Tom and Becky can paint Jim's fence together in 12 hours. If all people paint at the same rate, how many hours would it take to
Delvig [45]

Answer: 8 hours

Step-by-step explanation:

Let x be the time taken by each person to paint the fence.

Given: Tom and Becky can paint Jim's fence together in 12 hours.

Since all people paint at the same rate, then we have the following equation ;-

\dfrac{1}{x}+\dfrac{1}{x}=\dfrac{1}{12}\\\\\Rightarrow\ \dfrac{2}{x}=\dfrac{1}{12}\\\\\Rightarrow\ x=24

Thus, the time taken by each person to paint the fence alone = 24 hours

Now, the time taken by all three paint together:-

\dfrac{1}{t}=\dfrac{1}{24}+\dfrac{1}{24}+\dfrac{1}{24}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3}{24}\\\\\Rightarrow\ t=\dfrac{24}{3}=8\text{ hours}

Hence, it would take 8 hours if all three paint together.

Suppose that 44 identical red wooden blocks and 99 identical white wooden blocks are to be​ stacked, one on top of​ another, to
kirza4 [7]

44 identical red wooden blocks can be arranged in 44! ways

99 identical white wooden blocks can be arranged in 99! Ways

If the 44 red blocks and the 99 white blocks are to be stacked on top of one another, the number of different color patterns that can​ result = 44! x 99!

 

44! = 2.65827157 x 10^54

99! = 9.33262154 x 10^155

44! x 99! = 2.48086426 x 10^210

 

Therefore, 2.48086426 x 10^210 different color patterns can ​result
