</span>


X^lg(x)=100^x:x  |Solve \ for \ x|


<span>|Use \ logarithms \ of \ both \ sides \ of \ the \ base \ 10|&#10;&#10;</span>

<span>
</span>

<span>lg (x ^ lg (x)) = lg (100x)&#10;&#10;</span>

<span>
</span>

<span>lg ^ 2 (x) = 2 + lgx</span>

<span>

lg 2 ^ x-lg x -2 = 0

What is the value of r, the part of the job that Marina can complete in 1 hour?
EastWind [94]

Answer:

0.4

Step-by-step explanation:

so, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)

if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer
