one pump, let's call it A, fills the reservoir by 1/60 every hour. Now, B fills it by 1/80 every hour. C empties it by 1/90 every hour. All three are on, so now we combine them into one function: t(1/60 + 1/80 - 1/90) = 1, where t = the time it takes to fill it, and 1 is just our "reservoir finally filled" marker.
isolate t onto one side and we see t = 720/13 exactly, or approximately 55.38 hours. let me know if this is the wrong answer but I'm pretty sure it is correct!
The answer to this problem is 'B'.
This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is
1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3
Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3
Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26
True. To find average monthly income, multiply the net pay by the number of pay periods per year. Then, divide this yearly income by 12 months.
For example:
Daily wages:
Daily wages * 365 days = Total Wage
Total wage / 12 months = average monthly income
Weekly wages:
Weekly wages * 52 weeks = total wage
total wage / 12 months = average monthly income
Answer:
1. Q1=7 Q3=12 IQR=5
2. Q1=8 Q3=33 IQR=25
3. Q1=4.5 Q3=10 IQR=5.5

Answer: None
Step-by-step explanation:
In the given picture , there are two triangles and their corresponding angles are equal.
So by AAA similarity criteria they are similar. But there is no other information is given to prove that they are congruent.
[∵ we know that congruent are similar but similar triangles may not be congruent.]
Therefore, there is no sufficient information to prove them congruent by using any given postulate.
Hence, the answer is "None".
