Answer:

A² + B² = C²

5² + x² = 9²

25 + x² = 81

x² = 81 – 25

x² = 56

x = √56

x = 7.483

x = 7.48

x = 7.5

I hope I helped you^_^

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

Look at the figure. Classify the pair of angles: <4 and <5.

VMariaS [17]

Answer:

Option B

same-side interior angles

Step-by-step explanation:

Given in the question, two non parallel lines a and b.

The area between lines a and b is called the interior of the two lines.

Angles 4 and 5 are same-side interior angles.

Other options are wrong because:

The area which not between lines a and b is called the exterior

Corresponding angles are on same side of the traversal line.

Example

Angles 1 and 5

Alternate interior angles are in interior region but in opposite side of traversal line.

Example

Angles 3 and 5
