A lab technician is dividing a cell that has a diameter of \( 4.32 \times 10^{-4} \) millinijeters. Each of the new cells has a diameter measuring exactly one half of the diameter of the original cell. Which is the diameter of a new cell?

На автомашине планировали перевезти сначала \( 3 \frac{8}{9} \) т груза, а г том ещё \( 2 \frac{11}{18} \) т. Однако перевезли на \( 1 \frac{1}{4} \) т меньше, чем предпол гали. Сколько всего тонн груза перевезли на автомашине?

Work out \( \frac{2.56 \times 10^{6} \times 4.12 \times 10^{-3}}{1.6 \times 10^{-2}} \) Give your answer in standard form.

07. (CN 1995) A fração \( \frac{312}{455} \) é equivalente à fração irredutivel \( \frac{a}{b} \), logo \( a+b \) é igual a: a) 53. b) 55. c) 57. d) 59. e) 61.

\( \$ 272 \div 85 = \)
