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.
Answer: 2.7 because it’s the introductory
Step-by-step explanation:
-3x^2-2x (+-)6=0
ax^2+bx+c
a=-3
b=-2
c= either positive or negative 6 (there is no plus or minus in your question.)
What are the answer choices? It might help.
The idea for transitions for an equation like this is
![y = m|x - h| + k](https://tex.z-dn.net/?f=%20y%20%3D%20m%7Cx%20-%20h%7C%20%2B%20k%20)
where m = slope
h = how much left or right (note the negative)
k = how much up or down
moving 13 down would mean
k = -13
so
![y = |x| - 13](https://tex.z-dn.net/?f=%20y%20%3D%20%7Cx%7C%20-%2013%20)
D. would be your answer
