Answer:
Let's say someone is selling lemonade at a lemonade stand. The more cups of lemonade this person sells, the more money they get. If 1 cup= $1, then he would get $2 for 2 cups.
Step-by-step explanation:
The price of the lemonade cup and the lemonade cup are a constant of proportionality. They are proportional to each other. The more lemonade you sell, the more money you get.
The graph would be a straight diagonal line. The y would be the money, and the x would be the amount of lemonade sold. Since they are the same and proportional, they would go in a straight line.
Answer:
B
Step-by-step explanation:
The number 
is 8 times greater than 
thus, 
multiply both sides by 
we get 
if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8
then B is the answer
Step-by-step explanation:
but ... you had already correctly answered the first part.
L² + W² = d²
Pythagoras ...
all you needed to do now was do the calculations. no "brainware" needed ...
30² + 10² = d²
900 + 100 = d²
1000 = d²
d = 31.6227766... ≈ 31.6 units
