Answer:

a. 81 square inches

b. 108 inches

Step-by-step explanation:

The area of all 5 squares combined is 405 square inches. This is 5 times the area of 1 square. 405/5 = 81. The area of 1 square is 81 square inches.

Since this is a square, the sides are equal. Thankfully the area of 1 square is a perfect square so the length of one side of the square is a full number, which is 9. All of the squares are congruent as shown in the diagram so we simply add every length together (there are 12 sides, each side is 9 inches).

12*9 = 108 and that is the perimeter.

Dana takes a sheet of paper and cuts from one corner to the opposite corner, making two triangles. If the piece of paper is 8 in
Bas_tet [7]

Answer:

9.4 inches

Step-by-step explanation:

The triangle formed is  aright angled triangle with the right angle between the  length and width of the paper cut hence the diagonal represents the hypotenuse side.

Recall that Pythagoras theorem states that

a^2 + b^2 = c^2 where c is the hypotenuse side and a, b are the opposite and adjacent sides

Hence

8^2 + 5^2 = c^2

c^2 = 64 + 25

= 89

Finding the roots of both sides

c = 9.433981132

To the nearest tenth

c = 9.4 inches

Mr. Brown is splitting his students into groups to give presentations about novels they read. He wants each group to have 4 stud
Andrei [34K]

Mr. Brown can make fewer than 6 full groups to give presentations.

<h3>Inequality</h3>

Inequality is an expression used to show the non equal comparison of two or more numbers and variables.

Let x represent how many full groups Mr. Brown can make.

He wants each group to have 4 students. There are fewer than 24 students in class today, hence:

  • 4x < 24
  • x < 6

Mr. Brown can make fewer than 6 full groups to give presentations.
