Use significant figures rule 6.021cm + 7.4cm + 0.68cm + 12.0cm = ?

10.4168m - 6.0m = ?

1.31cm x 2.3cm = ?

5.7621m x 6.201m = ?

20.2cm ÷ 7.4s = ?

40.002g ÷ 13.000005g = ?

8.41g + 2.067g = ?

5.11g - 0.042g = ?

(4.11 x 10^-6) (7.51 x 10^-4) = ?

8.45 x 10^7 / 6.74 x 10^3 = ?

9.7 x 10^8 / 8.6 x 10^-2​

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
