Facts:
- tub has 1400 gallons
- draining at 27 gallons/minute
How much water will be left after 18 minutes?
We know that after 1 minute, there will be 27 gallons less.
So after 18 minutes, there must be 18 times less water.
27 x 18 = 486
This is how much water was lost in 18 min
So to find out how much he had left after <u>486 is subtracted.</u>
Therefore, the answer is A) -486 gallons
Answer: What is the easiest way to find the volume of a sphere?
Image result for How to find volume of sphere explain step by step
To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.

Step-by-step explanation:
The collector has 160 movie posters and 120 band posters.
She wants to sell 24 movie posters but still have her poster collection maintain the same ratio of 160:120.
Total ratio = 160 + 120 = 280
If she sells 24 movie posters, it means
24 = 160/280 × x = 160x/280
Where x = total number of movie posters and band posters sold
24 × 280 = 160x
160x = 6720
x = 6720/160 =42
Number of band posters that she should sell = total number of both posters - number of movie posters.
Number of band posters that she should sell = 42-24 =18
12x + 14 = 26x + 21x = 27x
