Mark puts an object that has a mass of 58.2 kg in a cart that has a mass of 73.00 kg. How should Mark report the total mass to the correct number of significant figures? 131 kg, to have the same number of significant figures as 58.2 kg 131.2 kg, to have the same number of significant figures as 73.00 kg 131.20 kg, to have the same precision as 73.00 kg 131.2 kg, to have the same precision as 58.2 kg

The final answer of the sum of two numbers must contain the same number of significant figures as minimum number of significant figures among the numbers being added.

mass of object = 58.2 kg

mass of cart = 73.00 kg

Total mass = mass of object + mass of cart

Total mass = 58.2 + 73.00

Total mass = 131.2

between two numbers 58.2 has smaller number of significant figures. hence we round-off the answer to have the same number of significant figures as 58.2

so Total mass = 131 kg

D.) 131.2 kg, to have the same precision as 58.2 kg
