Answer:
C
Step-by-step explanation:
A function is a rule that assigns exactly one output to each input. This means the input values of the function cannot repeat with different output values.
Tables A, B, and D have repeating input values in the x row (the second row). This means they are NOT functions.
C is the solution.
Answer:
165 liters of 15% solution
Step-by-step explanation:
15F + 65S = 60(1650)
F + S = 1650
F = 1650-S
15(1650-S) +65S = 99000
50S = 99000-24750= 74250
S = 74250/50 = 7425/5 = 1485 liters of 65% solution
F = 1650-1485 = 165 liters of 15% solution
65 is much closer to 60 than 15 is, so you know there will be mostly 65% solution with relatively little 15%
Hope this helps, have a nice day/night! :D
Answer:
A prism whose cross-section is a 60-sided polygon has 120 vertices.
Step-by-step explanation:
A polygon has the same quantity of sides and vertices, as a prism has two poligonal faces, the number of vertices is double the quantity of vertices of the 60-sided polygon. That is:


A prism whose cross-section is a 60-sided polygon has 120 vertices.
The answer is D. 15, 36, 39.
Call chocolate 'c' and mint 'm'.
-> c=3m/5.
Since c+m= 7 (lbs)
->3m/5 + m = 7
Solve m= 35/8 ~4.4 lbs
->c= 2.6 lbs
