Given a = 3.3, b = 7.3, and c = 3.4, evaluate the expression ab − c 2.Ĩ5. Given a = 4.1, b = −1.8, and c = −9.5, evaluate the expression a − bc 2.Ĩ3. Given a = −6.24, b = 0.4, and c = 7.2, evaluate the expression a − bc 2.Ĩ2. In Exercises 69-80, simplify the given expression.Ĩ1. In Exercises 57-68, multiply the decimal by the given power of 10. In Exercises 29-56, multiply the decimals. In Exercises 1-28, multiply the decimals. Thus, correct to the nearest tenth of a square meter, the area of the circle is approximately To round to the nearest tenth of a square meter, identify the rounding digit and the test digit.īecause the test digit is greater than or equal to 5, add 1 to the rounding digit and truncate. Hence, the approximate area of the circle is A = 122.65625 square meters.
