For each sentence, drag a word that will make the statement true.

Answer:

Equilateral triangles are always acute triangles.

Scalene triangles are sometimes acute triangles.

Right triangles are never acute triangles.

Obtuse triangles are sometimes isosceles triangles.

Step-by-step explanation:

Equilateral triangles are always acute because each angle is 60⁰.

Scalene triangles have sides that are different lengths. They can be right, obtuse, or acute.

A right triangle is never acute because it has a 90⁰ angle. Acute means all angles are less than 90⁰.

An obtuse triangle can be either scalene or isosceles. It always has one angle greater than 90⁰ (obtuse).

A theater can seat 725 people. The number of rows is 4 less than the number of seats in each row. How many rows of seats are the
OverLord2011 [107]
725 is equal to (number of rows)*(number of seats per row)
r = s-4
725 = (s-4)s
s^2-4s-725 = 0
Factoring: (s-29)(s+25) = 0
Thus there are 29 seats per row, and 25 rows.

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.

The table represents a linear function.What is the slope of the function?
Viktor [21]

Answer:

the slope is 4/3

Step-by-step explanation:

use the formula:

m=\frac{y1-y2}{x1-x2}

where x1 and y1 can be any point and x2 and y2 can be any point.

I used the last relation as my x1,y1 and second last relation as my x2,y2 because it is easier to subtract them.

\frac{10-2}{7-1} which is 8/6 or 4/3
