Answer:

  b. Subtracting the base period amount from the analysis period amount, dividing the result by the base period amount, then multiplying that amount by 100%

Step-by-step explanation:

A percentage change can be computed from ...

  ((new amount) -(old amount))/(old amount) × 100%

This best matches the description of choice B.

_____

<em>Comment on the answer</em>

The formula offered in the question will show the "percent change" from 100 to 103 as 3. It is not 3; rather, it is 3%. The final multiplication must be by 100% in order to arrive at the proper number.

Answer:

Sum=720  x=105 degrees  Angle H=110 degrees   Angle I= 100 degrees   Angle K= 135

Step-by-step explanation:

*A hexagons angles add up to 720

*This is a hexagon

*No matter  how the hexagon is shaped, it's still going to add up to 720

  1. Combine all of the angles (known and unknown) into an equation to equal 720
  2. 140+105+(x+30)+130+(x-5)+(x+5)=720
  3. remove parentheses
  4. 140+105+x+30+130+x-5+x+5=720
  5. Combine like terms and simplify
  6. 3x+405=720
  7. subtract 405 from both sides
  8. 3x=315
  9. divide by 3 on both sides
  10. 3x/3=315/3
  11. x=105
  12. Angle H = x+5
  13. Plug in x
  14. 105+5=110
  15. Angle H= 110 degrees
  16. Angle I = x-5
  17. pug in x
  18. 105-5=100
  19. Angle I= 100 degrees
  20. Angle K= x+30
  21. plug in x
  22. 105+30=135
  23. Angle K= 135 degrees

Explain the relationship between the area and the radius of a circle.
Bess [88]

Area of a Circle: The area of a circle is the amount of space the circle takes up. To compute the area of a circle, we use the formula a=πr^2 where r is the radius of the circle.

Radius: The radius of a circle is the distance from the center of the circle to any point on the circle.
