Answer:

22cm by 6cm

Step-by-step explanation:

Width = x

Length = 3x + 4

x + x + 3x + 3x + 4 + 4 = 8x + 8

Perimeter = (8x + 8) cm

56 - 8 = 48cm

48/8 = 6

6 = x

Width = 6cm

Length = 22cm

Which measurements are equal to 671 decimeters? Check all that apply.

iren [92.7K]

Answer:

Answer:

Option A , D and E are correct.

67100 millimeters, 6.71 decameters and 6,710 centimeters measurements are equal to 671 decimeters

Step-by-step explanation:

Use conversion:

1 millimeters = 0.01 decimeter

1 kilometer = 10000 decimeter

1 hectometers = 1000 decimeter.

1 decameter = 100 decimeters

1 centimeters = 0.1 decimeter

As per the statement:

We have to find which measurements are equal to 671 decimeters.

67100 millimeters

Using conversion:

1 millimeters = 0.01 decimeter

then;

67100 millimeters = 671 decimeter.

0.671 kilometers

Using conversion:

1 kilometer = 10000 decimeter

then;

0.671 kilometers = 6710 decimeter.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.

Step-by-step explanation:

67100 millimeters

Using conversion:

1 millimeters = 0.01 decimeter

then;

67100 millimeters = 671 decimeter.

0.671 kilometers

Using conversion:

1 kilometer = 10000 decimeter

then;

0.671 kilometers = 6710 decimeter.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.

Given the universal set U = {v, w, x, y, z), and subsets A = {v, w, z} and B = {x, y, z), indicate the roster

lukranit [14]

If U = {v, w, x, y, z} and A = {v, w, z}, then

A' = {x, y}

(A' is the complement of A - it's the set containing all elements of U that are not in A)

If B = {x, y, z}, then

B' = {v, w}

Their their union is

A' U B' = {v, w, x, y}
