(05.01)A scale drawing of a living room is shown below. The scale is 1:40. 4 inches
6 inches
Show your work to determine the area of the room in square feet.

A=80 square feet.

Step-by-step explanation:

First, we find the area of the model. 6*4=24. Now, due to the ratio of 1:40, we know that every inch is actually forty inches. So, you do this:

24*40=960.

So, the area of the actual living room is 960 inches. Or 80 feet.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
