Answer:

Let the short piece be x

The long piece is x + 6

The medium piece is 3x

Total

x + (x+6) + 3x = 11

5x + 6 = 11

5x = 11-6

x = 5/5

x = 1

Short piece is 1ft

Medium piece is 3ft

Long piece is 7ft

Answer:

Shorter piece : 1

Medium piece: 3

Longest piece: 7

Step-by-step explanation:

11 = a + b + c

a =longest

b = medium

c = shortest

a = 6ft + c

b = 3 × c

* put that all into the equation

11= (6+c) + (3×c) + c

11 = 6 + c + 3c + c

5 = 5c

c = 1

A pentagonal prism is cut by a plane perpendicular to the base. What is the shape of the cross section that is formed? A. a pent

iris [78.8K]

Answer: C. A rectangle.

Step-by-step explanation:

1. By definition, a cross section is the intersection of a plane and a body of three dimensions.

2. A pentagonal prism has a pentagon as its base and its lateral faces are rectangles.

3. If the pentagonal prism is cut by a plane perpendicular to the base, this means that the plane is parallel to lateral faces, then, the shape of the cross section that is formed is also a rectangle.

4. The answer is the option C.

consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen

katovenus [111]

When you write a function in the form $y=f(x)$ , y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

$16b = 4r - 12$

Add 12 to both sides

$16b+12 = 4r$

Divide both sides by 4:

$4b+3 = r$

So, we wrote the expression in the form $r = f(b) = 4b+3$ , which means that r is the dependent variable and b is the independent variable, as requested.
