If the radius is sqrt(3) m, write down two other irrational numbers the learners may encounter in similar measurements.

Natali, let's knock this out. 4. If the radius is sqrt(3) m, write down two other irrational numbers the learners may encounter in similar measurements. An irrational number is a number that cannot be expressed as a simple fraction and has a non-repeating, non-terminating decimal expansion. Two other irrational numbers could be: • sqrt(2) m • m 5. A shopkeeper buys sugar totalling 4 (1)/(2) kg. Express this in improper fraction. Step 1: Convert the mixed number to an improper fraction. 4 (1)/(2) = ((4 × 2) + 1)/(2) Step 2: Calculate the numerator. = (8 + 1)/(2) Step 3: Simplify the fraction. = (9)/(2) kg 6. A teacher asks learners to find the reciprocal of the number of hours they spend online each day. If a learner spends (3)/(4) hours online daily, find the reciprocal. Step 1: Identify the number of hours spent online. Hours = (3)/(4) Step 2: Find the reciprocal by inverting the fraction. Reciprocal = (1)/(3)4 Step 3: Simplify the expression. = (4)/(3) 7. A school science club uses a value of 2.5 × 10^3 J of energy. Write this energy in ordinary form. Step 1: Understand scientific notation. 10^3 means multiplying by 1000. 2.5 × 10^3 = 2.5 × 1000 Step 2: Perform the multiplication. = 2500 J 8. A digital thermometer records temperatures as integers. List any four consecutive integers between -3 and 3. The integers between -3 and 3 are -2, -1, 0, 1, 2. Four consecutive integers from this list are: -2, -1, 0, 1 Got more? Send 'em!
