The surface area of the Egyptian pyramid model is 340 square inches.

Option C is the correct answer.

A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

We have,

The base of the pyramid is a square with a side length of 10 inches.

And,

Area = 10 inches x 10 inches

= 100 square inches

The pyramid has four triangular faces, each with the same dimensions.

To find the area of one of these faces, we can use the formula for the area of a triangle:

Area = (1/2) x base x height

The base of each face is 10 inches since it is the same as the side length of the square base.

The height of each face is the height of the pyramid, which is 12 inches.

So the area of each triangular face.

= (1/2) x 10 inches x 12 inches

= 60 square inches

Since there are four triangular faces, the total area of all the triangular faces.

= 4 x 60 square inches

= 240 square inches

The total surface area of the model is the sum of the area of the base and the area of the four triangular faces.

= base area + triangular face area

= 100 square inches + 240 square inches

= 340 square inches

Thus,

The surface area of the Egyptian pyramid model is 340 square inches.

The slope of the line is really important, because first, it just wouldn't be a proper equation and second, "Slope shows both steepness and direction." If the slope isn't there, then we wouldn't know whether the equation is positive or negative.

So sorry if that's incorrect...

Answer:

K12 Answer

Step-by-step explanation:

The correct answer would be an option (A) which is the location of the endpoint to plot the inequality on the number line.​​

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.

Any directed number's location can be determined using a number line. There are positive and negative axes in it.

We have been given that inequality on the number line.

⇒ w – 0.7 > -1.1

⇒ w  > -1.1 + 0.7

⇒ w  > -0.4

⇒ w < 0.4

Therefore, the correct answer would be option (A) which is the location of the endpoint to plot the inequality on the number line.​​

#SPJ2

Answer: 30.43

Step-by-step explanation: The smaller triangle has an angle of 54°. The hypothenus is 20, so we're looking for the opposite using SOHCAHTOA

Sin x = opp/hyp

Sin 54 =opp/ 20

Opp= sin54 ×20

Opp= 16.18

Therefore, BD is 16.18

In the bigger triangle, with taking the angle 28° we have DC to be the adjacent.

Tan 28° = 16.18/adj

Adj = 16.18/tan 28°

Adj = 30.43

DC = 30.43
