Answer:

$650

Step-by-step explanation:

The for simple interest is

 I = Prt     Divide each side by rt

P = I/(rt)

  = 87.75/(0.045 × 3)

  = $650

Do you prefer Thai food or chinese food. is the question baised
Ksenya-84 [330]
No, this would not be a biased question unless the people asked were all Thai people or all Chinese people. Then the information would be skewed because naturally, Chinese people would favor Chinese food and same for Thai.

I need help ASAP!!!!!!!!

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
