Use volume displacement to determine the volume of this metal sample to the nearest 0.1 ml.
umka21 [38]
The volume displacement method is a manifestation of Archimedes' Principle. This principle states that the volume of the object placed on a known volume of water, is equal to the volume of water displaced. Actually, it could just be any liquid. Thus, whatever the displaced volume is, that is equivalent to the volume of the metal sample. I can't give an exact answer because there is no given information. But the concept works that way.

18/13=3/4x<br> what does x equal?
sveta [45]

Answer:

x = 24/13

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

18/13 = 3/4x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide both sides by 3/4:          x = 24/13

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    18/13 = 3/4(24/13)
  2. Multiply:                        18/13 = 18/13

Please help i need help on question b
anzhelika [568]

There are 12 possible outcomes.....three of these will be a "7"  ...so...

A "7" should occur  1/4 of the time

If each player pays 20p to play.....the school  will take in  120 * 20  = 2400p

However.......1/4 of the players should win =  30 players.....and each lollipop costs 30p.....so......the school should spend 30 * 30  = 900p for the prizes

So......the school should raise   2400 - 900 = 1500p  if 120 people play the game

Help!!! Will give brainliest to correct answer.....
zlopas [31]
I believe the answer is C.

93.53 - 21.41 = 72.12

If you simplify C, its answer becomes equivalent to the answer of the original problem:

(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)

70 + 2 + 0.1 + 0.02

72.12
