Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.

natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.

integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.

rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.

irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.


so your answer is integer and rational, hope this helped! :)

A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How mu
insens350 [35]
The sea turtle's speed is
v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min}

The girl's speed is
v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min}

The ratio of the turtle's speed to that of the girl is
\frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357

Answer: 5.36 faster  (nearest hundredth)

Answer: 3.19

Step-by-step explanation:

So to find the average I used a simple but pretty effective method

So the new average is 3.19

Jada opens a savings account with a deposit of $800. The bank will pay
leonid [27]

Simple Interest formula is :  I=P*r*t, where I = Amount of interest, P= Principal amount, r = rate of interest in decimal and t = time duration in year.

Given in the question that,  P = $800 and r = 4\frac{3}{4}% = 4.75% = 0.0475

<u>a.</u>  For t = \frac{1}{2} year ....

I= 800*0.0475*\frac{1}{2}\\ \\ I= 19

So, Jada will receive $19 interest at the end of 1/2 year.

<u>b.</u>   For t = 1 year ....

I= 800*0.0475*1\\ \\ I= 38

So, Jada will receive $38 interest at the end of 1 year.
