Example Question #1 : Knowledge Of Number Sense, Concepts, And Operations

Give the next number in the sequence:

Possible Answers:

Correct answer:

Explanation:

The sequence of numbers is formed by starting with 5, and, for each consecutive term, adding a quantity that increases by 1 each time. The sequence is

,

the missing entry.

Example Question #1 : Mathematics

How many elements are in ?

Possible Answers:

Correct answer:

Explanation:

denotes the union of and , the set of all elements that are in , , or both. To find this set, first, collect the elements in both sets:

Arranging:

Removing duplicates:

There are 12 elements in this set.

Example Question #1 : Mathematics

How many elements are in ?

Possible Answers:

Correct answer:

Explanation:

denotes the intersection of and , the set of all elements the two sets have in common. These elements are underlined below:

is a set with three elements.

Example Question #1 : Knowledge Of Number Sense, Concepts, And Operations

Evaluate:

Possible Answers:

Correct answer:

Explanation:

In the order of operations, any operation within parentheses is always performed first. First, add 12 and 25:

Multiplication takes precedence over subtraction. Multiply 13 by 8 next:

Now subtract:

Example Question #1 : Knowledge Of Number Sense, Concepts, And Operations

Calculate

and round the result to the nearest hundredth.

Possible Answers:

Correct answer:

Explanation:

Add the decimals vertically by aligning the decimal points, and adding the digits without regard to the decimal point:

Round to the nearest hundredth (second place after the decimal point) by examining the next digit to the right. This digit is an 8, so round the hundredths digit up to 7. This makes the correct choice 0.67.

Example Question #1 : Knowledge Of Geometry And Measurement

One mile per minute equals approximately ______________ kilometers per hour.

Possible Answers:

102

64

8

97

Correct answer:

97

Explanation:

First convert 1 mile per minute into miles per hour by multiplying by 60, then simply convert 60 miles per hour to km per hour by 1.6 to get 96.6, rounded up to 97.

Example Question #2 : Knowledge Of Geometry And Measurement

Which of the following is a measure of volume?

Possible Answers:

Fluid ounces

Kilometer

None of these

Pounds

Correct answer:

Fluid ounces

Explanation:

Fluid ounces are the only provided measure of volume. Volume is measured in liquid displaced by an object. Kilometers are a measure of distance, and pounds are a measure of weight, which is related to, but not the same as, volume.

Example Question #3 : Knowledge Of Geometry And Measurement

Of what is a "Joule (J)" a unit of measurement?

Possible Answers:

Weight

Electricity

Speed

Energy

Correct answer:

Energy

Explanation:

Joules are units of measurement used to describe energy (kinetic or potential). While "electricity" may be a tempting option here, "energy" is more correct; while electrical energy can be measured in Joules, not all energy measured in Joules is electrical in nature.

Example Question #11 : Ftce

Which of the given statements about finding the perimeter of a triangle is accurate?

Possible Answers:

The perimeter of a standard triangle is not measurable

The perimeter of a standard triangle is equal to the sum of two of its sides

The perimeter of a standard triangle is equal to the sum of all of its sides

The perimeter of a standard triangle is equal to the product of all of its sides

Correct answer:

The perimeter of a standard triangle is equal to the sum of all of its sides

Explanation:

This is a basic, clear geometric rule that all students must know: for a standard triangle the sum of the sides is equal to the perimeter. No other answer was acceptable.

Example Question #12 : Ftce

The area of a triangle with height and base of length 12 is what?

Possible Answers:

Correct answer:

Explanation:

To solve for in the equation

,

subtract 3 from both sides to reverse the addition of 3:

The height of a triangle is , and the length of its base is . The area of a triangle with base and height is

,

so, substituting these values,

,

the correct response.
