Answer:
D Price of a pencil
Step-by-step explanation:
In A the number of students has to be an integer because you can't have part of a student
In B most likely your teacher will give you your score in a whole number form like 95% and not 94.87% because they would round it if it isn't a whole number already
C is similar to A you can't have a part of a computer key
Lastly in D stores very frequently have there prices at something like $1.99 which isn't a integer
You can write equations for the length (l) and width (w) as
.. l -w = 3
.. 2(l +w) = 14
Divide the second equation by 2 and add the first equation.
.. (2(l +w))/2 +(l -w) = (14)/2 +3
.. 2l = 10
.. l = 5
Then
.. w = l -3 = 2
The length and width are 5 inches and 2 inches, respectively.
Answer:
3√2
Step-by-step explanation:
In this question, we are asked to get the value of √ ( x²-y² ), while the value of x² and y² are given to be 33 and 15 respectively.
Hence, x² =33 and y² = 15.
Putting the values of x² and y² in the above expression we get,
√ ( x²-y² ) = √ ( 33-15) = √18 =3√2. (Answer)
1. The natural numbers are those that are used for counting. Natural numbers cannot be negative.
2. A whole number is a member of the set {0,1, 2, 3, …} - this set is the set of natural numbers with zero. Whole numbers cannot be negative.
3. Integers include whole numbers and negative whole numbers. Integers can be positive, negative, or zero.
4. Real numbers include:
- natural numbers;
- whole numbers;
- integers;
- rational numbers;
- irrational numbers.
Real Numbers can also be positive, negative or zero.
Consider number -1.2. It is negative, then options 1 and 2 are wrong. Also option 3 is false, because 1.2 is not natural number (cannot be used for counting), then -1.2 is not integer. Number -1.2 is real number.
Answer: correct choice is D.
5/√6 = (5 * √6)/(√6 *√6) = 5√6/6 or 2.0412
<span>Nothing much to do after that really !!! </span>
<span>Edit : Well then the answer is 5√6/6 or just simply 5/√6 since it is already in the simplified form i really hope that helps:/</span>
