There are 180 degrees in a triangle so it is 80 degrees

Answer 2

Answer:

80 degrees

Step-by-step explanation:

There are six faces on the solid.

There are twelve edges on the solid.

There are eight vertices on the solid.

Step-by-step explanation:

The 3-D solid shape is a cube.

A cube is a regular hexahedron.

Hexahedron is a polyhedron with six faces (regular meaning all six are square).

So, there are six faces on a cube.

A cube has 12 edges because all faces are squares and congruent to each other, all 12 edges are the same length.

A vertex is a corner where edges meet. The plural is vertices.

a cube has eight vertices, a cone has one vertex and a sphere has none.

Can somebody explain how to find an area of a square?
Please note that the area's side lengths are all the same.
(The side lengths are all 1/3 or also known as 0.3333)

Answers

Answer:

0.66653334

Step-by-step explanation:

The area of the face of the square is the side length x the side length. So 0.3333 x 0.3333 = 0.11108889. Since a square has 6 sides, multiply 0.11108889 with 6. So it equals 0.66653334.

Finding are of a square is the same as any other shape, even if the sides are all the same length. You multiple length by width (1/3x1/3) which gives you about 0.1111

Step-by-step explanation:

Translate these into numerical values: 3 3/9 + 7 6/11 = 10 87/99

Find a common denominator or multiple that your denominator's (9 and 11) share. Their lowest common multiple is 99.

Take 3 3/9's and multiple the denominator by 11 to get your denominator of 99. What you do to your denominator also must be reflected in your numerator, so multiply it by the same factor of 11. You will get 3 33/99

Repeat for 7 6/11. Multiply your denominator (11) by 9 to get your denominator of 99. Do the same in the numerator (6) to get 54.

Now add your new values. 3 33/9 + 7 54/99
Your fractional values will add up to 87/99, and your whole number values will add up to 10. In this case, your fractional values do not exceed 1, so there is no need to work any further. Your final answer is 10 87/99

-(w+4)+2(4w-4)

help plz :’)

Answers

Answer:

The simplified answer is 7w - 12.

Step-by-step explanation:

-1(w+4) + 2(4w-4)

(-w -4) + (8w - 8)

7w - 12

Answer:

7w - 12

Step-by-step explanation:

-(w+4)+2(4w-4)

Step 1: Distribute

In this equation, there are two things being distributed, the -(w+4) and the 2(4w-4). Looking at -(w+4) makes you think that there is nothing to distribute but actually there is. Treat the - like a -1 so that it looks like -1(w+4) and then we distribute normally.

-1 x w = -w

-1 x 4 = -4

Put it together and you have:

-w-4

Then the 2(4w-4), with this, we need to distribute the 2 into the 4w and -4. To do this, you just multiply the numbers.

2 x 4w = 8w

2 x -4 = -8

Put those together and you have:

8w-8

After distributing, the equation should like:

-w-4+8w-8

Step 2: Combine Like-Terms

In the remaining equation, there are 4 things we can combine. The -w and 8w, and the -4 and -8. The reason that we are doing it in this order is because you cannot combine a number with a variable, like combining -4 with 8w. Now we just add (or subtract).

8w - w = 7w

-4 - 8 = -12

Leaving us with the fully simplified equation:

7w - 12
