4) Trudy just measured her dog and found out that it weighs 181.7 kilograms, which is \( 77.4 \% \) more than the last time Trudy measured. How much did the dog weigh last time? 4) Round your answer to the nearest tenth. 4)

Factors of \( 56: 1,2,4,7,8,14,28,56 \) Factors of \( 42: 1,2,3,6,7,14,21,42 \) List the common factors: The greatest common factor (GCF)

Find the general term of the following arithmetic sequence then find the indicated term of the sequence. \( 4,13,22,31, \ldots ; a_{12} \) The general term of the given arithmetic sequence, \( a_{n}=\square \). (Simplify your answer.) The indicated term of the sequence, \( a_{12}=\square \). (Simplify your answer.)

1. Divide \( 18,102 \div 7 \)

Hari stays 1 km 350 m awi school. How many kilometr travel in a week if his schoc for 5 days a week and he take road everyday? \( \begin{array}{ll}\text { (A) } 13 \mathrm{~km} 500 \mathrm{~m} & \text { (B) } 131 \\ \text { (C) } 14 \mathrm{~km} 500 \mathrm{~m} & \text { (D) } 14\end{array} \)

Select all the perfect squares. - \( \sqrt{361} \) - \( \sqrt{224} \) - \( \sqrt{81} \) \( \sqrt{2} \) \( \sqrt{1} \)
