Answer:
The answer to your question is: 4 7/12 hours
Step-by-step explanation:
Data
1 5/6 mowing the lawn
3/4 trimming the hedge
2 2/3 weeding the garden
Process
Convert mixed fractions to improper fractions
1 5/6 = (6 + 5 ) / 6 = 11 / 6
2 2/3 = (6 + 2) / 3 = 8 / 3
Sum the fractions
11/6 + 8/3 + 3/4 = ( 22 + 24 + 9) / 12
= 55 / 12
= 4 7/12 hours
Answer:
Manu should considered only the possible rational zeros between -6 and 1, because those are the lower and upper bonds. A lower bond means that possible rational zero is not less than -6, and the higher number possible is not more than 1. This way, Manu has a interval to try. This rational method with bonds is aimed to narrow all possible solutions.
So, if Manu find out through the synthetic division that possible roots are +1/4,+1/2,+1,+5/4,+2,+5/2,+4,+5,+10,+20, then he only should considered those inside the intervals marked by the lower and upper bonds, which are +1/4,+1/2,+1, because the rest is higher than 1.
<em>Therefore, Manu should try first +1/4,+1/2 and +1.</em>
Y= -1/2x+2 since the y-intercept is 2 and the slope is going down by 1/2, you can find the equation using the y=mx+b form
