1. write the fraction as a decimal. round to the nearest thousandth, if necessary. 6 . , _ . 7 0.086 0.857 8.571 1.167 2. find the quotient of 144 and -8. 12 -18 9 -36 3. multiply. -3(9 y) -27y 9y -3 -39 -3 y 6y 4. find the tenth term of the pattern. 0, 1, 4, 9, 16, 25, 49 64 100 81

1. (6/7) is a fraction that is slightly less than 1. The only sensible (and correct) choice is 0.857

2. Either your calculator or your knowledge of the factors of 144 should tell you
  144/-8 = -18

3. Assuming you intend -3·(9·y), you multiply the constants to get the simplified coefficient of y: -27y

4. The n-th term is (n-1)², so the 10th term is 9² = 81

Arhombus is a quadrilateral.
