Answer:
A. 10
Step-by-step explanation:
I found a website that explains that you need 8.3 grams of coffee to make one 5-fl oz cup of coffee.
To make 600 cups, you need 600 * 8.3 g = 4980 g
Now we convert 4980 g to lb.
1 lb = 454 g
4980 g * (1 lb)/(454 g) = 11 lb
The closest answer is A. 10
Answer: A. 10
Answer:
Kenyan French Roast coffee x=6
Sumatran coffee y=14
Step-by-step explanation:
x+y=20 blend coffee
8x+7y=7.3(20) selling price
x+y=20 ⇒ x=20-y
substitute in the equation:
8x+7y=7.3(20)
8(20-y)+7y=7.3(20) for 20 pound blend
160-8y+7y=146
-y=146-160
y=14 pond
x+y=20
x=20-14=6
check : 14*7+6(8)=146/7.3=20 pound
Answer:
The system has an infinite set of solutions 
Step-by-step explanation:
From the first equation:




Replacing on the second equation:




This means that the system has an infinite number of solutions, considering:



The system has an infinite set of solutions 
700% increase.
Step-by-step explanation:
The duration was 3 decades, or 30 years. The population starts at 100%, then doubles to 200% (decade 1), then 400% (decade 2), then 800% (decade 3).
800% - 100% = 700%
Answer:
