Question

Accepted Answer

### 1.
# Brief Explanations:
The term for the percent added to a price is "Markup", as markup refers to the amount added to the cost price to determine the selling price, often expressed as a percentage.
# Answer:
Markup

### 2.
# Brief Explanations:
Salesmen receive "Commission" when they sell an item, which is a percentage or fixed amount of the sale price as their earnings.
# Answer:
Commission

### 3.
# Brief Explanations:
A fraction or its opposite (negative) is related to "Rational number" (though the list had "rational number" as a term, and a fraction is a rational number, and its opposite is also rational. The term here is likely "Rational number" in the context of the list, but also, in terms of operations, the opposite of a fraction (e.g., $\frac{a}{b}$ and $-\frac{a}{b}$) are related. But from the list, "Rational number" is a term, and a fraction is a rational number, and its opposite is also a rational number. So the answer is "Rational number".
# Answer:
Rational number

### 4.
# Brief Explanations:
Numbers that are the same distance from zero on the number line are "Opposites", for example, 5 and -5 are opposites as they are both 5 units from zero.
# Answer:
Opposites

### 5.
# Brief Explanations:
The distance from zero on the number line is called the "Absolute Value", so for a number $x$, its absolute value $|x|$ represents its distance from zero.
# Answer:
Absolute Value

### 6.
# Brief Explanations:
The basic equation to find distance ($d$) when rate ($r$) and time ($t$) are known is $d = r	imes t$ (distance equals rate multiplied by time).
# Answer:
$d = rt$ (or $d = r 	imes t$)

### 7.
# Brief Explanations:
To find rate ($r$) when distance ($d$) and time ($t$) are known, we rearrange the distance formula $d = rt$ to get $r=\frac{d}{t}$ (rate equals distance divided by time).
# Answer:
$r=\frac{d}{t}$

### 8.
# Brief Explanations:
To find time ($t$) when distance ($d$) and rate ($r$) are known, we rearrange the distance formula $d = rt$ to get $t=\frac{d}{r}$ (time equals distance divided by rate).
# Answer:
$t=\frac{d}{r}$

### 9.
# Brief Explanations:
Subtracting a negative number is the same as adding its positive (the opposite). For example, $a - (-b)=a + b$, so subtracting a negative is adding a positive.
# Answer:
positive

### 10.
# Brief Explanations:
Subtracting a positive number is the same as adding its negative (the opposite). For example, $a - b=a+(-b)$, so subtracting a positive is adding a negative.
# Answer:
negative

### 11.
# Brief Explanations:
When multiplying two positive numbers, the result is positive. So positive $	imes$ positive = positive.
# Answer:
positive

### 12.
# Brief Explanations:
When multiplying two negative numbers, the result is positive (negative $	imes$ negative = positive, by the rules of sign multiplication).
# Answer:
positive

### 13.
# Brief Explanations:
When multiplying a negative number and a positive number, the result is negative (negative $	imes$ positive = negative, by the rules of sign multiplication).
# Answer:
negative

### 14.
# Brief Explanations:
When multiplying a positive number and a negative number, the result is negative (positive $	imes$ negative = negative, same as negative $	imes$ positive due to commutativity of multiplication).
# Answer:
negative

### 15.
# Brief Explanations:
Speed is a scalar quantity (magnitude), and when we add direction to it, we get a vector quantity called "Velocity". So speed + direction = velocity.
# Answer:
Velocity
