Is -1 ⅐ a natural, whole, integer, rational or irrational number?
lana66690 [7]

Answer:

Rational

Step-by-step explanation:

okay so a natural number is anything like 1,2,3,4...etc.

a whole number is like a natural number but includes 0's

an integer is numbers that can have both positive and negative numbers

but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)

this leaves...

Rational

now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared

Irrational

a number that has no end and cant be solved like 0.86866968.....  or 38 squared

17. A warehouse has 5 shelves long enough to hold 8 boxes and high enough to hold 4 boxes. All the shelves are full. How many bo
Sav [38]

Answer:

<h3>Total 20 boxes are there. </h3>

Step-by-step explanation:

Total number of shelves in a warehouse = 5 shelves.

Each shelve either can hold maximum 8  boxes with their lengths or can hold 4 boxes with their heights.

So, in that case only 4 boxes could be hold in each of 5 shelves because only 4 boxes could be fit with their heights.

Therefore, total number of boxes = 5 × 4 = 20 boxes .

<h3>Therefore, total 20 boxes are there. </h3>
