Mathematics
1 answer:
babunello [35]3 years ago

Answer:

4\ frac {1}{9}

Step-by-step explanation:

The recurring part is .111111

Now the number is 4.1111111111111 and let this number be x.

If you get 10x we shall have

10x=41.1111111111..... Equation 1

x=4.11111.... Equation 2

Subtract equation 2 from 1

10x-x=41.11111111-4.11111111=37

9x=37 hence x=37/9

The number will be \frac {37}{9}=4\frac {1}{9}

Petra fills a small cardboard box with sand. The dimensions of the box are 3 inches by 4 inches by 2 inches. What is the volume
mr Goodwill [35]

Answer: 24 in³

Step-by-step explanation:

You know that the dimensions of the box are:

3 inches.

4 inches.

2 inches.

As each face of the cardboard box is a rectangle, you can conclude that it has the form of a rectangular prism.

Therefore, to calculate the volume of the box, you must multiply the dimensions given in the problem.

Therefore, you obtain that the volume of the box is:

V=(3\ in)(4\ in)(2\ in)\\V=24\ in^3

who ever gets all of these right will get 2 brainiest and a good rating and have a choice to be my friend.
prisoha [69]

Answer:

shown below

Step-by-step explanation:

1. The pair of angles shown in your diagram are vertical angles. Vertical angles are each of the pairs of opposite angles made by two intersecting lines. The pairs of vertical angles have the exact same measurement. Therefore, 5x and 100 must have the same degree measurement, or 100 degrees. Thus, 5x must equal 100, so 5x = 100, and x would be 20 degrees.

2. The diagram shows a right angle (90 degrees) formed by 3x degrees and 39 degrees. 3x and 39 are complementary, which means they add up to 90, not 180 (that's supplementary). Thus, 3x + 39 = 90, 3x = 51, and x = 17 degrees.

3.  The diagram shows a 180-degree angle formed by 6x degrees and 2x + 8 degrees. This means that 6x + (2x+8) equals 180. 6x + 2x + 8 = 180 and 8x + 8 = 180, 8x = 172, and x = 21.5 degrees.

4. A angle's supplement is basically 180 - (angle measure),  because you are finding the angle that when formed with the original angle creates a 180 degree angle. Thus, the supplement angle would be 180 - 47 which is 133 degrees.

5. The angles 115 and (5x-10) create a 180 degree angle, which means that 115 + (5x-10) = 180. Thus, x = 15.
