Answer:

Explicación paso a paso:

Primero, puede crear ecuaciones como este:

Carmen = x + 4x + 2

Daniel = 4x

Tomas = 9x + 2

Marco = 2

42 = 9x + 2 + x + 4x + 2 + 4x + x

38 = 19x

x = 2

La edad de Marco = 2, entonces:

Daniel = 4 (2) = 8

La edad de Daniel = 8

T = 9 (2) +2

Carmen = 5 (2) +2

La edad de Carmen = 12

entonces La edad de Tomás es = 20

Answer:

La edad de Tomas= 20.

Step-by-step explanation:

Primero, puede crear ecuaciónes como este:

C= x+4x+2

D=4x

T= 9x+2

M=2

42= 9x+2+x+4x+2+4x+x

38= 19x

x= 2

La edad de Marco= 2, entonces:

D= 4(2)= 8

La edad de Daniel=8

T= 9(2)+2

La edad de Tomas= 20

C= 5(2)+2

La edad de Carmen= 12

Angle XYZ is rotated 270 degrees counterclockwise about the origin to form angle X’Y’Z’. Which statement shows the measure of an
8090 [49]
It is fine that you did not include the measure of angle XYZ in your posting.

This question is testing your knowledge of the four types of transformations.
1) Translations - an item is "slid" to a new location.
2) Reflections - an item is "flipped" (usually over the x-axis or y-axis)
3) Rotations - an item is rotated, usually around the origin (the point (0,0) is the center of most rotations, especially in high school math).
4) Dilations - an item is enlarged or reduced by a certain ratio.

It the first three, the image after the transformation is congruent to the pre-image.  It has the same size and shape.  It is simply flipped, rotated, slid...

But... in the fourth, dilation, the image now has a different size.  It is still, however the same shape.

In geometry terms, after the first three transformations, the image is still "congruent" to the pre-image.  After dilation, the image is "similar" but not "congruent."

So... all that to say that when you rotate an angle around the origin, the measure of the angle doesn't change.

So the first choice is correct.  The measure of the image of the angle is the same as the measure of the angle.

The recipe says he needs 450 grams of rice for 6 people
Fynjy0 [20]

Answer:

1.35kg

Step-by-step explanation:

450g : 6 people

x : 18 people

To get from 6 to 18, multiply by 3 so do the same to the other side

450 × 3 = 1350g

To convert from g to kg divide by 1000

1350 ÷ 1000 = 1.35kg
