Answer:
4 gallons of water.
Step-by-step explanation:
1. There is 1 gallon of 10% solution
2. There is 2% saline in water
3. The equation is 10% of 1 gallon = 2% of solution of x gallons of water + saline
0.1 = 0.02(x + 1)
Subtracting 0.02 from both sides, we get
0.1 -0.02= 0.02x +0.02 -0.02
0.08 = 0.02x
Dividing both sides by 0.02, we get
0.08/0.02 = 0.02x/0.02
x = 4.
4. The answer is 4 gallons of water.
Hope you will understand the concept.

Answer:
Step-by-step explanation:
Find the LCM of 8,9 and 10.
Prime Factorization to find LCM,
8 = 2 × 2 × 2
9 = 3 × 3
10 = 2 × 5
LCM ( 8 , 9 , 10 ) = 2 × 2 × 2 × 3 × 3 × 5 =360
But 360 is not square
Now we make the pairs complete by multiplying same numbers in prime factorization of LCM.
We need one 2 and one 5 to complete the pair.
We get, Least Square number = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 3600
Hope this helps
good Luck
One US quart is approximately 0.95 L
Hence if your bucket has a volume of V cm^3, then it will contain V/0.95 quarts.
