loris [4]

Answer:

Yes, the team members will reach the point, where they started.

Step-by-step explanation:

Let us convert our given distance in meters.

1 km = 1,000 meter.

2 km = 2*1,000 meters = 2,000 meter.

1 hectometer = 100 meters,

10, hectometers = 10*100 meters = 1000 meters.

1 Decameter = 10 meters.

300 decameters = 300*10 meters = 3,000 meters.

Let us Assume that team members traveled in a straight line.

We have been given that participants found 1st clue after 2 km and then went 10 hectometer further, so the participants are 2 km plus 10 hectometer away from starting point.

$\text{The distance between starting point and 2nd clue}=2000\text{ meter}+1000\text{ meter}$

$\text{The distance between starting point and 2nd clue}=3000\text{ meter}$

Since the second clue asked the participants to go back 300 decameters, so we will subtract 300 decameters from the total distance covered to reach 2nd clue.

$\text{The change in position}=3,000\text{ meters}-3,000\text{ meters}$

$\text{The change in position}=0$

Therefore, the team members will reach the point where they started after they follow the instructions for the second clue.

Which equation describes a line of symmetry for rectangle ABCD

Firdavs [7]

Answer:

C. $x = -2$

Step-by-step explanation:

A rectangle has two lines of symmetry. That is, the line that divides the rectangle into two equal halves.

Taking a look at the rectangle that is placed on the coordinate grid. At what points do you think the two lines of symmetry can be located at that will give us two possible equal halves?

One will be horizontal, the other will be vertical.

For the horizontal line, the line of symmetry can be located at y = 5. If an horizontal line cuts through the rectangle at y = 5, we would have two equal halves.

Thus, an equation for a horizontal line is often represented as $y = k$ . Where k is a constant, because every coordinate point on the horizontal line would have the same value of k, which is where the line cuts across the y-axis. The slope of am horizontal line remains zero also.

Therefore, the equation of the line of symmetry of the rectangle shown in the coordinate grid would be:

✅ $y = 5$

The second line of symmetry which is vertical, would cut across the rectangle at x = -2.

Thus, the slope of a vertical line is undefined.

The equation of a vertical line is represented as x = h.

Where h is a constant, since all coordinates along the vertical line would surely have a x-coordinate value of -2, regardless of what y-coordinate value they have.

Therefore, h, in this case is -2.

Thus, the equation that represents the second line of symmetry of the rectangle above would be:

✅ $x = -2$ .

The two equations that represent the two lines of symmetry of the rectangle, respectively, are:

$y = 5$

$x = -2$

From the options given, the only correct option provided is:

$x = -2$ .
