Which phrase can be represented by an equation? twice as much as a number 12 less than a number half of a number is 15 the diffe

jeka57 [31]

Answer:

Half of a number is 15

Step-by-step explanation:

First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.

An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.

Twice as much as a number: 2X

12 less than a number: X - 12

Half of a number is 15: X/2 = 15

The difference of 20 and a number: 20 - X

As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the trian

mart [117]

Answer:

The area is 11317.51

Step-by-step explanation:

The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.

b+c<a

133+174 < 240

A triangle can be formed

To use Herons formula for the area

We find S = 1/2( a+b+c)

= 1/2(240+133+174)

= 1/2 (547)

= 273.5

Area = sqrt( S (S-a) (S-b)(S-c))

sqrt((273.5 ) (273.5 -240) (273.5-133) (273.5-174))

sqrt((273.5)(33.5) (140.5) (99.5))

sqrt(128085964.4)

11317.50699

The area is 11317.51

Six pyramids are shown inside of a cube. The height of the cube is h units. Six identical square pyramids can fill the same volu

The height of squared pyramid is $\frac{1}{3}h$ unit.

<h3>What is the volume of a cube?</h3>

A cube is a solid three-dimensional object with six square faces or sides, three of which meet at each vertex. One of the five Platonic solids, the cube is the only regular hexahedron. It contains 8 vertices, 6 faces, and 12 edges.

Volume of cube $= (side)^3 \ unit^3$

Given the height of cube is $h$ unit.

Volume of cube is $h^3 \ unit^3$

Let the height of squared pyramid is $x$ unit

Volume of squared pyramid is $\frac{1}{3} h^{2} \times x \ unit^3$

According to the question, we have

Volume of cube = $6 \times$ volume of squared pyramid

$\Rightarrow h^3=6 \times \frac{1}{3}h^2 \times x\\\Rightarrow h^3=2 \ h^2 \times x\\\Rightarrow h=2x\\\Rightarrow x= \frac{1}{2}h$

Therefore, the height of squared pyramid is $\frac{1}{3}h$ unit.
