Answer:
A and C are proportional relationships.
Step-by-step explanation:
Recall that a "proportional relationship" has no constant term. Thus, we eliminate Answers B and D immediately.
Answer A represents a proportional relationship: y varies directly with the square of x.
Answer C also represents a proportional relationship: y varies directly with x.
I’m not sure what that is
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
<u>Answer:</u>
y = 94.5 cups
<u>Step-by-step explanation:</u>
Let's say:
- y = oats
- x = chocolate chips = 212
=> Full Recipe = 212 + y
=> 2(Full Recipe) = 2(212 + y) = 613 cups
=> 2(Full Recipe) = 424 + 2y = 613 cups
=> 2y = 613 - 424
=> 2y = 189
=> y = 94.5
Therefore, the required oats to do double the recipe is 94.5 cups.
Hoped this helped.
