Answer:

6 \times  {10}^{3}  = 6000

Step-by-step explanation:

(1.5 \times  {10}^{ - 6} ) \times (4 \times  {10}^{9} )

= (1.5 \times 4) \times ( {10}^{ - 6}  \times  {10}^{9} )

= 6 \times ( {10}^{ - 6}  \times  {10}^{9})

= 6 \times  {10}^{ - 6 + 9}

= 6 \times  {10}^{3}

= 6000

John ran the 100-m dash with a time of 9.93 sec. If this pace could be maintained for an entire 26-mile marathon, what would his
slega [8]

You can infer from this problem that for every 100 m that John was able to run, it takes him 9.93 seconds. To get how much time is needed for 26 – mile marathon, you need to divide 26 miles by 100 meters. But first, you need to convert 26 miles to meters first.

1 mile = 1,609.34 meters

26 miles = 41,842.84 meters

41,824.84 meters / 100 meters = 418.43 x 9.93 seconds = 4,155 seconds or 69.25 minutes

The complete inequality is -2 < x < 35

<h3>How to determine the range of value of x?</h3>

The figure attached to the question is the given parameter

From the figure, we understand that:

Side length BA and side length BD are equal.

This is represented as:

BA = BD

Because the side length AC is less than the side length CD, then it means that:

The measure of the angle ABC is less than the measure of the angle CBD

This is represented as:

∠ABC < ∠CBD

Where

ABC = x + 2

and

CBD = 37

Substitute ABC = x + 2 and CBD = 37 in the inequality expression ∠ABC < ∠CBD

So, we have:

x + 2 < 37

Subtract 2 from both sides of the inequality

x + 2 - 2 < 37 - 2

Evaluate the differences

x < 35

From the question, we have the following incomplete inequality

-2 < x < [ ]

Complete the inequality as follows:

-2 < x < 35

Hence, the complete inequality is -2 < x < 35
