Answers

Answer 1
Answer: [tex]4r^{2} =64r^{2} =16r= \sqrt{16} = ±4
Answer 2
Answer: 4r² - 5 = 59
     + 5  + 5
     4r² = 64
      4       4
       r² = 16
       r = +4

The answer to the problem is equal to +4

A teacher wants to arrange 16 chairs in equal rows in his classroom. How can he arrange the chairs? () in 4 rows, with 20 chairs in each row () in 2 rows, with 8 chairs in each row » In Brows, with 8 chairs in each row () in 3 rows, with 5 chairs in each row My Progress Sign out​

Answers

The possible arrangement can be done as -

  • 2 rows, with 8 chairs in each row.
  • 4 rows, with 4 chairs in each row.
  • 8 rows, with 2 chairs in each row.

What is a Arrangement? What is equation modelling? What is a mathematical equation and expression?

  • Arrangement numbers, more commonly called permutation numbers, or simply permutations, are the number of ways that a number of things can be ordered or arranged.
  • Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions.

Given is that a teacher wants to arrange 16 chairs in equal rows in his classroom.

The possible arrangement can be done as -

  • 2 rows, with 8 chairs in each row.
  • 4 rows, with 4 chairs in each row.
  • 8 rows, with 2 chairs in each row.

Therefore, the possible arrangement can be done as -

  • 2 rows, with 8 chairs in each row.
  • 4 rows, with 4 chairs in each row.
  • 8 rows, with 2 chairs in each row.
