miskamm [114]
The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,

         n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)

Substituting the known values to the equation,

       n = (30 minutes)(1 chair / minute)(2 persons / chair)
                 n = 60 persons

Answer: 60 persons

One company estimates same-day delivery as more than three less than half the total number of miles. Which graph represents the
VMariaS [17]

By using an online graphing calculator, the overall equation represented by this scenario is plotted in the image attached below.

<h3>How to determine the graph?</h3>

Based on the information provided about this company with respect to its delivery and total number of miles to be covered, we would assign variables as follows:

  • Let y represent same-day delivery.
  • Let x be the total number of miles.

Next, we would translate the word problem into an algebraic equation by using an inequality:

y > x/2 - 3

Also, we would determine the intercepts as follows:

When x = 0, we have;

y = 0/2 - 3

y = -3.

y-intercept = (0, -3).

For the x-intercept, we have:

When y = 0, we have;

0 = x/2 - 3

x/2 = 3

x = 6.

x-intercept = (6, 0).

By using an online graphing calculator, the overall equation represented by this scenario is plotted in the image attached below.
