How Many Lines Of Symmetry Does The Quadrilateral Below Have. A. 0B. 1C. 2 Which Of The Following Are

Answers

Answer 1

Answer:

C; A

Step-by-step explanation:

(coming from an 8th grader :)

1. should be A, because on each side of the quadrilateral there are two lines being mirrored.

2. should be C, because the angles are acute and not right or straight. you may be thinking “but there is a straight line” yes, you are right there’s a straight line, but there’s multiple angles consisted in making one whole angle.

squared.
Find the missing side.

Answers

Answer:

x = 10 units

Step-by-step explanation:

The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).

Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units

If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)

What is the volume of the right rectangular prism, in cubic centimeters? A prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters. cubic centimeters

Answers

The formula for volume is V = lwh

This means that the volume is equal to the length times the width times the height.

Multiply the three numbers for your answer.

Length = 4, width = 3, height = 9

lwh = 4cm X 3cm X 9cm = 12cm^2 X 9cm = 108cm^3

And there you have it! Your final answer is 108 cm^3 OR 108 cubic centimeters!

I do not mean to scare you, but this is the most basic volume formula! As you encounter different 3D shapes, the formulas will change!

What is a rectangular prism?

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same. Volume of a rectangular prism = Area of a base × Height.

Given that, a prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters.

We know that, the volume of a rectangular prism = Length×Breadth×Height

= 4×3×9

= 108 cubic centimeters

Therefore, the volume of the given rectangular prism is 108 cubic centimeters.

Solve the following inequality in two ways and make a claim as to which
method is more efficient.
1/4 (8n - 12) < n + 2

Answers

Answer:

The solution of the given inequality  n < 5

Step-by-step explanation:

Explanation:-

Given inequality

                     [tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]

Step(i):-

 Cross multiplication '4' we get

                    8 n - 12 < 4 ( n +2)

                    8 n - 12 < 4 n + 4×2

                    8 n - 12 < 4 n +8

      Subtracting  '4 n ' on both sides, we get

                 8 n - 4 n - 12 < 4 n - 4 n +8

                 4 n - 12  <  8

Step(ii):-

Adding ' 12 ' on both sides , we get

                4 n -12 + 12 < 8 + 12

                               4 n < 20

Dividing "4' on both sides , we get

                                 n < 5

The solution is n < 5

Conclusion:-

The solution of the given inequality  n < 5
