One package of tile will cover 3 square feet.How many packages will shee need 8,13,15,39
IrinaVladis [17]

Hey there! :)

Answer:

13 packages.

Step-by-step explanation:

Begin by finding the total area of this composite figure. Separate the figure into separate rectangles. Use the formula A = l × w to calculate the area of each:

Smaller rectangle:

Subtract 7 from 9 to find the width:

9 -7 = 2. Therefore:

2 × 2 = 4 ft².

Larger rectangle:

7 × 5 = 35 ft².

Add up the two areas to find the area of the entire figure:

4 + 35 = 39 ft².

If each package of tile covers 3 ft², simply divide to find the package of tiles needed:

39 / 3 = 13 packages.

What is 6 divided by a number that will give you 12
AURORKA [14]

  ▶︎◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◀︎

Hello There!

We need to find what number, if 6 is divided by it, gives us 12.

This isn't hard, I promise! I am going to take you through a few steps, and we'll find the answer.

Are you ready? Then let's begin...:)

Procedure:

  ✦ We can think about it as: 6 divided by what number gives us 12?

(let the number be z)

^6/_z=12

Multiply both sides by z

6=12z

Divide both sides by z

z=^6/_{12}

Which is the same as

z=^1/_2

  • hope it's helpful!
  • wishing you a great day!

Greetings!
