Answer:
24 minutes.
Step-by-step explanation:
This question shows up in a great many places in math or physics, so it is a pretty good question to learn how to do.
First you should note that answer will be under 40 minutes.
1/40 + 1/60 = 1/TimeTotal
The common denominator on the left is 120 minutes
3/40*3 + 2/60*2 = 1/timetotal
3/120 + 2/120 = 1/ timetotal
5/120 = 1/time total Now to use to the key stop
What you do now is you always turn the left side over. You do the same thing to total time.
120/5 = total time
24 = total time
What this means is that if you let both pipes run for 24 minutes, they will fill the tank working together.
The square root of 125 is in between 11 and 12. It is 11.1803.
Answer:
The first multiple-choice doesn't represent a function
Step-by-step explanation:
(-4,3),(1,-6),(-8,-1),(1,9)
because a function has two pairs with the same x value
*hope that makes sense*
The third one 02 2/5 is the answer
Answer:
Step-by-step explanation:
For this case we have two points given (-1,6) and (1,5)
And we want to complete the point slope equation of the line:
We need to find the slope and we can use the following formula:
And replacing the info we got:
And then the equation would be given by:
And our final answer would be:
