You are using a sturdy building material to design a water fountain basin for a park in the city. The bottom and sides of the ba
sin should be 1 foot thick. Its outer length should be twice its outer width an outer height. Let x represent the outer height and outer width.
1. Use the interior length, interior width, interior height, and the volume to write a polynomial equation that represents the situation.
2. Write the polynomial equation in standard form.
3. Factor the polynomial equation and solve for x.
4. Determine the lengths of the basin.

Given:
Total number of cubes = 40
Red cubes = 18
Blue cubes = 13
Yellow cubes = 9
Aysha adds some more red cubes into the bag.
The probability now that she will take a red cube is 0.5.
To find:
The probability that she will take a yellow cube.
Solution:
Let Aysha adds x red cubes into the bag. Then,
Number of total cubes = 40+x
Number of red cubes = 18+x
Probability of getting a red cube is:
The probability now that she will take a red cube is 0.5. So,
Divide both sides by 0.5.
It means Aysha adds 4 more red cubes into the bag.
Now, the total number of cubes int he bag is:
Probability of getting a yellow cube is:
Therefore, the required probability is .
