Let's find out many more students in the survey prefer math over science?
MATH
=> 80 students * 0.55  = 44 students love math.
SCIENCE
=> 80 * .15 = 12 students love science
=> 44 - 12 = 32 students

B. 32

What is 9% as a decimal

Answers

It can be helpful to realize the the "%" symbol is a shorthand way to write "/100". That is 9% means exactly 9/100. Of course, you know that hundredths are written in the second decimal place, so

... 9% = 9/100 = 0.09
0.09 Move the decimal point over two digits to account for the x100

Name all polygons shapes

Answers

Polygons are closed plane figures with straight sides. Here are some examples of polygon shapes:

  • Triangle (3 sides)
  • Quadrilateral (4 sides)
  • Pentagon (5 sides)
  • Hexagon (6 sides)
  • Heptagon (7 sides)
  • Octagon (8 sides)

What are polygons

Polygons are two-dimensional, closed geometric shapes with straight sides. These shapes are formed by connecting a sequence of line segments end-to-end to create a closed figure.

Other polygons are:

  • Nonagon (9 sides)
  • Decagon (10 sides)
  • Undecagon (11 sides)
  • Dodecagon (12 sides)

The study of polygons is an essential part of geometry and lays the foundation for understanding various geometric properties and concepts.
