To find equivalent numbers you multiply the top and bottom by the same number. Examples are: 2/10 (by 2), 3/15 (by 3), 4/20 (by 4), etc.

1 * 9 = 9
------------
5 * 9 = 45

So another is 9/45

hope it helps!

How do you solve for the area for a complex figure
Dmitriy789 [7]

Step-by-step explanation:

It varies depending on the structure of the figure your taling about. If it is a bunch of squares or rectangles, you get the perimeter of all sides and then you try to make the figure into smaller squares or rectangles. After that now find the perimeter of the new side (opposit side should tell you) and then find the area for all the rectangles and squares. After that step, you add all the areas together and...viola!!!! You get the area of the complex figure. If it is not a rectangle please comment with the object and I could help you.

a radioactive sample contains 3.00 g of pure 11c, which has a half-life of 20.4 min. (a) how many moles of 11c are present initi
sveta [45]

The number of mole of pure 11C (carbon-11) initially present is 0.2727 mole

<h3>Description of mole </h3>

The mole of a substance is related to it's mass and molar mass according to the following equation

Mole = mass / molar mass

With the above formula, we can obtain the number of mole of pure 11C. Detail below:

<h3>How to determine the mole of 11C</h3>

From the question given, the following data were obtained:

  • Molar mass of 11C = 11 g/mol
  • Mass of 11C = 3 g
  • Mole of 11C =?

Mole = mass / molar mass

Mole = 3 / 11

Mole = 0.2727 mole

Therefore, the number of mole of pure 11C initially present is 0.2727 mole

You need 3/4 yard of ribbon for one gift box. You have 3 yards of ribbon. How many gift boxes do you have ribbon for
Kazeer [188]

Answer:

4

Step-by-step explanation:

You take 3/4 + 3/4 and add it. That equals 1.5, so you take 3/4+ 3/4 again and you get 1.5 . So, 1.5+1.5 is 3. So that's how you get your total of 4 boxes.
