Answer
Explanation:
Step1: Recall water - freezing point in Fahrenheit
Water freezes at 32°F.
Step2: Calculate multiplication
$2\times100\times3=(2\times100)\times3 = 200\times3=600$.
Step3: Know the property of a cube
A cube has 6 faces.
Step4: Analyze symmetry of shapes
Not all shapes have one line of symmetry. For example, a circle has infinitely many lines of symmetry. So the answer is False.
Step5: Define the prefix "kilo -"
The prefix kilo means 1000.
Step6: Write in exponential form
$13\times13\times13 = 13^{3}$.
Step7: Recall the relationship between radius and diameter
In a circle, two radii of the same circle equal one diameter. So the answer is True.
Step8: Simplify the expression
$(8 + 2)-(5 + 2)=10 - 7=3$.
Step9: Define the term
A letter used to represent an unknown number is called a variable.
Step10: Define the term
The distance around a polygon is called the perimeter.
Answer:
- 32
- 600
- 6
- False
- 1000
- $13^{3}$
- True
- 3
- variable
- perimeter
