O. Para fazer um bolo de caneca, são necessários 30 g de farinha de trigo. Juliana recebeu a encomenda de 60 desses bolos, quantos kg de massa do trigo ela irá precisar? a) \( 0,18 \mathrm{~kg} \). b) 180 g . c) \( 9,0 \mathrm{~kg} \). d) \( 1,8 \mathrm{~kg} \). e) 30 g .

Perform the indicated operation and simplify the result. \( \frac{4}{15}+\frac{2}{15} \) \( \frac{4}{15}+\frac{2}{15}=\square \) (Type a simplified fraction.)

B) \( 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2= \)

\( \frac{8}{5}-\frac{4}{5}=\square \) (Simplify your answer. Type a fraction.)

Combine. Be sure to simplify your answer whenever possible. \( \frac{11}{18}-\frac{1}{18} \) \( \frac{11}{18}-\frac{1}{18}=\square \) (Type a fraction. Simplify your answer.)

Find the \( 12^{\text {th }} \) term of the arithmetic sequence whose common difference is \( d=8 \) and whose first term is \( a_{1}=5 \).
