How many cubes with side lengths of 1/2 cm does it take to fill up the prism

Mathematics

24 cubes can filled up the prism

Solution:

The image of the question is attached below.

Given data:

Length of the prism = 2 cm

Breadth of the prism = 1 cm

Height of the prism = $\frac{3}{2} cm

Volume of the prism = length × breadth × height

                                   $=2\times 1\times \frac{3}{2}

                                   =3 cubic cm

Volume of the prism = 3 cubic cm

Side length of the cube = $\frac{1}{2} cm

Volume of the cube = side × side × side

                                 $=\left(\frac{1}{2}\right)^{3}

                                 $=\frac{1}{8} cubic cm

Volume of the cube =  \frac{1}{8} cm

$\text{Number of cubes} =\frac{\text{Volume of the prism}}{\text{Volume of the cube}}

                          $=\frac{3}{\frac{1}{8} }

                          =3\times8

                          =24

Number of cubes = 24

Hence 24 cubes can filled up the prism.

-2x^2+4x-1 from 6x^2+3x-9
kirza4 [7]

Answer:

8{x}^{2}  - x   - 8

Step-by-step explanation:

We want to subtract

- 2 {x}^{2}  + 4x - 1

from

6 {x}^{2}  + 3x - 9

We set up the subtracttion problem to get:

6 {x}^{2}  + 3x - 9 - ( - 2 {x}^{2}  + 4x - 1)

We expand the parenthesis to get:

6 {x}^{2}  + 3x - 9  + 2 {x}^{2}   - 4x  + 1

Group similar terms:

6 {x}^{2}   + 2 {x}^{2} + 3x- 4x  + 1 - 9

We simplify to get:

8{x}^{2}  - x   - 8

Consider the expression 2√3 cos(x)csc(x)+4cos(x)-3csc(x)-2 √ 3 This expression can be represented as the product of the factors.
Alla [95]

Answer with explanation:

The given expression is:

 2 \sqrt{3}\cos x * \csc x+4 \cos x-3 \csc x-2\sqrt{3}\\\\=2 \cos x*(\sqrt{3}*\csc x+2)-\sqrt{3}*(\sqrt{3}*\csc x+2)\\\\\rightarrow (2\cos x -\sqrt{3})*(\sqrt{3}*\csc x+2)\\\\\rightarrow (2\cos x -\sqrt{3})*(\sqrt{3}*\csc x+2)=0\\\\(2\cos x -\sqrt{3})=0 \wedge (\sqrt{3}*\csc x+2)=0

  \cos x=\frac{\sqrt{3}}{2} \wedge \csc x=\frac{-2}{\sqrt{3}}\\\\x=\frac{\pi}{6},2\pi-\frac{\pi}{6}\\\\x=\frac{\pi}{6},\frac{11\pi}{6} \wedge x=\pi+\frac{\pi}{3} ,2\pi-\frac{\pi}{3}\\\\x=\frac{4\pi}{3},\frac{5\pi}{3}\\\\x={\frac{\pi}{6},\frac{11\pi}{6},\frac{4\pi}{3},\frac{5\pi}{3}}

What’s the circumference of this shape?xx
VikaD [51]

The hypotenuse of the triangle would be the diameter of the semi circle.

Using the Pythagorean theorem you can find that.

8^2 + 6^2 = x^2

64 +36 = x^2

100 = x^2

x = √100

x = 10

The diameter is 10, now find the circumference.

Circumference = diameter x PI = 10 x 3.14 = 31.4

Since it is a semi circle, the circumference would be 1/2 of that.

31.4 / 2 = 15.7

The perimeter would be 8 + 6 + 15.7 = 29.7
