Answer:

  317°

Step-by-step explanation:

The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.

  (7x +1)° +90° +(9x -7)° = 180°

  16x = 96 . . . . . divide by °, subtract 84

  x = 6 . . . . . . . . divide by 16

Then angle AOD is ...

  (7·6 +1)° = 43°

Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.

  arc ACD = 317°

Canceling units is also called: a. changing the value c. multiplication b. unit analysis d. making connections
SOVA2 [1]

Canceling units is also called unit analysis.

This is also called dimensional analysis.

What is a unit of analysis in statistics?

  • The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
  • Because it is the analysis you do in your study that determines what the unit is.
  • For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.

For example -

1 ft = 12 in

3 ft =  3 ft * \frac{12 in }{1 ft}

3 ft = ( 3 * 12 )  in ⇒ 36 in

Answer:

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
