Answer:

Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

Step-by-step explanation:

Given: A Right Circular Cone

To find: Shape of of cross section when cone is cut by a plan parallel

to edge of cone

Cone has an apex on top and circle in base so if it is cut parallel to its edge we get a shape which is curved or pointy on one end while on the other end it is open due to circle.

Option A: Circle is closed from everywhere,

Thus it is not correct.

Option B: Ellipse is also not open from any end.

Thus, it is not correct.

Option C: Parabola is curved from one end and open from other end.

Thus this is correct.

Option D: We get parabola if cone is cur parallel to axis.

Thus it is also not correct.

Therefore, Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

To answer question 12, you first need to know the definition of a prism and a pyramid.

A pyramid is a 3-D structure with one base, whose outer faces are made of triangles, and meet at a single point at the top.

A prism is any 3-D shape with a base of any number of sides, another base with the same amount of sides, and faces joining the two together on every side of the bases.

12.
Shape A is a pyramid, because it has one base, and all the faces join together in at one point.

Shape B is a prism, because it has two bases, and faces joining every side of the bases.

Shape C is a prism.

Shape D is a pyramid.

For #13, you have to know the definition of a cube to figure out the math of how many cubes there are.

A cube is a 3-D shape with six sides, all made up of squares of the same size.

The box has a volume of 120 cubic inches, and each cube is 1 inch. Since every side of a cube is equal, a 1-inch cube is one cubic inch.

This means that a box with a volume of 120 cubic inches will fit 120 of the 1 inch cubes.

1 layer of the cubes, in the diagram, is 8 cubes by 3 cubes, or 24 cubes total.

To find the number of layers needed to fill the box, you divide 120 by 24.

120 ÷ 24 = 5

The answer to #13 is 5 layers.

What is mean of 8,3,3,7 and 4

Marina86 [1]

The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:

8+3+3+7+4= 25

25:5= 5

So the answer is: the mean is 5.

Tina is saving to buy a notebook computer. She has two options. The first option is to put $500 away initially and save $30 ever

Jlenok [28]

First option:
y=money saved
x=number of months

y=30x+500

Second option:

y=50x+200

We have this system of equations:

y=30x+500
y=50x+200

We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15

so;
y=30x+500
y=30(15)+500
y=450+500
y=950

Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.
