A cross section is the intersection of a (solid or point) and a(plane or line) .

Rina8888 [55]

Answer:

A cross section is the intersection of a solid and a plane.

Step-by-step explanation:

A cross section is the geometric place formed when an 3-D object (solid) is cut straight.

Imagine the shape that you can see when you cut a piece of cheese with a knife. If the piece of cheese is a cube, the resultant shape, the cross section, will be a square.

Also, you can imagine the shape formed when you cut a right cylinder (the solid) with a plane parallel to the base. In this case, the cross section will be a circle.

Depending on the form of the solid and the angle of the plane, different cross sections may be obtained.

The ratio 20/10=5/n. What does n equal?

DIA [1.3K]

N is equal to 2.5

I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5

Or we can do this solution.

20 5
---- = ---- ; do cross multiplication. 20n = 10(5)
10 n

20n = 50 ; to get n, divide both sides by 20. 20n / 20 = 50 / 20 = n = 2.50

Whichever way: 20/10 = 5/2.5

The Century club runs the concession stand during football games. They sell snacks and drinks. 50 snacks and 180 drinks will sel

katrin2010 [14]

Answer:

The cost of each drink is $1.5

Step-by-step explanation:

Let us represent

The cost of snacks = x

The cost of drinks = y

50 snacks and 180 drinks will sell for $320

Hence:

50x + 180y = 320....... Equation 1

75 snacks and 100 drinks will sell for $225.

Hence:

75x + 100y = 225....... Equation 2

Combining both Equations together

50x + 180y = 320....... Equation 1

75x + 100y = 225....... Equation 2

Multiply Equation 1 by 75 and Equation 2 by 50 to eliminate x

3750x + 13500y = 24000..... Equation 3

3750x + 5000y = 11250....... Equation 4

Subtract Equation 4 from Equation 3

8500y = 12750

y = 12750/8500

y = $1.5

Therefore, the cost of each drink is $1.5
