To determine the density of grains, a student uses a 50ml beaker graded by 5ml increments and a scale with 1g absolute uncertain

labwork [276]

Answer:

The mass of the grains = 120 ± 1 g

Step-by-step explanation:

we are given the following:

Total mass of container + grains = 185 grams

Mass of container = 65 grams

Therefore, mass of grains is calculated as follows:

Mass of grains = ( Mass of container + grains) - mass of container

= 185 - 65 = 120 grams.

since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g

Madison went to the mall with her big sister last week and their mom drop them off at 1 o’clock and said I’ll pick you up at 2:3

DaniilM [7]

Answer:

36 minutes

Step-by-step explanation:

2/3 = 40 minutes

1/2 = 30 minutes

14/15 = 56 minutes

= 126 minutes

They were supposed to get picked up after an hour and a half, 1:00 - 2:30, which is 90 minutes. Subtract 90 from 126 because 126 is their total time out and 90 is the supposed time. Your answer is 36.
