Multiplication and division of measurements Decide whether each proposed multiplication or division of measurements is possible. If it is possible, write the result in the last column of the table. proposed multiplication or division (3.0 g)-(0.033 kg) = ? (9.0 m²')- (8.0 m) = ? (3.0 kg)-(1.0 m²) = ? Is this possible? yes Ono yes no yes no result 0 0 0.9 ロ・ロ X μ Olo 0² $

How many seconds are there in 3.7 years? (Use 365 days/year) (You do not need to put in your units & make sure to use the proper number of significant figures.

Perform the following calculations: a) 14.86 ml + 15.0 ml + 14.980 ml = b) (42.927 g/ml)(9.00 ml) = Round off the answers to the proper significant figures.

= MEASUREMENT AND MATTER Setting up a unit conversion A student sets up the following equation to convert a measurement. (The ? stands for a number the student is going to calculate.) Fill in the missing part of this equation. Note: your answer should be in the form of one or more fractions multiplied together. g (75. 1/2) - = ² - ? mL x10 X L 9 CUB

Bernard weighs a jar of pennies to find out how much they are worth. After subtracting the weight of the empty jar, he finds that the pennies have a total mass of 6.42 +/- 0.1 kg. Assuming that each penny weights 2.5 g, and taking into account the uncertainty of the measurement, what is the minimum value of the pennies (expressed in dollars)?
