The sides of the base of a right square pyramid are 4 m in length , and its slant height is 8 m. If the lengths of the sides of

hram777 [196]

Answer:

Step-by-step explanation:

We have that the total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base, therefore it would be equal to:

As = 1/2 * p * h + l ^ 2

where l are the sides that measure 4, p is the perimeter that is the sum of the sides, and since there are 4 sides then it would be 16 (4 * 4), h the inclined height is 8, replacing we are left with:

As = 1/2 * 16 * 8 + 4 ^ 2

Ace = 80

Now, they say that the sides and the tilt height are multiplied by 4, the sides now measures 16, therefore the perimeter is 64 (4 * 16), the height would be 32, replacing would be:

As = 1/2 * 64 * 32 + 16 ^ 2

As = 1280

Therefore the factor would be:

1280/80 = 16

This means that to calculate the new surface area, it must be multiplied by the square of the number by which the sides and the inclined height are multiplied, that is, 4 ^ 2 = 16.

A recipe for four batches of bread uses 5 cups of flour how many cups of flour I need it for one batch I only have one cup of fl

spayn [35]

Answer:

Step-by-step explanation:

A recipe for four batches of bread uses 5 cups of flour.

Firstly, we want to determine the number of cups of flour needed to produce one batch of bread. This means we want to determine the unit rate of producing batches of bread. It becomes

If four batches of bread uses 5 cups of flour,

Then 1 batch of bread will use x cups of flour

4x = 5

x = 5/4 = 1.25

1 batch of bread will require 1.25 cups of flour

Secondly, we want do determine how many batches of bread that can be made using 1 cup of flour. It becomes

If four batches of bread uses 5 cups of flour, then

y batches of bread will need 1 cup of flour

5y = 4

y = 4/5 = 0.8

1 cup of flour will produce 0.8 batch of bread

What is the absolute value of Point B labelled on the number line? A number line with point A at coordinate negative 2.2, point

bulgar [2K]

Answer:

The absolute value of point B on the number line is 2.2.

Step-by-step explanation:

A number line is given with point A at coordinate negative 2.2, point B at coordinate negative 1.6, and point C at coordinate 1.2.

So, on the number line, all the points having negative value are on the left side of zero.

Position of the point A is -2.2,

Position of the point B is -1.6,

Position of the point C is -1.2.

The absolute value of any point on the number line is the distance of that point from zero.

So, the absolute value of point B on the number line is the distance of point B from zero which is |-2,2|=2.2.

Find the distance from the point to the given plane. (−8, 7, 6), x − 2y − 4z = 8

vlabodo [156]

The formula for the distance from a point (x, y, z) to the plane ax +by +cz +d = 0 is this:
.. distance = |ax +by +cz +d|/√(a^2 +b^2 +c^2)

For your point and plane, that is
.. distance = |-8 -2*7 -4*6 -8|/√(1^2 +2^2 +4^2)
.. = 54/√21
.. = (18/7)√21
