Answer:
<u>It takes them 30/11 hours to paint them together.</u>
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:
We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:
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):
Therefore, the time it takes them to paint the fence together is <u>30/11 Hours</u>

As a coach for the local soccer team, you want your team to score a goal in the next big game. You look back on last year's stats to make a prediction, with the data shown below the complete table will be
<h3>What is the probability of scoring goals?</h3>
Generally, the equation for the probabilities is mathematically given as
For 1 goal
P(1)= 4/12
For 2 goal
P(2)= 2/12
For 3 goal
P(3)= 2/12
For 4 goal
P(4)= 2/12

Answer:
28.4484
Step-by-step explanation:
Rewrite it in the form a^2 - 2ab + b^2, where a = d and b = 2
d^2 - 2(d)(2) + 2^2
Use the Square of Difference: (a - b)^2 = a^2 - 2ab + b^2
(d - 2)^2
