Which scale would produce the smallest drawing? Explain your reasoning.

tatiyna

Answer:

1 millimeter: 1 meter

Step-by-step explanation:

Part a) scale 1: 100

That means----> 1 unit on the drawing represent 100 units in the actual

Example

100 units in the actual -----> represent 1 unit on the drawing

Part b) scale 1 millimeter: 1 meter

The scale is

1 millimeter: 1,000 millimeter or 1:1,000

That means----> 1 unit on the drawing represent 1,000 units in the actual

Example

100 units in the actual -----> represent 0.10 units on the drawing

Part c) scale 1 inch: 10 feet

The scale is

1 inch: 120 inches or 1:120

That means----> 1 unit on the drawing represent 120 units in the actual

Example

100 units in the actual -----> represent 0.83 units on the drawing

therefore

The scale 1 millimeter: 1 meter would produce the smallest drawing

A line passes through the point (-9,3) and has a slope of -2/3?

saveliy_v [14]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the slope m = -2/3 and the point (-9, 3). Substitute:

$y-3=-\dfrac{2}{3}(x-(-9))$

$y-3=-\dfrac{2}{3}(x+9)$ <em>use distributive property</em>

$y-3=-\dfrac{2}{3}x-\dfrac{2}{3}\cdot9$

$y-3=-\dfrac{2}{3}x-(2)(3)$

$y-3=-\dfrac{2}{3}x-6$ <em>add 3 to both sides</em>

$\boxed{y=-\dfrac{2}{3}x-3}$

Marcus is comparing the costs of two cellular phone services.

kolbaska11 [484]

The true statements about Marcus graph are:

The initial cost of phone service 1 is greater than the initial cost of phone service 2
The unit rate of phone service 2 is greater than the unit rate of phone service 2

<h3>How to determine the true statement</h3>

From the complete question, we have the following parameters:

<u>Phone service 1</u>

Initial cost: $40
Rate: $8.50 per service

<u>Phone service 2</u>

Initial cost: $30
Rate: $10.50 per service

By comparing the above parameters:

The initial cost of phone service 1 is greater than the initial cost of phone service 2
The unit rate of phone service 2 is greater than the unit rate of phone service 2

The above statements represent the true statements about the Marcus' graph
