In a game of checkers there are 12 red pieces and 12 black game pieces.Julio is setting up the board to begin playing. what is t
Bond [772]
Since there are equal numbers of pieces, the chances of Julio getting a red on the first pull is 12/24  or 1/2 (reduced)

However on the second pull there are only 11 reds (Julio pulled one out) out of 23 remaining pieces so the chances of pulling the second red are 11/23

Now multiply those possibilities: 
 1/2  x 11/23 and you will get 11/46 which is the probability of pulling two reds in a row.  11/46 is the answer.

DochEvi [55]
<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>

=============================================

Explanation:

If you save 65%, then you pay the remaining 35%

0.35x is the final price when x is the original price

0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35

57.14 goes in the first box

--------------

This must mean 80 goes in the other box.

Here's the steps on how to get 80

If you save 75% then you pay the remaining 25%

0.25x = 20

x = 20/0.25

x = 80

80 goes in the second box

I need help with #11 - #14.
Aleonysh [2.5K]

Answer:

I can get you jump started a bit.

Step-by-step explanation:

So Each of those pairs of figures are Similar.

This means they have equal angle measures but different side lengths.

To find it, we have to make a <u>Proportion:</u>

<u>Example: #11</u>

<u />\frac{x+1}{3x+1} =\frac{8}{20}<u />

So let's solve the first one!

24x+8=20x+20\\4x=12\\x=3

Easy As Pie!

If you need more help, contact me! :)

Hope this Helps!

P.S. Stay Safe!
