Answer:

the mass of the empty box is 4/3 kg.

Step-by-step explanation:

The total mass (box plus 4 books and 2 files) is 2 kg

When half of the load is removed (2 books and 2 files) the mass is 1 3/20.

We have the following equation:

2 kg - (x/2)= 1 3/20 kg

Where x is the total mass of the load (4 books and 2 files)

This steps where followed to solve the equation:

2 -x/2 = (20-3)/20

40-10x=17

23=10x

x=2/3 kg

That is the total mass of the load

Hence

2kg -2/3 kg= 4/3 kg, the mass of the box

ANSWER THIS AND GET A BRAINIEST . thank youu - 10 points
crimeas [40]

Answer:

18; 1h30m; 15

Step-by-step explanation:

<u>Part A:</u>

James traveled 45km, you can tell because that is where he stops.

It took him from 2pm to 4:30pm.

You can find this info on the x axis.

That means 45km took him 2.5 hours.

45/2.5=18

James travels 18km per hour.

<u>Part B:</u>

The stop is indicated by the flat part in the graph. This is because when he stops, the distance he is away from home is not changing.

His stop is from 4:30pm to 5pm.

This means that his stop is 1 hour and 30 minutes.

<u>Part C:</u>

James had to travel 45km to get back home. (45-0)

It took him from 5pm to 8pm.

This means that on his journey back, 45km took him 3 hours.

45/3=15

James travels 15km per hour.

Which fraction has a value that is equal to 3/4
Katena32 [7]
3/4
3.0/4=0.7R0.2 or 0.7 + 0.2/4
0.20/4=0.05R0.00 or 0.05 + 0.00/4
now put it all together
0.7R2 = 0.7 + 0.05R0.00 = 0.75 + 0.00 = 0.75

To convert any unit to it's "milli-" form always multiply the given value by 1000. The new value will be the value of in the "milli-" form.

The question asked to us is to convert 3.521 g to mg (or milligram). Thus, all that we need to do is to multiply 3.521 with 1000 and we will get the corresponding value in milligrams. Thus, in mg, 3.521 g is:

3.521\times 1000=3521 mg
