A typical shower drain can remove 480 gallons of water in 3 hours.

For the first-rate;

1,440 gallons in 3 hours

We calculate the unit rate.

By Dividing the total volume by the total time,

1440 / 3 = 480 gallons/ hours

For the second rate:

960 gallons in 120 minutes

Converting minutes to hours:

120 minutes = 2 hours

We calculate the unit rate.

By dividing the total volume by the total time,

960 / 2 = 480 gallons / hour

For the third rate:

720 gallons in 1.5 hours

We calculate the unit rate.

By dividing the total volume by the total time,

720 / 1.5 = 480 gallons / hour

Now,

480 gallons/ hour = 480 / 60 gallons/ minute = 80 gallons per minute

Reika [66]

Answer:

19/37

Step-by-step explanation:

The mathematics faculty at a college consists of 9 professors, 8 associate professors, 10 assistant professors, and 10 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor

Total number of people in the faculty =

9 professors + 8 associate professors+ 10 assistant professors+ 10 instructors

= 37 people

Hence,

The probability of choosing a professor or an instructor

= P( Professor) + P( Instructor)

= 9/37 + 10/37

= 19/37

Interquartile range = 3rd Quartile - 1st Quartile Class A: 89 - 66 = 23Class B: 94 - 79 = 15
IQR indicates the spread of the of the scores over the median. Class A has a spread that his more than 50% of the scores of Class B.

If the compound ratio of 7:5 and 8:x is 83:60 then find X

baherus [9]

Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.
