9 is 12% of which number ?

Answers

Answer 1
Answer: Let x be the original number we are trying to find.

9 = 0.12x
9 =  (12)/(100)x
900 = 12x
\implies x = 75
Answer 2
Answer: In math, "is" means equal, "percent symbol" means to divide by 100, and "of" means times, or multiply.

9 = ?% x 12

Now,if ?% x 12 = 9, then 9 divided by 12 must also be ?%, just like 3 x 2 =6; and 6 divided by 3 = 2, or 6 divided by 2 = 3. So,

9 / 12 = 0.75

Toexpress as a percent, multiply by 100 and then add the % symbol, ormove the decimal 2 places to the right and then add the % symbol. 0.75becomes 75% (which when you divide by 100, you get .75 again).

9 is 75% of 12. Check your work: 9 = .75 x 12 If this is true, then your answer is correct

The specific rigid motion in the shape is translation

Explaining the idea of a rigid motion

Rigid motions, or isometries, are transformations in geometry that preserve distances and angles.

This includes

  • translations (shifting),
  • rotations (turning around a fixed point),
  • reflections (flipping over a line).

The importance of rigid motions lies in their ability to maintain the shape and size of geometric figures.

For the given figure, the rigid motion is translation
