Mrs gray bought some eggs. She boiled one half of them and poached one fourth of the remainder . she had 9 eggs left. How many e
Scorpion4ik [409]
To answer this item, we let x be the number of eggs in the beginning. The first half of the egg which were not boiled is represented through the equation is represented by x/2.

Next, the remainder of the egg which were not boiled nor poached is equal to 
             = (1/2)(3/4)x

Simplifying,
                 0.375x

Equating this to 9,
               0.375x = 9

The value of x from the equation is 24.

Answer: 24 eggs

Hillary rolls 2 number cubes numbered 1 through 6 while playing her favorite board game. She will get a second turn if she rolls
Nataly [62]

Answer:

1 in 18

Step-by-step explanation:

The highest possible number Hillary can get is 12, meaning that the only odd number above 10 which she can get is 11.

There are two possible ways in which Hillary can get 11:

(a) Hillary rolls a 5 on her first cube and a 6 on her second cube

(b) Hillary rolls a 6 on her first cube and a 5 on her second cube

There are 34 other possible outcomes which Hillary can have when rolling her number cubes, for a total of 36 possible outcomes.

Since 2 of these outcomes result in a roll of 11, Hillary has a 2 in 36 chance of rolling an 11, which can be simplified as 1 in 18.

IrinaVladis [17]

Answer:

\boxed{\sf 319:3388}

Step-by-step explanation:

Total number of tickets sold = 3388

Total number of coach tickets = 3069

Total number of first-class tickets = Total number of tickets sold - Total number of coach tickets

= 3388 - 3069

= 319

\therefore

Ratio of the number of first-class tickets to the total number of tickets = 319:3388
