1. Rotate segment C D 180° around point D.
Yuliya22 [10]

Rotating CD 180 degrees around the point D would mean rotating it to the other side of D, in other words, rotating it clockwise. The new line would be D->M->C

Rotating CD 180 degrees around the point E would mean rotating it clockwise till "E" is a point of the line. The new line would be E->M->D.

Rotating CD 180 degrees would keep the line in the same position right now but with CD being in different order. The new line would be D->M->C.

Best of Luck!

A tablecloth has a length of
bearhunter [10]

Answer:

45/64 m²

Step-by-step explanation:

We are given the length and width of the tablecloth (breath = width).

  • Length = 9/8 m
  • Width = 5/8 m

We know that the formula for the area of a rectangle is A = L × W.

Assuming the tablecloth is in the shape of a rectangle (since the problem gives us length and width), we can substitute the length and width into the formula.

  • A = 9/8 × 5/8
  • A = 45/64

The area of the tablecloth is 45/64 m².

Fittoniya [83]

Answer:

2000

Step-by-step explanation:

A(m) = 100 + 0.20m

B(m) = 80 + 0.3m

For company A to have a better deal, the truck must be driven more than __ miles per day.

Solve::

100 + 0.2m < 80 + 0.3m

-------

20 < 0.1m

m > 2000/1 = 2000 miles

---------------

2500 mi
