All of the rings of a ladder are parallel and the top rung is perpendicular to a side of the ladder. What conclusion can be reac
Ronch [10]

Perpendicular sides or lines meet at right angles. The conclusion that can be reached is that:

<em>1. all of the rings are perpendicular to that side.</em>

The statements in the question can be listed as:

  1. <em>Rings in the ladder are parallel</em>
  2. <em>Top ring is perpendicular to the side of the ladder</em>

<em />

From statements 1 and 2 above, we understand that;

<em>All other rings in the ladder are parallel to the side ring</em>

This means that the relationship between the top ring and the side of the ladder is the same as the relationship between other rings and the side of the ladder

i.e. the side rings are also perpendicular to the side of the ladder

Hence, the conclusion that can be reached is:

<em>1. all of the rings are perpendicular to that side.</em>

A landscaping company is delivering crushed stone to a construction site .The Table shows the total weight in pounds W, of n loa
irina1246 [14]

Answer:

Option (C)

Step-by-step explanation:

From the given table,

Dependent variable is the weight of each load and independent variable is number of loads of crushed stones.

Let the equation that represents the total weight is,

W = mn + b

Where 'm' = slope of the line

b = y-intercept

n = number of loads

Since graph starts from the origin (0, 0), y - intercept 'b' will be 0.

Two points lying on the line are (0, 0) and (1, 2000)

Slope of the line 'm' = \frac{y_2-y_1}{x_2-x_1}

                                  = \frac{2000-0}{1-0}

                                  =2000

Therefore, equation will be,

W = 2000n

Option (C) will be the answer.
