Answer:

look at my Step-by-step explanation

Step-by-step explanation:

The perpendicular bisector of a line segment

open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.

Call the two points where these two arcs meet C and D. Draw the line between C and D.

CD is the perpendicular bisector of the line segment AB. Call the point where CD intersects AB E.

Suppose Z denotes the set of all integers, Z denotes the set of all positive integers, and Z− denotes the set of all negative in

ikadub [295]

Answer:

a) False

b) False

Step-by-step explanation:

We are given the following information:

Z is a set of all integers, $Z^+$ is a set of all positive integers and $Z^-$ is a set of all negative integers.

Q is a set of all rational numbers, $Q^+$ is a set of all positive rational numbers and $Q^-$ is a set of all negative rational numbers.

N is a set of all natural numbers.

a) False

We will show this with the help of a counter example.

$Z = 3\\Q = \frac{3}{4}\\\displaystyle\frac{Z}{Q} = \displaystyle\frac{3}{\frac{3}{4}} = \displaystyle\frac{8}{3}$

which is a rational number and not an integer.

b) False

We will show this with the help of a counter example.

$Z = 3\\Z^- = -5\\\displaystyle\frac{Z}{Z^-} = \displaystyle\frac{3}{-5} = -\displaystyle\frac{3}{5}$

which is a rational number and not a natural number.

Question 24 points)Bill cuts a circle out of a square piece of wood to use for a project.Approximately how much wood will be lef

maks197457 [2]

The square piece of wood measures 32 in per side,

Then the circle that can be cut off it has a radius of 16 in (half of the diameter 32 in)

Therefore, the area of the circle is going to be given by the formula:

$\begin{gathered} \text{Area}=\pi R^2 \\ \text{Area}=\pi(16)^2\text{ }\approx803.\, 84in^2 \end{gathered}$

And the area of the initial square was:

Area = 32^2 in^2 = 1024 in^2

Therefore the left-overs of the piece of wood would be the difference:

1024 in^2 - 803.84 in^2
