The volume of the <span>goldfish pool is V= 0.5ft x 1.5ft x 3ft=2.25 ft^3
so 7.5gallons ----------> 1 ft^3
x=? <----------- </span>2.25 ft^3
<span>x= 2.25 x 7.5 / 1= 16.87 gallons
the answer is </span>16.87 gallons of water <span>
</span>
Hope this helps you...!!!
Answer:
720 ways to arrange
Step-by-step explanation:
Use the factorial of 6 to find this solution. Namely, 6!
This means 6*5*4*3*2*1 which equals 720
It seems like a huge number, right? But think of it like this: For the first option, you have 6 collars. After you fill the first spot with one of the 6, you have 5 left that will fill the second spot. After the first 2 spots are filled and you used 2 of the 6 collars, there are 4 possibilities that can fill the next spot, etc.
Answer:
The probability of that happening is 1/22
Step-by-step explanation:
In order to find the probability, you need to start by finding the probability for each step. The probability of the first one being red is the number of red marbles divided by the total number of marbles.
3 red / 12 total.
3/12
1/4
Now the chance that the second is white is the total number of white marbles divided by how many are left in the bag.
4 white / 11 left
4/11
Lastly, the chance of the last one being blue is the number of blue marbles divided by the amount of total marbles left after two pulls.
5 blue/ 10 left
5/10
1/2
Now to find the overall probability of all 3 happening, we multiply all 3 probabilities together.
1/4 * 4/11 * 1/2 = 1/22
