7.33. Tom can paint Mr. Thatcher's fence in 6 hours, while Huck can paint Mr. Thatcher's fence in 5 hours. If they work together

Alik [6]

Answer:

It takes them 30/11 hours to paint them together.

Step-by-step explanation:

This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:

$Tom: R_{T}*6=1\\Huck: R_{H}*5=1$

We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:

$Tom: R_{T}=\frac{1}{6}\\Huck: R_{H}=\frac{1}{5}$

Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):

$(\frac{1}{6} +\frac{1}{5})*T=1\\\\T*(11/30)=1 , T = 30/11$

Therefore, the time it takes them to paint the fence together is 30/11 Hours

How do you find the vertical asymptote of a rational expression?

ElenaW [278]

Here is the answer to the question. Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. Therefore, in order to find the vertical asymptote of a rational expression, what you are going to do is to set the denominator equal to 0 and solve for x. Hope this helps.
