Last friday tony worked 7 1/2 hours. express this time as a fraction of the day.

There are 60 minutes in one hour.  If I told you that Tony took 1/2 hour to finish his exercise, you'd know that 1/2 hour is 30 minutes.  You get that by multiplying 60 minutes by 1/2: (1/2)*(60 minutes) = 60/2 = 30 minutes.  

So if Tony took 7/10 of an hour to finish his exercise, that's 7/10 of 60 minutes:

(7/10)*(60 minutes) = 420/10 = 42 minutes

i think it would be 42cm

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
