Write an expression for: Five more sodas than twice the number of chips? And Daniela has 12 more books than Nicole?

Which lengths can be used, directly or indirectly, to calculate the volume of the hexagonal right pyramid? check all that apply.

diamong [38]

Answer

A. XY and ST

B. VU and TW

D.TX and WX

Step-by-step explanation:

The question is on volume of a hexagonal right pyramid

The formula for volume of hexagonal right pyramid is

$V=\frac{\sqrt{3} }{2}a^2h$

where a is the base length and h is the height of the pyramid.

So to get the volume, you need to find the base area then multiply it by the height.

Let observe the lengths that can help you in calculating the volume.

Length XY is important because it is a base length

Length st is important because it is the height of the pyramid

Length VU/YZ is important because it is a base length

Length TW/TX is important because it could help you determine the slant height and if the apothem length is given, you can determine the height TS

Length XW is important because it is a base length

Length XS is not important because it is not the apothem length.Apothem length is a perpendicular bisector of the base length originating from the center of the pyramid

Therefore the correct pairs of lengths are ;

A. XY and ST

B. VU and TW

D.TX and WX

Answer:

x = 130 degrees

Step-by-step explanation:

Here, we want to find the value of x

mathematically, the sum of opposite interior angles equal the opposite exterior angles

In the triangle, we have only one interior angle

Now, as we can see, the angle that measures 150 is on a straight line with one of the angles in the triangle

Mathematically, the sum of angles on a straight line is 180

So we have it that the given angle in the triangle would be (180-150)

If we add this to the 100, we have the exterior angle which is x

Thus, we have it that;

x = 100 + (180-150)

x = 100 + 30

x = 130 degrees

Answer:

14.5 kg

Step-by-step explanation:

Arrange the numbers in increasing order, which will give

8kg, 8kg, 14kg, 15kg, 17kg, 19kg

You then find the middle number(s), which is [14kg & 15kg] in this case.

Then you add the middle numbers and divide by 2, hence

$\frac{14kg+15kg}{2} = \frac{29kg}{2} = 14.5 kg$
