Complete the brackets first and then multiply it all.
28x5x32= 4480
-25 is an integer and a rational number.
<h3>What is number system?</h3>
- A system of writing numbers is known as a number system.
- It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set.
- It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.
Now,
- Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.
- A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.
- Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.
- Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.
- A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.
Hence, -25 is an integer and a rational number.

Answer:
11.3
Step-by-step explanation:
i used the theorem of Pythagoras
You divided cm³ by litres, that's where you went wrong.
The volume of the cilinder is 753982 cm³ which is 753.982 litres
To fill it takes 753.982/0.2 seconds ≈ 3769.9 seconds.
In an hour there are 60*60=3600 seconds, so it takes slightly more than one hour.
But as you can see you were very close. It helps to always write the unit with any number.
The answer to that is 0. The distance in the y direction is 12 and there are 6 parts 5 before the point and 1 after. So 12/6 = 2 or the length of each part
add 5*2 to -10 = 10 - 10 = 0 that is your answer
