First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
Answer:
2,785,996
Step-by-step explanation:
The function that has the same set of potential rational roots is
<span>4(3x5-2x4+9x3-x2+12). If you see it from your options I know this is the one who is closer to the same set you are looking for. </span>
Answer:
A)
3x + 24 + 10 = 5x - 10 - x + 2
34 = 2x -8 - x
34 = x - 8
42 = x
or
<u><em>x = 42 million</em></u>
B)
<u><em>CORRECT! (1.2 million)</em></u>
C)
<u><em>0.028 = 3% if rounded.</em></u>
<u><em>The death rate is 3% </em></u>
