There are 4 quarts in a gallon. so 25/4 = 6.25
a cow produces about 6 gallons of milk per day
Answer: the extraction is 18.2%.
Explanation:
Let's see few definitions:
TDS = Total Dissolved Solids = solids dissolved in the brew
PE = Percent Extraction = percent of solids extracted from the dry coffee grounds
The percent extraction can be calculated by the formula:
PE = TDS × Rm
where
Rm = ratio between the mass of the brew and the mass of dry grounds
Now, you need to consider the following facts:
1) every 1g of coffee absorbs 2g of water
2) the given brew ratio is 1:15, which means that for every 1g of grounds we use 15g of water
Let's call
x = grams of coffee grounds we want to use
Therefore the mass of the brew will be:
m(brew) = water we use - water absorbed by the coffee
= 15·x - 2·x
= 13·x
Therefore,
Rm = m(brew) / x
= 13·x / x
= 13
Hence, the percent of extraction will be:
PE = <span> TDS × Rm
= 1.4 </span>× 13
= 18.2
The standard deviation is lower for each group than it is for the groups combined.
Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
x=47
