<span>In general, if the pyramid has 'x' sides, then it will have 'x' lateral faces. Total Number of Faces = Number of Base Faces + Number of Lateral Faces. Total Number of Faces = 2 + x. So the formula is F=x%2B2 where "x" is the number of sides that the pyramid has and "F" is the total number of faces.</span>

Answer: The expression for number of faces of a pyramid =1+n

Step-by-step explanation:

A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .

Its base describe the number of other faces of it.

For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....

So the total number of faces in a pyramid = base + lateral faces

If a pyramid has n sides therefore it give rise to n lateral faces such that

The total number of faces in a pyramid= 1+n .

Shelby Middle School is thinking of changing its dress code. What would be the best way to collect data?

mixas84 [53]

Answer:

Choose every tenth student entering the school and ask them if they like the dress code or not.

Step-by-step explanation:

This is a question of sampling. We need to make non-biased predictions using non-biased data. We can sample from every tenth student to stay proportional. Sampling many students can collect more data and can help keep the data non-biased.

lozanna [386]

Answer:

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

Step-by-step explanation:

Given

Given that 74% of the animals at an animal shelter are dogs.

To determine:

About what fraction of the animals at the shelter are dogs?

Using the equation to find a fraction equivalent to 74%

$\:74\%=\:\frac{74}{100}$

Divide numerator and denominator by 2

$=\frac{\frac{74}{2}}{\frac{100}{2}}\:\:$

Cancel the common factor 2.

$=\frac{37}{50}$

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

$\displaystyle\int_{x=0}^{x=4}\int_{y=x}^{y=2x}\int_{z=0}^{z=y}2xyz\,\mathrm dz\,\mathrm dy\,\mathrm dx$

$2xy\displaystyle\int_0^yz\,\mathrm dz=2xy\left[\frac{z^2}2\right]\bigg|_{z=0}^{z=y}=xy^3$

$x\displaystyle\int_x^{2x}y^3\,\mathrm dy=\frac{15}4x^5$

$\displaystyle\frac{15}4\int_0^4x^5\,\mathrm dx=\dfrac{15}{24}4^6=2560$

Answer:

4 , 24 , 144 , 864 , 5184

This is a sequence which is multiplied by 6 with the new digit.

First: 4

second: 4 * 6 = 24

third: 24 * 6 = 144

fourth: 144 * 6 = 864

fifth: 864* 6 = 5184

sixth: 5184 * 6 = 31104

seventh: 31104 * 6 = 186624

This sequence is never ending. Write the first 5 five in sequence that's the answer.
