A garden hose fills a 2-gallon bucket in 5 seconds. The number of gallons, g is proportional to the number of seconds, t that the water is running. Select all of the equations that represent the relationship between g and t.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
