Answer:
k = 5
Step-by-step explanation:
Since the quantities are in direct proportion then the equation relating them is
y = kx ← k is the constant of proportion
The y- axis is number of cups and x- axis is pounds of sugar
To find k use any of the 5 points highlighted on the graph
Using (8, 40 ), then
40 = 8k ( divide both sides by 8 )
5 = k
The answer is b because you can divide them by 2 to get the answer<span />
Answer: A
Step-by-step explanation:
The change in the y coordinates is 0, but the change in the x coordinates is 8.
Linear dimensions will be in the ratio
12/18 = 2/3
areas (all of them) will have the ratio
4/9
volumes will have the ratio 8/27
.15 * 8= 1.20
.15 * 1/5= .03
1.20 + 0.03= 1.23
Answer: 8.2
