Graham uses a 10 by 10 grid to model a decreasing pattern. he cuts off a section representing a percent of the current area so that the remaining area represents the next term in the pattern, rounded to nearest whole centimeter. the area after each cut is shown on the graph.

After each cut, the remaining area is 80% of the previous area.

Step-by-step explanation:

The original area is 100 cm^2. After the first cut the remaining area is 80 cm^2, that is, 80 cm^2/(100 cm^2)*100 = 80% of the previous. The 80% of 80 cm^2 is 0.8*80 = 64 cm^2, which is the remaining area after the second cut. The 80% of 64 cm^2 is 0.8*64 = 51.2 cm^2, which is the remaining area after the third cut. And so on.

im alright what do you need

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
