Answer 1

Answer:

50.5 m^3

Step-by-step explanation:

Volume of pyramid = 1/3 × base area × height.

Height: 11Base Dimensions: 4.3 and 3.2

Area of Base:

[tex]4.3 * 3.2[/tex] [tex]13.76[/tex]

Next, we multiply 13.76 by 11.

13.76 × 11151.36

Lastly, divide by 3 and round to nearest tenth.

151.36 ÷ 3 50.453333..≈ 50.5

Therefore, the answer is 50.5 m^3

Using the perimeter formula of the Isosceles triangle the equation 2x + 2.1 = 7.5 is derived. The correct option is D.

What is the isosceles triangle?

Triangle is a polygon that has three sides. The sum of the angle of the triangle is 180 degrees. The two sides of the triangle are equal.

Given

The isosceles triangle has a perimeter of 7.5 m.

We know the perimeter of the Isosceles triangle.

Perimeter = Sum of all sides of the triangle

Let the sides be x and y and

And let y be the shortest side.

For y = 2.1 m, the equation will be

[tex]\rm Perimeter = x + x +y\\[/tex]

On simplifying the equation, we get

2x + 2.1 = 7.5

The required equation is 2x + 2.1 = 7.5.

Thus, option D is correct.

Question
Is it possible to construct a triangle with side lengths of 3, 6, and 9 units? If not, explain why not

Answers

Answer:

Step-by-step explanation:

No.

The triangle inequality theorem says that ANY two sides of a triangle MUST be greater than the third side.

In this case 3+6 is equivalent to 9 (it wouldn't be a triangle; just be a straight line), NOT greater, therefore is is not possible to construct a triangle with the given side lengths.
