(30 points) what is the value of the expression. 2.6 * 10^9 over 1.3 * 10^2? 1.3 × 10^7 2.0 × 10^7 1.3 × 10^11 2.0 × 10^11

2.0 × 10^7

2.6 × 10^9 = 26,000,000,000

1.3 × 10^2 = 130

26,000,000,000 ÷ 130 = 20,000,000

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.
