Ok so you do 3x7= 21 which you already know. So then you do 1x7=7. Last, you just add 21+7=28 pens in total
Answer:
a = A/πb
Step-by-step explanation:
To solve this subject of the formulae given that A = πab.
<u>solution</u>
A = πab
the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a
A = πab
divide both sides by πb
A/πb = πab/πb
A/πb = a
a = A/πb
therefore the value of a in the fomular A = πab is evaluated to be a = A/πb
Answer:
0
Step-by-step explanation:
Your slope would be 0. To find the slope of a line given two points, you find the change in y over the change in x.
In this case, the change in y was 6 - 6 which equals 0.
The change in x was -5 - 2 which was -7.
Since your numerator is 0, 0 divided by anything is automatically equal to 0 no matter what the denominator is.
Therefore, your answer would be 0.
I hope this helped :)
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.
