Answer:

140

Step-by-step explanation:

If 8 out of 10 are carrying a briefcase, that means 2 out of 10 are not carrying one.

Use a proportion to find how many don't have a briefcase with 700 people

Let x represent the number of people without a briefcase:

\frac{2}{10} = \frac{x}{700}

Cross multiply and solve for x

10x = 1400

x = 140

So, 140 people do not have a briefcase

maks197457 [2]
940,000 is your answer
You have to divide 135 from 540,000 and then multiply 100. Which is 400,000.
540,000+400,000=940,000.

Which of the equations below represents
Ray Of Light [21]

The equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)

<h3>What is the equation of the ellipse represented in the graph?</h3>

Herein we have a representation of an ellipse in the image attached aside, ellipses are characterized by the following <em>standard</em> formula:

(x - h)² / a² + (y - k)² / b² = 1     (1)

Where:

  • (h, k) - Coordinates of the center
  • a, b - Lengths of the semiaxes

Please notice that ellipse will be vertical if b > a, otherwise it will be horizontal. The graph exhibits a <em>vertical</em> ellipse centered at the origin and therefore we conclude that (h, k) = (0, 0) and b > a (b = 10, a = 2). Finally, the equation that represents the graph of the ellipse is x² / 4 + y² / 100 = 1. (Correct choice: D)
