For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is needed for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to represent pi, and the formula for circumference = 2*pi*r)

Answers

A button with a circumference of 7.38 cm will need a buttonhole with the size of 2.35 cm.

Since the circumference is equivalent to 7.38 cm, the formula can be displayed as follows:
7.38 cm = 2πr
r = 7.38cm/2π
r= 1.1751592 cm
diameter = 2r
= 2.3503184 cm or approximately 2.35 cm

Vertical angles must: . . Check all that apply . . A. Be a linear pair. B. Have the same vertex. . C. Be adjacent . D. Be congruent.

Answers

The correct answers are:
B) have the same vertex
C) be congruent.

Explanation:
Vertical angles are defined as opposite angles that share only a vertex. This definition is why B is true.
Since they are opposite angles, that means that the sides of one angle will be opposite the sides of the other; since this is true, the angles must be congruent.

Answer: Vertical angles must have same vertex and be congruent.

Step-by-step explanation:

When two lines crosses each other , the opposite angles are known as vertically opposite angles or vertical angles where "vertical" refers to the vertex .

Also we know that Vertical angles theorem says that vertical angles are always congruent.

Therefore, Vertical angles must have same vertex and be congruent.

A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 800 centimeters tall.

Answers

You would turn this into a function f(x). So the constant rate (or slope) is 0.5, so you start off with f(x)=0.5x. But you know that it starts at 8000, which is your intercept. So your final result is
F(x)= 0.5x +8000
