The basic unit of mass in the metric system is
-
Litre
-
Second
-
Gram
-
Pound
Correct Answer
A. GramExplanation
The basic unit of mass in the metric system is the gram. The gram is a unit of measurement for mass and is used to quantify the amount of matter in an object. It is a smaller unit compared to the pound, which is used in the imperial system. The litre is a unit of volume, and the second is a unit of time, so they are not the correct units for measuring mass. Therefore, the correct answer is gram.Rate this question:

If your body temperature is 37 degrees Celsius, your temperature is -
-
Low
-
High
-
Normal
-
Unpredictable
Correct Answer
A. NormalExplanation
A body temperature of 37 degrees is considered normal. The average normal body temperature for adults is around 37 degrees Celsius or 98.6 degrees Fahrenheit. This temperature indicates that the body is functioning within the normal range and is not experiencing a fever or hypothermia.Rate this question:

One litre is equal to _____________centilitres.
-
10
-
100
-
1/10
-
1/100
Correct Answer

What is the value of n in the proportion 5/8 = n/40?
-
10
-
20
-
25
-
40
Correct Answer
A. 25Explanation
In the given proportion 5/8 = n/40, we can cross multiply to find the value of n. Cross multiplying gives us 5 * 40 = 8 * n. Simplifying this equation gives us 200 = 8n. Dividing both sides by 8 gives us n = 25. Therefore, the value of n in the proportion is 25.Rate this question:

A certain coin weighs about 5 grams. How many coins would weigh 2 kg?
-
100
-
200
-
400
-
500
Correct Answer
A. 400Explanation
To find the number of coins that would weigh 2 kg, we need to convert the weight of the coins from grams to kilograms. Since 1 kg is equal to 1000 grams, we divide 2000 grams (2 kg) by 5 grams (weight of one coin). This gives us 400, which means that 400 coins would weigh 2 kg.Rate this question:

Which of the following is not a monomial?
-
-xyz
-
5
-
2x
-
1/3xyz
Correct Answer
A. 1/3xyzExplanation
A monomial is a mathematical expression that consists of only one term. In this case, all the options given are monomials except for 1/3xyz. This is because it is a fraction and contains multiple variables (x, y, and z), making it a polynomial rather than a monomial.Rate this question:

Thirty less than a number is written as
-
30 - n
-
N - 30
-
30>n
-
N<30
Correct Answer
A. N - 30Explanation
"Thirty less than a number" refers to subtracting 30 from a given number. If the number is represented by n, the correct expression is n - 30. Option A (30 - n) incorrectly reverses the subtraction, meaning 30 minus the number. Options C and D are inequalities, not expressions for subtraction, and thus do not represent "thirty less than a number."Rate this question:

What is the solution to the quadratic equation x^2 - 5x + 6 = 0?
-
X = 2 and x = 3
-
X = 1 and x = 6
-
X = -2 and x = -3
-
X = -1 and x = -6
Correct Answer
A. X = 2 and x = 3Explanation
To solve the quadratic equation x^2 - 5x + 6 = 0, we can factor it as (x - 2)(x - 3) = 0. Setting each factor equal to zero gives us the solutions x = 2 and x = 3.Rate this question:

Subtracting 5mn from -12mn is
-
-17mn
-
17mn
-
7mn
-
-7mn
Correct Answer
A. -17mnExplanation
To subtract -5mn from -12mn, we can think of it as adding 5mn to -12mn. Since the signs are different, we subtract the smaller absolute value from the larger absolute value and keep the sign of the larger value, which is negative. Therefore, -12mn + 5mn equals -17mn.Rate this question:

What is x in the expression x+5 = 16?
-
10
-
11
-
12
-
13
Correct Answer
A. 11Explanation
In the equation x + 5 = 16, the goal is to find the value of x. To isolate x, we need to subtract 5 from both sides of the equation. This will cancel out the +5 on the left side, leaving us with x = 16 - 5. Simplifying this further, we get x = 11. Therefore, the value of x in the expression is 11.Rate this question:

Express 2.34x103 in decimal notation.
-
2.343
-
234
-
2340
-
23400
Correct Answer
A. 2340Explanation
The correct answer is 2340. To express a number in decimal notation, we move the decimal point to the right or left based on the exponent. In this case, the exponent is 3, which means we need to move the decimal point 3 places to the right. Starting with 2.34, we move the decimal point to get 2340.Rate this question:

In 5 +3(2) - 6, which operation should be performed first?
-
Addition
-
Subtraction
-
Multiplication
-
Division
Correct Answer
A. MultiplicationExplanation
In the expression 5 + 3(2) - 6, the operation that should be performed first is multiplication. This is because according to the order of operations, multiplication and division should be done before addition and subtraction. In this case, the expression 3(2) represents the multiplication of 3 and 2, resulting in 6. Therefore, the multiplication should be performed first before proceeding with the addition and subtraction.Rate this question:
