Dimensions of a building are 345 feet by 295 feet. if 1 inch represents 42 feet, what are the dimensions of the building on the drawing? tell me how to solve this. you : )

The dimensions of a building on the drawing are

Step-by-step explanation:

we know that

The scale of the drawing is

That means --->1 inch in the drawing represent 42 feet in the actual

so

using proportion

Part a) Find out the dimension of a building on the drawing if the dimension on the actual is 345 ft

Convert to mixed number

Part b) Find out the dimension of a building on the drawing if the dimension on the actual is 295 ft

Convert to mixed number

therefore

The dimensions of a building on the drawing are

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.
