Answer:

175 = 7·5·5

Step-by-step explanation:

A student asked to write a prime factorization of 175. He wrote 7·25

The prime factorization of 175 will be given by :

It means, he has written it wrong as 7·25. It should be 7·5·5.

Hence, this is the required solution.

Answer:

175 = 7·5·5

Step-by-step explanation:

A student asked to write a prime factorization of 175. He wrote 7·25

The prime factorization of 175 will be given by :

175=7\times 5\times 5

It means, he has written it wrong as 7·25. It should be 7·5·5.

Hence, this is the required solution.

Defining congruent triangles
seropon [69]

Answer:

E -->R

D-->K

O-->O

Step-by-step explanation:

Assuming you are asking for congruent parts, correspondence is the part which corresponds and is also equal.

Here Angle E corresponds and is congruent to Angle R in these congruent triangles.

Angle D is congruent and corresponds to Angle K for these congruent triangles.

Angle O is equal to Angle O as they are vertical angles across a vertex.

Find the Volume of this Octagonal Pyramid.<br> "B" represents the Area of the octagon base.
Dominik [7]

Answer:

7.06 x 10^(-7) ft 3

Step-by-step explanation:

We have the formula to calculate the volume of an octagonal Pyraamid as following:

<em>+) Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>

As given, the base of the pyramid is an octagon with area equal to 15mm2

=> Area of the base = 15 mm2

The height of the pyramid is the length of the line segment which is perpendicular to the base - which is the red line.

=> Height = 4mm

So we have:

<em>Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>

<em>= 1/3 * 15 * 4 = 20 mm3</em>

<em />

As: 1 mm3 = 3.53 x 10^(-8) ft 3

=> 20 mm3 = 7.06x10^(-7) ft 3

So the volume of the pyramid is :  7.06 x 10^(-7) ft 3

HELP MEH<br> I can't figure this out. Please explain
vova2212 [387]

Answer:

x ≈ 33.0

Step-by-step explanation:

The third angle in the triangle is

180° - 70° - 76° = 180° - 146° = 34°

Using the Sine rule in the triangle

\frac{x}{sin76} = \frac{19}{sin34} ( cross- multiply )

x × sin34° = 19 × sin76° ( divide both sides by sin34° )

x = \frac{19sin76}{sin34} ≈ 33.0 ( to the nearest tenth )
