Choose the value of each expression.
Choices are 6, -6, 16/3 or 5 1/3, and -16/3 or -5 1/3
(-8) x 2/3
(-8) x (-2/3)
-18/3
18/−3
(−18)/(−3)

Answers

Step-by-step explanation:

1.

[tex]( - 8) \times \frac{2}{3} [/tex]

Put -8 over 1, then multiply.

[tex] \frac{ - 8}{1} \times \frac{2}{3} = \frac{ - 16}{3} [/tex]

Simplify:

[tex] (- \frac{16}{3}) =( - \frac{3}{3}) +( - \frac{3}{3}) + (- \frac{3}{3}) +( - \frac{3}{3}) +( - \frac{1}{3}) = ( - 5 \frac{1}{3} )[/tex]

-5 1/3 is the correct choice.

2.

[tex]( - 8) \times ( - \frac{2}{3} )[/tex]

Put -8 over 1, then multiply.

[tex] \frac{ - 8}{ - 1} \times \frac{ - 2}{ - 3} = \frac{ - 16}{ - 3} = \frac{16}{3} [/tex]

Simplify:

[tex] \frac{16}{3} = \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{1}{3} = 5 \frac{1}{3} [/tex]

5 1/3 is the correct choice.

3.

[tex] - \frac{18}{3} [/tex]

Turn into a whole number.

[tex]( - \frac{18}{3}) = (- \frac{3}{3}) + (- \frac{3}{3}) + (- \frac{3}{3}) + (- \frac{3}{3}) + (- \frac{3}{3}) + ( - \frac{3}{3} ) = - 6[/tex]

-6 is the correct choice.

4.

[tex] - \frac{18}{3} [/tex]

#4 has the same solution as #3, -6. Each has one negative numerator or denominator, making the same fractions negative.

5.

[tex]( \frac{ - 18}{ - 3} ) = \frac{18}{3} [/tex]

Turn 18/3 into a whole number.

[tex] \frac{18}{3} = \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{3}{3} + \frac{3}{3} = 6[/tex]

6 is the correct choice.

Solution:

Solve each multiplication using the knowledge of multiplying fractions.

Part-A (-8) x 2/3

(-8) x 2/3=> -8 x 2/3=> -16/3

Part-B (-8) x (-2/3)

(-8) x (-2/3)=> (8) x (2/3)=> 16/3

Part-C (-18/3)

(-18/3)=> -(3² x 2)/3¹=> -(3 x 2)=> -(6) = -6

Part-D (18/-3)

(18/-3) = 18/-3 x -1/-1 = -18/3=> -(3² x 2)/3¹=> -(3 x 2)=> -(6) = -6

Part-E (-18)/(-3)

=> (-18)/(-3) x -1/-1=> 18/3=> 6

On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 2 inches and one with a side length of 3 inches.

Which statement is true about the two triangles?


The two triangles are the same shape but not the same size.

The two triangles are the same size but not the same shape.

It is impossible to construct equilateral triangles with these side lengths.

The two triangles are the same size and same shape.

Answers

Answer:

Answer:

(B)

Step-by-step explanation:

We have to construct two equilateral triangles that is one with the side length of 2 inches and the another triangle with side length of 3 inches.

Now, both the triangles are equilateral triangles, thus they have same shape.

Also, both triangles have different side lengths, one having 2 inches and another having 3 inches, thus they have different size.

Hence, the true statement about the two triangles is:

The two triangles are the same shape but not the same size.

Therefore, option B is correct.

Answers

your answer is 102 m2

The surface area of the cube is 102 m².

What is a cube?

It is a polygon having six faces.

The volume of a cube is side cube.

We have,

If each face of the cube has an area of 17 m², then the length of each side of the cube can be found by taking the square root of 17 m²:

s = √17 m = 4.12 m

To find the surface area of the cube, we need to find the area of all six faces and add them together.

The area of each face is s²,

So the total surface area of the cube is:

SA = 6s²

Substituting s = √17 m, we get:

SA = 6 (√17 m)²

SA = 6 (17 m)

SA = 102 m²

Therefore,

The surface area of the cube is 102 m².
