=1 into the equation

3m -9(1) =24

3m -9 =24

3m= 24+9

3m =33

dividing through by 3

3m/3 = 33/3

m=11

thus when n= 1, m=11

lastly, put n= 3 into the equation

3m -9(3) =24

3m -27 = 24

3m = 24+27

3m =51

dividing through by 3

3m/3 =51/3

m =17. Thus when n = 3 , m= 17.
