An artist is making a mural by reproducing a painting at a different scale. The original painting is 10 1/2 inches long and 4 inches wide. The mural will cover an entire wall that is 42 feet long and 16 feet wide. What will be the scale that relates the original painting to the mural?

1 inch : 4 feet

Step-by-step explanation:

Size of the Mural is 42 feet long and 16 feet.

The original painting is 10½ inches long and 4 inches wide.

On the length

Length of Painting: Length of Mural

10½ inches: 42 feet

1 inch : 42/10½ feet

1 inch : 4 feet

On the Width

Width of Painting: Width of Mural

4 inch: 16 feet

1 inch : 16/4 feet

1 inch : 4 feet

The Scale of the Original Painting to the Mural is therefore:

1 inch : 4 feet

the answer is a

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.
