Are natural numbers always/sometimes/never rational numbers

Answers

Answer 1
Answer: Natural numbers are sometimes rational numbers
Answer 2
Answer:

Final answer:

Natural numbers are always rational numbers since they can be expressed as fractions with a denominator of 1.

Explanation:

Natural numbers are always rational numbers. A rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. Since natural numbers are a subset of integers (positive whole numbers), they can be expressed as fractions with a denominator of 1. For example, the natural number 5 can be written as the fraction 5/1, which is a rational number.

The appetizer can be any one of 6 choices.  For each of those ...
The rice can be any one of 4 choices.

Total number of possible combinations is (12 x 6 x 4) = 288 .
there is 27 meals cause if you have 12 entrees and 6 appetizers you still have 12 so 2*6=12 so 2*12=24 and how many times can 4 go into 12 and that is 3 so 24+3=27

                    the answer is 27

Which strategy should be used to correctly solve this problem? Bill wanted to make a rectangular pool that had an area of 80 square feet. He wanted to put tile around it, but he wanted to use as little tile as possible. What are the dimensions Bill should use for his pool?

A.
Arrange 80 square tiles in different patterns until you get a rectangular shape. Count the number of tiles on the perimeter of this shape.

B.
Make a table showing all possible products of length and width that would equal an area of 80 square feet. Then start calculating the perimeter of each rectangle. Look for a pattern to decrease the number of calculations you have to make.

C.
Write a number sentence that could be used to calculate the area of a rectangle. Use guess and check to find two numbers that when multiplied will give a product of 80.

Answers

B, make a table of possible values

the best way to do it is actually not listed
to have max area with minimu perimiter, try to get the sides as close measure to each other as possible


I would pick B though

What's different with census and sample?

Answers

A census is a study of every unit, everyone or everything, in a population. It is known as a complete enumeration, which means a complete count. A sample is a subset of units in a population, selected to represent all units in a population of interest.
I know when you do a census, you cover the entire population but when you take a sample, you select a group from the population. There can be only one census but there can be many different samples from the same population. Hence, the latter results in sampling error (because it is just one aspect of the population)

Graph the image of QRS after a rotation 270º counterclockwise around the origin.

Answers

Answer:

Q=(1,-5)

R=(5,-5)

S=(2,-7)

Step-by-step explanation:

5x=2x-15
y=2x-15
and y=5x

Answers

5x = 2x-15
3x = -15
x = -5

substitute x = -5 into one of your equations
so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25
5x=2x-15 =  x=-5
