The bases of a triangular prism are equilateral triangles, since they have similar sides: 5, 5, and 5

An equilateral triangular prism is a three-dimensional form having its bases as equilateral triangles. A triangular prism is a prism bordered on the top and bottom by two paralleled triangular bases and bounded on the flanks by three rectangular faces.

<h3>What is a formula for a triangular prism?</h3>

volume = 0.5 * b * h * length , where b is the length of the base of the triangle, h is the height of the triangle and length is prism height. area = length * (a + b + c) + (2 * base_area) , where a, b, c are sides of the triangle and base_area is the triangular floor area.

<h3>What is equilateral prism?</h3>

Equilateral prisms feature three equal 60° angles and are often referred to as spreading prisms. Equilateral prisms are perfect for wavelength separating applications.

Estimates of the number of casualties vary greatly and are difficult, if not impossible, to verify. Conservative estimates assume that from 1958 to 1961, over 14 million people died of starvation, and the number of reported births was about 23 million fewer than under normal conditions. Other authors have estimated the number of famine-related death of up to 30 million or higher

Which expressions can be used to find the coordinates of the midpoint of PQ with endpoints P(3, –1) and Q(–7, –6)? Select THREE

A line segment is a straight line with finite length, and thus, have to endpoints(points on either end). The correct options are 2, 3, and 5.

<h3>What are the coordinates of the midpoint of the line segment AB?</h3>

A line segment is a straight line with finite length, and thus, have to endpoints(points on either end).

Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

$x = \dfrac{p+m}{2}$

and

$y = \dfrac{q+n}{2}$

The midpoint of the points P(3, –1) and Q(–7, –6) is,

x = (-7+3)/2 = -4/2 = -2

y = (-6-1)/2 = -7/2 = -3.5

Now, if we look at the options, the third option will give as the value of the x-coordinate as,

[(1/2)(-7-3)] + 3

= [(1/2)(-10)] + 3

= -5 + 3

= -2

This is the actual coordinate of the midpoint, therefore, this option is correct.

Similarly, the option two expresses the y-coordinate of the midpoint,

(-1 - 6)/2 = -3.5

Also, option five correctly depicts the value of y-coordinate,

-(5/2)-1 = -2.5 - 1 = -3.5

Hence, the correct options are 2, 3, and 5.

Russia, the world's largest country (by total area), comprises much of northern Eurasia, and stretches over a vast expanse of Europe and Northern Asia.[1] Due to its size, Russia displays both monotony and diversity. As with its topography, its climates, vegetation, and soils span vast distances.[2] From north to south the East European Plain is clad sequentially in tundra, coniferous forest (taiga), mixed and broadleaf forests, grassland (steppe), and semi-desert (fringing the Caspian Sea) as the changes in vegetation reflect the changes in climate. Siberia supports a similar sequence but is predominantly taiga. The country contains forty UNESCO biosphere reserves

Select the correct answer. A number is selected at random from the set {2, 3, 4, ... 10}. Which event, by definition, covers the

Shkiper50 [21]

C. The number is even or less than 12

Explanation:

Number 2 can be selected randomly and According to option A the number selected should be greater than 2.

B option is saying that the number is not divisible by 5 but the sample set contains { 2,3,4,5,6,7,8,9,10} . 5 and 10 can be selected and they are divisible by 5.

According to C even number can be selected or the numbers that are lesser than 12. The word "or" should be note here . Any number even or odd may be selected but it will be lesser than 12 so this will be the correct option.

Every element of sample set is either prime or composite so the selected number can either be prime or composite

Square root of 9 is 3 and square root of 10 is greater than 3. Statement will not be correct if number 9 or number 10 got selected the

upper portion (6000ft - 6500 ft)

Explanation:

From the information given:

This activity involves exploring the Zion National Park geology. To achieve this, we need to download the Zion file & open it in Gougle Earth. This is followed by setting the vertical exaggeration to 0.5 & the measurement to feet/miles. The perspective view is also changed to a map view. Now, as viewed in Gougle Earth, the upper portion which is white in nature appears to be steeper than the lower portions. To the Toquerville, the area towards it is remarkably flat with slight undulations.
