If you would like to know how many papers will be missing the name, you can calculate this using the following steps:

30% of 200 homework papers = 30% * 200 = 30/100 * 200 = 60 homework papers

The correct result would be a) between 50 and 70 papers will be missing the name.

Answer:

1 cm = 100 mi

28.9/1=28.9

28.9 x 100 = 2890 miles distance

2890 / 65 miles per hour = 44.4615 hours to drive

44.461/24 hours in a day = 1.85 rounded up is 2 days

About two days

the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of
marin [14]
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg 
V = 17280 / 87 
V = 198.62 m^3
