The scale on a set of blueprints of a house is 1 in. = 3 ft. On the
blueprint, one of the bedrooms measures 3.75 in. wide and 4.5
in. long. What is the perimeter of the actual bedroom?

40.5 feet

Step-by-step explanation:

It was given that the scale is 1 in. =3ft.

The perimeter of the blueprint measures 3.75 in. wide and 4.5 in. long.

The perimeter of the blueprint is

Perimeter =2(l+w)

We substitute the length and width to get:

Perimeter=2(3+3.75)

Perimeter=2(6.75)

Perimeter=13.5 in

To find the perimeter of the actual bedroom, we multiply by 3.

Perimeter of actual bedroom =3×13.5 ft=40.5ft

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

17   x 256=4352
