How many minutes are in 1 hour? — 60.1 hour = 60 minutes.
2 km = ___ m — 2,000.2 × 1,000 = 2,000 m.
Convert 300 cm to meters. — 3 m.300 cm ÷ 100 = 3 m.
How many seconds are in 1 minute? — 60.1 minute = 60 seconds.
How many inches are in 1 foot? — 12.1 foot = 12 inches.
To convert from a larger unit to a smaller unit, you should… — Multiply.Going from a larger unit (like km) to a smaller unit (like m) means you need MORE of the smaller unit, so multiply.
What is the formula for the perimeter of a rectangle? — P = 2 × (l + w).Perimeter = 2 × (length + width) because a rectangle has two pairs of equal sides.
What is the area of a rectangle with length 5 m and width 3 m? — 15 m².A = l × w = 5 × 3 = 15 m².
What is the perimeter of a square with side length 4 cm? — 16 cm.P = 4 × s = 4 × 4 = 16 cm.
What unit is used for area? — cm².Area is measured in square units (e.g., cm², m²) because it covers a 2D surface.
A room is 6 m long and 4 m wide. What is its perimeter? — 20 m.P = 2(6+4) = 2 × 10 = 20 m.
A square has side 9 cm. What is its area? — 81 cm².A = 9 × 9 = 81 cm².
Perimeter answers the question "how much ___?" — distance around.Perimeter measures the distance around the outside edge of a shape.
Area is measured in ___ units. — square.Area covers a flat surface, so it is measured in square units.
How many degrees are in a full rotation? — 360°.A full rotation is 360°.
What type of angle is exactly 90°? — Right.A right angle measures exactly 90°. It looks like a perfect corner.
An acute angle measures… — Between 0° and 90°.An acute angle is greater than 0° and less than 90°.
What tool is used to measure angles? — Protractor.A protractor is the tool used to measure angles in degrees.
A straight angle measures… — 180°.A straight angle measures exactly 180° — it looks like a straight line.
Which angle type is between 90° and 180°? — Obtuse.An obtuse angle is greater than 90° and less than 180°.
What is the vertex of an angle? — The shared endpoint of the two rays.The vertex is the point where the two rays of an angle meet.
An angle is 55°. Is it acute, right, or obtuse? — Acute.55° < 90°, so it is an acute angle.
A line plot shows Xs above a number line. Each X represents: — One data value (one measurement).Each X on a line plot represents ONE data point — one measurement or observation.
The value with the MOST Xs on a line plot is called: — The mode.The MODE is the value that appears most often — the one with the most Xs stacked above it.
A line plot has Xs at: ½ (×2), 1 (×4), 1½ (×1). What is the MODE? — 1.1 has 4 Xs — the most of any value. So the mode is 1.
What is the RANGE of data: ¼, ¼, ½, ¾, 1? — 1 − ¼ = ¾.Range = maximum − minimum = 1 − ¼ = 3/4.
How many total measurements are represented if a line plot has 3 Xs at ¼, 2 Xs at ½, and 1 X at ¾? — 6.Total data points = 3 + 2 + 1 = 6 measurements.
You measure plant heights: 2, 2, 3, 2, 4 inches. On a line plot, how many Xs are above the value 2? — 3.The value 2 appears 3 times in the data set, so there are 3 Xs above 2.
Which graph type shows individual measurements as Xs above a number line? — Line plot.A LINE PLOT uses Xs above a number line to show individual data values.
In a line plot of ribbon lengths (in cm): 3, 3.5, 3, 4, 3.5. What is the most common length? — 3 cm.3 appears twice; 3.5 appears twice; 4 appears once. They tie, but 3 also appears twice — this is a tie at 3 and 3.5. Both are modes, but 3 appears just as often as 3.5.
