How long will it take the same crew to clear the entire plot of 2 1/2 acres?

1. 15 days

2. 0.17 acre.

Step-by-step explanation:

1. Determination of the number of days.

From the question given above,

The crew clears ⅓ acre of land in 2 days.

Therefore, the crew will clear 2½ acres in = (2½ × 2) / ⅓

= (5/2 × 2) × 3

= 15 days

Thus, the crew will clear 2½ acres in 15 days

2. Determination of the acre of land.

From the question given above,

The crew clears ⅓ acre of land in 2 days.

Therefore, the crew will clear X acre of land in 1 day i.e

X acre of land = ⅓ ÷ 2

X acre of land = ⅓ × ½

X acre of land = 1/6

X acre of land = 0.17 acre

Thus, the crew will clear 0.17 acre of land in 1 day

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.
