1-in. length on the blueprint corresponds to an actual length of 3 ft. what is the scale of the blueprint? what are the actual dimensions of the bathroom? what is the actual area of the bathroom?

1 in. : 5 ft, 17.5 ft by 20 ft, 350 ft2

1 in. : 3 ft, 4.5 ft by 9 ft, 40.5 ft2

1 in. : 3 ft, 3ft by 9 ft, 18 ft2

Option B., 1 in.:3 ft, 4.5 ft by 9 ft, 40.5 ft²

Step-by-step explanation:

It is given in the question that 1 inches length on the blueprint corresponds to an actual length of 3 feet.

Therefore, the scale of the blueprint is 1 in. : 3 ft.

In the blueprint the dimensions of the bathroom

length = 3 inches and width = 1.5 inches ( scale = 1 in. = 3 ft )

The actual dimension of the bathroom's length = 3 inches = 3 × 3 = 9 feet

Actual bathroom's width = 1.5 inches = 3 × 1.5 = 4.5 feet

Actual area of the bathroom = Length × width

                                                = 9 × 4.5 = 40.5 feet²

Therefore, the answer would be Option B., 1 in.:3 ft, 4.5 ft by 9 ft, 40.5 ft²

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

d is the only accurate one
