Time = Distance / Speed = 240 km / 80 km/h = 3 hours.

Time = Distance / Speed = 240 km / 80 km/h = 3 hours.

Time = Distance / Speed = 240 km / 80 km/h = 3 hours.

Percentage error = (Uncertainty / Measured value) * 100 = (0.01 / 5.67) * 100 ≈ 0.176%.

Total length = 3 * 1.20 m = 3.60 m. The uncertainty for 3 tables = 3 * 0.02 m = 0.06 m.

The range of possible true values is from 25.0 - 0.5 to 25.0 + 0.5, which is 24.5 °C to 25.5 °C.

Minimum possible volume = Measured volume - Uncertainty = 250.0 mL - 1.0 mL = 249.0 mL.

A conjunction is a part of speech that connects words, phrases, or clauses.

An interjection is a part of speech that expresses strong emotion or surprise, such as 'wow!', 'ouch!', or 'hey!'.

A noun names a person, place, thing, or idea.

An adjective provides additional information about a noun.

A preposition shows the relationship between a noun (or pronoun) and other words in a sentence.

A preposition shows the relationship of a noun or pronoun to other words in a sentence.

Let the number be x. The equation is 5x - 3 = 12. Adding 3 to both sides gives 5x = 15. Dividing by 5 gives x = 3.

Speed = Distance / Time = 150 km / 2.5 h = 60 km/h.

Distance = speed × time. Thus, distance = 60 km/h × 3 h = 180 km.

Distance = speed × time = 60 km/h × 3 h = 180 km.

The measurement 150.0 cm has 4 significant figures because the trailing zero after the decimal point is significant.

The leading zeros are not significant. Therefore, 0.00456 has 3 significant figures.

Absolute error = |Measured value - True value| = |12.30 - 12.5| = 0.2 cm.

The perimeter of a rectangle is given by 2(length + width). Thus, perimeter = 2(8 + 3) = 22 units.

The perimeter of a rectangle is given by 2(length + width). Thus, perimeter = 2(8 + 5) = 2 * 13 = 26.

The area of a triangle is given by (1/2) × base × height. Therefore, the area is (1/2) × 8 cm × 5 cm = 20 cm².

Using the Pythagorean theorem, 7² + 24² = 49 + 576 = 625 = 25², thus it is a right triangle.

The leading zeros are not significant. Therefore, 0.050 kg has 2 significant figures.

The area of a triangle is given by (1/2) * base * height. Thus, 60 = (1/2) * 10 * height. Solving for height gives height = 12 units.

Circumference = 2πr. Setting 31.4 = 2 × 3.14 × r gives r = 5 units.

The circumference C = 2πr. Setting 31.4 = 2 * 3.14 * r gives r = 5.

Circumference = π * diameter = π * 10.0 cm ≈ 31.4 cm. Uncertainty in circumference = π * 0.1 cm ≈ 0.314 cm.

The perimeter of a square is given by 4 times the length of one side. Therefore, if the perimeter is 36 cm, the length of one side is 36 cm / 4 = 9 cm.
