Answer:
150 oz.
Step-by-step explanation:
There are already 150 ounces of alloy of nickel.
Of this 150 oz, 70% is pure i.e. nickel content = 150(0.7) = 105 oz
Now available is
Nickel Other metals
105 45
Let x oz of pure nickel is added.
Then new alloy will have 105+x oz nickel in total of 150+x oz.
Percentage pure = 
Simplify to get
Hence answer is 150 oz should be added.
Answer:
A. Sam, Joe, Lynn, Kori
B. Kori, Lynn, Sam, Joe
Step-by-step explanation:
We need Kori and Lynn together and Kori and Sam at least a seat apart.
A. Sam, Joe, Lynn, Kori
B. Kori, Lynn, Sam, Joe
C. Lynn, Kori, Sam, Joe
D. Responses A and C
It seems both A. Sam, Joe, Lynn, Kori and B. Kori, Lynn, Sam, Joe both work. There is no choice for both of them so I'll just put both of them as my answer.
The answer to your question is A
You would be 3ft above the sea level, if you are -6ft under the sea level and if you are standing 3ft “above” you would have to clime back up 9ft to get back to the positive’s which is “positive 3” so yes, your elevation will be opposite of the “plain” since you went to a -6 to a positive 3, with different numbers.
Answer:
54
Step-by-step explanation:
Estimate=Population size × Sample proportion
population size = 120
sample proportion = (9)/(9+6+5) = 9/20 (check on Cymath as a resource)
estimate = 120 x 9/20 = 54
