Step-by-step explanation:
There are always two types of relationships between two quantities. Either the relationship is Directly proportional or it would be Indirectly proportional. Directly proportional is a relation in which one quantity increases with the increase of the other quantity and vice versa. Whereas in indirectly proportional relationship, one quantity decreases with the increase of the other quantity and vice versa.
Now in this question, the given quantities are Distance traveled by a car and the amount of gas in the car. These two quantities have indirect proportional relationship. When the Distance traveled by the car increases, the amount of gas in the car decreases and vice versa.
Answer: (b) Provide hints on what the teacher thinks is important
Explanation: Clearly, the teacher selects what to ask in the tests, and it is plausible to think that (s)he will select problems that they deem important.
The teacher will know that students look at past tests, and so they will tend to change the wording and values in the tests to prevent plagiarism, so (a) is not the right choice.
Answer:
$3.75
Step-by-step explanation:
4 divided by 15= 3.75
Answer:
Statement 3
Step-by-step explanation:
<u>Statement 1:</u> For any positive integer n, the square root of n is irrational.
Suppose n = 25 (25 is positive integer), then
Since 5 is rational number, this statement is false.
<u>Statement 2:</u> If n is a positive integer, the square root of n is rational.
Suppose n = 8 (8 is positive integer), then
Since is irrational number, this statement is false.
<u>Statement 3:</u> If n is a positive integer, the square root of n is rational if and only if n is a perfect square.
If n is a positive integer and square root of n is rational, then n is a perfect square.
If n is a positive integer and n is a perfect square, then square root of n is a rational number.
This statement is true.
Divide both sides of the inequality by 5 to give an answer of a - 5 > 5. Group all the variables and constants to opposite sides of the inequality. For this given,
a > 5 + 5
which simplifies into a > 10. Thus, the answer is the fourth choice.
