Which system about this figure is true?

jok3333 [9.3K]

Answer:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

TRUE, it has rotational degree, FALSE, angle of rotation is 180 degrees

2)It has no reflection symmetry. FALSE

3)It has reflection symmetry with many planes of symmetry. TRUE

4) It has no rotational symmetry. FALSE

Step-by-step explanation:

Rotational Symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Symmetry Order = Number of turns it takes to get to its similar position.

Reflected Symmetry : When a line is drawn which divides the shape in to two equal halves it is called reflective symmetry.

Consider the given figure:

1) It has rotational symmetry with an angle of rotation of 90 degrees.

TRUE, it has rotational degree.

FALSE, it regains its identical shape in 90 degrees, it is in 180 degrees.

2)It has no reflection symmetry.

FALSE, the given figure has reflection symmetry along both horizontal and vertical axis.

3)It has reflection symmetry with many planes of symmetry.

TRUE, it has inflectional symmetry in Horizontal as well a in vertical plane.

4) It has no rotational symmetry.

FALSE, it has a rotational symmetry of ORDER 2

During the first seconds after takeoff, a rocket traveled 208 kilometers in 50 minutes at al

lukranit [14]

Answer:

The rocket has a faster unit rate and is $219\ km/h$ much faster than the penny

Step-by-step explanation:

Find the unit rate of each object and the compare the results

step 1

Find the unit rate per hour of the rocket

To find the unit rate divide the total distance by the time

Let

d -----> the distance in km

t -----> the time in hours

we have

$d=208\ km$

$t=50/60=5/6\ h$

Find the unit rate

$208/(5/6)=208*6/5=249.6\ km/h$

step 2

Find the unit rate per hour of the penny

To find the unit rate divide the total distance by the time

Let

d -----> the distance in km

t -----> the time in hours

we have

$d=153\ km$

$t=5\ h$

Find the unit rate

$153/5=30.6\ km/h$

step 3

Compare the unit rates

The units rate of rocket is $249.6\ km/h$

The unit rate of penny is $30.6\ km/h$

Find the difference

$249.6-30.6=219\ km/h$

therefore

The rocket has a faster unit rate and is $219\ km/h$ much faster than the penny
