Describe in detail how you would create a number line with the following points: 3, 2.25, the opposite of 4, and – (–1 1/2).

Nezavi [6.7K]

First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).

For 3, I would count 3 numbers to the right from zero.

For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.

For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.

For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.

The universally accepted film size for movies has a width of 35 millimeters. If you want to project a movie onto a square sheet

dlinn [17]

Answer:

<h2>The scale factor is 285.7143 ≅ 286.</h2>

Step-by-step explanation:

The square sheet has an area of 100 square meters.

Hence, the width of the sheet is $\sqrt{100} = 10$ meters.

The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .

$x = \frac{10000}{35} = 285.7143$ .
