Let's look at work rates per minute.
Together they can paint the wall in x minutes.
Working together, in 1 minute, they do 1/x of the job.
The student who paints the wall in 16 minutes does 1/16 of the job in 1 minute.
The student who paints the wall in 24 minutes does 1/24 of the job in 1 minute.
Together, they do 1/16 + 1/24 of the job in 1 minute, but from above, we see that together, they do 1/x of the job in 1 minute, so 1/16 + 1/24 must equal 1/x. That gives us our equation.
1/16 + 1/24 = 1/x
1/16 * 3/3 + 1/24 * 2/2 = 1/x
3/48 + 2/48 = 1/x
5/48 = 1/x
x = 48/5 = 9.6
Answer: It takes them 9.6 minutes, or about 10 minutes to do the job together.
Answer:
15/8
Step-by-step explanation:
Assuming you mean tan theta
Tan(theta) = opposite/adjacent
We know the adjacent side is 8 so the bottom of the fraction must also be 8
C: 15/8 is the only option that fits this criteria
X= 1.80/10 . x is the number of dimes. 1.80 is your total and 10 represents the worth of the dime
The larger the number of simulations the more likely are the results to be closest to those predicted by the probability theory.
When large number of simulations are run, some results might be higher than the results of probability theory, some results might be lower than the results of the probability theory and some might be exactly the same. So the average of all these results will be close to the results of Probability Theory. Thus, more the number of simulations, greater is the chance that the results are closer to those of simulation theory.
Thus, option A will be the correct answer.
