60² + 30² = 4500²

Opposite corner = 67.08 ft.

6² + 8² = 100²

The wire must be 10 ft.

7² + 14² = 245²

The rope is 15.65 ft.

180² + 300² = 122400²

He ran 349.85 ft.

I'm not too sure about question 3.

1. x >= 4, because 4 is dotted, and that means that 4 is included

2. x =/ 4, the third answer is correct, because all numbers except 4 are included

3. the first number line is the correct answer, because -3 is not included

4. the second number line is the correct answer, because -1 is included

5. the second number line is the correct answer, because 6 is not included

6. the first number line is the correct answer, because 0 is included

7. the second number line is the correct answer, because all numbers except -4 are included

8. the third number line is the correct answer, because -1,5 is included

When a number is included in an interval, it should have full dot on the number line, so that's how you know.

Hope this helps!

56. Suppose you wish to make a scale drawing of your living room,

Deffense [45]

Answer: $8.33\ in$

Step-by-step explanation:

You know that the longer side of your living room is 25 feet and the shorter side of your living room is 18 feet.

Then, knowing that in the scale drawing the shorter side is 6 inches, you can say that the scale factor is:

$scale\ factor=\frac{18}{6}\\\\scale\ factor=3$

<em>Let be "x" the longer side of the scale drawing in inches.</em>

In order to find it, you must divide the actual longer side of you living room by the scale factor calculated above. Then you get:

$x=\frac{25}{3}\\\\x=8.33\ in$
